摘要：

We estimate the motion of a rigid body from two noisy 2-D perspective projections using the least squares method and the algebra of Tsai and Huang. The accuracy of the estimated motion parameters is influenced by the position of the features of the object used in the calculation. We derive four test variables that indicate how the accuracy is influenced and use them for discarding inaccurate estimates. Monte Carlo tests demonstrate the obtained accuracy.
