Full-scene three-dimensional scanning modeling method and device

Abstract

The invention discloses a full-scene three-dimensional scanning modeling method and equipment, and relates to the technical field of scanning modeling, the full-scene three-dimensional scanning modeling equipment comprises a device body, a first rotating assembly is arranged at the top end of a rotating block, a connecting ring is connected to one side of the first rotating assembly, and a scanning device is installed in the connecting ring; the bottom end of the scanning device is connected with a second rotating assembly. By arranging the device body, the first rotating assembly, the second rotating assembly and the scanning device, a second gear disc rotates to drive a third rotating rod to rotate so as to drive a second bevel gear to rotate, the second bevel gear rotates to drive a third bevel gear to rotate, and the third bevel gear rotates to drive a fourth rotating rod to rotate so as to drive the scanning device to rotate. Through two groups of rotation tracks in different axial directions, the scanning device can perform all-directional scanning on the environment in a site, the working efficiency of the device main body is higher than that of manual work, and omission caused by non-scanning in part of regions is avoided.

Description

technical field [0001] The invention relates to the technical field of scanning modeling, in particular to a full-scene three-dimensional scanning modeling method and equipment. 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...

AI Technical Summary

Problems solved by technology

Existing typical indoor scene scanning and modeling usually use multi-depth cameras fixedly placed in different directions around the scene to simultaneously capture the scene from different angles for 3D modeling of the scene, which is costly, bulky and inconvenient to carry; consider Due to the limited field of view of a single depth camera, it is also possible to hold a depth camera to move and scan to obtain multiple perspectives of the indoor scene, and then reconstruct the 3D model of the scene. Although the cost of the equipment is reduced and it is convenient to carry, it requires the operator to hold the depth camera indoors. Moving in the scene, detailed scene scanning is a boring job, especially for large-scale indoor scenes that contain many objects, which is time-consuming and laborious. Due to the movement of the human body, the quality of the scanned data cannot be guaranteed.
