This paper presents an asynchronous DFE (A-DFE) method which uses simple dual generic cameras with a dedicated designed hardware architecture for the camera mismatch, which significantly improves the upper limit of the measured velocity. Based on this method, we build up a pseudo-high-speed camera (PHSC) system for motion estimation on FPGA. The system achieves the shortest time interval of 1.06 ns, and the energy efficiency with 3.23 nJ/pixel on the low-cost XILINX Spartan-7 platform.
