The invention relates to a mobile laser radar slam drawing device and a data processing method, and the device comprises a satellite signal receiving unit which is used for receiving a satellite positioning signal and is connected with a data collection sensing unit, an IMU inertial measurement unit and a drawing collection calculation unit, and achieves the transmission of positioning and time synchronization information; a data acquisition sensing unit which is used for capturing image information in a certain space-time area and sending the acquired image information to a drawing acquisition and calculation unit; an IMU inertial measurement unit which is connected with the drawing acquisition and calculation unit and is used for sending the data to the drawing acquisition and calculation unit and acquiring accurate GPS time information sent by the satellite signal receiving unit; and the drawing acquisition and calculation unit which is used for providing a plurality of data interfaces to acquire the original data of the data acquisition and sensing unit in a multi-thread mode so as to realize multi-sensor fused slam drawing. According to the invention, modular design can be realized, a high-integration acquisition system is provided, and the system is convenient to carry, disassemble, assemble, maintain and replace.
Description
technical field [0001] The invention relates to a laser radar navigation and positioning processing method, in particular to a mobile laser radar slam mapping device and a data processing method. Background technique [0002] Slam (Simultaneous Localization And Mapping) technology refers to real-time positioning and map construction, that is, by processing the surrounding environment data collected by sensors, real-time feedback of the current position of the motion system in the unknown environment and drawing the surrounding environment map of the motion system at the same time. With the development of lidar technology, mobile SLAM mapping systems have shown broad application prospects in forestry, transportation, mine roads, construction and other fields. [0003] Although slam technology is used in many scenarios, there is very little technology in this area in terms of mapping and data processing of multi-sensor acquisition through slam technology, and how to stably fus...
