When a crew searches a damaged building, the layout, the rooms already cleared and the people found all live in someone’s head. SweepMap turns an iPhone Pro into a live search map. As you walk, LiDAR and Apple RoomPlan draw the floor plan and a trail of where you’ve already searched. Every 1.5 seconds a camera frame goes to SAM 3.1, and each person it finds becomes a pin placed in 3D using the depth and camera position from that exact frame, so it lands where the person really is. Every detection keeps the image SAM saw, so a responder confirms or dismisses it with one tap, and it floats as an AR marker at the person’s position. Hold-to-talk voice notes go on the map hands-free, one tap shows the route back out, and another shares the floor plan and a timestamped report with the next team.
