The Jet Closed-Loop Control Method Based on Image Processing

Abstract

The existing water cannons are basically open-loop control, which can not provide real-time feedback on the position difference between the shooting flow point and the target, especially for the moving target, there is a large strike error. The jet closed-loop control technology is an important way to realize the accurate and continuous strike of water cannon on target. Considering only the influence of gravity and air resistance, a jet closed -loop control method is proposed. In this method, the horizontal Angle and pitch Angle of the water cannon are adjusted by geometric calculation and the jet motion trajectory model are established respectively. On the basis of image processing, a method to adjust the Angle of the water cannon again is designed, and the feasibility of this method is verified by a lot of simulation experiments. Experiments show that this method can dynamically adjust the jet Angle in real time according to the target bearing, and has high accuracy and real time.
