Fusion of far infrared and visible images in enhanced obstacle detection in automotive applications
First Claim
1. A method of determining a danger of collision between a vehicle and an object, comprising:
- acquiring by a first camera mounted on the vehicle, a plurality of first camera image frames acquired at different times;
acquiring by a second camera, mounted on the vehicle, a second camera image frame;
detecting an object, possibly in a course of collision with the vehicle, in one or more of the first camera image frames;
locating the detected object in the second camera image frame;
determining a distance between the vehicle and the object responsive to the location of the detected object in both the first camera and second camera image frames; and
determining if there is a danger of collision between the vehicle and the object at least partially responsive to the determined distance.

Abstract
A method in computerized system mounted on a vehicle including a cabin and an engine. The system including a visible (VIS) camera sensitive to visible light, the VIS camera mounted inside the cabin, wherein the VIS camera acquires consecutively in real time multiple image frames including VIS images of an object within a field of view of the VIS camera and in the environment of the vehicle. The system also including a FIR camera mounted on the vehicle in front of the engine, wherein the FIR camera acquires consecutively in real time multiple FIR image frames including FIR images of the object within a field of view of the FIR camera and in the environment of the vehicle. The FIR images and VIS images are processed simultaneously, thereby producing a detected object when the object is present in the environment.

26. A vehicle warning system mounted on a vehicle including a cabin and an engine, the system including:
-
a first camera mounted on the vehicle, which acquires consecutively in real time a plurality of first camera image frames; a second camera mounted on the vehicle, which acquires second camera image frames; and a processor configured to detect an object in one or more first camera image frames, to locate the detected object in the second camera image frame, to determine the distance between the vehicle and the object responsive to the location of the detected object in both the first and second camera image frame and to determine if there is a danger of a collision between the vehicle and the object responsive to the determined distance. - View Dependent Claims (27, 28, 29, 30, 31)
