ABSTRACT:
A passive method and system for mitigating image distortion due to optical turbulence in a surveillance system is disclosed. An array of cameras forming a stereo camera array is employed to view a distant object or objects and background to obtain multi-hyperstereo image data, and the latter data are processed in accordance with statistical comparison and integration techniques to mitigate the effects of optical turbulence in near real-time. Further features of the invention involve comparison of multi-hyperstereo images with uncorrelated optical turbulence distortions, the reconstruction of the distant object and background using segmenting and time-integration techniques, and the execution of time-averaging and correlation algorithms.
