A Computer Tracking System Of Solar Dish With Two-axis Degree Freedoms Based On Picture Processing Of Bar Shadow

摘要

The sun tracking system of a solar dish based on computer image processing of a bar shadow is investigated. This is done by using a camera to obtain the optimized picture of a bar shadow on a screen by solar dish displacements. This system is independent respect to geographical location of the solar dish and periodical alignments such as daily or monthly regulations. Furthermore, the operation of the system is independent respect to the initial configuration and the start time situation.
