I am a complete novice/amateur at computer vision, machine learning, OpenCV, PyCharm, GitHub, etc., and still a novice Python programmer. But I was a professional programmer and electronics engineer for a long time, so I can recognize great hardware and software products and great technical support when I see it. I purchased my OAK-D during its Kickstarter campaign, but only started working with it in April.
So far the OAK-D has done everything promised. I think it is a fabulous piece of technology. DepthAI is also great. Reasonably easy to use and it performs really well on both my MacBook and my Raspberry Pi. And the examples ... the breadth of examples is just stunning!
The Luxonis support team, however, deserves special praise. I've run into all the standard things one finds with new products/technologies: lack of knowledge on then part of the user, missing or inadequate documentation, code bugs. In every instance I've encountered, one or more members of the team stepped up quickly to address the situation and produce a resolution, sometimes while having to in effect hold my hand (remember novice/amateur). They seem to work 24/7. Very, very impressive!
My compliments to Luxonis all around! Makes me look forward to the delivery of my OAK-D Lite.
