Implementation of a 1440Hz video projector for calibrating optic flow sensors at high speed

In this paper, the results of experiments in which a high velocity movement is simulated using digital light processing methods (with a Digital Light Processing (DLP) video projector) are presented. The main aim is to simulate a fast movement in order to test optic flow (OF) sensors or event-based sensor more quickly and simply than with traditional methods based on moving wallpaper or LCD screen. To obtain an accurate movement resolution, specific pictures are generated and displayed by the DLP at a high frame rate. The results show that accurate projected movement speeds are obtained with velocities of up to 50m/s. Propositions to increase these results are discussed.
