Patent ID: 10605694

Abstract:
The present invention belongs to the technical field of movement monitoring, and provides a video monitoring apparatus and method for an operating state of a wave maker. When the operating state of the wave maker is monitored, an image collected by a camera is subjected to mark point detection and a central position is computed. Then, the position of each mark point is tracked in a dynamic video; and the operating condition of each wave paddle is assessed according to the motion state of the mark point. In the present invention, operating monitoring of the wave paddle is independent of a wave making control system, and the operating condition of the wave paddle is monitored in real time through a non-contact image measurement mode. The wave paddle is identified through LED; the positions of the mark points in each frame image are acquired through image perspective correction and binarization analysis; and the operating state of the wave paddle is judged according to the contrast among the mark points at different times and different spatial positions, thereby effectively reducing an error rate of the wave making control system for the operating monitoring of the wave paddle and greatly increasing experimental efficiency of simulating wave making.
