Summary:The invention discloses a method for quickly acquiring an object surface model, which comprises the following steps of: (1) automatically controlling the movement of a bearing platform and acquiring qualified sequence images through software; (2) accurately marking a laser plane, a camera parameter and a bearing platform movement space through coordinate of each marking point of a marking block, position of a laser line on the image and relative relationship between an object space point and the laser line; (3) accurately extracting the image coordinate sequence of the laser line; (4) readingthe marking parameter, and obtaining a three-dimensional coordinate point cloud of an object by using forward intersection of triangulation principle; and (5) obtaining a complete three-dimensional model by using Polyworks equal point cloud processing software for editing. The method can quickly reconstruct the three-dimensional surface model of the object, and can judge whether to meet the requirements by using the quick
