Problems solved by technology

[0002] Three-dimensional scanning technology is widely used in engineering survey, medical field, construction, cultural relics protection field, deformation monitoring of geological disasters, etc. Portable 3D digital scanner can be set up in complex geographical environment, and it can also scan in batches for oversized objects , so that the three-dimensional scanning technology is in an important position in various fields, and has become the mainstream of three-dimensional alphanumeric information technology. 3D scanners, to a certain extent, limit the popularization and application of 3D scanning technology in domestic unknown fields
For objects in the order of meters, it is difficult for the Eora 3D scanner to scan the experimental object in all directions, and there are dead spots in the scan
This device cannot complete the precise scanning of the upper part of the object, and the use conditions are relatively single, which cannot meet the scanning requirements in various situations, and there is still a certain gap between the accuracy required in engineering practice

Embodiment 1

[0035] When the three-dimensional laser scanning device of the present invention scans small and movable objects, the specific operation steps are as follows:

[0036] Step 1: Put the object to be measured on the placement plate and fix it in a good position, adjust the small vertical adjustment support, adjust the vertical adjustment rod, so that the object to be scanned is at a suitable height;

[0037] Step 2: Turn on the CCD camera I for shape acquisition and the CCD camera II for color acquisition, turn on the carbon dioxide laser emitter, adjust the relative position of the imaging device and the laser emitting device on the semi-circular slide rail, adjust the imaging device and the laser The corner of the emitter irradiates the laser on the scanned object, and the above parameters are input into the computer to calibrate the scanning device;

[0038] Step 3: Open the bottom rotating disk controller in the computer, input a certain speed, control the bottom rotating dis...

Embodiment 2

[0046] When the three-dimensional laser scanning device of the present invention scans the entire indoor space, the specific operation steps are as follows:

[0047] Step 1: Put away the place where the object is placed, and adjust the vertical adjustment lever so that the scanning device is in a suitable position for the entire indoor space;

[0048] Step 2: Turn on the CCD camera I for shape acquisition and the CCD camera II for color acquisition, turn on the carbon dioxide laser emitter, adjust the relative position of the imaging device and the laser emitting device on the semi-circular slide rail, adjust the imaging device and the laser The corner of the emitter irradiates the laser light into the indoor space accurately and clearly, and input the above parameters into the computer to calibrate the scanning device;

[0049] Step 3: Open the bottom rotating disk controller in the computer, input a certain speed, control the bottom rotating disk to rotate 360°, and perform ...

Abstract

The present invention relates to a system and method of an experiment of a three-dimensional laser scanner for indoor simulation test. The system comprises a distance measurement and imaging device, adirection regulation device, an object putting place, a bottom transmission device and a data processing system. The distance measurement and imaging device comprises a laser transmission device andan imaging device; the direction regulation device comprises a semi-circular slide rail, a rotation slide ring, a rotation drive, a vertical regulation rod and a bottom rotation disc; the object putting place comprises a putting disc and a mini-type vertical regulation supporting base; the bottom transmission device comprises a portion holder, universal rollers and a fixed boot; and the data processing system comprises data processing software and an AUTOCAD. Point cloud data is generated to perform error elimination to construct a triangulation network, the multiple point cloud is subjected to color covering, and finally a result is output. The scanner can perform accurate scanning for most of common objects and can be widely arranged in the indoor simulation test.
