上一篇博客我们介绍了mediapipe库和对手部进行了检测,这次我们进行手部关键点的连线
代码实现
import cv2
import mediapipe as mp
cap = cv2.VideoCapture(1)
mpHands = mp.solutions.hands
hands = mpHands.Hands()
mpDraw = mp.solutions.drawing_utils
while True:
success, img = cap.read()
imgRGB = cv2.cvtColor(img,cv2.COLOR_BGR2RGB)
#对RGB图像进行手部检测
results = hands.process(imgRGB)
print(results.multi_hand_landmarks)
#检查是否检测到任何手部关键点
if results.multi_hand_landmarks:
#遍历每个检测到的手部
for handLms in results.multi_hand_landmarks:
mpDraw.draw_landmarks(img, handLms,mpHands.HAND_CONNECTIONS)
cv2.imshow("image", img)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
效果演示
这样手部关键点和连接线就画好了,有兴趣的可以关注一下,谢谢
