Embodiment 1
[0080] see Figure 4 , a hand function evaluation method based on image processing technology, through an automatic detection of the degree of difference between the healthy hand and the affected hand, so as to complete the evaluation of the affected hand, which is characterized in that the operation steps are as follows:
[0081] (a) Start the hand function evaluation system: first turn on the power supply of the light source on the inner wall of the box, and the computer control system starts two cameras simultaneously;
[0082] (b) Obtain images of both hands: the patient puts his hand inside a special box, and obtains video images of the shape information of the patient's two hands;
[0083] (c) Unification of image scale: change the scale so that the images captured by different cameras are unified into the same scale;
[0084] (d) Remove noise and extract the shape of the hand: use the difference between the color of the hand and the background color to extract the shap...
Embodiment 2
[0095] This embodiment is basically the same as Embodiment 1, and the special features are as follows:
[0096] The step (a) described in the first embodiment starts the hand function evaluation system. The arrangement of multiple light sources on the inner wall of the box is used to eliminate shadows, reduce the difficulty of recognition caused by shadows, highlight the difference between the background color and the color of the hand, and improve the accuracy of hand shape extraction; during use, the two cameras need to Work at the same time to obtain the shape information of the left and right hands of the patient; when starting the system, first turn on the power supply of the light source on the inner wall of the box, and the computer control system starts the two cameras at the same time.
[0097] The step (b) obtains images of both hands, and these images include hand shape outline, handprint outline information, and background information.
[0098] The step (c) unifie...
