一种基于区域约束光流法的扶梯行人逆行检测方法
The method for detecting pedestrians going against the flow on escalators based on region-constrained optical flow extracts corner points within the head area using a target detector and combines this with optical flow tracking and filtering. This solves the problems of high computational complexity and low detection accuracy in existing technologies, achieving efficient and accurate detection of pedestrians going against the flow.

AI Technical Summary
Existing methods for detecting pedestrians going against the flow on escalators suffer from high computational complexity, poor real-time performance, high requirements for camera installation and angle, susceptibility to changes in lighting conditions, and unstable detection accuracy.
The region-constrained optical flow method is adopted, which extracts corner points in the head region through a target detector and combines them with the Lucas-Kanade optical flow method for tracking. The total score is calculated using screening criteria and a circular queue to determine the reverse behavior.
It improves the accuracy and real-time performance of pedestrian wrong-way detection, reduces computational complexity, decreases false alarm rate, and is suitable for deployment in real-world scenarios.
