我尝试使用opencv和mediapipe编写手跟踪模块程序,但遇到了此错误。有人能帮助我吗?我使用的是opencv版本:4.6.0.66,媒体管道版本:0.8.11,以及Python版本:3.7
import cv2
import mediapipe as mp
import time
class handDetector():
def init(self, mode=False, maxHands=2, modelC=1, detectionCon=0.5, trackCon=0.5):
self.mode = mode
self.maxHands = maxHands
self.modelC = modelC
self.detectionCon = detectionCon
self.trackCon = trackCon
self.mpHands = mp.solutions.hands
self.hands = self.mpHands.Hands()
self.mpDraw = mp.solutions.drawing_utils
def findHands(self, img, draw=True):
imgRGB = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
result = self.hands.process(imgRGB)
#print(result.multi_hand_landmarks)
if result.multi_hand_landmarks:
for handLms in self.result.multi_hand_landmarks:
if draw:
self.mpDraw.draw_landmarks(img, handLms, self.mpHands.HAND_CONNECTIONS)
return img
def main():
ctime = 0;
ptime = 0;
cap = cv2.VideoCapture(0)
detector = handDetector()
while True:
success, img = cap.read()
img = detector.findHands(img)
ctime = time.time()
fps = 1 / (ctime - ptime)
ptime = ctime
cv2.putText(img, str(int(fps)), (10, 70), cv2.FONT_HERSHEY_PLAIN, 3, (255, 255, 255), 3)
cv2.imshow("Image", img)
cv2.waitKey(1)
if __name__ == "__main__":
main()
我遇到了这个错误。它说hands属性不是handDetector类的一部分:
Traceback (most recent call last):
File "/Users/ritessshhh/PycharmProjects/handtracking/main.py", line 48, in <module>
main()
File "/Users/ritessshhh/PycharmProjects/handtracking/main.py", line 36, in main
img = detector.findHands(img)
File "/Users/ritessshhh/PycharmProjects/handtracking/main.py", line 20, in findHands
result = self.hands.process(imgRGB)
AttributeError: 'handDetector' object has no attribute 'hands'

在Python中,默认的构造函数名为
__init__
(而不是init
)。尝试将handDetector
类的构造函数重命名为__init__
。(Also,将
handDetector
类别重新命名为HandDetector
可能是个好主意,以便将它(ClassName
)与regularVariable
区分开来。)
