Problems with unwanted objects in the process of obtaining points: In addition to the offset capabilities of the device, it self and the travel point algorithm, unwanted parts of objects may appear in the initial point cloud.Problems in obtaining target effects: For example, the task of obtaining a goodquality triangular face model suitable for grouping yielded 2.5 billion points, calculating the maximum number of triangles of 100,000 (doors or windows open).Instead, broadband Internet access is required to transmit data to the data center for processing.
