THREE-DIMENSIONAL MODEL CONSTRUCTION AND MEASUREMENT METHOD BASED ON COORDINATE MEASUREMENT

摘要

A three-dimensional (3D) modeling method having coordinate information, comprising (1) collecting a plurality of images of a target object by using a collection device; (2) determining a plurality of specific points from the plurality of images; (3) finding corresponding points on the target object according to the specific points in the images to serve as calibration points; and measuring coordinates of the calibration points on the target object; and (4) constructing, by using the plurality of images and the coordinates of the calibration points, a 3D model having coordinate information. Further provided is a 3D modeling device having the coordinate information. Absolute size calibration of the target object is implemented by means of a method for performing laser ranging and angle measurement on a plurality of points.
