Fred Man Thanks for your time and patience on this issue.
I have checked on this issue internally and below is an update. Hope this helps.
The Depth Engine algorithm is Microsoft IP, and we currently have no plans to open-source this component. The firmware of Azure Kinect DK is authored by a 3<sup>rd</sup> party (Vendor of the SoC used in AKDK) to requirements provided by Microsoft, I don't think we can open-source this code either. We've licensed our ToF technology to Analog Devices, they have sensors, module and dev kit offerings if someone wants a custom design: 3D Time of Flight (ToF) | Analog Devices Similarly, we've also partnered with Orbbec and they have a camera (available for purchase) using the same ToF Depth module as Azure Kinect DK: Femto Mega - ORBBEC - 3D Vision for a 3D World
Do let us know if you have any further queries.
