Path planning of UAV between two random points without threats

For the path planning of unmanned aerial vehicles (UAV) without threats, a simple and effective method, path planning based on geometric method, is proposed. After showing the basis of the geometric method, the primary ideas and realization steps of path planning based on geometric method is studied. Then, an example is given and the results demonstrate the proposed method is effective. Finally, the advantages and disadvantages of the geometric method are summarized.
