The gradual improvement of the laser pointer application

Do you know what a laser is for? It includes laser pointer, optical flow method, projection device and computer readable storage medium. The position of the light spot in each frame of the screen, according to the position of the light spot in each frame to calculate the speed and direction of the light spot on the screen; If the velocity and direction points are compared on the screen, the velocity and direction of the light spot flow on the screen insert near the interval and the sampling period insert the light flux the spot is placed on the screen; Control the projector surface to display the light flow path of the spot on the screen. With the continuous improvement of laser pointer application, the user experience has been improved, and the convenience of laser projection has also increased. The imaging device detects continuously at pre-set sampling intervals, and the screen image consists of points of light projected from the Laser pointer onto the screen.
