A fast-extraction and real-time processing method for polarization images based on light field is put forward.With the multi-core DSP TMS320C6678 as the core processor, a series of continuous process including the collection of light field images as well as the extraction and processing of polarization images has been realized. Detailed introduction of system hardware and software design is given. The proposed system uses DSP + FPGA, of which the FPGA module implements the camera-link interface and image ac...
