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.

Claim (Index 1):
A video monitoring apparatus for an operating state of a wave maker, the video monitoring apparatus comprising a computer, a camera with a fixed focus lens, a tripod with a pan-tilt, some red round LEDs and a driving control circuit board, wherein the camera is fixed to the tripod with pan-tilt and arranged on the outer side of an experimental pool; an optical axis forms a certain angle with the movement direction of wave paddles and is connected with the computer through a transmission cable; a red round LED is arranged on each wave paddle in a visual region, and each LED is connected to the driving control circuit board; the driving control circuit board of the LED is connected with the computer through a RS232 interface; each wave paddle can be seen as a mark point; when the operating state of the wave maker is monitored, an image collected by the 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.
