Problems solved by technology
At present, the three-dimensional reconstruction technology of line laser is mostly single-sided scanning. Due to the characteristics of line laser itself, the uniformity of line laser irradiation cannot be guaranteed for objects with large curvature. Although pure image reconstruction can realize scanning of objects with large curvature, it cannot. fine reconstruction

The invention discloses a multifunctional three-dimensional measurement and reconstruction system and method based on line structured light. The reconstruction system includes a support, a first acquisition component, a controller and a data processing device. A support platform and a support platform are fixedly installed on the support. The first guide rail has a tray on the support platform, the tray is rotatably installed on the support platform, the first collection assembly is movably installed on the first guide rail, the first collection The components include a first laser group and a first camera group, and the controller is used to control the rotation of the tray, the movement and acquisition of the first acquisition component, so that the three-dimensional measurement and reconstruction system can operate in the first scanning mode and the second scanning mode. Switch between two scan modes. The present invention adopts two different scanning modes, the axial scanning reconstruction mode is adopted for shaft-shaped objects, and the circumferential scanning is adopted for objects with large curvature, so as to realize targeted fine reconstruction.
Description
Technical field [0001] The present invention relates to the field of three-dimensional modeling techniques, and more particularly to a multi-function three-dimensional measurement reconstruction system and method based on line structure light. Background technique [0002] The three-dimensional laser scanning technique can provide three-dimensional dot cloud data for scanning object surfaces, so it can be used to obtain a high-precision high resolution digital terrain model, which is the principle of laser ranging, by recording a large number of dense points of the measured object surface Information such as three-dimensional coordinates, reflectance and texture, etc., can quickly recover various three-dimensional models and lines, faces, and body, etc. of the target. General three-dimensional laser scanning system contains part of the hardware portion and data processing of data acquisition. At present, the three-dimensional reconstruction technique of the line laser is a single...
