Target recognition system

Abstract

The embodiment of the invention provides a target recognition system. The target identification system comprises a laser scanner used for scanning a to-be-identified material; a driving device connected with the laser scanner and used for driving the laser scanner to rotate according to a preset angle; a control device respectively connected with the laser scanner and the driving device, and used for controlling the driving device to drive the laser scanner to rotate at least once, controlling the laser scanner to scan a to-be-identified material before the laser scanner rotates at least once and after each rotation, receiving scanning data obtained by each time of scanning by the laser scanner, carrying out superposition processing on all the received scanning data to obtain a scanning result, and carrying out target identification according to the scanning result. By adopting the technical scheme of the embodiment of the invention, the accuracy of the scanning result of the laser scanner can be effectively improved under the condition of lower cost, so that the accuracy of target identification is improved.

Description

technical field [0001] The invention relates to the technical field of target recognition, in particular to a target recognition system. Background technique [0002] In the automatic container gantry crane control system, the identification of the lifting container is an essential part. Because laser scanners have many advantages such as strong anti-interference ability and strong environmental adaptability, laser scanners are usually used for target recognition of lifting containers. [0003] Usually, the distance between the installation position of the laser and the container is relatively large, generally up to 15 meters, and the angular resolution of the commonly used laser scanner is generally 0.167°, which causes the scanning error to be over 30 mm. Often can not meet the needs of container target recognition. [0004] In the prior art, target recognition is mainly performed by adding laser scanners or using laser scanners with higher precision, so as to improve th...

Problems solved by technology

[0003] Usually, the distance between the installation position of the laser and the container is relatively large, generally up to 15 meters, and the angular resolution of the commonly used laser scanner is generally 0.167°, which causes the scanning error to be over 30 mm. Often cannot meet the needs of container target recognition

[0004] The existing technology mainly uses laser scanners or laser scanners with higher precision for target recognition to improve the accuracy of scanning data, but this will cause a substantial increase in cost
