Abstract

The invention relates to the field of 3 dimensional digital imaging and in particular to a 3 dimensional measuring method having multi-measuring modes. The method includes the following steps: S1. establishing a unified data structure model which is intended for uniformly representing measurement data acquired through the multi-measuring modes; S2. under each single measuring mode, using the uniform data structure to represent each point cloud obtained through measurement, and performing computing and pre-processing; S3. splicing the data acquired through the different measuring modes, aligning two point clouds at any position to a uniform coordinate system; S4. conducting hybrid global optimization on the spliced data to obtain the result of measurement. According to the invention, the 3 dimensional measuring method can achieve real-time fusion and optimization of the measured data under the multi-measuring modes, achieve 3 dimensional measurement with high precision and great details, and has wide applications.

Description

technical field

[0001] The invention relates to the field of three-dimensional digital imaging, in particular to a three-dimensional measurement method with multiple measurement modes. Background technique

[0002] The technology of non-contact three-dimensional measurement of the surface of objects has been widely used in many fields such as industry, medical treatment, art, and education. Applications in different fields have different technical requirements for 3D measurement. For example, the automobile industry requires high accuracy of 3D measurement data and clear data details; 3D measurement of human body requires fast acquisition of 3D data of human body, requires the measurement system to have a handheld function, and requires low precision; 3D measurement of large sculptures requires the measurement system to have Handheld function, at the same time, the data accuracy is high, and the data has certain details.

[0003] None of the currently known 3D scanners and...
