| Yes, we can. We can do it with one eye too. but it takes at least 10 years to train. But most of the time we are not building a 3d map from points. we are building it from object inference. There are many advantages that we have over machines: o The eye seens much beter in the dark
o It has a massive dynamic range, allowing us to see both light and dark things
o it moves to where the threat is
o if it's occluded it can move to get a better image
o it has a massive database of objects in context
o each object has a mass, dimension, speed and location it should be seen in None of those are 3d maps, they are all inference, where one can derrive the threat/advantage based on history. We can't make machines do that yet. you are correct that two cameras allows for better 3d pointcloud making in some situations. but a moving single camera is better than a static multiview camera. however even then the 3d map isn't all that great, and has a massive latency compared to lidar. |
