Construction and Integration of under vehicle inspection system based on multi-source sensors

In order to realize the independent innovation and upgrade technology of customs and other departments, an under-vehicle inspection (UVI) system based on multisource sensors is researched and developed in this paper. The system fuses four types of sensors (camera, hyperspectral instrument, microphone, infrared meter), and is integrated into the mobile intelligent detection system platform to form an intelligent target detection system. The four types of sensors can obtain the feature information of specific objects from shape, material and structure respectively, and display them in the form of pictures. After the completion of system coordination and integration, in March 2019, the multi-source sensors UVI system was applied in the Turgart custom of Xinjiang region. In the application testing, the test tasks are better completed. The hardware and software of the system are stable, the detection speed is fast, and the recognition accuracy is high. It can effectively improve the vehicle chassis target detection ability in complex real scenes, and provide mature target detection system and solution for customs field.
