Rehabilitation training system and method using virtual reality technology

Abstract

The invention discloses a rehabilitation training system and method using the virtual reality technology. The method includes the following stages: (1) skeleton joints of the human body are collected through a somatosensory device Kinect, and a skeleton system is generated; (2) a model is prepared, skeletons are bound, a database environment is constructed, the positions of the skeleton joints are obtained through machine learning of depth information and color information, modeling is achieved through a 3Dmax software tool, the human body skeleton IK / FK is built, and the joints of the model are bound in a one-to-one correspondence mode; (3) data of the Kinect are transmitted into a Unity3D through an interface function, and a scene model is driven to move; (4) a role is led in, and the environment is debugged; (5) the data are written in and read out, and visualization of the data is controlled. According to the rehabilitation training system and method, limitation of sensors is eliminated, and natural limb motion monitoring becomes possible; the somatosensory device Kinect is adopted, so that the system cost is reduced, and the complexity for wearing an input device in the training process is eliminated.

Description

technical field [0001] The invention relates to a rehabilitation training system and method, in particular to a rehabilitation training system and method using virtual reality technology with ingenious design and high intelligence. Background technique [0002] At present, in the domestic rehabilitation treatment, the main rehabilitation treatment method is mainly based on the therapist's manipulation, or assisting some simple training equipment, that is, through passive exercise, auxiliary exercise, active exercise and resistance exercise to achieve muscle recovery. purpose of motor function. This method has achieved very good rehabilitation effects, but at the same time, due to the limitations of the treatment methods, the patient is in a passive position. Moreover, in the training process, the movements are repeated, monotonous, and boring, and the patient is prone to boredom, which is not conducive to the continuation and deepening of the treatment. [0003] In order t...

Problems solved by technology

The wearing process is cumbersome, which affects the enthusiasm of users

[0008] (2) Patients need to perform movement correction before using the system, and the use process is cumbersome, which reduces the user's interest in training

[0009] (3) Wearable devices are usually expensive, which greatly increases the cost of the training system, which is not conducive to the purchase and use of patients at home

[0010] (4) The input interface is single, which is not conducive to the expansion of the system
