我们提出了两个紧凑的CMOS集成电路，用于计算直接聚焦到芯片上的图像的二维（2-D）局部运动方向。这些电路包括板载光感受器和焦平面运动处理。通过功能完整的14/spl times/13和12/spl times/13实现，每像素消耗低于50 /spl mu/W，我们得出结论，至少64/spl times/64的实际像素分辨率很容易实现。介绍了基本一维运动检测器的测量特征，并讨论了二维性能和二维运动矢量场的示例。作为该传感器的应用实例，表明该阵列可以直接计算二维运动矢量场的展开焦点。
We present two compact CMOS integrated circuits for computing the two-dimensional (2-D) local direction of motion of an image focused directly onto the chip. These circuits incorporate onboard photoreceptors and focal plane motion processing. With fully functional 14/spl times/13 and 12/spl times/13 implementations consuming less than 50 /spl mu/W per pixel, we conclude that practical pixel resolutions of at least 64/spl times/64 are easily achievable. Measurements characterizing the elementary one-dimensional motion detectors are presented along with a discussion of 2-D performance and example 2-D motion vector fields. As an example application of the sensor, it is shown that the array as fabricated can directly compute the focus of expansion of a 2-D motion vector field.
