  • Publication number: 20220084336
    Abstract: This disclosure provides a vehicle inspection method, apparatus, system, and computer-readable storage medium and relates to the field of security inspection technologies. The vehicle inspection method of the present disclosure includes: acquiring vehicle profile information of a vehicle through a first sensor that performs measurement in a direction perpendicular to a passage, and determining a feature point of the vehicle according to the vehicle profile information; determining a position of the vehicle in the passage through a second sensor that performs measurement in a direction along the passage, and determining a position of the feature point according to the position of the vehicle in the passage; and switching an operating mode of a ray source based on a preset strategy according to a position relation between the position of the feature point and the ray source.

  • Patent number: 10495661
    Abstract: The present disclosure relates to a method and a device for monitoring a state of a moving object and a system for fast inspecting a vehicle. The method and a device for monitoring a state of a moving object positions and measures speed of the moving object by using a laser scanner. The device includes: a laser scanner configured to monitor at least one moving object entering a monitoring region, by emitting a plurality of laser beams of different angles to the at least one moving object with a preset scanning frequency; and a processing unit configured to, for each moving object, determine and output a relative position of the moving object with respect to the laser scanner at each time instance. It can significantly improve the accuracy of measuring a low speed of the moving object, and the laser scanner is easy to install and has a low cost.
