The present invention belongs to the field of three-dimensional map construction, and discloses a three-dimensional map reconstruction system and method based on the RFID and the laser radar. The reconstruction system comprises: an RFID card reader, an RFID tag, a laser radar, a mobile platform and a controller. The RFID tag is arranged on a to-be-identified object; the RFID card reader is configured to identify the RFID tag, determine the position of the RFID tag, and transmit the information to the controller; the laser radar is configured to scan a to-be-reconstructed area to construct a two-dimensional map, and transmit the two-dimensional map to the controller; and the controller is configured to find a three-dimensional model matching the RFID tag in the database according to the RFID tag, and map the three-dimensional model to the corresponding position in the two-dimensional map according to the position of the be-identified object, so as to generate a three-dimensional map ofthe to-be-reconstructed area. The present invention also discloses a three-dimensional map generation method by using the system. According to the technical scheme of the present invention, the construction of the three-dimensional map at a low cost is realized in a convenient and quick manner.
Description
technical field [0001] The invention belongs to the field of three-dimensional map construction, and more specifically, relates to a three-dimensional map reconstruction system and method based on RFID and laser radar. Background technique [0002] With the introduction of intelligent manufacturing, in order to improve production efficiency and quality, intelligent chemical factories came into being. The mobile platform suitable for intelligent chemical factories, especially the AGV car, plays a pivotal role in this. At present, the AGV mobile platform has been widely used in the transportation of materials and the carrier of mobile robotic arms. To realize the positioning of AGV in transportation and realize the trajectory planning in processing, it is necessary to consider the construction of the environmental map. How to realize high-efficiency, high-precision, flexible, and low-cost map construction is of great significance to actual production. [0003] Patent CN2015...
