Abstract

The invention provides a depth map processing method and device, and the method comprises the steps: obtaining a first depth image frame and a second depth image frame adjacent to the first depth image frame; determining a first content value of each first pixel and a second content value of the corresponding second pixel, and obtaining a content difference between the first content value and thesecond content value; determining a credible pixel in the first depth image frame according to the content difference, and determining the area of a region where the credible pixel is located; and when the area of the region meets a preset condition, adjusting an acquisition interval of the depth image frame according to the area of the region, and obtaining a next to-be-processed depth image frame according to the acquisition interval. Therefore, the sampling interval of the image frame is determined based on the area of the area where the depth value changes gently, and the calculation amount of time consistency filtering is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a depth map processing method and device. Background technique [0002] Generally, when measuring the depth of an object based on a Time of Flight (ToF) sensor, the ToF sensor determines the distance between the sensor and the object by calculating the flight time of the pulse signal, and then determines the depth value of the object based on the distance. [0003] In the related art, all depth image frames are traversed to perform filtering processing, which results in a large amount of computation for filtering processing of the depth image frames. Contents of the invention [0004] The present invention aims at at least to a certain extent to solve the problem in the related art that traversing all the depth image frames for filtering processing results in a large amount of calculation for the filtering processing of the depth image frames. [0005] Therefo...
