Fusion of far infrared and visible images in enhanced obstacle detection in automotive applications
First Claim
1. A system comprising:
- a first camera that has a first field of view, the first camera configured to travel with a vehicle,a second camera that has a second field of view, the second camera configured to travel with a vehicle, the first field of view being narrower than the second field of view, anda processor that is configured to detect an object at a first time using a first frame of first image frames acquired via the first camera,the processor is configured to track the object using the first image frames,the processor is configured to project, at a second time, a location of the object in a second frame of the first image frames onto a location in a first frame of second image frames acquired via the second camera, and detect the object in the first frame of the second image frames using the projected location of the object.

Abstract
A computerized system mountable on a vehicle operable to detect an object by processing first image frames from a first camera and second image frames from a second camera. A first range is determined to said detected object using the first image frames. An image location is projected of the detected object in the first image frames onto an image location in the second image frames. A second range is determined to the detected object based on both the first and second image frames. The detected object is tracked in both the first and second image frames When the detected object leaves a field of view of the first camera, a third range is determined responsive to the second range and the second image frames.

23. A non-transitory computer readable medium storing a program causing a computer to execute a processing method for use in a system, the system comprising a first camera configured to travel with a vehicle and a second camera configured to travel with a vehicle, the first camera having a first field of view and the second camera having a second field of view, the first field of view being narrower than the second field of view, the method comprising:
-
detecting an object at a first time using a first frame of first image frames acquired via the first camera, tracking the object using the first image frames, projecting, at a second time, a location of the object in a second frame of the first image frames onto a location in a first frame of second image frames acquired via the second camera, and detecting the object in the first frame of the second image frames using the projected location of the object.
