Abstract:

This paper proposes the laser extraction system by adjusting camera parameters. This system is based on presentation tool with laser pointer, and it detects the laser spot overlapped with projection image by CCD/CMOS camera. In this research, we confirmed the method of extracting laser spot from projection image by adjusting camera parameters. We determined essential parameters and optimal threshold to extracting laser spot. We constructed the prototype system, and showed its effectiveness by laser spot extraction experiments. As a result, our proposal made it possible to extract the laser spot effectively regardless of the background image.
