"maps/ photos look nothing alike, making correlating by AI difficult, overcome with dataset of 90K pairs floor plans/ photos (manually aligned) across nearly 600 internet photos turned into 3D models... includes 153 million pixel-level matches, allowing AI to see spot in photo corresponding to map coordinate... reduces errors by 34%... step toward multi-modal 3D computer vision... robots navigating indoor spaces using only blueprint, AR helping people find way through buildings, digital modeling: 3D architecture reconstructions"
