# Co3SOP: A Synthetic Benchmark for Collaborative 3D Semantic Occupancy Prediction in V2X Autonomous Driving

[**Paper**](https://huggingface.co/papers/2506.17004) | [**GitHub**](https://github.com/tlab-wide/Co3SOP)

Co3SOP is a high-resolution synthetic benchmark designed for **Collaborative 3D Semantic Occupancy Prediction** in V2X-enabled autonomous driving. 

While single-vehicle perception is often limited by occlusions, restricted sensor range, and narrow viewpoints, Co3SOP facilitates research into collaborative perception. The dataset provides dense and comprehensive occupancy annotations generated using a high-resolution semantic voxel sensor in the CARLA simulator, replaying existing collaborative perception scenarios.

## Dataset Features
- **High-Resolution Annotations:** Provides a voxel-level representation of both geometric details and semantic categories.
- **V2X Scenarios:** Enables the exchange of information between multiple agents to enhance perception accuracy.
- **Diverse Prediction Ranges:** Establishes benchmarks with varying spatial extents (25.6m, 51.2m, and 76.8m) to assess the impact of range on collaborative prediction.
