摘要

对于一个运动的观察者来说，根据环境中的结构来预测运动过程是很重要的。移动的观察者可以获得的光流包含了视觉动觉的强大信息。一般来说，光流由可分离的平移和旋转分量组成。这里检查的信息完全包含在平移分量及其时间导数中。观测曲线路径是由光学速度场和加速度场的平移分量的不同方向决定的。在光流中指定了障碍物及其与曲线运动观察者的时间间隔，以及碰撞角度。

Information in optical flows induced by curved paths of observation.

For a moving observer it is essential to foresee the locomotor course with respect to structures in the environment. Optical flows that are available to a moving observer contain powerful information for visual kinesthesis. In general, optical flows consist of separable translational and rotational components. The information examined here is contained completely in the translational component and its time derivatives. Curved paths of observation are specified by different orientations of the translational components of optical velocity and acceleration fields. Obstacles and their temporal separation from a curvilinearly moving observer are specified in the optical flow, as is the angle of collision.
