Problems solved by technology

[0005] Pain drawings provide surgeons with a tool to understand the location and nature of pain in patients, but the current pain drawings have the following deficiencies: (1) The outline of the human body in pain drawings is a two-dimensional plane, while the human body is a three-dimensional structure, so based on Human pain drawings of flat models cannot accurately display accurate information highly correlated with the distribution area of ​​nerve root symptoms
Each nerve root has its main innervated sensory area, which

Embodiment Construction

[0033] Below, combine Figure 1-11 The present invention will be described in detail.

[0034] The implementation process of mobile terminal-based 3D human body model operation and pain zone definition is as follows.

[0035] 1. Generation of 3D human body model

[0036] The three-dimensional human body model used in the present invention is modeled and generated by the character modeling design software Poser7. First, select the P4NudeMan male human body model in the character model library in the poser7 software, and then modify the model limb rotation, displacement and other parameters to obtain the existing model, and finally output it as an obj model source file.

[0037] 2. Data preprocessing:

[0038] Due to the limited CPU computing power of ordinary mobile terminals, such as PAD, if the 3D human body model is directly loaded into the PAD for real-time rotation and pain area drawing, it will cause picture freezes and inaccurate pixel accuracy capture due to slow pro...

Abstract

The invention relates to a quantitative evaluation method for the pain of a subject. The method comprises the steps of painting painful positions in predetermined colors on a preset three-dimensional human model to represent pain types and pain areas, wherein the predetermined colors are various different colors, each color is corresponding to one pain type and the number of pixels at the painted pain areas represents the pain degree; and showing a cross section drawing at a selected position of the three-dimensional human model and further marking the pain positions of the subject on the cross section drawing to reflect the pain depth of the subject.

Description

technical field [0001] The present invention relates to quantitative evaluation of pain, in particular to a method for quantitative evaluation of pain on a subject and a system for implementing the method. Background technique [0002] Pain is the most common clinical symptom and a complex physiological and psychological activity. The International Pain Society defines pain as: an unpleasant sensory and emotional experience associated with existing or potential tissue damage. At present, pain has become the fifth vital sign following the four vital signs of body temperature, pulse, respiration, and blood pressure, and has been increasingly valued by the international community. [0003] Compared with the first four signs, pain is very special: there is still no objective biological instrument to detect pain and describe the degree of pain. In fact, pain is a subjective experience, so it is difficult to have objective tools to measure pain levels. With the deepening of sci...
