Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples will be used in conjunction with the accompanying drawings to further describe the 3D laser scanner and the method for acquiring 3D information of the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "righ...

Abstract

The invention relates to the technical field of scanning equipment, in particular to a 3D laser scanner. The 3D laser scanner comprises a bracket, an industrial camera, a linear laser, and a power source. The industrial camera and the linear laser are arranged on the bracket. The power source is in transmission connection with the bracket, and is used for driving the industrial camera and the linear laser to coaxially and synchronously rotate in the horizontal and/or vertical direction(s). The linear laser is used for emitting laser to the surface of a target to be measured. The industrial camera is used for acquiring laser reflected from the surface of a target to be measured. The 3D laser scanner combines the linear laser and the industrial camera. The linear laser emits laser to the surface of the target to be measured, and the industrial camera acquires a laser image. The industrial camera and the linear laser can synchronously rotate in the horizontal and vertical directions. Thus, a whole space can be scanned, and 3D data of the whole space is obtained finally. The 3D laser scanner has high precision, is simple to operate, and is suitable for indoor space scanning reconstruction. The invention further relates to a method for acquiring 3D information.

Description

technical field [0001] The invention relates to the technical field of scanning equipment, in particular to a three-dimensional laser scanner and a method for acquiring three-dimensional information. Background technique [0002] In traditional interior decoration, various crafts are generally realized manually. In some decoration techniques such as wall putty polishing, if it is done manually, the construction quality will be uneven, so the realization by robots will be an inevitable trend. In the automatic wall grinding of the decoration robot, one of the key technologies is the positioning of the robot. The so-called positioning of the robot is where the robot is in the room at a certain moment, and where it is relative to the wall. The positioning of the robot requires a positioning sensor so that the decoration robot can obtain indoor positioning information. The technical solutions for indoor positioning of robots include: ultrasonic positioning system, infrared pos...
