Abstract:
Determining three-dimensional structure in a road environment using a system mountable in a host vehicle including a camera connectable to a processor. Multiple image frames are captured in the field of view of the camera. In the image frames, a line is selected below which the road is imaged. The line separates between upper images essentially excluding images of the road and lower images essentially including images of the road. One or more of the lower images is warped, according to a road homography to produce at least one warped lower image. The three-dimensional structure may be provided from motion of a matching feature within the upper images or from motion of a matching feature within at least one of the lower images and at least one warped lower image.

Claim (Index 19):
A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of an electronic device, cause the electronic device to:\n receive a previous image of a road environment and a current image of the road environment; identify a road of the road environment in the previous image; identify a first portion of the previous image including the road of the road environment and a second portion of the previous image excluding the road of the road environment; warping the first portion of the previous image according to a homography of the road and ego-motion of a host vehicle to provide a warped portion of the previous image, wherein the ego-motion is based on at least one of speed, inertia, and steering angle of the host vehicle; matching a first point between the first portion of the previous image and a second point of the current image to provide a first matching; matching the first point between the warped portion of the previous image and the first portion of the current image to provide a second matching; and providing a three-dimensional structure based on at least one of the first matching or the second matching.
