A Robot's Imagined Corridor Still Needs a Collision Check
HorizonNav turns one image into possible surrounding space, then tests whether a planner can use that reconstruction.

Summary
HorizonNav turns one image into possible surrounding space, then tests whether a planner can use that reconstruction.
HorizonNav combines video generation, camera-pose estimation and depth alignment to build a plausible 3D environment from one image and a text prompt. Its authors report improved planning feasibility as the imagined horizon expands. They also expose the failure cases: six of 25 evaluated generated-camera trajectories violated reconstructed collision constraints, and a planner recovered alternatives in five. These are experiments in reconstructed, imagined environments. The result highlights a useful distinction for navigation research: coherent-looking generated video still needs geometric checks before it becomes a path a robot can follow.
Why it matters
HorizonNav turns one image into possible surrounding space, then tests whether a planner can use that reconstruction.
