带有Python TypeError的手势鼠标：预期为整数参数，浮点数

Question

错误在第65行。我似乎无法弄清楚。该代码用于使用网络摄像头的手势控制鼠标。

我曾尝试将“ img”类型转换为整数，但由于它是标量值，因此无法完成。

import cv2
import numpy as np
from pynput.mouse import Button, Controller
import wx
mouse=Controller()

app=wx.App(False)
(sx,sy)=wx.GetDisplaySize()
(camx,camy)=(320,240)

lowerBound=np.array([33,80,40])
upperBound=np.array([102,255,255])

cam = cv2.VideoCapture(0)

kernelOpen=np.ones((5,5))
kernelClose=np.ones((20,20))
pinchFlag=0

while True:
    ret, img=cam.read()
    img=cv2.resize(img,(camx,camy))

    #convert BGR to HSV
    imgHSV= cv2.cvtColor(img,cv2.COLOR_BGR2HSV)
    # create the Mask
    mask=cv2.inRange(imgHSV,lowerBound,upperBound)
    #morphology
    maskOpen=cv2.morphologyEx(mask,cv2.MORPH_OPEN,kernelOpen)
    maskClose=cv2.morphologyEx(maskOpen,cv2.MORPH_CLOSE,kernelClose)

    maskFinal=maskClose
    _,conts,h=cv2.findContours(maskFinal.copy(),cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_NONE)

    if(len(conts)==2):
        if(pinchFlag==1):
            pinchFlag=0
            mouse.release(Button.left)
        x1,y1,w1,h1=cv2.boundingRect(conts[0])
        x2,y2,w2,h2=cv2.boundingRect(conts[1])
        cv2.rectangle(img,(x1,y1),(x1+w1,y1+h1),(255,0,0),2)
        cv2.rectangle(img,(x2,y2),(x2+w2,y2+h2),(255,0,0),2)
        cx1=x1+w1/2
        cy1=y1+h1/2
        cx2=x2+w2/2
        cy2=y2+h2/2
        cx=(cx1+cx2)/2
        cy=(cy1+cy2)/2
        cv2.line(img, (cx1,cy1),(cx2,cy2),(255,0,0),2)
        cv2.circle(img, (cx,cy),2,(0,0,255),2)
        mouseLoc=(sx-(cx*sx/camx), cy*sy/camy)
        mouse.position=mouseLoc 
        while mouse.position!=mouseLoc:
            pass
    elif(len(conts)==1):
        x,y,w,h=cv2.boundingRect(conts[0])
        if(pinchFlag==0):
            pinchFlag=1
            mouse.press(Button.left)
        cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
        cx=x+w/2
        cy=y+h/2
        cv2.circle(img,(cx,cy),(w+h)/4,(0,0,255),2)
        mouseLoc=(sx-(cx*sx/camx), cy*sy/camy)
        mouse.position=mouseLoc 
        while mouse.position!=mouseLoc:
            pass
    cv2.imshow("cam",img)
    cv2.waitKey(5)

据我所知，这些值必须浮点数才能正常运行。
