Annular high-precision measuring device and method based on speckle structured light

Abstract

The invention discloses an annular high-precision measuring device and method based on speckle structured light. The annular high-precision measuring device comprises a supporting structure, an annular guide rail connected to one end of the supporting structure, a cantilever rotationally connected to the lower end of the annular guide rail, a depth camera module assembly which is vertically connected to the cantilever, and a servo system, wherein the servo system is arranged above the annular guide rail and fixed to the supporting structure, and an output end of the servo system is connected with the cantilever. According to the annular high-precision measuring device and the method, annular scanning can be carried out in the horizontal direction, linear scanning can be carried out in thevertical direction, texture reconstruction and appearance reconstruction can be carried out on the target object in a short time, authenticity and integrity of external texture features of a reconstruction model are improved, and application scenes are expanded.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a ring-shaped high-precision measurement device and method based on speckle structured light. Background technique [0002] With the development of computer vision technology, 3D reconstruction technology based on laser vision has been fully developed, but the current 3D reconstruction technology does not have strong scene adaptability, often ignores the technical indicators requirements in specific scenes, and cannot be vertical to various industries. Subdivided areas for deep integration. The present invention is mainly aimed at some specific industries such as: medical beauty, teaching, 3D printing, etc. The above industries not only have higher requirements on the accuracy of 3D reconstruction, but also pay attention to whether the external texture features of the reconstructed model are real and whether the reconstructed model is complete. , whether the r...

Problems solved by technology

[0002]With the development of computer vision technology, 3D reconstruction technology based on laser vision has been fully developed, but the current 3D reconstruction technology does not have strong scene adaptability, The technical index requirements in specific scenarios are often ignored, and it cannot be deeply integrated with vertical segments of various industries

This invention is mainly aimed at some specific industries such as: medical aesthetics, teaching, 3D printing, etc. The above-mentioned industries not only have high requirements for the accuracy of 3D reconstruction, but more importantly, pay attention to whether the external texture features of the reconstructed model are real and whether the reconstructed model is complete , whether the restoration degree of the model is high, the commonly used 3D reconstruction solutions cannot meet the above indicators at the same time
