More Information
Summary:The invention discloses a double telecentric projection structured light system which comprises a telecentric imaging module, a telecentric projection module and an image simulation module. The telecentric imaging module, the telecentric projection module and the image simulation module are arranged, adjacent A-level marking dots, B-level marking dots and C-level marking dots are sequentially crossed and connected in series and in parallel, a three-dimensional marking point network is formed, a three-dimensional image of a measured object is made, the three-dimensional marking point network serves as a three-dimensional data mark of the three-dimensional image, and the three-dimensional data mark of the measured object is obtained. The optical three-dimensional measurement precision is ensured; according to the double-telecentric structured light system provided by the invention, the projection lens and the imaging lens both adopt telecentric lenses, so that the uniformity of illumination of the system in the
