Perception of two-dimensional, simulated ego-motion trajectories from optic flow
A veridical percept of ego-motion is normally derived from a combination of visual, vestibular, and proprioceptive signals. A previous study showed that blindfolded subjects can accurately perceive passively travelled straight or curved trajectories provided that the orientation of the head remained constant along the trajectory. When they were turned (whole-body, head-fixed) relative to the tr...

متن کاملComputing Ego Velocity from Scene Flow estimation
This technical report describes a new approach that estimates the velocity of the ego vehicle using a monocular setup to compute an approximation of the scene flow.
متن کاملAn Efficient Linear Method for the Estimation of Ego-Motion from Optical Flow
Approaches to visual navigation, e.g. used in robotics, require computationally efficient, numerically stable, and robust methods for the estimation of ego-motion. One of the main problems for egomotion estimation is the segregation of the translational and rotational component of ego-motion in order to utilize the translation component, e.g. for computing spatial navigation direction. Most of ...
متن کاملA simplified linear optic flow-motion algorithm
The purpose of the article is to establish the relationship between rigid body motion and the optic flow image and solve motion parameters from optic flow image points. A basic equation relating optic flow image points to rigid body motion which involves only the instantaneous rotation and translation velocities without depths is established. A linear algorithm is developed to determine the mod...
