Compressed sensing based object imaging system and imaging method therefor

Abstract

A compressed sensing based object imaging system and an imaging method thereof. The object imaging system comprises a light source generation unit (), a filter unit (), an image generation unit (), an image acquisition unit (), and an image reconstruction unit (). The light source generation unit () generates experimental laser; the filter unit () filters high frequency scattered light and forms parallel light; the image generation unit () generates an experimental image in which an object image () and a specific measurement matrix () are superimposed; the image acquisition unit () performs compression sampling on the generated experimental image; and the image reconstruction unit () reconstructs sampling data to restore the object image (). The imaging method comprises: establishing a sample database comprising the specific target object image (); training sample images to obtain the specific measurement matrix (); and simultaneously completing image sampling, image compression and image recognition in an all-optical system. The system and the method can greatly reduce the data volume recorded in image recognition and image matching, thus improving the real-time performance of the system, and providing a possibility of concurrent processing by machine vision and artificial intelligence.
