TIME-OF-FLIGHT DEPTH CAMERA WITH LOW RESOLUTION PIXEL IMAGING

摘要

A time-of-flight depth camera includes a VCSEL array, an optical arrangement, an evaluator and a light detector having at least one detector pixel. The VCSEL array or the optical arrangement are arranged to provide different illumination patterns in a reference plane in a defined field-of-view of the time-of-flight depth camera. The light detector is arranged to detect the different illumination patterns and the evaluator is arranged to reconstruct a depth image of the field of view with a resolution of a predefined number of pixels P based on the detected different illumination patterns. A number of the detected different illumination patterns N is at least 5% of the predefined number of pixels P, preferably at least 10% of the predefined number of pixels P and most preferred at least 20% of the predefined number of pixels P.
