CristianoAlessandro: /* The AIRLab */

Welcome to AIRWiki!
AIRWiki is AIRLab's [http://en.wikipedia.org/wiki/Wiki wiki]. AIRLab is the '''Artificial Intelligence and Robotics Laboratory''' of the '''Politecnico di Milano''' University (Italy).

AIRWiki was born as a tool for teachers, researchers and students to share information about projects in an easy and quick way. However, it quickly evolved into a display of the activities of AIRLab too: you are invited to browse this wiki, to discover what we work on.

If you are looking for a description of what the AIRLab is, who works in it, and what scientific interests they have, the best place is the [http://www.airlab.elet.polimi.it/ AIRLab website]; but if you want an overview of what we are actually ''doing'', AIRWiki is the right place!

== Research areas ==
At the AIRLab we work on a very broad range of topics, organized in these areas:
* [[Agents, Multiagent Systems, Agencies]]
* [[BioSignal Analysis]]
* [[Computer Vision and Image Analysis]]
* [[E-Science]]
* [[Machine Learning]]
* [[Ontologies and Semantic Web]]
* [[Philosophy of Artificial Intelligence]]
* [[Robotics]]
* [[Soft Computing]]
These areas are described in detail on [http://www.airlab.elet.polimi.it/index.php/airlab/research_areas this page] of [http://www.airlab.elet.polimi.it/ AIRLab's website].

== Projects ==
Research work in the above areas is done within '''projects'''. Details about active and finished projects are available at the [[Projects]] page. Ongoing projects are covered as soon as enough - and structured enough - information about them is available.

Information about how to set up and manage a project page can be found at [[Projects - HOWTO]].

== Project Proposals (for courses, theses, ...) ==
Proposals of course or thesis projects for students are available at the following pages:

[[First Level Course Projects]]

[[First Level Theses]]

[[Master Level Course Projects]]

[[Master Level Theses]]

If you are interested in any proposal you can contact the tutors by email.

== How do I access the contents of this wiki? ==
AIRWiki is conceptually composed of two layers:
* a '''public layer''', readable by everyone on the internet and modifiable by AIRWiki's [[Registered users]];
* a '''private layer''', reserved to the [[Registered users]] (who can read and edit its contents).
More information about how such layers are actually implemented and how to access the private layer is available in the [[Layers]] page.

The public layer of AIRWiki is relatively stable: it is mainly constituted by documentation about past and ongoing projects, accessible through the [[Projects]] page. In addition to that, it includes useful information about the AIRLab (see [[#The AIRLab]]) and tutorials for AIRLab users (see [[#AIRLab survival guide]]).

The private layer is used by the people working on the projects as a repository of all the information related to them. Much of this information will eventually be suitably formatted and moved to the public layer.

== How can I contribute? ==
Contribution to the wiki (i.e. creation and modification of pages) is limited to [[Registered users]].

If you are a registered user and have information you want to share (description of what you do, links to useful sources of information, HOWTOs, and so on) just publish them on AIRWiki: it's easy and - dare we say it? - fun! As a guideline, consider putting on AIRWiki everything ''you'' would have liked to find there... instead of being forced to find out the hard way. And everything future students who will build upon your work would like to find.

At [[Projects - HOWTO]] you can find instructions and guidelines about how to set up a page for the project you work on and how to add new information to it.

Moreover, a wiki always needs help in terms of maintenance, linking between pages, shaping of a structure and so on. And well, in this very moment it also needs a logo ;-) If you want to help please send an email to either migliore (at) elet (dot) polimi (dot) it or eynard (at) elet (dot) polimi (dot) it.

== The AIRLab ==
Work (generally speaking) is done somewhere, using something and to reach some goal ;-) For the AIRLab, the following links tell you...
* ...where: [[The Labs]]
* ...using what: [[What's in the AIRLab]]
* ...why: [[Projects]]

If you want details about who the professors and researchers working at the AIRLab are and what scientific work they do, just go to the [http://www.airlab.elet.polimi.it/ AIRLab website].

Some experiments require external controlled conditions (no mobiles must ring, no people have to talk...) and particular instruments( [[Electroencephalographs]], [[ProComp Infiniti]]). If this is the case, you can book the [[IIT-Lab]] (of course you have to be registered first!).

== AIRLab survival guide ==
Some things are neither scientific nor technical, but you must know them all the same to work in the AIRLab...
* [[Bureaucracy]] (administrative procedures)
* [[Tips'n'tricks]] (things that can save you much trouble)
* [[AIRLab rules]] (they are few and simple, but you have to follow them)

As we are on the subject of survival (read: how to avoid hurting yourself or others), remember that '''to work in the AIRLab you must know the [[Safety norms]] and comply with them'''.

What's in the AIRLab

2008-10-07T14:27:14Z

CristianoAlessandro:

This page is used to keep track of all the hardware (oh well, at least of the main gear) that you can find in the various AIRLab sites (a list of which is given in [[The Labs]]). The gear is divided into categories, and you must go to the relevant one to know what is available, its main characteristics, and where it is now.

As we are on the topic of "where things are", please keep in mind that ''other'' people want to find things as much as ''you'' want that, so '''if you are moving something away from its current location please update the relevant table THIS INSTANT''' >:-). If you don't know where you are taking it, just put your name in the table, so at least the others will know who to ask (or who to hunt for).

Remember that there are '''risks''' associated to the use of some kinds of hardware. They are described, along with the instructions to avoid them, in the [[Safety norms]]. You are '''required''' to know these norms, and you have full responsibility for anything you do in the AIRLab.

Cameras, lenses and mirrors

2008-07-01T22:05:55Z

CristianoAlessandro:

==IMPORTANT NOTES==
'''Never touch the sensor element (CCD or CMOS) of a camera with anything!''' It can very easily be scratched.

'''Never touch the glass elements of a lens with your hands!''' The oil from human skin is harmful.

==Cameras and frame grabbers==
===Cameras===
In the AIRLab you can find different kind of cameras. These are the main groups:
*'''Analogue cameras'''. Video output is given as an electrical signal, which needs analogue-to-digital conversion to be processed by a computer; this is done by a specific card called ''frame grabber'' or ''video capture card'' (the latter tend to be the lowest-performance items; see [[Cameras, lenses and mirrors#Frame grabbers]] for details). Analogue video is outdated for computer vision and robotics applications, due to its cost, low performance and complexity; nowadays digital camera systems (such as all the ones listed below) are always preferred.
*'''USB cameras'''. Usually very cheap, they are suitable for low-performance applications (i.e. those where low frame rate is needed and low image quality can be accepted). Their main advantage (along with cost) is the fact that every modern computer has USB ports. The fact that the USB standard includes 5V DC power supply lines helps simplifying camera design and use.
*'''FireWire cameras'''. The FireWire (or IEEE1394) bus is generally used for low-end industrial cameras, i.e. devices with technical characteristics much superior to those typical of USB cameras but low-performance according to typical machine vision standards. Industrial cameras usually give to the user a much wider control over the acquisition parameters compared to consumer cameras, and therefore they are usually preferred in robotics; their downside is the higher cost. There are different versions of IEE1394 link (see http://en.wikipedia.org/wiki/Firewire for details), with different bitrates, starting from the 400Mbit/s FireWire 400. Generally they are all considered superior to USB 2.0, even if theoretical bandwidth is lower for FireWire 400. Firewire ports can include power supply lines, but some interfaces (and in particular those on portable computers) omit them. Although the use of FireWire interfaces has expanded in recent years, they are not yet considered a standard feature for motherboards.
*'''GigE Vision cameras'''. GigE Vision (or Gigabit Ethernet Vision) is a rather new connection standard for machine vision, based upon the established Ethernet protocol in its Gigabit (i.e. 1000Mbps) version. It is very interesting, as complex multiple-camera systems can be easily built using existing (Gigabit) Ethernet hardware, such as cables and switches. Vision data is acquired simply through a generic Ethernet port, commonly found on motherboards or easily added. However, 100Mbps (or ''fast Ethernet'') ports are not guaranteed to work and can sustain only modest video streams; on the other hand, 1000Mbps ports are now standard on motherboards, so this will not be a problem anymore in a few years. It seems that GigE Vision is becoming the most common interface for low- to medium-performance industrial cameras.
*'''CameraLink cameras'''. Cameralink is a high-speed interface expressly developed for high-performance machine vision applications. It is a point-to-point link, i.e. a CameraLink connection is used to connect a single camera to a digital acquisition card (''frame grabber''). Its diffusion is limited to applications where extreme frame rates ''and'' resolutions are needed, because CameraLink gear is very expensive.

The following is a list of the cameras available in the AIRLab. (To be precise, it is a list of the cameras that are modern enough to be useful.) For each of them the main specifications (and a link to the full specifications) are given. Details on the different types of lens mount are given below in [[Cameras, lenses and mirrors#Lenses]]. The 'how many?' field tells if multiple, identical items are available. Finally, the 'where?' field tells you in which of the AIRLab sites (listed in [[The Labs]]) you can find an item, and the 'project' field is used to specify which project (if any) is using it.

Ah, one last thing. People like to actually ''find'' things when they look for them, so '''don't forget to update the table when you move something away from its current location'''. If you don't know where you are taking it, just put your name in the table.

==Camcorder==
In the AIRLab you can find also a ''memory camcorder'', i.e. a consumer camera system that records (lossy) compressed digital video onto standard SD flash memory cards. It's a [http://www.samsung.com/uk/support/download/supportDown.do?group=homeentertainment&type=camcorder&subtype=flashcamcorder&model_nm=VP-MX10&prd_ia_cd=03110800&disp_nm=VP-MX10&mType=&dType=D&vType=R Samsung - VP-MX10H] and can be used to record on video demos, lessons or talks. It is fitted with an 8GB SD card, i.e. the biggest it can be used with.

Main features:
* maximum resolution 720x576 pixel (progressive scan), the same as DVD
* MPEG4 encoding (Mplayer for Linux, for example, plays it back perfectly)
* 2.7" 16:9 LCD Display (but recorded image format is 4:3)
* 34x Optical zoom (1200x with digital zoom)
* image stabilizer (use it if you go over, say, 4x of zoom factor)
* USB connection to PC (it's seen as a mass storage device)
* maximum usable SD card capacity 8GB
* 220' of video on an 8GB card in best-quality mode
* 120' (claimed) battery duration (with fully charged battery, during recording and if you don't play much with the zoom)
* unreliable battery charge indicator :-(
* battery discharges quickly even when the device is off, so be sure to recharge it before use

Where: now the camera is in the [[User:DavideMigliore]] office.

===Frame grabbers===
As previously said, a '''frame grabber''' is an electronic board that connects to one or more cameras, and converts the signals from the cameras into a data stream that can be elaborated by a computer. They are usually designed as expansion boards to be fitted into the computer case. Frame grabbers are necessary for ''analogue cameras'' (as they include the analogue/digital converters) or for CameraLink digital cameras (in this case the frame grabber is essentially a high speed dedicated digital interface). Other kinds of digital cameras don't need a frame grabber: this is one of the main advantages of digital cameras over analogue ones in machine vision applications, where the processing is almost always performed by computers.
In the AIRLab two models of frame grabber are available:
*a digital frame grabber from Euresys, model Expert 2, having two CameraLink inputs (http://www.euresys.com/Products/grablink/GrablinkSeries.asp). ''Notes: needs a PCI-X slot; one of the inputs is not working due to a fault.''
*two multichannel analogue frame grabbers from Matrox, model Meteor II/Multi-Channel, having three analogue inputs that can be combined into a single three-channel RGB analogue input (http://www.matrox.com/imaging/support/old_products/home.cfm). ''Note: one item is permanently mounted on the MO.RO.1 robot: see [[The MO.RO. family]] for details.''
*two multichannel analogue frame grabbers from Matrox, model Meteor II/Multi-Channel, having three analogue inputs that can be combined into a single three-channel RGB analogue input (http://www.matrox.com/imaging/support/old_products/home.cfm). ''Note: one item is permanently mounted on the MO.RO.1 robot: see [[The MO.RO. family]] for details.''
*two single-channel analogue frame grabbers from Matrox, models Meteor and Meteor Pro (http://www.matrox.com/imaging/support/old_products/home.cfm).
All the frame grabbers (except the one on the MO.RO.1) are currently in AIRLab/DEI. If you move one of them, please '''write it down here'''... and do it NOW!

==Lenses==
Industrial cameras usually have interchangeable lenses. This allows for the choice of the lens that is more suitable to the considered application. There are two main standards for industrial camera lenses: '''C-mount''' and '''CS-mount'''. Both are screw-type mounts. CS-mount is simply a modified C-mount where the distance between the back of the lens and the sensor element (CCD or CMOS) is shorter: therefore a C-mount lens can be mounted on a CS-mount camera if an ''adapter ring'' (i.e. a distancing cylinder with suitable threads) is placed between them. It is impossible, though, to use a CS-mount lens on a C-mount camera: if you try you will almost certainly break the sensor, scratch the lens, or both. Just because a lens fits a camera, it doesn't mean it can be actually mounted on it!

At the AIRLab we also use lenses specifically designed for Unibrain's ''board cameras'': they are very simple, with no iris, and very small. Their mounting system is an M12x0.5 metric screw thread.

Be aware that sensor dimension (i.e. its diagonal, measured in fractions of an inch) is ''not'' the same for all cameras. Therefore one of the key specifications for a lens is the maximum sensor dimension supported. If you use a given lens with too big a sensor, the edges of the image will be black as they lie outside the circle of the projected image. Also beware of the strange convention used for sensor diagonals, i.e. a fraction in the form A/B" where A and B are integer ''or non-integer'' numbers. For instance an 1/2" sensor is smaller than an 1/1.8" one.
The variability of sensor dimensions has another side effect: the same lens has a different angle of view if you change the sensor size. Therefore the same lens can behave as a wide-angle with a large sensor and as a telephoto with a small sensor.

An useful guide to lenses (in Italian or English) can be found at http://www.rapitron.it/guidaob.htm.

The following is a list of the actual lenses available in the AIRLab. For each of them the main specifications (and a link to the maker's or vendor's page for full specifications) are given. A '?' means an unknown parameter: if you know its value or experimentally find out it when using the lens (e.g. the maximum sensor size), please ''update the table'' before the information is lost again! Lenses having 'M12x0.5' in Column 'mount type' are only usable with Unibrain's Fire-i board cameras. A 'YES' in the 'Mpixel' column indicates a so-called ''Megapixel lens'', i.e. a high quality, low-distortion lens designed for high-resolution industrial cameras (typically having large sensors); please note that some of these are specifically designed for B/W (i.e. black and white) cameras. The 'how many?' field tells if multiple, identical items are available. Finally, the 'where?' field tells you in which of the AIRLab sites (listed in [[The Labs]]) you can find an item, and the 'project' field is used to specify which project (if any) is using it.

Ah, one last thing. People like to actually ''find'' things when they look for them, so '''don't forget to update the table when you move something away from its current location'''. If you don't know where you are bringing it, just put your name in the table.

==Mirrors==
Much work has been done and is being done at the AIRLab on the topic of '''omnidirectional (machine) vision''' (sometimes referred to as ''omnivision''). Omnidirectional vision systems use special hardware to overcome the limitations of conventional vision systems in terms of field of view. The approach to this problem that we generally adopt is the use of conventional cameras in association with convex '''mirrors''', i.e. the capturing of the image reflected by a suitably-shaped mirror with a camera. The possibility of designing mirrors with specific geometric properties gives a very useful means to control the geometric behaviour of the whole camera+mirror system.

TODO for someone who knows better ;-) : mirror list
