System, method, and apparatus for temperature asymmetry measurement of body parts

A method for detection of arthritis based on temperature asymmetry estimation in joints, the method comprising:

• recording, using an optical camera and a thermal camera, an optical image and a thermogram corresponding to a first joint of the joints and an optical image and a thermogram corresponding to a second joint of the joints, the second joint being contralateral to the first joint;
• receiving, by a processing unit, the optical image and the thermogram corresponding to the first joint and the optical image and the thermogram corresponding to the second joint;
• estimating, by the processing unit, a recorded image displacement based on the thermogram and the optical image corresponding to the first joint, estimating the recorded image displacement corresponding to the first joint including localizing a template of the first joint by locating corresponding pairs of keypoints in the optical image and in the thermogram and calculating a nonconformity error between the corresponding pairs of keypoints in the optical image and in the thermogram, and estimating the recorded image displacement corresponding to the first joint further including fine tuning by fitting a shape of the first joint on the thermogram and the optical image;
• estimating a recorded image displacement based on the thermogram and the optical image corresponding to the second joint, estimating the recorded image displacement corresponding to the second joint including localizing a reference template of the second joint by locating corresponding pairs of reference keypoints in the optical image and in the thermogram and calculating a nonconformity error between the corresponding pairs of reference keypoints in the optical image and in the thermogram, and estimating the recorded image displacement corresponding to the second joint further including fine tuning by fitting a reference shape of the second joint on the thermogram and the optical image;
• and
• determining, by the processing unit, that arthritis of the first joint has occurred by comparing the thermogram corresponding to the first joint to the thermogram corresponding to the second joint based on the recorded image displacement corresponding to the first joint and the recorded image displacement corresponding to the second joint.
