Displaying continuous grabbing from basler camera and show it on Tkinter GUI

[fatmafarah]

I am trying to feed my gui written with tkinter python with live camera capture with Basler camera USB3. I wrote this code but it's not working. My camera is Basler daA1280-54um (23625361). I want to capture the video and show it in a label or frame, and when there is hardware trigger in the camera take that image and show it in a different label.

` from pypylon import pylon import cv2 from tkinter import * from PIL import Image, ImageTk

  def video_stream():
           tlf = pylon.TlFactory.GetInstance()
           cam = pylon.InstantCamera(tlf.CreateFirstDevice())
          cam.Open()
          cam.UserSetSelector = 'Default'
          cam.UserSetLoad.Execute()
          cam.PixelFormat.SetValue('Mono8')
          cam.Gain.SetValue(17.9)
          cam.ExposureTime.SetValue(60.0)
         cam.TriggerMode.SetValue('Off')
         cam.Gain.SetValue(17.9)
         cam.ExposureTime.SetValue(60.0)

        # Grabing Continusely (video) with minimal delay
      cam.StartGrabbing(1)
      converter = pylon.ImageFormatConverter()

       # converting to opencv bgr format
       converter.OutputBitAlignment = pylon.OutputBitAlignment_MsbAligned

        while cam.IsGrabbing():

            grabResult = cam.RetrieveResult(pylon.waitForever, pylon.TimeoutHandling_ThrowException)

            if grabResult.GrabSucceeded():

                     image = converter.Convert(grabResult)
                     b = cam.LineStatus.GetValue()
                     if b==True: #if there is a hardware triggerer, show the image
                        cam.Gain.SetValue(17.9)
                        cam.ExposureTime.SetValue(60.0)
                        img1 = image.GetArray()
                        cv2image = cv2.cvtColor(img1, cv2.COLOR_BGR2RGBA)
                        img = Image.fromarray(cv2image)
                        imgtk = ImageTk.PhotoImage(image=img)
                        lmain2.imgtk = imgtk
                        lmain2.configure(image=imgtk)
                       # Access the image data
                   else:
                         print('im here')
                         cam.Gain.SetValue(17.9)
                         cam.ExposureTime.SetValue(60.0)
                         img1 = image.GetArray()
                         cv2image = cv2.cvtColor(img1, cv2.COLOR_BGR2RGBA)
                        img = Image.fromarray(cv2image)
                        imgtk = ImageTk.PhotoImage(image=img)
                         lmain.imgtk = imgtk
                         lmain.configure(image=imgtk)
                         k = cv2.waitKey(1)
                          if k == 27:
                               break
               grabResult.Release()

root=Tk() app = Frame(root, bg="white") app.grid()

Create a label in the frame

lmain1 = Label(app) lmain2 = Label(app) lmain1.grid(row=0,column=0) lmain2.grid(row=0,column=1) root.mainloop()`

Can someone tell me why it's not working

have you checked with : https://github.com/basler/pypylon/issues/72#issuecomment-687710210

for better readability, please edit your issue and remove the single ticks ( these are only for one-line code ) and replace by ``` ...code ...``` In the edit window of the issues you even have a button for code pasting. just select all lines of code and click

Technical question: what do you want to reach with ? cam.StartGrabbing(1)
