Open-CV to Tkinter Python 

การแสดงภาพและการปรับพารามิเตอร์จาก GUI Tkinter 

การแสดงภาพจากกล้อง Webcam มีรูปแบบดังนี้

1. import tkinter as tk

2. from tkinter import Label, Scale

3. from PIL import Image, ImageTk

4. import cv2

5. import numpy as np

6. 
   

7. # Function to adjust brightness

8. def adjust_brightness(frame, brightness):

9.     # Convert brightness value to a factor (e.g., 0.5 to 1.5)

10.     brightness_factor = brightness / 50  # Scale from 0 to 100 to 0.0 to 2.0

11.     # Apply brightness adjustment

12.     adjusted_frame = cv2.convertScaleAbs(frame, alpha=brightness_factor, beta=0)

13.     return adjusted_frame

14. 
    

15. def show_frames():

16.     ret, frame = cap.read()

17. 
    

18.     if ret:

19.         brightness = brightness_slider.get()

20. 
    

21.         # Adjust the brightness of the frame

22.         frame = adjust_brightness(frame, brightness)

23.         frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)

24. 
    

25.         # Convert the frame to an image that Tkinter can display

26.         img = Image.fromarray(frame)

27.         imgtk = ImageTk.PhotoImage(image=img)

28. 
    

29.         # Update the label with the new image

30.         label.imgtk = imgtk  

31.         label.configure(image=imgtk)

32. 
    

33.     label.after(10, show_frames)

34. 
    

35. cap = cv2.VideoCapture(0)

36. 
    

37. root = tk.Tk()

38. root.title("Webcam Feed in Tkinter")

39. root.geometry("1000x1000+100+100") 

40. 
    

41. label = Label(root)

42. label.pack()

43. label.place(x=10, y=150)

44. 
    

45. # Create a slider for brightness control

46. brightness_slider = Scale(root, from_=0, to=100, length=500, orient=tk.HORIZONTAL, label="Brightness")

47. brightness_slider.set(50)  # Set default brightness to 50

48. brightness_slider.pack()

49. brightness_slider.place(x=10, y=50)

50. 
    

51. show_frames()

52. root.mainloop()

53. cap.release()
