Abstract:
A polarization imaging system for generating a super resolution image is disclosed in the present invention. The polarization imaging system consists of multiple functional elements for the generation of the super resolution image including a camera device, a polarization analysis module, a weight module, a fusion module and an output module. The lens of the imaging system captures light coming from a subject which is detected and acted upon by a polarization sensor. The polarization sensor generates multiple low resolution images and calculates degree of linear polarization and angle of polarization of the light rays based on which a guided mask is generated. The system employs an algorithm to combine the one or more low resolution images to produce a final super resolution image as the output.
