Problems solved by technology

However, the cost of 3D laser scanners in the prior art is very high. For example, the price of an outdoor 3D laser scanner with a measurement distance of more than 150 is more than 1 million, which is difficult to popularize.

Abstract

The present invention belongs to the detection technical field and discloses a three-dimensional laser scanning device and method. The device comprises a two-dimensional laser scanner used for performing two-dimensional scanning on an object to be measured and providing scanning contour point cloud data of the object to be measured, a rotary table used for performing rotation operation and providing rotation angle data, a fixing structure used for fixing the two-dimensional laser scanner to the rotary table, and a controller which is used for controlling the operation of the two-dimensional laser scanner and the rotary table and receiving the scanning contour point cloud data and the rotation angle data, and is also used for obtaining three-dimensional point cloud coordinate data of the object to be measured according to the scanning contour point cloud data and the rotation angle data. With the three-dimensional laser scanning device and method of the invention adopted, longitudinal line scanning and left-right plane scanning can be carried out, so that a three-dimensional plane scanning function can be realized. Since the two-dimensional laser scanner is used, cost can be greatly reduced, and cost performance is high.

Description

technical field [0001] The present invention relates to the technical field of detection, in particular to a three-dimensional laser scanning device and method. Background technique [0002] Laser ranging uses a laser as a light source for ranging, and is divided into continuous lasers and pulsed lasers according to the way the laser works. Gas lasers such as helium-neon, argon ions, and krypton-cadmium work in a continuous output state and are used for phase laser ranging; double heterogeneous gallium arsenide semiconductor lasers are used for infrared ranging; solid-state lasers such as ruby ​​and neodymium glass are used for Pulsed laser ranging. Compared with the photoelectric rangefinder, the laser rangefinder can not only work day and night, but also improve the distance measurement accuracy and significantly reduce the weight and power consumption, making it a reality to measure the distance to distant targets such as artificial earth satellites and the moon.
