If you only meant that the passive system described by the person you were responding too had too high a latency then I think we are in agreement.

However, regarding binocular versus LIDAR in general, I would say that while a greeter frequency is always better 15 Hz should be fine. And in fact the awesome $70,000 LIDAR used by Google's self driving car only runs at 15 Hz.
