Embodiment 1

[0023] In this example, see figure 1 and figure 2 , a quantitative evaluation system for the degree of rehabilitation of lower limbs using motion capture sensors, including motion posture sensor system I and automated intelligent computer system II, motion posture sensor system I is composed of 18 network hub master node devices and 17 sensor nodes, the network hub master The node device 18 is a wearable electronic device, and each sensor node is a wearable wireless motion capture sensor unit, which can be respectively worn and installed on a set position of the human body. Each motion capture sensor unit of the motion posture sensor system I includes a head Front sensor node 1, back sensor node 2, waist sensor node 3, left shoulder sensor node 4, right shoulder sensor node 5, left upper arm sensor node 7, right upper arm sensor node 6, left forearm sensor node 9, right forearm sensor node Sensor node 8, left palm sensor node 11, right palm sensor node 10, left thigh sensor ...

Embodiment 2

[0032] This embodiment is basically the same as Embodiment 1, especially in that:

[0033] In this embodiment, the movement data of human body parts collected by each motion capture sensor unit of the motion posture sensor system I is collected on the network hub master node device 18, and then the network hub master node device 18 transmits the data in a Wi-Fi wireless manner Transfer to the automated intelligent computer system II. Using Wi-Fi wireless instead of wired data lines makes the device simpler and more convenient to use.

Abstract

The invention discloses a lower limb rehabilitation degree quantitative evaluation system adopting a motion capture sensor and an evaluation method. The system comprises the motion capture sensor and a display system and further comprises motion capture sensing equipment and an automatic intelligent computer system. By means of a sensor motion capture device and method, the defects that parameter types measured through current lower limb rehabilitation degree evaluation are limited, and precision is poor are overcome, and the concept of upper and lower limb integration is verified through quantitative data. A three-dimensional human body model driven by a patient can be displayed on a screen in real time in the quantitative evaluation process, the patient can correct postures of himself / herself in the process, and great significance and value are achieved for human body health recovery and clinical medicine.

Description

technical field [0001] The present invention relates to a human body rehabilitation system device and its application, in particular to a motion capture system and its application in quantitatively evaluating the degree of rehabilitation of human movement parts, which belongs to the field of electronic information, and particularly relates to the field of medical rehabilitation of upper and lower limbs The concept of integration belongs to the new generation of strategic new industries of information technology. Background technique [0002] At present, there are two main ways to evaluate the degree of rehabilitation of lower limbs: the first method is to score the scale, and to evaluate the stage of lower limb rehabilitation by scoring the actual situation of several basic movements of the lower limbs. This method is qualitative and subjective. Strong and inefficient. The second method is to directly measure the distance and time manually, record the gait cycle with a stop...
