基于Opencv的平抛运动教学仪器改进设计

In view of the high school physics horizontal projectile movement experiment, analyzed the shortcomings of existing teaching instrument and teaching process,and improved the structure of the horizontal projectile motion demonstration instrument J2154. Use Opencv visual library and Matlab camera calibration tool to calibrate and correct monocular camera. Design preprocessor for possible light pollution to enhance the adaptability of various lighting environments. The image processing technique in Opencv visual library is used to obtain the moving ball position in real time and output the relevant parameters and charts. The realization of the software and hardware of the flat throwing motion can display the flat throwing motion process intuitively, and the operation is simple and convenient for teaching.
