Problems solved by technology

Finding structure from motion presents a similar problem as finding structure from stereo vision.
These systems are capable of producing dense depth map information but at considerable computational expense.
Depth maps may also lack the full spatial resolution of the original gray scale images.
However, due to the computational cost, it is often inhibitive to compute a depth map at such a large resolution.

Embodiment Construction

[0023]Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.

[0024]Referring now to the drawings, reference is now made to FIGS. 1 and 2 which illustrate a system 16 including a camera or image sensor 12 mountable in a vehicle 18, according to an aspect of the present invention. Image sensor 12, imaging a field of view in the forward direction typically delivers images in real time and the images may be captured in a time series of image frames 15. An image processor 14 may be used to process image frames 15 simultaneously and / or in parallel to serve a number of driver assistance systems. Image sensor 12 is typically monochrome or black-white, i.e. without color separation. By way of example in FIG. 2, image frames 15 may be used to...

Abstract

Detection of three dimensional obstacles using a system mountable in a host vehicle including a camera connectible to a processor. Multiple image frames are captured in the field of view of the camera. In the image frames, an imaged feature is detected of an object in the environment of the vehicle. The image frames are portioned locally around the imaged feature to produce imaged portions of the image frames including the imaged feature. The image frames are processed to compute a depth map locally around the detected imaged feature in the image portions. Responsive to the depth map, it is determined if the object is an obstacle to the motion of the vehicle.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation in part application of U.S. patent application Ser. No. 13 / 237,163 filed on 20 Sep. 2011. The present application claims priority from U.S. provisional patent application 61 / 765,748 filed on 17 Feb. 2013 by the same inventors, the disclosures of which are incorporated by reference as if entirely set fort herein.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to detection of three-dimensional structures from two-dimensional images and particularly related to application in driver assistance systems[0004]2. Description of Related Art[0005]Structure-from-Motion (SfM) refers to methods for recovering three-dimensional information of a scene that has been projected onto the back focal plane of a camera. The structural information derived from a SfM algorithm may take the form of a set of projection matrices, one projection matrix per image frame, representing the relationship bet...
