The laser has a special characteristic to develop Optical Wireless Power Transmission (OWPT) for long distance. It provides a coherent almost non-divergent beam with high energy density in a small beam size of diameter. This condition makes the direction of the laser beam to the appropriate target using laser beam steering system is needed. In this research, we focused to develop a beam steering system to track high-speed object movement using computer vision to control the Galvano mirror. To recognize the special characteristic of the object, color filtering method is chosen. The enhancement of this system is using prediction calculation based on accelerated uniform motion theory to reduce the error. As the results, this system can reduce the error angle using this method up to 98% at 27.35 deg/s object speed.
