dc.description.abstract | A new real-time stereo system is presented based on a hardware implementation of an efficient Dynamic Programming algorithm. A simple state-machine calculates the cost-matrix along the diagonal of the 2-D disparity space for each epipolar pair of image scan-lines. Minimum transition costs are stored in embedded RAM and are used to backtrack disparities at clock rate. All calculations are within a pre-determined slice of the cost plane, representing the useful disparity range. The system is designed as a VHDL library component and is implemented as a SoC in a medium-capacity Field Programmable Gate Array chip. It can process stereo-pairs in full VGA resolution at a rate of 25 Mpixels/s and produces 8-bit dense disparity maps within a range of disparities up to 65 pixels. The design is evaluated comparing to ground truth and in terms of resource usage. It is also compared to a software implementation of the Dynamic Programming algorithm and to other FPGA-based stereo systems. | en |
