Correction method, electronic equipment and computer readable storage medium

Abstract

The invention discloses a correction method, electronic equipment and a computer readable storage medium. The correction method comprises the following steps: acquiring an original depth map, acquiring a depth phase difference of each pixel in the image sensor according to a preset relation and coordinate values of pixel points in the original depth map, and acquiring a correction depth value of each pixel according to the depth phase difference of the pixel and an original depth value of the pixel. The original depth map comprises a plurality of pixel points, each pixel point in the original depth map is in one-to-one correspondence with each pixel of the image sensor, and the original depth value of each pixel point in the original depth map is the original depth value of each corresponding pixel; the preset relationship reflects a depth phase difference between the original depth map and the corrected depth map and a relationship between coordinate values of pixel points in the original depth map, the corrected depth map comprises a plurality of pixel points, and the pixel points in the corrected depth map are in one-to-one correspondence with the pixels of the image sensor; the corrected depth value of each pixel point in the corrected depth map is the theoretical depth value of each corresponding pixel.

Description

technical field [0001] The present application relates to the technical field of distance measurement, and more specifically, to a calibration method, electronic equipment, and a computer-readable storage medium. Background technique [0002] At present, some electronic devices have ranging functions, such as ranging through ToF depth cameras. However, the measurement accuracy of the ToF depth camera will be inaccurate under the influence of internal factors of the depth camera system. Specifically, due to the difference between each pixel of the light receiver of the ToF depth camera, there are differences in parameters such as the time when each pixel receives a signal and the time of exposure delay, resulting in inaccurate measurement results. Contents of the invention [0003] Embodiments of the present application provide a calibration method, electronic equipment, and a computer-readable storage medium. [0004] The correction method of the embodiment of the presen...
