Embodiment Construction

[0047] The present invention captures the movement of the patient through the depth camera, provides instructions and feedback on the assessment items through the virtual reality scene, and analyzes and quantitatively evaluates the patient's movement ability through the image processing algorithm. The whole process does not require other personnel to participate, and the patient follows the instructions It can be completed, saves time and labor, saves labor, saves cost, and can be used in occasions such as families.

[0048]It needs to be clarified that the "depth camera" is a camera capable of collecting both RGB images and depth information of each pixel, also known as an RGBD camera, including but not limited to based on the principle of structured light, TOF principle or dual Depth camera based on the principle of eye imaging. The “virtual reality technology” mentioned in this disclosure uses a computer to generate a simulated environment, and processes and responds to the...

Abstract

The invention provides a rehabilitation function assessment device and method based on a depth camera and a virtual reality technology. The device includes a depth camera, a data processing module anda display module. Depth image information of a joint motion acquired by the depth camera is transmitted to the data processing module for the following processing: joint point three-dimensional coordinates are extracted, joint angle related parameters are calculated according to the joint point three-dimensional coordinates, and joint movement capability evaluation is performed by combination with the joint angle related parameters; and the data processing module further includes a virtual reality training sub-module which is used to convert a continuously-acquired depth images into virtual model images and displaying the virtual model images in the display module. The rehabilitation function assessment method is further provided. According to the rehabilitation function assessment deviceand method, the quantification and automation of the rehabilitation function assessment are achieved, the entire process does not require the participation of other people, and a patient can completethe assessment according to instructions, and the habilitation function assessment device and method save time and labor, reduces costs and can be used in homes and other occasions.

Description

technical field [0001] The present disclosure relates to the technical field of rehabilitation assessment, in particular to a rehabilitation function assessment device and method based on a depth camera and virtual reality technology. Background technique [0002] With the intensification of the aging of Chinese society, more and more elderly people suffer from upper limb paralysis due to stroke and other reasons, which brings great inconvenience to daily life. Paralyzed patients need a lot of rehabilitation training to stimulate brain plasticity and restore a certain amount of exercise ability in order to achieve self-care, improve the quality of life, and return to society to the greatest extent. [0003] For limb motor dysfunction caused by stroke, traumatic brain injury, spinal cord injury, etc., accurate and quantitative rehabilitation function assessment is the basis for formulating rehabilitation prescriptions. For a long time, the evaluation methods of clinical reha...
