Visibility Analysis Using Running Maximum Elevation Angle Interpolation

A new algorithm for point to region visibility analysis is proposed. Only the visibility of points located on the front boundary needs to be analyzed by point to point visibility analysis. As to the interior points, according to the space continuum, their visibility can be judged by the frontal points using running maximum elevation angle interpolation. Experimental results demonstrate this algorithm meets the requirement of real-time and has high stability and high accuracy.
