Abstract

This application is applicable to the field of computer application technologies, and provides a depth compensation method of a direct time of flight dTOF sensor and an electronic device. The method includes: in response to a trigger operation for a camera application, driving the dTOF sensor to collect raw image data; obtaining a current real drive voltage of a single-photon avalanche diode SPAD in the dTOF sensor; obtaining a current expected drive voltage of the SPAD; and performing depth compensation on the raw image data based on the real drive voltage and the expected drive voltage, to generate a target depth map. Therefore, a depth information deviation caused by a regulation error of a drive voltage of the SPAD is corrected based on a deviation between a real value and a theoretical value of the drive voltage of the SPAD, to improve accuracy of depth information collected by the dTOF sensor, thereby improving distance measurement accuracy of the dTOF sensor.
