Problems solved by technology

[0003] However, the amount of point cloud data collected by laser scanners or depth cameras is huge, which is not convenient for storage, transmission and subsequent processing. For example, the scale of point cloud directly determines the efficiency of reconstruction, so it is necessary to simplify the fusion process of point cloud

Abstract

The embodiment of the invention discloses a point cloud fusion method and device, electronic equipment and a computer storage medium, and the method comprises the steps: determining the depth confidence of a pixel point in a current frame depth map according to at least two types of impact factors in scene information and/or camera information, wherein the scene information and the camera information respectively comprise at least one influence factor; and performing point cloud fusion processing on the pixel points in the current frame depth map according to the depth confidence. Thus, in theembodiment of the invention, the depth confidence coefficient of the pixel point can be determined by comprehensively considering various factors, so that the reliability of the depth confidence coefficient can be improved, and the reliability of point cloud fusion processing can be further improved.

Description

technical field [0001] The present disclosure relates to computer vision technology, and in particular to a point cloud fusion method, device, electronic equipment and computer storage medium, which can be applied to 3D modeling, 3D scenes, augmented reality and other scenarios. Background technique [0002] Using a laser scanner or a depth camera, a large amount of point cloud data can be collected to realize the reconstruction of a 3D model of an object or scene. This 3D model reconstruction method based on point cloud data can be used for augmented reality and games on mobile platforms In other applications, for example, it can realize functions such as online display of 3D objects and scene interaction, shadow projection, interactive collision, etc., and can also realize functions such as 3D object recognition in the field of computer vision. [0003] However, the amount of point cloud data collected by laser scanners or depth cameras is huge, which is not convenient for...
