我们利用“运动形状问题”的最优解和在纯光学基础上估计自运动的相关问题，推导出在存在运动视差场扰动的情况下光流信息量极限的实用经验法则。通过计算机仿真，对计算结果进行了说明和验证。结果允许估计作为数据采样精度和视场宽度的函数的深度和运动估计的精度，以及运动的旋转和平移分量之间的相互作用的估计。
We employ optimal solution to both the "shape from motion problem" and the related problem of the estimation of self-movement on a purely optical basis to deduce practical rules of thumb for the limits of the optic flow information content in the presence of perturbation of the motion parallax field. The results are illustrated and verified by means of a computer simulation. The results allow estimates of the accuracy of depth and egomotion estimates as a function of the accuracy of data sampling and the width of field of view, as well as estimates of the interaction between rotational and translational components of the movement.
