The article presents a list of projects developed for the course of 2D Vision Systems during the year 2014-2015.
The first project was developed by Simone Formichella, with the aim of developing a small vision system to detect objects on a rotating table using a NI1764 smart camera.
One of the problems the student faced was how to detect reflective objects with optical sensors and how to deal with the transparency of the rotating plate. Moreover, the smart camera was able to perform only lightweight elaborations, so the system had to be splitted between camera and the host PC, which was able to perform the more computational heavy processing required. The whole system was developed using LabView.
The second project was developed by Alessandro Nastro, with the aim of using a very low cost projector to project fringes for 3D reconstruction.
The student created a triangulation system with two Basler Scout scA1390 cameras and a low cost projector (Philips PicoPix PPX22505). The student dealt with the camera 2D calibration performed by a custom made VI developed in LabView in order to correctly detect the fringes projected on the image and retrieve the period between them. In this way it is possibile to perform a 3D reconstruction of an object!
The third project was developed by Pietro Craighero with the aim of measuring the inner and the outer radius of a mechanical object using telecentric lenses.
Telecentric lenses allow users to obtain images with high contrast with almost no image distorsion, thus being a fundamental piece of any high accuracy vision system. The student created a small set-up with a red-light laser and a telecentric camera, used to acquire 2D images of the object to be measured. The software used for the project was developed in LabView.
