We focused to develop a beam steering system to track high-speed object movement using the Galvano mirror with CMOS camera. To recognize the special characteristic of the object, color-filtering method is chosen. As the results, the beam steering system can be used to direct the beam to follow object movement speed up to 35°/s. Maximum error position between the central point of object recognition with laser beam spot using color-filtering method without prediction methods is around 2o. To decrease the error position, the prediction method added with system delay factor attached to the color filtering method, this method can decrease the error position less than 0.4o. For OWPT application, we implemented this method to drive small car using this method.
