[Question] How to enable Neural Depth Sensing for ZED2? #563

Closed hyylx94 closed 4 years ago

hyylx94 commented 4 years ago

Hi,

I'm using both ZED mini and ZED2. The ZED SDK I installed is 3.0.1 and I used ROS melodic. From the website, I know ZED mini uses stereo depth sensing while ZED2 uses neural stereo depth sensing technology. I would like to know is there any parameter I need to set to switch between these two depth sensing algorithms? Or it will automatically enable neural stereo depth sensing when I set "camera_model:=zed2"?

Thanks in advance!

Kind regards, Xin

Neural stereo depth sensing is automatically enabled by the SDK using "ULTRA" mode for depth

hyylx94 commented 4 years ago

Thanks for your reply! Then what about ZED mini? If I use ZED mini and set "ULTRA" mode for depth, only normal stereo depth sensing is enabled right?

Myzhar commented 4 years ago

No, it's available for all the Stereolabs camera models. Only the object detection module is an exclusive of the new ZED2

Thanks! One more question about enable "ULTRA" mode, shall I set "3" or "4"?
In file "param/common.yaml", it seems that I need to set "3": image In the parameter document, it seems that I need to set "4": image

@hyylx94 3 is correct. Thank you for reporting that the online documentation must be updated :+1:
