Abstract

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) reading the 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 quickly generated accurate three-dimensional model.

Description

technical field

[0001] The invention belongs to the field of close-range photogrammetry, relates to a computer vision measurement method, in particular to a measurement method for rapidly recovering a three-dimensional surface model of an object, belongs to the fields of image processing and computer vision, and also belongs to the field of reverse engineering. Background technique

[0002] With the development of information technology, people are increasingly dissatisfied with the existing picture information, and the development of two-dimensional plane information to 3D is the trend. 3D information has incomparable advantages over 2D information in product display and promotion, cultural relics preservation and exhibition, industrial design and manufacturing, and drawing restoration. Therefore, the rapid, real and objective establishment of three-dimensional surface models of objects has attracted more and more attention. At present, 3D modeling generally uses laser sca...
