Abstract :
This paper presents an application of the Raspberry Pi for detecting laser spot using the OpenCV library. To capture the image, a Web-Camera connected to the USB port of the Raspberry Pi is employed. Since the Raspberry Pi is small in size, the module could be mounted on the gun for laser shooting. Compared to the existing laser shooting, our method has benefit in the flexibility of laser shooting mechanism, where the shooter could move the gun freely without the restriction of the camera´s cable connection. The image processing tasks and interfacing to the camera could be accomplished by the Raspberry Pi mounted on the gun. Experimental results show that the proposed system could detect the laser spots under the varying backgrounds, lighting conditions, and shooting distances effectively. The processing speed of 18 fps could be achieved for real time implementation.
