Acquisition method and acquisition device of color depth image

Abstract

The present invention discloses an acquisition method and an acquisition device of a color depth image. The acquisition method comprises the steps of collecting first depth data and a color image comprising second depth data in a target area, wherein the accuracy of the first depth data is greater than the accuracy of the second depth data; performing registration on the first depth data and the second depth data; and using an RGB value of the color image as an RGB value of the first depth data by using a registration result, so as to obtain a color depth image of the target area. Through adoption of the method, the RGB value of the color image can be assigned to the first depth data of high accuracy, so as to obtain the color depth image of high accuracy and depth.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an acquisition method and an acquisition device for a color depth image. Background technique [0002] With the continuous development of science and technology and the needs of human beings to understand the world, traditional machine vision can no longer meet people's requirements for three-dimensional object recognition. Compared with grayscale images, depth images have three-dimensional feature information of objects, that is, depth information. Since the depth image is not affected by the irradiation direction of the light source and the emission characteristics of the object surface, and there is no shadow, it can more accurately represent the three-dimensional depth information of the object target surface. [0003] The 3D point cloud (3D image) data obtained by using LIDAR (Light Detection And Ranging, laser detection and measurement), laser beam scannin...
