The invention discloses a method for splicing three-dimensional data of product measurement. The method comprises the steps of: fixing a product on a fixation fixture; controlling a three-dimensionalscanner to scan a product; recording a scanning path of the three-dimensional scanner and a movement trajectory of a mobile control device in the complete scanning process of the product by a main controller; dismounting the product on the fixation fixture and then installing a calibration gauge; controlling the three-dimensional scanner and the mobile control device to carry out same scanning andposition controlling on the calibration gauge based on the recorded scanning path and movement trajectory by the main controller; with certain data in the point cloud data of the calibration gauge asa reference, carrying out splicing and integration on the plurality of point cloud data of the calibration gauge; and compensating the splicing of the point cloud data of the product with a constraint value in splicing of the point cloud data of the calibration gauge correspondingly to complete the splicing of the product point cloud data. Therefore, the product structure can be scanned completely; the integrity of the product scanning is guaranteed; and the work efficiency is improved substantially.
Description
technical field [0001] The invention relates to the field of three-dimensional detection, in particular to a method for splicing product measurement three-dimensional data. Background technique [0002] 3D scanning technology is the basis of 3D spatial data modeling and is widely used in various industries. The existing 3D scanning technology obtains point sets in 3D space through multiple scans by scanning instruments at different viewing angles, which is called point cloud data, and then converts the point cloud data from each viewing angle into the same 3D coordinate system for point cloud data splicing, and finally forms 3D scanned point cloud data. [0003] Existing glass panel inspection equipment adopts this three-dimensional scanning technology to inspect glass products, which can accurately detect glass panels and detect structures accurately. Existing glass panel inspection equipment includes a scanning instrument for scanning and measuring products, a fixture de...
