This paper describes the results of some experiments on estimating the 3-D motion parameters of a rigid body from two consecutive TV images, and discusses several factors which affect the accuracy of the results. These factors include the sizes of the motion parameters themselves, the accuracy of the raw data, and the number of point correspondences. In addition, we address two related topics: determining corner positions to subpixel accuracy and matching point patterns with different scales.
