Optical time-of-flight (ToF) sensors are widely used as depth map measurement devices, but their spatial resolution is lower than that of ordinary image sensors.
To solve this problem, we propose a snapshot spatial super-resolution method based on point spread function design and untrained deep neural-network(UDN).
Numerical experiments comparing the proposed method with Bicubic interpolation are conducted, and it is confirmed that the effective resolution and accuracy of the depth map are improved for scenes where the design of the regularization term is compatible. |
