Abstract

The disclosure provides an image processing method and device for a TOF depth image, equipment and a storage medium, and relates to the technical field of camera shooting. The image processing methodfor the depth images shot by the time-of-flight TOF assembly comprises the following steps: respectively obtaining multiple frames of TOF depth images shot based on different configuration values of configuration parameters of a shot scene; respectively extracting effective information in each frame of TOF depth image; and fusing the multiple frames of TOF depth images based on the effective information extracted from each frame of TOF depth image to obtain a high dynamic range HDR depth image. According to the method, the problems of low TOF depth image ranging precision and the like are solved, and the obtained HDR depth image contains richer image details and a higher dynamic range.

Description

technical field [0001] The present disclosure relates to the field of imaging technology, and in particular to an image processing method, device, equipment and storage medium for a TOF depth image. Background technique [0002] Time of Flight (TOF), as a three-dimensional ranging technology for active imaging, measures the time difference between the modulated optical signal emitted by the transmitting module to the target and the echo optical signal received by the receiving module (TOF sensor) Or phase difference to obtain the three-dimensional depth information of the target. [0003] However, due to the influence of factors such as TOF sensor performance and TOF modulation mode, TOF 3D imaging has problems such as low ranging accuracy, limited imaging range, and low spatial resolution. [0004] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and theref...
