opensight-cv / opensight Goto Github PK

I create an issue here because it seems that I can't on opsi-gen.

First, thank you for what you are doing this is awesome !!
So, I tried to test the raspberry image but the camera didn't seem to work and the dashboard wasn't here. I decided to ssh into the raspberry and looked at the opensight service which had effectivly failed.
When I tried to manualy re-run the program, I had this issue :

Traceback (most recent call last):
  File "/bin/opensight", line 81, in <module>
    main()
  File "/bin/opensight", line 70, in main

Even though our camera was connected, Opensight could not detect the program as running. A test python program was run, testing if the camera was connected. The test program did provide video feed from the camera. After multiple trials, it was revealed that Opensight had a problem. I hope this can be fixed in the future.

In rare cases (currently only demonstrated through hardware issues) CameraInput will successfully create a VideoCapture object, however on the test run of the node the read() call will block until select times out (10 seconds, which is longer than the frontend XHR timeout). There should be a timeout for a more reasonable time, such as 1 second since a camera read should never take that long, and return the error properly.

Can you make a module that can save image frames and another than can read image frames for development & calibration?

Bonus points if there was a 'hook' page for capturing images, and another hook page for selecting which image to display.

Maybe the 'read image' module could have a feature to let it cycle though a folder of images like a slideshow. That way it would be quick to see how changing parameters affects a wide variety of input images.

When using the PutNT module, the pipeline fails to "compile" (the status indicator becomes a red X) if the PutNT module does not immediately receive an input that is not "None".
