基于OpenCV光流法的电梯逆行检测

Owing to the fact that breakdown of escalator(escalator goes the wrong direction) occurred frequently these years, that fact became a focus problem. This paper put forward a real time and automatic video monitor solution to provide effective early warning. Its function: data collected from escalator video monitor is processed on a PC, first of all, a polygon is drawn by mouse to specify the operation region, then the real time direction that the escalator is going in that region is detected by codebook and motion detect algorithm, in the end, the result is outputted to VGA display device, if the real time direction of the escalator is not right, warnings will be shown on the VGA display device.
