User set configuration as default for Realsense D400 cameras

[Raulval82]

Hi,

Is it possible to make the Realsense D400 cameras to store a custom configuration in any way? I know that you can modify almost any parameter using the sdk, or load a .json with the configuration that you want, but usually the cameras have a user set configurations that you can modify and put as a default, so you can preconfigure the camera and move it to other PC without the need to share any .json file at all. Is this possible?

Thank you in advance.

Hi @Raulval82 RealSense cameras cannot store a configuration within the camera hardware, unfortunately.

Ok, thank you.

@MartyG-RealSense related question,
Can I get a Realsense intrinsics matrix of a specific Realsense model, without connecting a camera?
preferably, in python.

[MartyG-RealSense]

Hi @DaphnaNanovel The intrinsics are stored in the camera, and each camera has a unique set of default intrinsic values that are determined during the manufacturing process in the factory. So the camera needs to be connected in order to access them.

I could provide a list of intrinsics for a particular model from one of my own cameras, though it wouldn't be a precise match to the intrinsics of the camera unit that you own.

Ok thanks. I'm trying to create a debugging environment. where I test my algorithm based on recorded data. If I understand correctly, I need to do it "hard coded".

[MartyG-RealSense]

Yes, if you have not got a physical camera attached then hard-code the intrinsics. An example of doing this is provided by the RealSense SDK's software-device interface for defining a virtual camera.
