Is there a remedy for interference between multiple RealSense devices?

[Anastasia_T_]

Hello everyone,

I would like to use several RealSense sensors and the same time to obtain a 360 degrees view of an object. As expected, two RealSense cameras interfere and the quality of the depth image significantly degrades.
Is it possible to pragmatically change the modulation frequency, introduce time multiplexing or do anything else to avoid the interference?

If not, is it possible to order a pair of RealSense devices that are tuned by the manifacturer so that they do not interfere with each other?

Thank you in advance,
Anastasia

Hi, the IR projector (camera) can be moved so that the projected area does not overlap with the other cameras.

You can also try using a different pattern setting, but this probably will not work.

The technology used in these cameras does not allow you to have multiple cameras looking at the same object from different points of view, as they emit IR patterns to it.

Thanks a lot for your reply. Could you please explain how to use a different pattern setting? I would like to try that. I could not find this in the SDK.

Sure,

You can select from 3 different predefined patterns from the SDK. You can change it by changing the Accuracy parameter of the IR projector. Here is a link to the SDK documentation about this:

Take a look here to get a more detailed explanation on how the camera works:
