Abstract

The invention discloses a 3D image processing method used for improving the denoising capacity during image rendering. The method comprises the steps of clustering collected 3D point clouds to obtain N categories, wherein N is a positive integer, each category corresponds to a plane, and the 3D point clouds are obtained according to a 3D object; making the value of i an integer from 1 to N and determining the normal vector of the ith plane according to the normal vector of each point in the ith plane to obtain the normal vectors of N planes totally; making the value of i an integer from 1 to N and projecting the points in the ith plane into a plane according to the normal vector of the ith plane, wherein the plane is a detection plane corresponding to the ith plane; obtaining N detection planes; rendering the N detection planes to obtain the 3D image corresponding to the 3D object. The invention further discloses a corresponding electronic device.

Description

technical field [0001] The invention relates to the technical field of three-dimensional rendering, in particular to a three-dimensional image processing method and electronic equipment. Background technique [0002] At present, large-scale 3D scene construction is mainly obtained by electronic devices such as 3D cameras. The basic process is to capture a series of depth and color images of the scene through a 3D camera, and then render them. However, the spatial error distribution of the 3D camera is relatively complex, with more noise and messy distribution. How to denoise the 3D image with depth to obtain a 3D image with a more accurate description of the scene is a key issue in scene rendering. [0003] Existing depth image denoising methods are mainly based on time-domain filtering and spatial filtering, that is, the spatial point set is filtered through the distribution of points in the neighborhood of each spatial point. But in a 3D image, there may also be some str...
