Error when trying to connect a JAI AD_132GE#1 camera with Python, using the Harvester library

[G-S-A]

I am starting to use IP cameras, and I have to capture an image, specifically from the JAI AD-132GE camera using Python, I am starting by using the Harvester library, however I have not been able to obtain images.

I have used the tool that JAI provides JAI Camera Control Tool and with it I can perform the image acquisition:

However, when I try to link it in Python I get an error, this is the code:

 `
 import cv2
 import numpy as np
 import matplotlib.pyplot as plt
 from harvesters.core import Harvester 

 # create harvester object
 h = Harvester()
 h.add_file("c:/Program Files/JAI/SDK/bin/JaiGevTL.cti")
 h.update()
 h.device_info_list[0]

 # create image acquirer
 ia = h.create(0)
 width = 2560
 height = 1960
 ia.device.node_map.Width.value, ia.device.node_map.Height.value = width, height
 ia.device.node_map.PixelFormat.value = 'Mono8'

 # create videowriter
 fourcc = cv2.VideoWriter_fourcc(*'XVID')
 fps = 25.0
 out = cv2.VideoWriter('output.avi',fourcc, fps, (width,height))

 # start image aq
 ia.start()
 while(True):
     with ia.fetch_buffer() as buffer:
         # Let's create an alias of the 2D image component:
         component = buffer.payload.components[0]

         #     # Let's see the acquired data in 1D:
         #    _1d = component.data

         # Reshape the NumPy array into a 2D array:
         frame = component.data.reshape(component.height, component.width)

         # perform any operation on the image

         # convert to bgr for video saving
         frame = cv2.cvtColor(frame, cv2.COLOR_GRAY2BGR) 

         # save frames
         out.write(frame)

         # save snapshot
         #    cv2.imwrite('snap.jpg', frame)

         # show live acquisition
         cv2.imshow('frame',frame)

         # exit live aq with "q"-key
         if cv2.waitKey(1) & 0xFF == ord('q'):
             break

 out.release()
 cv2.destroyAllWindows()
 ia.stop_image_acquisition()
 ia.destroy()
 h.reset()`

If i print device_info_list:

[{'access_status': 2, 'display_name': 'AD-132GE_#0', 'id_': 'MAC->00-0C-DF-08-40-14::JAI Ltd., Japan::AD-132GE_#0', 'model': 'AD-132GE_#0', 'parent': <genicam.gentl.Interface; proxy of <Swig Object of type 'std::shared_ptr< GenTLCpp::TLInterface > *' at 0x0000022E26E1E450> >, 'serial_number': 'QV132321', 'thisown': True, 'tl_type': 'GEV', 'user_defined_name': '', 'vendor': 'JAI Ltd., Japan', 'version': None}, {'access_status': 2, 'display_name': 'AD-132GE_#0', 'id_': 'MAC->00-0C-DF-08-40-14::JAI Ltd., Japan::AD-132GE_#0', 'model': 'AD-132GE_#0', 'parent': <genicam.gentl.Interface; proxy of <Swig Object of type 'std::shared_ptr< GenTLCpp::TLInterface > *' at 0x0000022E26E1E870> >, 'serial_number': 'QV132321', 'thisown': True, 'tl_type': 'GEV', 'user_defined_name': '', 'vendor': 'JAI Ltd., Japan', 'version': None}]

This is the error it gives me when running the program:

i have: genicam 1.3.0 harvesters 1.4.2 Python 3.7.0

I would appreciate if anyone has an idea of ​​what the error could be and could educate me on the subject, greetings.

I have the same problem with a FLIR thermal camera Did you solve the problem?

[polanco06]

I have the same problem with a Teledyne thermal camera Has anyone solved it or saved how to solve it?

I've solved it, but the scritp that aquire the image is running locally.

1. You have to install the Python SDK for your system and the program from the url: https://www.flir.eu/products/spinnaker-sdk/?vertical=machine+vision&segment=iis
2. You need to login with an email.
3. Download the programs compatible with your operating system version (you must download the python library and the program).
4. Follow the instructions in the README.md to install.
5. Use the "simple_pyspin" library, it is a library that uses PySpin in the background but much easier to use, I recommend you to download the github repository and make tests directly from the scripts the developer has
