Optical Synchronization of ToF cameras

The aim of the project is the development of a new optical method for the activity detection of ToF sensors and their synchronization. A variety of application scenarios requires the parallel use of multiple ToF cameras. There is a problem: In contrast to conventional cameras, the ToF sensors work actively and send out light in the infrared spectrum for measurement purposes. If the actively illuminated areas of two ToF sensors overlap during the measurement, this leads to falsified results. Therefore, when using multiple ToF sensors with a common field of view, it is necessary to synchronize the lighting- and recording times. The project will develop and test suitable frame- and impulse-based synchronization methods.
