From Video device cannot capture the image.
显示 更早的评论
I am using the integrated webcam of my laptop to some image processing in Simulink. However, I have some problems to get the video. The block "To Video display" always displays a blackscreen.
The addon "Image Acquisition Toolbox Support Package for OS generic Video Interface" is installed as well. When I open the block of "From Video device", the webcam can be found.
"
However, by running the model, I get a black screen as follows. When I want to stop the simulation, the button "stop" in Simulink does not work. I have to use "cltr+c" in command window to stop it.
Can you help me?

I used the block and it works as expected in my machine. It may be the configuration issue of your machine, or you may need further troubleshooting.
- First, what do you see when you click "Preview" button in "From Video Device" block properties?
- Also, can you run the example in the doc correctly? Barcode Recognition Using Live Video Acquisition
- You can find official documentations for overall troubleshooting processes for Image Acquisition Toolbox. Please see if the docs can be of your help.
