Tool to significantly improve the depth map accuracy of RealSense cameras open-sourced on GitHub

MCalv4 — Sat, 03 Nov 2018 14:04:01 GMT

The accuracy of depth maps can be greatly improved by calibrating all the intrinsic and extrinsic parameters, along with non-linearity correction as a single problem.

Here is the accuracy of an out-of-the-box D435 compared to the results after optimisation:

The original quadratic error becomes almost linear in the depth, an order of magnitude better at 2.5 metres.

The VS2017 solution is open-sourced, Apache 2.0 on GitHub https://github.com/smirkingman/RealSense-Calibrator https://github.com/smirkingman/RealSense-Calibrator.

As I own only a pair of D435s, I would be very grateful if those with other cameras could let me know if they achieve similar results.

Thanks,

Looks great! Thanks so much for your hard work.

Could you post this on the RealSense GitHub too please so the RealSense developers and engineers there can evaluate it?

You may also like to consider submitting a 'pull request' for your project to be integrated into the SDK. This is optional but would be welcomed.

Hi Marty

I've never used GitHub and I'm floundering trying to post as you suggest, 'Authorise mabako' is greyed out:

Could you possibly contact me privately, to avoid spamming the forum with my ineptness please?

Alternatively, is there a kind GitHub wizard who could post for me?

Thanks
