Seeing More With Less: Leveraging Positional Telemetry for V2X Cooperative Perception
Bibliographic record
Abstract
We present a novel fusion algorithm that enhances vehicular perception in Vehicle-to-Everything (V2X) networks. Traditional fusion methods face significant implementation challenges since these networks have limited available bandwidth for data transmission. Although intermediate-layer processing reduces overall message size, compatibility is often limited to vehicles operating under application-or platform-specific standardization. Due to these transmission and implementation issues, we have developed a novel system that uses raw-level positional telemetry data to generate global perception maps. We combine data pipelines and transformation matrices with Kalman Filtering techniques to generate a dynamic, unified representation of a multi-vehicle environment. Our algorithm increases detection precision by over 21 percent for the overall perception system and by over 59 percent when measured on a median-per-grid basis across various detection scenes and network delays for different sample sizes. This mechanism permits the efficient transmission of essential information while maintaining the integrity of perception and tracking processes. We improve upon existing methodologies in multi-vehicle environments and complex traffic scenarios by enhancing performance under challenging network conditions. Our work provides foundational support for systems related to cooperative perception, autonomous driving, and safety-critical maneuvering by enabling robust data fusion. This is essential for developing vehicular autonomy at scale and supporting network operations for ground-level V2X infrastructure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
