A three-dimensional measurement scheme based on time-of-flight method using multi-aperture image capturing system, which can give temporally coded exposure for each aperture individually by programming shutter pattern for each block of pixel array is proposed. The measurement frequency is enhanced on the basis of compressive sensing technology by capturing multiple temporally coded images simultaneously. The results of preliminary experiments are presented to confirm measurement of the phase of a light signal modulated at a higher frequency than the frame rate of the image sensor. |
