What is the range of Intel Realsense vision?

[René_V_]

I couldn't find this anywhere, so I hope this is the right place to ask:

Untill how far back do the features of intel realsense work?

Specifically: Say I connect my laptop to a large TV screen, and say I position the Create Camera for developers in an optimal place.
If I stand 3 meters away from the camera, would it still be able to do hand detection and face recognition?

(I meant the Intel® RealSense™ Developer Kit camera from Creative)

It has a limited range. For the camera, 1m is far away, as you can see from the docs, in the section about SetIVCAMFilterOption. This is the suggested setting for far away objects:

7       Very far range       Very high smoothing effect to bring moderate accuracy level for distances above 1000mm. Use together with the MotionRangeTradeOff property to increase the depth range.

The farther away, the worse it performs. I don't think it would detect it at 3m, no way.

thanks!

You can get it to _really_ far range (i'm talking 5 meters!), by selecting

SetDepthConfidenceThreshold(0);
SetIVCAMLaserPower(16);
SetIVCAMAccuracy(PXCCapture::Device::IVCAM_ACCURACY_FINEST);
SetIVCAMMotionRangeTradeOff(100);
SetIVCAMFilterOption(1);

The fps will be very low, like 5, but you can use it to 3D scan a room for example.

that's very useful info, tnx Zsolt!

always good to know how stretch the technology to it's boundaries for the rare cases you really want to :)

Sure Zsolt, but that's just raw 3d data. He asked for the SDK features, such as hand tracking. They have more requirements than just raw data, they need to have a fast refresh rate.

Can these parameters be accessed in Unity. Which would be the relevant scripts
