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

摘要

The invention describes a time-of-flight depth camera (200) comprising a VCSEL array (100), an optical arrangement (210), an evaluator (255) and a light detector (220) comprising at least one detector pixel (222), wherein the VCSEL array (100) or the optical arrangement (210) are arranged to provide different illumination patterns (20) in a reference plane in a defined field-of-view (300) of the time-of-flight depth camera (200), wherein the light detector (220) is arranged to detect the different illumination patterns (20), wherein the evaluator (255) is arranged to reconstruct a depth image (50) of the field of view (300) with a resolution of a predefined number of pixels P based on the detected different illumination patterns (20), wherein a number of the detected different illumination patterns (20) 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.;The invention further relates to method of performing a time of flight measurement and to a corresponding computer program product.
