Point cloud processing method, device and equipment, and computer readable storage medium

Abstract

Embodiments of the invention provide a point cloud processing method, apparatus and device, and a computer readable storage medium. The method comprises steps of constructing a first model and a second model based on obtained point cloud; wherein the first model is arranged in a space formed by the point cloud, and the second model is arranged outside the space formed by the point cloud; expandingand deforming the first model and contracting and deforming the second model; wherein a target distance from the expanded and deformed first model to the point cloud is less than or equal to a firstthreshold, or the target distance from the expanded and deformed first model to the first set is less than or equal to the first threshold; wherein the target distance from the contracted and deformedsecond model to the point cloud is less than or equal to a second threshold, or the target distance from the contracted and deformed second model to the second set is less than or equal to the secondthreshold; wherein the first set comprises point cloud and a second model, and the second set comprises the point cloud and the first model; and fitting and reconstructing a three-dimensional model of the target object based on the point cloud, the deformed first model and the deformed second model.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a point cloud processing method, a point cloud processing device, a point cloud processing device, and a computer-readable storage medium. Background technique [0002] In recent years, with the development of information digital technology, information data has increased significantly both in terms of quantity and dimensionality, especially spatial three-dimensional (3Dimensions, 3D) data has attracted great attention from the industry and researchers, and people are gradually Transform data processing from 2D to 3D research. Among them, 3D modeling is a key step in many 3D technologies, such as virtual reality (Virtual Reality, VR) / augmented reality (Augmented Reality, AR) technology, 3D printing technology, and 3D human body template driving technology. Constructing 3D models from discrete point cloud data in 3D space is the most common 3D modeling problem. ...
