OpenNI2 Color Stream Status

Hey there!

Can anyone clarify if the color stream is available in OpenNI2?

This post mentions that it's accessible. https://3dclub.orbbec3d.com/t/record-from-astra-with-python-and-openni/2228 other posts seem to say it isn't available.

I seem to be getting a None type returned form dev.create_color_stream()

Using OpenCV2, I can grab the camera using VideoCapture, but, the lag between this and the depth stream is pretty nasty.

Any pointers would be much appreciated

Hi, I created the post you mention.
It depends on the sensor. For Astra and Astra S the color stream is availaible through OpenNI2 while it is not for Astra Pro. Check my repo here: https://github.com/roccopietrini/pyOniRecorder for the complete example. I use Astra S and Astra.

Thanks @rok for the reply, guess I need to order another camera

Quite happy that I've managed to get the thing compiled up and depth sensing running quite happily on a Pi 3a+ with plain old Rasbian Stretch. I'll be putting a howto up on GitHub soon.
