Abstract

The paper presents the development of shooting simulator using the embedded camera based-on Omnivision OV6620. The proposed system provides a simple and low cost embedded system to detect the laser spot in the shooting simulator. The proposed system employs the circular target as the shooting target. The embedded system is installed inside the target box behind the target screen. Once the target screen is illuminated by the laser spot, the embedded camera detects the position of laser spot, and sends the position to the computer for calculating the shooting score. The color tracking is performed in the embedded system by comparing the values of red, green, and blue colors with the thresholds defined in advance. The experimental results show that the system could calculate the shooting score properly. Further, to provide an easy calibration of the camera’s position, the computer could read a whole image captured by the camera for further processing.
