Complete set of equipment and surveying and mapping method for 3D laser scanner applied to faro software

Abstract

The invention discloses a complete set of equipment and a surveying and mapping method for a three-dimensional laser scanner applied to FARO software. It is applied in the field of three-dimensional laser scanners and solves the technical problem of low scanning accuracy in the scanning process. The key points of the technical scheme include three-dimensional laser scanning instrument, a total station, and a coordinate conversion device, the coordinate conversion device includes a tripod, a U-shaped base connected to the tripod, the base is provided with a cross-shaped connecting frame, and the horizontal section of the connecting frame is rotatably connected to the On the base, the two sides of the vertical section of the connecting frame are respectively connected with a reference ball and a prism, and the midpoint of the line between the center of the reference ball and the center of the prism is located at the horizontal section of the connecting frame The axial direction; the technical effect is that it can more accurately present the environment inside the workshop in a three-dimensional way.

Description

technical field [0001] The invention relates to the field of three-dimensional laser scanners, more specifically, it relates to a complete set of three-dimensional laser scanner equipment and a surveying and mapping method applied to FARO software. Background technique [0002] Three-dimensional laser scanning technology is also called real scene replication technology. It uses high-speed laser scanning measurement method to quickly obtain three-dimensional coordinate data of the surface of the measured object in a large area and high resolution. It can quickly and massively collect spatial point information, providing a new technical means for quickly establishing a 3D image model of an object. [0003] The 3D imaging of the 3D laser scanner has a range. When the factory workshop is being transformed, multiple measurements are required. Each measurement will form a 3D map. Find a common coordinate in these 3D maps so that the 3D maps overlap. , so that a complete three-dim...

Problems solved by technology

However, when the axial direction of the scanner and the ring is staggered, the ring becomes an ellipse during the imaging process. At this time, the coordinate table for measuring the center of the ring will not be accurate enough, resulting in the integration of multiple three-dimensional images. Sometimes, the different 3D images cannot be completely overlapped, which brings inconvenience to the follow-up work
