According to growth background and physiological factors, gait of each person is different, and so is distribution of foot pressure. However, congenital conditions or wrong walking way and even selecting unsuitable shoes cause gait abnormality and foot pressure distributes unevenly. Above-mentioned minor effects influence the lower limbs become painful and severe effects influence the waist, spine, and even discomfort the whole body. This study applies image processing to analyze gait and foot pressure and establish real-time evaluation system for human gait. The system captures images of walking when users walking on the platform and then employs the related parameters of image processing analysis for gait, such as distribution graph of foot pressure, critical knee joint bending angle of critical gait stage, and so on. Furthermore, the system displays the analysis result on the output image immediately so that user enables to observe their own gait instantly. After testing, the system accesses the results from user which provide to therapists and other professionals for evaluating recovery conditions before and after rehabilitation.
