I tried to run the below mentioned Example code. but I got an Attribute error saying

AttributeError: module 'cvzone' has no attribute 'HandDetector'.

Help me to resolve this issue.

the Example code is.

import cvzone
import cv2

cap = cv2.VideoCapture(0)
cap.set(3, 1280)
cap.set(4, 720)
detector = cvzone.HandDetector(detectionCon=0.5, maxHands=1)

while True:
    # Get image frame
    success, img = cap.read()

    # Find the hand and its landmarks
    img = detector.findHands(img)
    lmList, bbox = detector.findPosition(img)

    # Display
    cv2.imshow("Image", img)
    cv2.waitKey(1)

Hello! Maybe try from cvzone.HandTrackingModule import HandDetector and do detector = HandDetector(detectionCon=0.0, maxHands=1)

its-Yogesh commented 2 years ago

Thanks for you Advice but still it shows the same error.

Make sure mediapipe is installed. Try: import cv2 from cvzone.HandTrackingModule import HandDetector

cap = cv2.VideoCapture(0) cap.set(3, 1280) cap.set(4, 720) detector = HandDetector(detectionCon=0.8, maxHands=1)

Hey its-Yogesh, what francoisschwarxentruber said is right. Try this:

from cvzone.HandTrackingModule import HandDetector import cv2

cap = cv2.VideoCapture(0) detector = HandDetector(detectionCon=0.8, maxHands=2) while True:

    # Hand 1
    hand1 = hands[0]
    lmList1 = hand1["lmList"]  # List of 21 Landmark points
    bbox1 = hand1["bbox"]  # Bounding box info x,y,w,h
    centerPoint1 = hand1['center']  # center of the hand cx,cy
    handType1 = hand1["type"]  # Handtype Left or Right

    fingers1 = detector.fingersUp(hand1)

    if len(hands) == 2:
        # Hand 2
        hand2 = hands[1]
        lmList2 = hand2["lmList"]  # List of 21 Landmark points
        bbox2 = hand2["bbox"]  # Bounding box info x,y,w,h

        fingers2 = detector.fingersUp(hand2)

        # Find Distance between two Landmarks. Could be same hand or different hands
        length, info, img = detector.findDistance(lmList1[8], lmList2[8], img)  # with draw

Thanks! @Mandizvidzafn But when I set maxHands to 2, It gives me an Error!

Of cource no!

ErandiJayaweera commented 1 year ago

from cvzone.HandTrackingModule import HandDetector put this line when your import/calling your libraries. then check if it works. this worked for me

jonetwo commented 1 year ago

Mine could work, check wether have you downloaded the mediapipe, or you can change a version of cvzone. Wish you the best.

There's a small modification, since while calculating it accepts 3 values hence the updated code should be:

from cvzone.HandTrackingModule import HandDetector
import cv2

cap = cv2.VideoCapture(0)
detector = HandDetector(detectionCon=0.8, maxHands=1)
while True:

# Get image frame
    success, img = cap.read()
# Find the hand and its landmarks
    hands, img = detector.findHands(img) # with draw
#hands = detector.findHands(img, draw=False) # without draw
    if hands:
        # Hand 1
        hand1 = hands[0]
        lmList1 = hand1["lmList"]  # List of 21 Landmark points
        bbox1 = hand1["bbox"]  # Bounding box info x,y,w,h
        centerPoint1 = hand1['center']  # center of the hand cx,cy
        handType1 = hand1["type"]  # Handtype Left or Right

        fingers1 = detector.fingersUp(hand1)

        if len(hands) == 2:
            # Hand 2
            hand2 = hands[1]
            lmList2 = hand2["lmList"]  # List of 21 Landmark points
            bbox2 = hand2["bbox"]  # Bounding box info x,y,w,h
            centerPoint2 = hand2['center']  # center of the hand cx,cy
            handType2 = hand2["type"]  # Hand Type "Left" or "Right"

            fingers2 = detector.fingersUp(hand2)

            # Find Distance between two Landmarks. Could be same hand or different hands
            # Now you see that in findDistance, x1,y1 = p1 , this will give you error since x1, y1, z1 = p # It should be like this
             length, info, img = detector.findDistance(lmList1[8][:2], lmList2[8][:2], img)
            # length, info, img = detector.findDistance(lmList1[8], lmList2[8], img)  # with draw
            # length, info = detector.findDistance(lmList1[8], lmList2[8])  # with draw
