Abstract

The invention relates to the field of three-dimensional digital imaging, and particularly relates to a three-dimensional measurement system with multiple measurement modes. The three-dimensional measurement system comprises a control unit, a variable digital pattern generation unit, an image processing unit, a calculation unit and at least one image sensor, wherein the control unit is used for controlling coordination work of the whole measurement system; the variable digital pattern generation unit comprises a memory and a projector, the memory stores a plurality of optical template digital patterns, and the projector is used for projecting the digital patterns in the memory onto the surface of a measured object; the image sensor is used for acquiring a pattern projected onto the surface of the measured object; the image processing unit is a multi-mode digital image processor; and the calculation unit is a multi-mode three-dimensional point cloud calculator. The three-dimensional measurement system with multiple measurement modes can achieve high-precision and high-detail three-dimensional measurement or hand-held real-time measurement for the surfaces of different measured objects through switching the measurement modes, and has a wide application range.

Description

technical field [0001] The invention relates to the field of three-dimensional digital imaging and modeling, in particular to a three-dimensional measurement system 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...
