Sim-to-Rerun: Using Rerun to visualize CARLA simulator output through #ROS 2. This example visualizes simulated sensor data from the CARLA simulator for autonomous driving in Rerun. It’s built using Rerun’s new proof-of-concept C++ ROS2 bridge, which currently has support for a

Thanks for sharing Dmytro Mishkin 🇺🇦 It's actually none or multiple fields per keyframe. Depending on how much in a new keyframe is not covered by the existing fields yet. Will share a few more details once I'm back from IROS 🙂

Vista is a generative driving world model by Gao et al. Built on Stable Video Diffusion, it can generate driving scenes conditioned on a single input image and optional, additional control inputs. In this example, we visualize the latent diffusion steps and the generated, decoded

I increasingly think OpenAI is trying to destroy the concept of copyright through desensitization. Copyright is a huge threat to their profits. They are facing multiple massive copyright lawsuits. So they release Sora, knowing it can output copyrighted IP and knowing people

Bruns et al., "ACE-G: Improving Generalization of Scene Coordinate Regression Through Query Pre-Training" Train a scene coordinate regressor with "map codes" (ie, trainable inputs) so that you can train one generalizable regressor. Then, find these "map codes" to localize.
