Patent attributes
A video-based monitoring and image post-processing system may include a plenoptic camera that has multiple mirrors in its field of view. The plenoptic camera may capture four-dimensional light-field information for multiple images of its field of view and may embed that information in image data sent to a local or backend server for post-processing. An image processing application on the server may extract image data for pixels that collectively represent one of the mirrors, and apply a focusing operation on the extracted image data to generate a video stream of a virtual camera represented by the mirror, dependent on the image information and the distance between the mirror and the camera. The application may correct distortions due to the curvature of the mirror. The system may provide video monitoring in areas without a single line of sight without the need for a large number of expensive cameras.
