In the process of walking,diverse differences of lower limbs match different gait,while gait presents the body's posture transformation,which has the characteristics of periodicity and individual difference,and is an important biomechanical and kinematics information.At present,in the field of computer-aided diagnosis,rehabilitation medical treatment and evaluation,the application value of gait analysis has become increasingly prominent.Therefore,through the collection of gait parameter data of different lower extremities,a diagnosis method based on human gait characteristics is proposed,which provides a theoretical basis for the diagnosis and corrective suggestions of people with different levels of lower limbs.First of all,by manually simulating the unequal length of the lower limbs,I use the laboratory equipment to collect the kinematics and biomechanical characteristics of diverse lower limbs differences,to obtain the original gait dataset.The dataset is then cleaned for normalization and homogenization.Finally,the standard raw dataset is obtained by using the interpolation method.Secondly,this paper designs an algorithm of feature selection,and uses this algorithm to select the characteristics of the final gait dataset obtained after perfection.The algorithm is to take the standard deviation of Euclidean distance between each category as the reference standard,and through the iterative method,the feature is selected and the eigenvector is obtained without human intervention.Finally,I collected and selected the gait data of patients with unequal lower extremities,and calculated the similarity,and obtained the degree of unequal lower limbs based on gait characteristics,and gave some suggestions for correction.Based on the different degrees of lower limbs,the numerical changes of different characteristic parameters presented by them are visualized and analyzed,and the changes of biomechanical and kinematics parameters of human body are obtained and analyzed.Based on the study of gait data acquisition,processing and analysis,as well as feature selection,this paper provides a theoretical basis for auxiliary diagnosis,and provides corrective suggestions and subsequent gait evaluation,and takes into account the differences of unequal gait characteristics of lower limbs at different degrees.
