Evolution gave humans, and most all other mammals, two eyes. Human eyes are typically spaced 6 to 7 centimeters (2.4 to 2.8 inches) apart. Remarkably, a substantial portion of the human brain is dedicated to processing visual information, with some studies suggesting a significant investment of the brain's resources in this area (source: University of Rochester). Our brain is able to perceive both how close an object is from us and where that object is heading. When Luxonis set out to create an edge artificial intelligence (AI) depth camera, we used learnings from human eye sight to design our products. This is why the stereo baselines of our cameras are typically 7.5 centimeters (3 inches) apart and a sizable portion of our onboard processing is dedicated towards fusing the left and right cameras together to create a three dimensional map.

At Luxonis, we are on a long term mission of empowering companies to surpass human perception in every task. To achieve that mission, it requires the accuracy of the depth map to be superior to humans. Fortunately, we have already long since exceeded this because human beings are actually quite poor at estimating distances. If you look at your hands do you really know if they are currently 10, 12, or 14 inches away from your head? There is a reason we all have a tape measure (or laser or smartphone) at home to help us determine distances.
We have recently been working diligently to improve the accuracy of our depth maps. And we are now proud to announce that starting in March 2024, stereo cameras shipped from Luxonis will be implemented with a next generation calibration procedure that delivers much better accuracy than our old generation. Please note that fortunately the performance is not hardware limited so existing devices can be recalibrated.
Here are the real world (not theoretical) depth accuracy measurements that you’ll be experiencing with our products come March:
0.7m - 4m (2’4” to 13’1”): below 2% absolute depth error
4m - 7m (13’1” to 23’): below 4% absolute depth error
7m - 12m (23’ to 39’4”): below 6% absolute depth error

If you’d like to get your hands on an OAK with improved depth sooner please reach out to us at [support@luxonis.com](mailto:support@luxonis.com).
We'll be releasing competitive benchmark data on depth performance by the end of March.
