摘要

采用硅视网膜和FPGA电路构成了一种新型的机器人视觉系统。硅视网膜已经发展到模仿平行电路结构的脊椎动物视网膜。这里使用的硅视网膜是一个模拟CMOS超大规模集成电路,可以实时对图像执行类似拉普拉斯-高斯(/spl nabla//sup 2/G)的滤波和帧减法。FPGA电路控制硅视网膜,并根据系统的应用执行图像处理。该机器人视觉系统具有硬件紧凑、功耗低的特点,能够在自然光照下实现实时、鲁棒的计算。

Silicon retina system applicable to robot vision
A novel robot vision system was configured using a silicon retina and FPGA circuit. Silicon retina has been developed to mimic the parallel circuit structure of the vertebrate retina. The silicon retina used here is an analog CMOS very largescale integrated circuit which executes Laplacian-Gaussian (/spl nabla//sup 2/G)-like filtering and frame subtraction on the image in real time. FPGA circuit controls a silicon retina and executes image processing depending on application of the system. This robot vision system can achieve real time and robust computations under natural illumination with a compact hardware and a low power consumption.
