I got a big problem at python code, my code is work correct but my laptop's RAM cant erase unused data, I used 'gc' library but it doesn't any help, this problem went appear that I change it to class mode.
my code:
import cv2 as cv
import mediapipe as mp
import time
import gc
class handDetector():
def __init__(self, mode=False, maxHands=2, detectionCon=0.5, trackCon=0.5):
self.mode = mode
self.maxHands = maxHands
self.detectionCon = detectionCon
self.trackCon = trackCon
self.mpHands = mp.solutions.hands
self.hands = self.mpHands.Hands(self.mode, self.maxHands, 1, self.detectionCon, self.trackCon)
self.mpDraw = mp.solutions.drawing_utils
def findHands(self, image, draw=True):
imgRGB = cv.cvtColor(image, cv.COLOR_BGR2RGB)
self.result = self.hands.process(imgRGB)
if self.result.multi_hand_landmarks:
for hand in self.result.multi_hand_landmarks:
if draw:
self.mpDraw.draw_landmarks(image, hand, self.mpHands.HAND_CONNECTIONS)
cv.FILLED)
return image
def findPosition(self, image, handNo=0, draw=True):
lmList = []
h, w, c = image.shape
if self.result.multi_hand_landmarks:
myHand = self.result.multi_hand_landmarks[handNo]
for id, land in enumerate(myHand.landmark):
cx, cy = int(land.x * w), int(land.y * h)
lmList.append([id, cx, cy])
if draw:
cv.circle(image, (cx,cy), 15, (0,0,255), cv.FILLED)
return lmList
def main():
cap = cv.VideoCapture(0)
ret=1
pre_time = time.time()
gc.enable()
while ret:
ret, frame = cap.read()
crt_time = time.time()
fps = int(1/(crt_time-pre_time))
handDtc = handDetector()
image = handDtc.findHands(frame)
lmList = handDtc.findPosition(image)
cv.putText(image, str(fps), (50,50), cv.FONT_HERSHEY_COMPLEX, 1, (255,255,0))
image=frame
cv.imshow('image', image)
pre_time = time.time()
if cv.waitKey(1) == ord('q'):
ret = False
# print(lmList)
del handDtc
del image
gc.collect()
if __name__ == "__main__":
main()
my RAM storage is 16gb and I have 11gb free, after running the code my RAM will full
CodePudding user response:
I have to remove handDtc = handDetector()
inside the while to the outside.
this line make many class object and it will full my RAM.
