Lamdmarks accuracy issues

silviu_z_ — Thu, 10 Mar 2016 11:56:28 GMT

Hi,

I am using SR300 face detection and tracking. In my application it's important to have accurate 3D position. The landmark positions in space are usually short by 2-4cm (SDK r5). I had some experience with the F200 system with SDK r4, and there the results were much better typically +-0.5cm. I tried also the r6 SDK but there the deviations were even larger.

Any ideas? Is it a camera calibration issue?

Thanks, Silviu.

You can definitely improve the depth resolution doing a more accurate calibration with your specific camera.

Hi samontab,

Hi samontab,

Thanks, that's what I intend to do. I hoped that the factory calibration would be more accurate (one system has 10cm deviation at 50cm distance), but probably that's what you can get for a 100USD camera.

Thanks, Silviu.
