Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0026] Three-dimensional scanning technology is an advanced fully automatic high-precision three-dimensional scanning technology. By measuring the three-dimensional coordinate values ​​of the surface points of space objects, the point cloud information on the surface of the object is obtained and converted into a three-dimensional model that can be directly processed by the computer, also known as " Reality Replication Technology". Three-dimensional scanning technology is a high-tech that integrates optical, mechanical, electrical and computer technologies. It is mainly us...

Abstract

The present application relates to a three-dimensional scanning turntable adjustment method and device, a computer device and a storage medium. The method includes: acquiring an image of a calibrationunit placed on a turntable and calculating the coordinates of respective points of the calibration unit in the calibration unit image; enabling the coordinates of respective points of the calibrationunit in the calibration unit image to correspond to the actual coordinates of respective points of the calibration unit at a corresponding position one to one; according to the coordinates of respective points of the calibration unit in the calibration unit image, the actual coordinates of respective points of the calibration unit, a corresponding relationship between the coordinates of respective points of the calibration unit in the calibration unit image and the actual coordinates of respective points of the calibration unit, and the optimal rotation parameter of the calibration unit relative to a camera, calculating the rotation angle of a rotating shaft; and adjusting the angle of the turntable according to the rotation angle of the rotating shaft. According to the acquired image, the rotation angle of the rotating shaft is automatically calculated and then adjusted, so that the rotation angle can be calculated more accurately, and the adjustment of the turntable is more precise.

Description

technical field [0001] The present application relates to the technical field of three-dimensional scanning and printing, and in particular to an adjustment method, device, computer equipment and storage medium for a three-dimensional scanning turntable. Background technique [0002] A 3D scanner is used to collect and analyze the geometric structure and appearance data of an object or environment, and perform 3D reconstruction of the collected data to obtain a 3D digital model of the scanned object. These 3D digital models will be used in technical fields such as industrial design, defect detection, reverse engineering, robot guidance, geomorphological measurement, medical information, biological information, criminal identification, digital cultural relic collection, film production, and game creation materials. [0003] In the dental 3D scanner, it is usually hoped that the initial position of the turntable is facing the scanning head, which not only facilitates the selec...
