Problems solved by technology

In the later maintenance process of the 3D laser scanner of this utility model, only one of the panels needs to be disassembled from the shell frame. Its structure is simple, easy to disassemble or install, and the cost is low; Everywhere, for example: the motor drives the filter to do a continuous 360° rotation, and the filter will only scan the external object for half a circle during the rotation of the filter, so the scanning efficiency is low and the time is long

Embodiment 1

[0036] see Figure 1-6 , an embodiment provided by the present invention: a mobile 3D laser scanner based on lidar and panoramic camera, including a 3D laser scanner body 1, a base 2, a tripod 3 and a lithium battery 4, the 3D laser scanner body 1. It is rotatably installed on the upper end of the base 2, the bottom end of the base 2 is fixedly installed with a tripod 3, and the three-dimensional laser scanner body 1 is powered by a lithium battery 4;

[0037] The three-dimensional laser scanner body 1 includes a casing 101, a lidar 102, a filter 103, a first speed sensor 104, a first motor 105, a panoramic camera 106, a time counter 107 and a central processing unit 108; the lidar 102 and the filter The mirror 103 is arranged facing right and left, the right side wall of the filter 103 is fixed with a rotating shaft 109, the right end of the rotating shaft 109 is fixed with a transmission wheel 110, the left side wall of the transmission wheel 110 is provided with a circular ...

Embodiment 2

[0043] On the basis of Example 1, as figure 1 and Figure 10 As shown, a glass vial 209 is embedded on the upper surface of the base 2, and the glass vial 209 has an accuracy of 30' and can rotate around the axis to maintain the accuracy.

[0044] In the implementation of this embodiment, the setting of the glass level bubble 209 is convenient for determining whether the three-dimensional laser scanner is in a horizontal state, which can effectively reduce the error of the scanning result, and the construction cost of the glass level bubble 209 is low.

Abstract

The invention relates to the technical field of engineering measurement, in particular to a mobile three-dimensional laser scanner based on a laser radar and a panoramic camera, comprising a three-dimensional laser scanner body, a base, a tripod and a lithium battery. The three-dimensional laser scanner body is rotatably mounted on the base. The upper end of the seat and the bottom end of the base are fixed with a tripod, and the body of the 3D laser scanner is powered by a lithium battery; the body of the 3D laser scanner includes a chassis, a lidar, a filter, a first speed sensor, a first motor, a panoramic camera, Time counter and central processing unit; the upper surface of the base is rotatably installed with a turntable, the lower surface of the turntable is fixed with a ring-shaped rack, the upper surface of the base is also provided with a rectangular groove, and the interior of the rectangular groove is installed with a second motor and a second motor Speed ​​sensor; the invention can improve the scanning speed, save the scanning time, and can adjust the horizontal rotation speed at the same time to realize back and forth scanning in the same vertical plane.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a mobile three-dimensional laser scanner based on a laser radar and a panoramic camera. Background technique [0002] Three-dimensional laser scanning technology is a new technology that has emerged in recent years, and it has attracted more and more attention in the research field in China. It uses the principle of laser ranging, by recording the three-dimensional coordinates, reflectivity and texture of a large number of dense points on the surface of the measured object, it can quickly reconstruct the three-dimensional model of the measured object and various lines, surfaces, volumes, etc. image data. Since the 3D laser scanning system can obtain a large number of data points of the target object intensively, compared with the traditional single-point measurement, the 3D laser scanning technology is also known as a revolutionary technological breakthrough from...
