This article mainly introduces OpenCV how to use gesture recognition to achieve virtual drag and drop effect, the article is very detailed, has a certain reference value, interested friends must read it!

The first step

Set the display box through opencv and call the camera to display the current screen.

Import cv2cap = cv2.VideoCapture (0) cap.set (3Power1280) cap.set (4720) while True: succes, img = cap.read () cv2.imshow ("Image", img) cv2.waitKey (1) step 2

To find the hand in the current screen, this article will use the hand tracking module in cv zone

From cvzone.HandTrackingModule import HandDetectordetector = HandDetector (detectionCon=0.8) # changed the default confidence level to make its detection more accurate

Find the complete code for the hand

Import cv2from cvzone.HandTrackingModule import HandDetectorcap = cv2.VideoCapture (0) cap.set (3Power1280) cap.set (4720) detector = HandDetector (detectionCon=0.8) while True: succes, img = cap.read () detector.findHands (img) lmList, _ = detector.findPosition (img) cv2.imshow ("Image", img) cv2.waitKey (1)

Step three

The third step is to create a square first

Cv2.rectangle (img, (100100), (300300), (0,0,255), cv2.FILLED)

Then check to see if our index finger enters the box, and if so, the box changes color

If lmList: cursor = lmList [8] if 100
