摘要

我们演示了一种计算效率高的技术，用于使用角敏感像素来感知光流。角敏感像素由于其对角度的周期性响应而起空间Gabor滤波器的作用。测量正交滤波器相位响应的时间导数可以恢复物体运动的信息。这些传感器在没有镜头的情况下进行全局运动，或者在有镜头的情况下创建物体在环境光下运动的3D地图。

Phase-based 3D optical flow sensors for motion detection

We demonstrate a computationally efficient technique for sensing optical flow using angle sensitive pixels. Angle-sensitive pixels function as spatial Gabor filters as a result of their periodic response to angle. Measuring temporal derivatives in the phase response of quadrature filters recovers information about object motion. These sensors work without a lens for global motion, or, with a lens to create a 3D map of object motion under ambient light.
