Design And Implementation Of A Gait Analysis System Based On Kinect Depth Information

Current era,the rapid development of computers has prompted the rapid advance of all walks of life.Today,the combination of the computer field and the medical field has become the mainstream of the times.Nowadays,the research of human motion analysis has been increasingly popular.The gait analysis system has been developed to understand the condition of the stroke patients.The gait analysis system can be used to check the rehabilitation of stroke patients,formulate effective medical plans,Has an important guiding role.In the design and implementation of the gait analysis system,the Kinect camera introduced by Microsoft,because the depth information is more stable than the commonly used color map in the image information processing,the depth value is only in the distance change and change,not work by color or light.In the whole system,the research background and significance of system design and implementation are analyzed,and the application field and some technical limitations of the current gait analysis system are described.Finally,the key techniques of the system are studied.The key technologies of the whole system implementation are discussed.The target detection and the recognition of the joints are discussed.Then,the deficiency of the current gait analysis system is analyzed from the demand analysis and the main application of the system is analyzed.The whole system is divided into data acquisition module,data processing module and gait parameter extraction module,which is the final gait.The whole system is divided into data acquisition module,data processing module and gait parameter extraction module.Analysis system to achieve the entire test and lay the guarantee.Through the design and implementation of the gait analysis system,the patient's gait video is saved and analyzed,and the saved video can be analyzed,so that the doctor can directly watch the patient's knuckle points are positioned gait walking video to help doctors directly from the visual On the walking condition of patients to determine the final data through the calculation of gait parameters to analyze the patient's rehabilitation.
