Study on Target Recognition Methods in Velocity Experiment Using High Speed Camera



At present in the shooting field experiment, commonly use high-speed camera shoot to projectile or debris flying process, and obtain the speed of moving objects by processing image frame. This method is more simple and efficient than the aluminum foil method, net target method, and can restore the flight path. How to deal with the image frame is the key of this method. For a group of a projectile flight image frame as an example, different classical algorithms are used to deal with the frames. Combine the different methods with the complex characteristics of the experimental environment and improve this method. The results show that the target can be extracted better and clouds, shadows, dust and other noise can be filtered.
