VisionSIM kills the perfect-sensor illusion

🔥 What happened Researchers at the University of Rochester dropped VisionSIM, a simulator that models cameras, LiDAR, event, SPAD, iToF, and thermal sensors down to the raw physical measurement – including the failure modes other simulators sweep under the rug. 💡 Why it matters Idealized sensor data is why robots flop in the real world. VisionSIM reproduces LiDAR pileup, iToF phase wrapping, and event-camera refractory drops, and ships a synchronized indoor dataset with raw measurements and ground truth. ⚡ Our take Training robot perception on clean simulations is building castles in the air. VisionSIM is the reality check the field has been dodging for years.
