System and method for detecting an object in the path of a vehicle
First Claim
1. A system for detecting an object in the path of a vehicle, the system comprising:
- two correlation-based motion sensor modules, each of the correlation-based motion sensor modules comprising;
a sensor array configured to generate frames of image information;
optics configured to focus light onto the sensor array;
a correlation engine configured to correlate frames of image information to generate an indication of the relative displacement of an object; and
a detection engine in signal communication with the correlation-based motion sensor modules and configured to use the indications of relative displacement from the correlation-based motion sensor modules to detect an object in the path of a vehicle.

Abstract
Correlation-based motion sensor modules similar to those used in optical mice are applied to systems and methods for detecting an object in the path of a vehicle. A system for detecting an object in the path of a vehicle includes at least two correlation-based motion sensor modules and a detection engine. Each of the correlation-based motion sensor modules includes a sensor array, optics, and a correlation engine. The optics focus light onto the sensor array, the sensor array generates frames of image information, and the correlation engine correlates the frames of image information to generate an indication of the relative displacement of an object. The detection engine uses the indications of relative displacement from the correlation-based motion sensor modules to detect an object in the path of a vehicle.

10. A method for detecting an object in the path of a vehicle, the method comprising:
-
establishing first and second fields-of-view within which frames of image information can be captured, wherein the fields-of-view are oriented to overlap in the path of the vehicle; capturing frames of image information from within the first and second fields-of-view; using the frames of image information captured from within the first field-of-view to generate an indication of relative displacement of an object within the first field-of-view; using the frames of image information captured from within the second field-of-view to generate an indication of relative displacement of the object within the second field-of-view; and using the indications of relative displacement to detect an object in the path of the vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16)
