Panoramic three-dimensional reconstruction system and method based on laser scanning

Abstract

The invention provides a panoramic three-dimensional reconstruction system and method based on laser scanning, the system comprising a control turntable, a camera, a laser emitter, a data processing device and a bracket; the control turntable can be rotated many times according to a preset angle to realize 360 degree circumferential rotation; the camera is used for acquiring an image when the laser beam emitted by the laser emitter irradiates the surface of the object to be reconstructed after the control turntable rotates according to a preset angle each time; the data processing device is used for processing the pictures taken at each angle and calculating the point cloud under the angle, and combining the point cloud to realize the three-dimensional reconstruction of the scanned object;the data processing device is respectively connected with the control turntable, the camera and the laser emitter; the bracket is mounted on the control turntable, and the camera and the laser emitter are mounted on different positions of the bracket. The scheme solves the problems of high manufacturing cost, difficult registration of three-dimensional point cloud, inaccurate conversion of different coordinate systems and the like existing in the prior art.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a laser scanning-based panoramic three-dimensional reconstruction system and method. Background technique [0002] There are many existing 3D reconstruction devices and methods, which are often divided into two categories: contact and non-contact measurement. The typical representative of contact-type three-dimensional measuring equipment is the three-dimensional coordinate measuring instrument. Most of these measuring instruments use mechanical probes and other test heads and sensors to collect more than hundreds of thousands of data points on the surface of the measured object for three-dimensional reconstruction. This method has high measurement accuracy. , but for the reconstruction of indoor or relatively large buildings, there are disadvantages such as the need to design complex driving tooling, slow scanning speed and high manufacturing cost. The ...
