Motion Detection of Bird Based on Optical Radar

The motion detection of birds around airports is a fundamental assignment for preventing bird strikes. With the growth of image processing algorithms, optical radar can achieve the motion detection of birds like electromagnetic radar. Unfortunately, with the restriction of the optical radar position in airports, the change of illumination, and the influence of bad weather, the image of birds captured by optical radar in airports is unclear and lose the detail of color and texture. In this paper, multiple methods, such as optical flow, background subtraction, and frame difference, are proposed and modified to implement the motion detection of birds for bird control in airports. We compare the performance and robustness of these algorithms in the motion detection of birds and illustrate the difference between these approaches.
