沿着移动系统的视网膜上的一组预定方向测量视网膜运动可以产生全局模式。由于这些图案的形状和位置完全依赖于三维(3D)运动，因此3D运动和场景结构对图像运动的影响可以全局分离。这些图案是建立在容易得出的图像测量基础上的，这些图像测量只依赖于图像运动的符号，不需要关于光流的信息。这里提出的计算理论解释了如何通过定位这些模式来估计系统的自运动。
Measurements of retinal motion along a set of predetermined orientations on the retina of a moving system give rise to global patterns. Because the form and location of these patterns depend purely on three-dimensional (3D) motion, the effects of 3D motion and scene structure on image motion can be globally separated. The patterns are founded on easily derivable image measurements that depend only on the sign of image motion and do not require information about optical flow. The computational theory presented here explains how the self-motion of a system can be estimated by locating these patterns.
