We've had a few weeks to react to feedback and have released six updates since our October 3rd launch. Most of these updates have been bug fixes, but we wanted to bring your attention to the latest update (v0.9.13), which makes camera calibration both easier and more accurate.
We realize camera calibration was a significant pain point for you. As a result, we've rewritten it to consist of just two easy steps:
- Adjust the cameras so that the checkerboard is centered in each image.
- Wave your arms around.
Here's a thirty-second video showing the new calibration:
The best part of this new calibration process is that it's also quite a bit more accurate than before. We urge you to give it a shot! Download the latest version (v0.9.13) from our Download page.
Thanks again for trying out our SDK! We'll keep you posted with more updates!
