APPARATUS AND METHOD FOR THERMAL SIDE DETECTION IN A VEHICLE
First Claim
1. A detecting device for a vehicle, the detecting device comprising:
- a first infrared detector configured to repeatedly measure a temperature of a first target area by receiving infrared radiation of the first target area, the first infrared detector being configured to provide a plurality of first signals each corresponding to a measured temperature of the first target area over a sampling period;
a second infrared detector configured to repeatedly measure a temperature of a second target area by receiving infrared radiation of the second target area, the second infrared detector being configured to provide a plurality of second signals each corresponding to a measured temperature of the second target area over the sampling period, the second target area being different from the first target area; and
a controller configured to receive and store the plurality of first signals and the plurality of second signals in a storage medium, wherein the controller repeatedly compares a plurality of correlation values to a predetermined tolerance range above a minimum threshold value to determine if an object is moving in either the first target area or the second target area and towards the detecting device, wherein the plurality of correlation values are determined by repeatedly comparing a plurality of time delayed signals of the second plurality of signals to a real time signal of the plurality of first signals.
