For as long as machines have learned to see, they have struggled to truly know where they stand — recognizing a thing is not the same as understanding its place in the world. Researchers have now married two mature disciplines of computer vision, fusing three-dimensional spatial reconstruction with enhanced object detection to give autonomous systems not just perception, but location. The work arrives at a moment when drones, self-driving vehicles, and intelligent infrastructure demand more than a label on a screen — they require the kind of grounded spatial awareness that allows action, not m
