Virtual-real fused hand function rehabilitation training system and method

Abstract

The invention discloses a virtual-real fused hand function rehabilitation training system and method. The rehabilitation training system comprises an image acquisition device and a background processing device, wherein the image acquisition device is used for carrying out real-time acquisition on multi-viewpoint hand images of users, then preprocessing the multi-viewpoint hand images, and sending the processed multi-viewpoint preprocessing images to the background processing device; and the background processing device is used for receiving the multi-viewpoint preprocessing images, carrying out three-dimensional modeling on the received multi-viewpoint preprocessing images so as to generate a three-dimensional hand model, then arranging the hand model in a virtual scene, and after the virtual scene produces a real-time feedback for the hand input, displaying the obtained output. By using the rehabilitation training system disclosed by the invention, the training on hand motion abilities is implemented through virtual-real interaction so as to speed up the rehabilitation of hand functions without increasing hand burden; the rehabilitation training system is simple in equipment structure and small in occupied space; the rehabilitation training method is easy to operate; users can carry out training by using the system and method disclosed by the invention without the guidance of professional doctors, and no damage to the users is caused; and the system has the advantages of good immersion sense and good instantaneity, and a good training effect can be achieved through virtual-real fusion.

Description

technical field [0001] The invention relates to a hand function rehabilitation training system combining virtual reality and reality, and belongs to the technical fields of computer vision and medical virtual reality. Background technique [0002] In addition to the necessary clinical treatment, some patients with injured limbs also need scientific rehabilitation training to make the injured part recover better. With the advancement of science and technology, medical virtual reality technology research has also made some progress. It can make up for the shortage of existing medical conditions and resources, avoid the possible dangers of real experiments or operations to patients, and improve the overall level of medical services. . At present, some research institutions are mainly focusing on the research of rehabilitation robot technology, which is based on equipment rehabilitation therapy, supplemented by virtual reality and robot technology, to train patients' limb funct...

Problems solved by technology

[0003] There are also some hand function training for patients by using data gloves. The device collects the patient's hand movements by setting data acquisition components in the gloves. Due to too many electronic components, the gloves are heavy and the patient is troublesome to wear. Moreover, heavy gloves may cause injury to patients, and the effect of rehabilitation training is not good
