Gateway-based container truck image collection method, system, equipment and storage medium

Abstract

The invention provides a gateway-based container truck image collection method, a system, equipment and a storage medium. The method comprises the following steps: collecting laser point cloud in a gateway region through at least one point cloud collection device, and building a conversion relation between an internal reference coordinate system and a world coordinate system of the point cloud collection device; the to-be-detected laser point cloud projection is converted into a two-dimensional to-be-detected image, and a plane coordinate system is established; collecting laser point cloud when the container truck passes through a gateway area through a point cloud collection device, and projecting and converting the laser point cloud to a two-dimensional to-be-detected image; and when the projection pattern of the container truck in the two-dimensional to-be-detected image reaches a preset triggering position, triggering an image collection device corresponding to the preset triggering position to acquire the image of the container truck. According to the invention, an efficient and accurate space sensing method can be customized for a container gateway, so that more accurate trigger signals are provided for a container truck license plate, a container number recognition system and a photographing system, and the reliability and efficiency of intelligent port management are improved.

Description

Technical field [0001] The present invention relates to the field of AI optical recognition, and in particular, to a brake-based card image acquisition method, a system, a device, and a storage medium for a unmanned pier. Background technique [0002] Container trips are generally located in the port of the port. It is necessary to identify and take pictures with the intelligent management system to identify and take pictures of the past card, which help the port improve management efficiency and reduce labor costs. [0003] The trip gate typically detects the existence of the vehicle and triggers the existence of the vehicle, and triggered the identification and photograph of the trigger. However, these methods have the following problems: the ground coil is buried underground and not easy to repair and replace, more Long construction cycles can cause the tross to be unavailable for a long time. Infrared to the angle of mounting angle, the location requires high, and is suscepti...

AI Technical Summary

Problems solved by technology

[0003] Barrier gates generally detect the presence of vehicles and trigger identification and photographing through methods such as ground sensing coils, infrared radiation, and millimeter wave radar detection. However, these methods have the following problems: the ground sensing coils are buried underground, which is not easy to maintain and replace. The long construction period will cause the barrier gate to be unavailable for a long time

Infrared beaming has high requirements on installation angle and position, and is easily affected by factors such as temperature and light, resulting in a high false alarm rate

Millimeter wave radar is easy to install, but it still has the disadvantages of being susceptible to electromagnetic interference and relatively high power consumption
