Most people have assisted to video-mapping shows where pictures and movies are typically projected using buildings structures as a screen.
We know that pointing a projector to a wall requires some adjustment of its orientation or the correction of the "trapezoidal distortion" (affine transformation) that appears when the optical axis is not perpendicular to the wall plane. When projecting over non-planar surfaces the distortion effects render the projected image hard to understand, depending on the relative position of the projector, the "screen" surface(s) and the viewer.
The objective of this work is to develop an interactive system composed of a Kinect device and a video projector that will be used to project over a table, a slanted wall or even the floor near a robot. Using new low consumption LED-based video projectors it is possible to embed it, together with a Kinect-based device on a mobile robot, that may then use this system to display information on the most appropriate nearby surface.
There are indeed several interesting possibilities for the use of this system like (1) in making the projection over a set of objects and modify their appearance or create a scenario for a game based on the manipulation of these objects, or (2) in industrial contexts.
Although in this work we will aim at develop a game-based rehabilitation tool for stroke patients or elderly people, it will be closely related with an industrial application on the context of an ongoing research project.
This work will be benefit from a current ongoing project and from a collaboration with LAAS-CNRS a large research institution in Toulouse, France.
Depending on the pace of the evolution of the project, the student may be invited to do an internship at LAAS-CNRS co-advised by Prof. Frédéric Lerasle, where the working language can be either English or French depending on the student fluency on these languages.
