Vergence Micromovements and Depth Perception
A new approach in stereo vision is proposed in which 3D depth information is recovered using continuous vergence angle control with simultaneous local correspondence response. This technique relates elements with the same relative position in the left and right images for a continuous sequence of vergence angles. The approach considers the extremely fine vergence movements (micromovements) abou...
متن کاملDepth Cues and Perceived Audiovisual Synchrony of Biological Motion
BACKGROUND Due to their different propagation times, visual and auditory signals from external events arrive at the human sensory receptors with a disparate delay. This delay consistently varies with distance, but, despite such variability, most events are perceived as synchronic. There is, however, contradictory data and claims regarding the existence of compensatory mechanisms for distance in...
متن کاملVergence Control System for Stereo Depth Recovery
This paper describes a vergence control algorithm for a 3D stereo recovery system. This work has been developed within framework of the project ROBTET. This project has the purpose of designing a Teleoperated Robotic System for live power lines maintenance. The tasks involved suppose the automatic calculation of path for standard tasks, collision detection to avoid electrical shocks, force feed...
متن کاملMotion distorts perceived depth
Two important tasks that the visual system has to perform are determining the direction of motion and the spatial location of objects. It has recently been shown that the perceived location of an object moving in the frontal-plane is displaced along the direction of motion (e.g. Nature 397 (1999) 610; Vision Research 31 (1991) 1619). The aim of the present study is to examine the extent of this...
متن کاملPerceived motion in depth
We examine how various sources of information contribute to the percept of motion in depth. Subjects were presented with targets moving in depth, and were asked to judge their velocities and final positions. On each presentation, the target's position relative to the two eyes (target vergence), the size of the target's retinal image and the difference in this image's position relative to that o...
