MODERATORS
You misunderstand. I never said they can calculate distance. They just don't measure it, it's inferred. Inferring results in unreliable estimates. The unreliability of which is not accounted for appropriately in camera based autonomy systems.
It's not an issue in astronomy. Because people can examine the results further and discount any clearly incorrect distance calculations.
It's not just about not seeing anything. Outdoors is one of the most variable and challenging lighting conditions for most systems. Too much light, shadows, etc.
You only need one frequency of light for camera based distance measurements. They require features rather than a specific light.
Your security camera does not operate in pitch black. It has infra red lights that illuminated the scene, you just can see it. Your security cameras are subject to problems in both high and low light conditions. It can make adjustments throughout the day to compensate for changing light. However it doesn't make it measure distance.
