Embodiment Construction

[0031] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0032] Because the three-dimensional measuring device in the prior art cannot meet the technical problems of all-round three-dimensional measurement and fast mapping. In order to solve the above technical problems, the first embodiment of the present invention provides an all-round three-dimensional point cloud map generation system, which ge...

Abstract

The present invention discloses an omnibearing three-dimensional point cloud map generation method and system. The system comprises a control calculation unit, a rotation laser unit and a speedometerunit. The rotation laser unit comprises a first rotation motor, a second rotation motor and a diastimeter. The diastimeter collects single-point point cloud data, the rotating speeds of the two rotating motors are controllable and collect poses corresponding to the point cloud, and the speedometer unit collects speedometer data, the control calculation unit performs processing of the collected single-point point cloud data, the poses and the speedometer data to generate local maps. An output shaft of the second rotation motor is fixedly connected with the first rotation motor in the system, anoutput shaft of the first rotation motor is provided with the diastimeter, the rotation direction of the first rotation motor is mutually perpendicular to the rotation direction of the second rotation motor, and under the action of the first rotation motor and the second rotation motor, the diastimeter can perform omnibearing laser scanning to obtain three-dimensional point cloud data in each direction and generate the local map in each direction.

Description

technical field [0001] The invention relates to the field of omnidirectional monitoring, in particular to a method and system for generating an omnidirectional three-dimensional point cloud map. Background technique [0002] With the rapid development of special robots and intelligent manufacturing industries, more and more intelligent devices are put into complex and unstructured working environments, and the demand for real-time three-dimensional perception and measurement is increasing. Among the current various three-dimensional measurement devices, LiDAR is widely used due to its high precision and good stability. Due to the small vertical viewing angle of the traditional multi-line laser radar, it can only cover the area where the laser scanning line is located, and cannot meet the needs of all-round three-dimensional measurement. Swing and splicing the measurement data in each pose to obtain a high-density spatial three-dimensional point cloud. [0003] In the exist...
