Embodiment Construction

[0014] refer to figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the point cloud patching system of the present invention. The point cloud patching system 10 runs in an electronic device 100 , which may be a computer, a server, a programmable logic controller (Programmable Logic Controller, PLC), a measuring machine, or other electronic devices with computing capabilities.

[0015] The electronic device 100 further includes components such as a processor 20 , a storage unit 30 and a display unit 40 . The components 10-40 of the electronic device 100 communicate over a system bus.

[0016] The processor 20 is used to execute the point cloud patching system 10 and various software installed in the electronic device 100 , such as an operating system. The storage unit 30 may be a hard disk, or other types of memory cards or storage devices. The storage unit 30 is used for storing various types of data, for example, point cloud data of different pro...

Abstract

The invention provides a point cloud repair method and system. The method comprises introducing point cloud data of a product, receiving point spacing and a curvature filtering parameter which are input by a user, determining a to-be-repaired area in the point cloud data and the minimum bounding box of the to-be-repaired area, selecting a preset number of points in the minimum bounding box and outside the to-be-repaired area, fitting the selected points into a B-spline surface, performing interpolations on the B-spline surface according to the point spacing to obtain a plurality of discrete points, filling the to-be-repaired area with the discrete points, determining and deleting unorganized points of the to-be-repaired area according to the point spacing and the curvature filtering parameter, and performing smoothing processing on the point cloud data after filling when other to-be-repaired areas do not exist in the point cloud data. High-precision repairing of a missing point cloud can be achieved.

Description

technical field [0001] The invention relates to a point cloud processing method and system, in particular to a method and system for repairing missing point clouds. Background technique [0002] When the 3D scanning device scans the product to be measured to generate a point cloud, due to the scanning device itself or the interference of other external factors, the point cloud will be missing in the position that the 3D scanning device is difficult to scan and the position with a marker point. In the existing point cloud processing system, point cloud repair generally uses a simple point cloud to fit the missing surface, and uses points on the surface to fill in the missing points. This point cloud repair method is likely to cause obvious filling traces in the missing parts, and may lead to distortion and deformation of the point cloud. Contents of the invention [0003] In view of the above, it is necessary to provide a point cloud repair method and system that can reali...
