Research Of Motor Impairment Assessment Training System Based On Kinect

In recent years,the number of people with motor dysfunction has increased significantly due to traffic accidents and various diseases.After these specific groups are discharged from the hospital,they must undergo long-term rehabilitation training.At present,the most commonly used rehabilitation treatment method is to perform a large number of repeated one-to-one limb training under the guidance of a rehabilitation doctor.With the gradual increase of patients,traditional rehabilitation training methods have been unable to meet the needs of patients.First of all,there are few professional rehabilitation doctors,and the cost of treatment is high,and most families can't afford the financial pressure.Secondly,the training process is boring,and it is difficult to visualize the data in rehabilitation training.How to provide an effective and convenient way of rehabilitation assessment training has become an important subject of current research.This article addresses the above problems in rehabilitation assessment training,Based on Kinect body sensing technology and motion recognition algorithm,Combined with Unity3 D three-dimensional animation technology,Designed to assist the movement disorders rehabilitation assessment system.The main research contents are as follows:First,Based on in-depth analysis and research of virtual reality technology and human-computer interaction technology,Select Kinect somatosensory technology and set up a development environment.Real-time data information on the spatial position of joint points of a moving human body was obtained through this system,And complete the development of bone tracking programs.Calculate and extract joint point angle feature points and instantaneous velocity feature points on the acquired data information sequence,The Holt exponential smoothing method was used to filter and denoise the feature point data sequence.Through experimental verification,Holt exponential smoothing method has good data smoothing effect.Secondly,through in-depth research on 3D modeling in virtual reality technology,Create 3D virtual character models.Research and analysis on traditional dynamic time warping algorithms.And improve the singularity problem and time complexity problem,An adaptive weighted dynamic time warping algorithm based on PLA method is proposed.After experimental verification,the improved algorithm can properly solve the singularity problem and reduce the time complexity of the algorithm.Finally,Through detailed investigation and research on user demand functions,Determined the design goals of the system,Combined with Unity3 D technology to design and develop an assisted rehabilitation system with both rehabilitation training and assessment functions,It also elaborates on the function design and implementation of each part of the system.In order to improve the efficiency of dyskinesia assessment and training,It provides a reference solution to the problem of boring rehabilitation training and difficult to quantify the effect.
