Robust structure from motion using motion parallax
We present an efficient and geometrically intuitive algorithm to reliably interpret the image velocities of moving objects in 3D. It is well known that under weak perspective the image motion of points on a plane can be characterised by an affine transformation. We show that the relative image motion of a nearby noncoplanar point and its projection on the plane is equivalent to motion parallax ...
متن کاملMotion parallax in electric sensing.
A crucial step in forming spatial representations of the environment involves the estimation of relative distance. Active sampling through specific movements is considered essential for optimizing the sensory flow that enables the extraction of distance cues. However, in electric sensing, direct evidence for the generation and exploitation of sensory flow is lacking. Weakly electric fish rely o...
متن کاملMotion parallax and absolute distance.
The accuracy of absolute distance estimation based on monocular motion parallax was determined both before and after specific training. With the usual distance information eliminated, subjects either held their heads stationary, or rhythmically rotated their heads from side to side, while judging the distance of stimuli placed 4-15 ft. away. Before training, head movement produced more accurate...
متن کاملTowards qualitative vision: motion parallax
A robot vehicle moving under visual guidance needs to compute approximate geometry of obstacles in its environment. It is unreasonable to assume that egomotion is known to the sort of precision that is available for a camera mounted on a high quality robot arm. Generally a nominal estimate for egomotion is available. One possibility is to refine this estimate using optic flow data (Harris, 1987...
متن کاملAnaglyph Caustics with Motion Parallax
In this paper we present a method to model and simulate a lens such that its caustic reveals a stereoscopic 3D image when viewed through anaglyph glasses. By interpreting lens dispersion as stereoscopic disparity, our method optimizes the shape and arrangement of prisms constituting the lens, such that the resulting anaglyph caustic corresponds to a given input image defined by intensities and ...
