....in [4] with real data collected from the vehicle. A recent technical development related to the perception of the UGV s environment is the concept of iso distortion surfaces, a framework for studying the relationship between the computation of 3D motion and depth from a sequence of images [3]. The underlying conceptual theme is that motion errors (e.g. errors between retinal motion and perceived 3D motion) affect depth estimates systematically. The understanding of the geometry of this distortion of depth is essential for understanding the interplay between 3D motion and shape ....

....of the transformation, we obtain the restriction of the shape distortion to the XZ plane (the fixation plane) Note that this restriction is only meaningful when the shape distortion preserves the fixation plane, i.e. when a The term distortion factor was first used in this context by L. Cheong [13], who studied the distortion of shape from motion by examining iso distortion contours , i.e. loci of points whose depth is distorted by the same multiplicative factor. 4 it maps the fixation plane in the true configuration (Y = 0) to the fixation plane in the apparent configuration (Y 0 = ....

....transformation of space, relating points to the distorted reconstructions of their image correspondences. In Section 1, we showed that the shape distortion transformation for the example of a calibrated, fixating, stereo rig was quadratic. A similar relationship was investigated by Cheong et al. [13, 14] for the case of calibrated cameras under the infinitesimal motion assumption. In Section 3 we derived the shape distortion transformation for the general case of uncalibrated, and arbitrarily positioned and oriented, cameras, and showed that the full range of distortions for a stereo rig, due to ....
