# AIA MediaPipe 程式安裝

###### tags: `AIA`

要安裝Python程式可以使用anaconda建起一個虛擬環境,讓開發環境在新增各個所需套件時,能夠保持在anaconda上,讓開發環境比較乾淨

1. 安裝anaconda https://www.anaconda.com/products/distribution


3. 選擇uninstall,安裝OpenCV
4. 選擇uninstall,安裝Spyder
5. 開啟spyder

7.將media pipe的程式貼上,並且執行

import cv2
import mediapipe as mp



mp_drawing = mp.solutions.drawing_utils
mp_hands = mp.solutions.hands
hands = mp_hands.Hands(
        static_image_mode=False,
        max_num_hands=3,
        min_detection_confidence=0.5,
        min_tracking_confidence=0.5)



cap = cv2.VideoCapture(0) #("TestingVideo.avi")
while True:
    ret,frame = cap.read()
    frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
    # 因为摄像头是镜像的，所以将摄像头水平翻转
    # 不是镜像的可以不翻转
    frame= cv2.flip(frame,1)
    results = hands.process(frame)
    frame = cv2.cvtColor(frame, cv2.COLOR_RGB2BGR)
    if results.multi_handedness:
      for hand_label in results.multi_handedness:
          print(hand_label)   
    if results.multi_hand_landmarks:
      for hand_landmarks in results.multi_hand_landmarks:
          print('hand_landmarks:')
          print(hand_landmarks)
        # 关键点可视化
      mp_drawing.draw_landmarks(frame, hand_landmarks, mp_hands.HAND_CONNECTIONS)
    cv2.imshow('MediaPipe Hands', frame)
    if cv2.waitKey(1) & 0xFF == 27:
        break
cap.release()

9. 由於media pipe的模型需要另外安裝,所以執行會不成功,可在這裡打上
`pip install mediapipe`

> 10. 執行完成,就可以出現結果囉
