Research on Shipborne Visual Water Cannon Target Locking Technology
When the shipborne water cannon strikes the dynamic target,it often lags behind because of the flying time of the water column.The visual water cannon designed in this paper carries on the target detection and recognition through the vision sys-tem,locates the target,and designs the loss early warning module and the redetection method to realize the robust tracking for a long time.The target trajectory is predicted,and the prediction mathematical model is established through the trajectory curve slope characteristic equation,and the lock of the target is realized by calculating the advance amount.In 100 trajectory tests,when the rel-ative velocity of the target is 5 knots,the coincidence degree can reach 92.3%.In the application,this technology effectively solves the lag phenomenon when the visual water cannon hits the moving target.
