Problems solved by technology

However, in practical applications, it is found that unless there is an accurate angle measurement device, the user is not sensitive to the angle, and it is difficult to determine the angle accurately; the size of the target object is difficult to accurately determine, especially in some applications where the target objec

Abstract

The invention provides a multi-region three-dimensional model generation method and device. The method comprises the following steps: acquiring multiple groups of images A of a first region of a target object by using an image acquisition device; acquiring a plurality of groups of images B of a second region of the target object; acquiring a plurality of groups of images C of a third region of thetarget object by using the image acquisition device; wherein the third region is a region where the first region and the second region of the target object are connected; wherein the multiple groupsof images A, the multiple groups of images B and the multiple groups of images C can be used for synthesizing a target object 3D model. It is proposed for the first time that complete information of atarget object is collected in a transition collection mode, so that real 3D model construction is achieved, and three-dimensional information of the real volume range of the target object is obtainedinstead of only three-dimensional information of the surface of the target object. And more information (such as thickness) of the target object can be measured.

Description

technical field [0001] The invention relates to the technical field of shape measurement, in particular to the technical field of 3D shape measurement. Background technique [0002] When performing 3D measurement, using 3D measurement data for processing and manufacturing, or using 3D data for display and identification, a relatively accurate 3D model should first be established for the target object. The currently commonly used methods include using machine vision to collect pictures of objects from different angles, and matching and splicing these pictures to form a 3D model. However, the usual 3D acquisition is performed on the object surface. For example, construct a 3D model of an antique vase, use a camera to capture images from multiple angles of the antique vase, and then use a 3D modeling algorithm to synthesize the 3D model of the vase. However, the 3D model constructed in this way is only the surface of the vase, and does not realize real 3D modeling, nor can so...
