Abstract
Systems and methods for estimating distances to objects or features are described. The distance estimation tracks features across images captured from a single camera mounted to an automobile and determines features that are off-ground. Features are tracked based on a ground motion estimate and respective motion of the features tracked across two or more successive images. For each off-ground feature a distance to the camera is calculated based on motion of the feature in the images captured by the camera projected to a ground-plane and the ground motion estimate.
