Abstract

The invention relates to a three-dimensional point cloud data registration method and a stitching method. The three-dimensional point cloud data registration method comprises steps: first point cloud data and second point cloud data correspondingly obtained when a three-dimensional scanning device scans calibration target objective space comprising multiple target balls at a first visual angle and a second visual angle respectively are acquired, wherein the calibration target is always placed at the same position in a common scanning area between the first visual angle and the second visual angle when the three-dimensional scanning device performs scanning at the first visual angle and the second visual angle respectively; in the first point cloud data and the second point cloud data, a first ball center point cloud and a second ball center point cloud are found out respectively, wherein both the first ball center point cloud and the second ball center point cloud contain ball center coordinates of all target balls in the calibration target; and according to the conversion relationship between the first ball center point cloud and the second ball center point cloud, the first point cloud data and the second point cloud data are registered to the same coordinate system. The method uses the calibration target as a bridge for matching of data scanned at two visual angles, the imaging aberration degree of a target ball surface is smaller than that of a plane, and the registration accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a three-dimensional point cloud data registration method and splicing method. Background technique [0002] Housing measurement is an important part of construction engineering and home improvement design engineering. It is a highly professional job. If there is a problem in the calculation of the building area, it will have a direct impact on the accuracy of the budgeted cost, which will bring a lot of manpower, material loss. The 3D laser scanner is a non-contact method of acquiring large amounts of high-precision data, which can obtain the digital model of the interior of the house. However, the rooms in the house are separated by walls, and each room is a relatively independent space. The registration between the obtained 3D point cloud data of each room is difficult. [0003] The traditional 3D point cloud registration method is usually completed by pasting marke...
