Question

我不会用英语说话，但我试图创建滑块以改变HSV（色调饱和度和值）的值。我创建了6个滑块，我能够打印它们的值。我想创建6个滑块来修改图像的Hue min，Hue max，Sat max，Sat min，Val min，Val max并使用相同的按钮更新它。我不知道问题是否在inRange函数中。也许我不能创建一个标签来显示图像。

是的，有人可以帮帮我吗？谢谢！

我收到了这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__
 return self.func(*args)
File "C:\Python27\hsv_trackbar.py", line 109, in makeSomething
imgthresh1=cv2.inRange(imghsv,lw_range,up_range)
TypeError: lowerb data type = 18 is not supported

这是代码：

from Tkinter import Tk, Label, SOLID

img = cv2.imread('C:\python27\Archivos\image02.jpg')
imghsv = cv2.cvtColor(img,cv2.COLOR_BGR2HSV)
