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

[0029] see Figure 1-6 , an embodiment provided by the present invention: a three-dimensional laser scanner for engineering survey, comprising a three-dimensional laser scanner body 1, a base 2, a tripod 3 and a lithium battery 4, the three-dimensional laser scanner body 1 is rotatably mounted on the base 2. The upper end and the bottom end of the base 2 are fixedly equipped with a tripod 3, and the three-dimensional laser scanner body 1 is powered by a lithium battery 4;

[0030]The three-dimensional laser scanner body 1 includes a casing 101, a laser radar 102, a filter mirror 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 mirror 103 is facing to the left and right, and the right side wall of the optical filter 103 is fixed with a rotating shaft 109, and the right end of the rotating shaft 109 is fixed with a transmission wheel 110, and the left side wall of the transmission wheel 110 is pro...

Embodiment 2

[0036] On the basis of Example 1, such as figure 1 and Figure 10 As shown, a glass vial 209 is embedded on the upper surface of the base 2, and the accuracy of the glass vial 209 is 30', which can rotate around the axis to maintain accuracy.

[0037] During implementation of this embodiment, the setting of the glass vial 209 is convenient for judging whether the three-dimensional laser scanner is in a horizontal state, which can effectively reduce the error of the scanning result, and the cost of the glass vial 209 is low.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a three-dimensional laser scanner for engineering measurement. 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, and by recording the 3D coordinates, reflectivity, texture and other information of a large number of dense points on the surface of the measured object, it can quickly reconstruct the 3D model of the measured target and various lines, surfaces, and volumes. kinds of map data. Since the 3D laser scanning system can intensively acquire a large number of data points of the target object, compared with the traditional single point measurement, the 3D laser scanning technology is also known as a revolutionary technological breakthrough from single point measurement...
