In order to improve and guarantee the quality of products, it is essential to carry out inspections on products. At the same time, the increasing and urgent inspection requirements require enterprises to implement product inspections quickly and accurately. φ Early detection of the test object, generally using a specific test instrument, after manual comparison to determine the test value. In recent years, with the improvement of computer hardware performance and price reduction, computers have been introduced in a large number of test objects, thus improving the speed and accuracy of inspection. The method generally uses a scanning machine to scan a test object, and obtains a set of points consisting of a plurality of three-dimensional discrete points, generally called a point cloud, and the point cloud data is sent to a computer, and the corresponding software is processed to process the point cloud data. For example, point cloud measurement, color scale comparison, etc., to achieve the test of the object under test. However, the point cloud obtained by the scanning machine after scanning the object under test is not exactly the point cloud of the object to be tested, which may include a part of the machine, etc. The editing of the point cloud is generally performed in the I-dimensional space. There is still a big difference between the edited point cloud and the point cloud of the object under test, so there is a certain error when testing the object under test. Therefore, it is necessary to provide a point cloud three-dimensional processing system and method, which can view a point cloud from different angles in a three-dimensional space, and edit the point cloud, thereby
