Quick screening method for assessing diabetic foot syndrome

A quick screening method for assessing diabetic foot syndrome for a person, comprising:

• positioning both feet of the person onto a testing plate that blocks visible light and permits passage of near infrared (NIR);
• using a multi-spectral camera device to simultaneously capture a thermal image and an NIR image of soles of the feet of the person from a side of the testing plate that is opposite to the feet of the person;
• performing image processing to align the thermal image with the NIR image and overlay the thermal image and the NIR image, thereby obtaining an assessment image of the feet;
• determining, based on the assessment image, whether a temperature difference between a predetermined portion of one of the feet and a corresponding portion of the other one of the feet exceeds 2.2° C.;
• and
• reporting a potential case of diabetic foot syndrome in response to determining that the temperature difference exceeds 2.2° C.
