Problems solved by technology

In the evaluation process, professional doctors are required to measure and evaluate. Due to the individual differences of the measurers, the judgment standard range is relatively large, and the direct changes in these ranges of 110%-75%-50%-0% cannot be carefully distinguished. For the training process The detailed changes cannot be reflected, resulting in the inability to adjust the training program in time during the rehabilitation training process, which seriously affects the training effect. Moreover, the current evaluation methods are very subjective and unreliable

Embodiment 1

[0123] see figure 1 , the present invention is based on the hand function evaluation device that each part of the hand changes in three-dimensional space, including:

[0124] A hand function evaluation device based on the position changes of various parts of the hand in three-dimensional space, including two identical obscura (1, 2) on the left and right, and the internal color of the obscura (1, 2) is significantly different from the color of the hand; each (1, 2) is divided into upper and lower parts, separated by a partition (7) that does not affect the work of the somatosensory controller (5); a camera device (3) is respectively installed on the top of each camera obscura (1, 2); Several surface light sources (8) are respectively installed in the inside of each dark box (1, 2); one side of each dark box (1, 2) has an entrance (6) where a hand is stretched in close to the middle grid (7) ); a piece of shading cloth (4) is placed on the outside of each entrance (6), the co...

Embodiment 2

[0126] see figure 2 , the present invention is based on the hand function evaluation device that each part of the hand changes in three-dimensional space, including:

[0127] A hand function evaluation device based on the position changes of various parts of the hand in three-dimensional space, comprising a camera obscura (1'), the color of the inside of the camera camera obscura (1') is clearly distinguished from the color of the hand; the camera camera obscura (1') is divided into upper and lower two The two parts are separated by a partition (7') that does not affect the work of the somatosensory controller (5'); the upper part is separated from the middle by a light-proof partition (9'), and is divided into two small dark boxes on the left and right; The color of the middle impermeable partition (9') is consistent with the color inside the camera obscura (1'); a camera device (3') is respectively installed on the top of each small camera obscura; A surface light source (...

Embodiment 3

[0129] see figure 1 , figure 2 and Figure 4 , the present invention is based on the hand function evaluation method of the position changes of various parts of the hand in three-dimensional space, and the application figure 1 and figure 2 The device is operated to obtain various information of the hand in the three-dimensional space by using the camera equipment and the somatosensory controller of the hand posture, and completes the hand function evaluation according to these information, and is characterized in that the operation steps are as follows:

[0130] 1. Start the hand function evaluation system;

[0131] 2. Put your hand into the hand function evaluation system;

[0132] 3. Obtain real-time video information of the hand;

[0133] 4. Obtain the three-dimensional space position information of the hand;

[0134] 5. Determine the position of the palm of the affected hand;

[0135] 6. Transform the origin position and three-dimensional space coordinates of the a...

Abstract

The invention relates to a hand function evaluation device and a method based on the position change of each part of a hand in a three-dimensional space. The device comprises a left camera obscura and a right camera obscura or one camera obscura with the upper part thereof separated into two portions, wherein the left camera obscura and the right camera obscura are arranged parallel to each other. The top of each camera obscura is provided with a light source and an image pickup device. The bottom of each camera obscura is provided with a somatosensory controller. The middle part of each camera obscura is provided with a hand inlet / outlet. According to the technical scheme of the invention, the method is applied to a hand function evaluation device to detect an affected-side hand and a healthy-side hand. Meanwhile, the differentiation degree between the affected-side hand and the healthy-side hand is detected, so that the evaluation of the affected-side hand is completed. Moreover, the digitized, systematized and standardized measurement of the recovery state of the hand function is realized, so that doctors can be facilitated to objectively evaluate the rehabilitation condition of the hand of a patient and make a correct judgment. As a result, an effective treatment regimen can be proposed. Therefore, the device and the method provide a powerful help for the early rehabilitation of the patient.

Description

technical field [0001] The invention relates to a hand function evaluation device and method based on the position changes of various parts of the hand in three-dimensional space. It is applied in the hand function evaluation system to automatically detect the difference between the affected hand and the healthy hand, and the difference between the affected hand and the standard hand, so as to complete the evaluation of the affected hand. This invention can digitize, systematize and standardize the recovery of hand function, and help doctors objectively evaluate the recovery of the patient's hand, make correct judgments, and propose effective treatment plans, so that patients can recover as soon as possible. technical background [0002] Hand function evaluation refers to the comparison of the patient's affected hand with the healthy hand or the standard hand during the rehabilitation process, so as to obtain the degree of disability and rehabilitation of the affected hand. ...
