US 12,770,282 B2 · Joint angle determination under limited visibility

Abstract

Provided herein are methods and systems for determining joint information, such as joint angle and range of movement, quickly and accurately without using cumbersome, specialized equipment even when visibility to the joint may be limited. Such methods and systems may be achieved by using computationally efficient approaches that are accurate and robust enough to handle noises and occlusions. The methods and systems provided herein may provide quick, low-cost, on-demand approaches to obtain information about the joint health of a patient. The joint angle information may facilitate diagnosis, treatment, prognosis, and/or rehabilitation of the patient from a joint injury, pain, or discomfort by providing quick, actionable information to the healthcare provider.

Dependent claims

A computer-implemented method for determining an angle in an object of interest, the method comprising:

(a) obtaining an image or a video of the object of interest;
(b) generating a plurality of key point heatmaps and a plurality of segment heatmaps from the image or the video;
(c) blending at least one of the plurality of key point heatmaps with at least one of the plurality of segment heatmaps to generate at least one blended heatmap;
(d) extracting features from the at least one blended heatmap, wherein the extracted features comprise extracted segments, and wherein the extracted segments are extracted using a line detection method;
and
(e) determining the angle in the object of interest by calculating an angle formed by the extracted features, wherein the angle is formed by the extracted segments.
