Abstract

The invention relates to a point cloud segmentation method and device, a computer readable storage medium and computer equipment. The method comprises the following steps: encoding a to-be-processed point cloud to obtain a shared feature; decoding the shared feature according to different decoding modes to respectively obtain a semantic feature and an instance feature; matching the semantic features to an instance feature space and then fusing with the instance features, and obtaining semantic fusion instance features; wherein the semantic fusion instance feature represents an instance feature fused with the semantic feature; dividing the semantic fusion instance features to obtain semantic fusion instance features of all points in the point cloud; and according to the semantic fusion instance characteristics of each point, determining an instance type to which each point belongs. According to the scheme provided by the invention, the point cloud segmentation efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a point cloud segmentation method, device, computer-readable storage medium and computer equipment. Background technique [0002] With the development of computer technology, the number of digital images is increasing day by day, and the demand for digital image processing technology is also increasing day by day. A digital image can be specifically represented by a point cloud, and the segmentation processing of a point cloud is also an important branch of digital image processing technology. [0003] At present, when segmenting point clouds such as instance segmentation, it usually relies on feature-based similarity matrix for segmentation, but this method usually takes a long time to segment, resulting in low efficiency of point cloud segmentation, especially It is especially obvious when the number of points in the point cloud is large.
