=== Project name ===
''Automated extraction of laser streaks and range profiles''

=== Project short description ===
''The aim of this project is to develop an algorithm to extract laser traces produced on various surfaces by a laser scanner from images taken by a camera without IR filter''

=== Laboratory work and risk analysis ===

Laboratory work for this project will be mainly performed at AIRLab/Lambrate. It will include significant amounts of mechanical work as well as of electrical and electronic activity. Potentially risky activities are the following:
* Use of Lasers. Standard safety measures described in [http://airlab.elet.polimi.it/index.php/airlab/content/download/461/4110/file/documento_valutazione_rischi_AIRLab.pdf Safety norms] will be followed.

== '''Part 2: project description''' ==

=== Tasks ===
* Shoot two images with the camera and laser scanner fixed, one with the scanner on and one with the scanner off. Experiment different lighting conditions and camera settings.
* Try subtracting the two images; the trace should be barely visible.
* Equalize and smooth the resulting image
* Return the trace as a set of rectilinear and curvilinear segments.

=== Instrumentation in use (returned 07/08) ===
* Hokuyo Laser scanner  URG-04LX
* Unibrain digital camera + standard 42.5° lens
