Infrared temperature measurement fused with facial identification in an access control system
An example method of infrared access, comprising, receiving a plurality of visual images, receiving a plurality of infrared images, calibrating the plurality of visual images to the plurality of infrared images, determining an average temperature of the plurality of infrared images, determining an outlier temperature of an outlier infrared image of the plurality of infrared images and matching the outlier infrared image to a visual image.
1. A method of infrared access, comprising:
receiving a plurality of visual images;
receiving a plurality of infrared images;
calibrating the plurality of visual images to the plurality of infrared images, wherein the plurality of visual images and the plurality of infrared images are based on a distance below a predetermined threshold distance;
determining an average temperature of the plurality of infrared images;
determining an outlier temperature of an outlier infrared image of the plurality of infrared images; and
matching the outlier infrared image to a visual image of the plurality of visual images.
2. The method of infrared access of claim 1 wherein the average temperature is based on a moving average.
3. The method of infrared access of claim 1 wherein the outlier temperature is based on a threshold temperature above the average temperature.
4. The method of infrared access of claim 1 further comprising determining a facial signature of the plurality of visual images.
5. A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:
receiving a plurality of visual images;
receiving a plurality of infrared images;
calibrating the plurality of visual images to the plurality of infrared images, wherein the plurality of visual images and the plurality of infrared images are based on a distance below a predetermined threshold distance;
determining an average temperature of the plurality of infrared images;
determining an outlier temperature of an outlier infrared image of the plurality of infrared images; and
matching the outlier infrared image to a visual image of the plurality of visual images.
6. The non-transitory computer readable medium of claim 5 , wherein the average temperature is based on a moving average.
7. The non-transitory computer readable medium of claim 5 , wherein the outlier temperature is based on a threshold temperature above the average temperature.
8. The non-transitory computer readable medium of claim 5 , further comprising, determining a facial signature of the plurality of visual images.
