CAMERA-BASED CYCLE PEDALING LOWER LIMB ALIGNMENT EVALUATION SYSTEM AND METHOD

摘要

The present invention relates to a camera-based cycle pedaling lower limb alignment evaluation system and a method thereof. More particularly, the present invention relates to a camera-based cycle pedaling lower alignment evaluation system which can quantitatively measure the trajectory of a vertical direction, the inner and outer part of knee joints which closely relates to the vertical alignment of limbs through a front photography in pedaling. In the present invention relating to a camera-based cycle pedaling lower limb alignment evaluation system using image data, a reflection mark for photographing the change of the trajectory of the knee joints in the frontal plane with respect to the vertical alignment of the lower limb in the pedaling.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Front camera; (BB) Trajectory of frontal plane; (CC) Measure the pattern of the knee joint trajectory; (DD) Lateral camera; (EE) Angle of sagittal plane; (FF) Calculate the angle of hip, knee joint, and ankle joint; (S110) Set an image; (S112) Set the camera(front side, lateral side); (S114) Set the region of interest(ROI); (S120) Obtain a marker trajectory; (S122) Obtain the image; (S124) Recognize a marker
