我们描述了一种用于移动机器人和机器视觉应用的CMOS中央凹图像传感器的设计与实现。该传感器受生物学启发,可执行从笛卡尔坐标到对数极坐标的空间图像变换。与传统方法不同,由于使用了标准的1.2μm专用集成电路互补金属氧化物半导体(ASIC CMOS)工艺,该传感器具有高度集成、功耗极低以及易于制造的优点。当与个人计算机连接时,该原型成像器以每秒28帧的速度运行。
We describe the design and implementation of a CMOS foveated image sensor for use in mobile robotic and machine vision applications. The sensor is biologically motivated and performs a spatial image transformation from Cartesian to log-polar coordinates. As opposed to traditional approaches, the sensor benefits from a high degree of integration, minimal power consumption and ease of manufacture due to the use of a standard 1.2 /spl mu/m ASIC CMOS process. The prototype imager operates at 28 frames/sec when interfaced to a PC.
