A pseudo-dToF imaging method using an iToF image sensor composed of multi-tap macro-pixels in combination with compressive sensing is presented. This method can reproduce the received light waveforms as in the dToF based on single-photon avalanche diodes (SPADs) while maintaining high spatial and temporal resolution. By applying the oversampling to the reconstruction, the received light waveforms are reconstructed with higher temporal resolution. Experimental results showed that distance precision was improved by the proposed method. |
