1 简要介绍

说明：此方法可能有一定的缺陷，但是我认为有一定的实现可能所以做了这个板块。倘若有专业的中医医生或者相关工作者对此有建议或者意见可以与我联系交流哦~
关于手掌我这里有手掌的图片数据集可供大家下载：手掌数据集

穴位按摩是中国医学的重要组成部分，它是以中国医学理论为指导，以经络腧穴学说为基础，以按摩为主要施治，用来防病治病的一种手段。为方便用户可以随时随地按摩手部穴位，中e诊开发了智能手部穴位定位系统，使用户可以准确地找到手心与手背的穴位。具体功能为用户上传一张其手心或手背照片，系统会自动定位照片中的穴位坐标，并在图中标记处穴位位置，并将标记图片返回给用户。以左手手心为例，操作结果如下图所示：

2 技术详情

为准确定位到图像中的手掌位置，本小组利用mediapipe开发的手部界标模型（MediaPipe Hands）定位到手部关键节点。MediaPipe Hands 是一种高保真手和手指跟踪解决方案。它使用机器学习 (ML) 从单帧中推断出一只手的 21 个 3D 地标。具体21个3D地标如下图所示：

通过MedisPipe Hands手掌定位地标分析，可将上一节中的用户图片代入分析，计算该图手掌的关键节点。计算效果如下图所示：

在明确手掌在图中的关键节点后。本小组通过查阅大量中医文献书籍与资料，找到常见的手掌穴位在手部的相对位置。通过手部关键节点的位置坐标，采用欧式距离计算出图像中穴位的位置坐标并进行标注。同时，可以通过拇指指尖二维纵坐标与小拇指指尖二维纵坐标的大小判断图像中的是手心或是手背。手背智能穴位定位效果如下图所示：

3 代码实现

3.1 导入相应的库

import cv2 as cv
import numpy as np
import mediapipe as mp
import  tqdm
import time
import  matplotlib.pyplot as plt
from PIL import Image, ImageDraw, ImageFont

ps：在导入cv2时我遇到了一个报错“DLL load failed while importing cv2: 找不到指定的模”。若大家也遇到这种问题可至成功解决Python导入opencv报错“DLL load failed while importing cv2: 找不到指定的模”查看解决方法。

3.2 定义在图片中画点写字的函数

这一步方便在计算出穴位坐标后利用该函数对图片进行标记。

def cv2ImgAddText(img, text, left, top, textColor=(0, 255, 0), textSize=20):
    if (isinstance(img, np.ndarray)):  # 判断是否OpenCV图片类型
        img = Image.fromarray(cv.cvtColor(img, cv.COLOR_BGR2RGB))
    # 创建一个可以在给定图像上绘图的对象
    draw = ImageDraw.Draw(img)
    # 字体的格式
    fontStyle = ImageFont.truetype(
        "simsun.ttc", textSize, encoding="utf-8")
    # 绘制文本
    draw.text((left, top), text, textColor, font=fontStyle)
    # 转换回OpenCV格式
    return cv.cvtColor(np.asarray(img), cv.COLOR_RGB2BGR)

3.3 定义手部关键点监测模型并导入

# 手部关键点检测模型
mp_hand=mp.solutions.hands

# 导入模型
hands=mp_hand.Hands(static_image_mode=False,
                    max_num_hands=1,
                    min_detection_confidence=0.3,
                    min_tracking_confidence=0.3
                    )

3.4 导入绘图函数

# 导入绘图函数
mpDraw=mp.solutions.drawing_utils
img=cv.imread(r'C:\Users\13267\Desktop\test\hand2.jpg')#需要标记的手掌图片的位置
#look_img(img)
img_RGB=cv.cvtColor(img,cv.COLOR_BGR2RGB)
results=hands.process(img_RGB)
lmList = []

3.5 将原本三维的坐标系转为2维方便平面坐标计算

if results.multi_hand_landmarks:
    for handLms in results.multi_hand_landmarks:
        for id, lm in enumerate(handLms.landmark):
            h, w, c = img.shape
            cx, cy = int(lm.x * w), int(lm.y * h)
            lmList.append([id, cx, cy])

3.6 计算手部穴位的函数

这里利用了小拇指指尖坐标与大拇指指尖坐标的相对位置来判断图片是手掌还是手背。目前仅能左手来测试！
