Astra 2 starting depth point (Z=0)

I have an Astra 2 I’m using to create depth maps, and I couldn’t find the zero depth point of the camera on the datasheet or even online, does anyone have this information?

I’m assuming it’s the front of the IR sensor, but how far is that exactly from the front glass? Or I am wrong in assuming that, and is it simply set to the front glass?

You could contact Orbbec team to confirm. info@orbbec3d.com

Thanks for the tip, I’ve just contacted them. We’ll see what they respond.
