中文摘要	This paper proposes a massively parallel keypoint detection and description(MP-KDD) algorithm for the vision chip with parallel array processors. The MP-KDD algorithm largely reduces the computational overhead by removing all floating-point and multiplication operations while preserving the currently popular SIFT and SURF algorithm essence. The MP-KDD algorithm can be directly and effectively mapped onto the pixel-parallel and row-parallel array processors of the vision chip. The vision chip architecture is also enhanced to realize direct memory access(DMA) and random access to array processors so that the MP-KDD algorithm can be executed more effectively. An FPGA-based vision chip prototype is implemented to test and evaluate our MP-KDD algorithm. Its image processing speed reaches 600–760 fps with high accuracy for complex vision applications, such as scene recognition.; This paper proposes a massively parallel keypoint detection and description(MP-KDD) algorithm for the vision chip with parallel array processors.
