Three-dimensional optical scanner

Abstract

The invention relates to the field of three-dimensional scanning, in particular to a three-dimensional optical scanner which comprises a scanning table body, a driving mechanism, a lifting support, arotary adjusting mechanism, a clamping mechanism and a scanning head, the scanning table body is of a circular truncated cone structure, the driving mechanism is installed on the edge of the top of the scanning table body, and the lifting support is fixedly installed on the top of the driving mechanism. A mounting base is fixedly mounted at the end, away from the driving mechanism, of the liftingtype support, a bearing plate is fixedly mounted at the top of the mounting base, a rotary adjusting mechanism is fixedly mounted at the top of the bearing plate, and a scanning head is rotatably mounted on the rotary adjusting mechanism; the driving mechanism is of an annular structure; and a clamping mechanism is fixedly mounted on the scanning table body on the inner side of the driving mechanism; according to the rotation adjusting mechanism, the scanning head is adjusted through the worm and gear, due to the fact that the worm and gear has good self-locking performance, the stability andreliability of the scanning head are better, the stability of an object is guaranteed through the clamping mechanism, and the scanning precision is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional optical scanning, in particular to a three-dimensional optical scanner. Background technique [0002] A 3D scanner (3D scanner) is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often used to perform 3D reconstruction calculations, creating digital models of actual objects in the virtual world. These models have a wide range of uses, such as industrial design, defect detection, reverse engineering, robot guidance, landform measurement, medical information, biological information, criminal identification, digital cultural relic collection, film production, game creation materials, etc. application. The production of 3D scanners does not rely on a single technology. Various reconstruction technologies have their advantages and disadvantag...

AI Technical Summary

Problems solved by technology

Shiny (high albedo), mirror or translucent surfaces are not easily handled by optical techniques, while fragile or perishable surfaces are not suitable for laser techniques

[0003] When using a scanner on a construction site, it is necessary to adjust the angle of the scanner, and the scanning head installed by rotating the rotating shaft is easy to affect the angle of the scanning head during the circular motion scanning process, resulting in poor scanning stability of the scanning head, and scanning The deflection of the scanned product in the process affects the scanning accuracy
