I tried the same code on Ubuntu 18.04.6 LTS using Visual Studio Code. I can view the camera (index 4) using your test_cameras.py utility and the camera works great. OpenCV is version 3.2.0 and Python is version 3.6.9
Thanks again, any help is appreciated.
Hi, do you mean that you have all four cameras correctly installed, and you can open each of them individually, but when running the run_live_demo.py
, you cannot see the birdview image and no error is reported?
Hello! Yes, I have 4 web cameras plugged into a laptop. I used your tool to get their index numbers and was trying to run them in run_live_demo.py, but can't seem to get past that "Cannot open camera" error. All the cameras just say cannot open camera #.
Is there maybe a version of something I might have wrong?
By default the code opens your camera with libgstreamer, while the code in test_camera.py
simply tries to open it using USB. You may need to set the parameter use_gst=True
to False
.
And this project cannot create the birdview if you haven't calibrated your cameras, and do the manual projection calibration step. Have you read the documentation?
I see. That completely makes sense. Would it be hard to modify the code to use an external http (IP Camera)? I would like to eventually use a URL like 'http://192.168.0.90/mjpg/video.mjpg'. The eventual goal of this would be to try using your code on a shiploader. It's a huge machine that loads vessels.
The actual camera device doesn't make any difference: you just need to set the way how it's opened in the capture_thread.py
.
Trying to get Run_Live_Demo.py to work in Windows 10 running Python 3.12.2 (tags/v3.12.2:6abddd9, Feb 6 2024, 21:26:36) [MSC v.1937 64 bit (AMD64)], I have OpenCV 4.9.0.
When I run Run_Live_Demo.py, the attached webcam turns on, but I do not see a pop-up with a birds eye view of the car with my camera in it. I can run run_get_projection_maps.py and that works fine, but for some reason not Run_Live_Demo.py
My webcam is index 1. There are no errors - as far as I can tell.
Any ideas?
