AI Technical Summary

Technical Problem

Existing turnstile equipment is inefficient in the process of personnel passage, especially when facial recognition fails, which leads to a longer time for people to stay. In addition, the camera's data collection effect is affected by external environmental interference or incorrect posture of pedestrians.

Method used

The system tracks pedestrian trajectories using a first camera, dynamically calls multiple second-view cameras to capture pedestrian images, and combines local and remote models for recognition. Multiple strategies are employed to optimize camera usage, including acquisition area level, proximity, resolution, and hierarchical calling, to ensure the accuracy of image acquisition and recognition.

Benefits of technology

It improved the efficiency of gate passage, reduced the time people spent at the gate, improved recognition efficiency and accuracy, and optimized resource utilization.

Abstract

The invention discloses a linkage calling passing inspection method of a customs clearance camera, which is used for controlling calling of a first camera and a plurality of second cameras, the first camera is used for shooting an image of a pedestrian at a first visual angle, and the second cameras are used for shooting an image of the pedestrian at a second visual angle; the method comprises the following steps: a first camera tracks and records a plurality of first view angle images when a pedestrian approaches a gate; forming a pedestrian prediction track in a preset detection area of the first camera according to the first view angle images at the multiple different moments, and calling at least one second camera on the pedestrian prediction track; a second camera obtains a second visual angle image of the pedestrian and recognizes the second visual angle image and preset face information, and if recognition succeeds, a preset gate is controlled to be opened; and if the identification is wrong, closing the gate, and collecting the biological information of the pedestrian for verification. According to the linkage calling passing checking method, the calling efficiency of the camera module is effectively improved, and the passing efficiency of pedestrians is improved.
