A technique is described of predicting the uncertainty of trifocal transfer. The technique is an improvement upon a method for determining the perspective projection of a spatial point in three image frames, given the geometric constraint of trilinearity as defined by a set of trilinear equations, where trifocal transfer is used to predict a corresponding point in the third frame from a trifocal tensor and points in the first two frames. The improvement comprises the step of predicting the uncertainty of trifocal transfer in the third image subject to the uncertainties affecting corresponding points in the first two images of a rigid scene under perspective projection using the trifocal tensor. <IMAGE> |
