Idea
A collaborative perception framework enabling heterogeneous autonomous vehicles to adapt models dynamically during inference for improved sensing accuracy.
Research Paper
Core Innovation
This paper introduces PHCP, a framework that treats heterogeneous collaborative perception as a few-shot unsupervised domain adaptation problem. Unlike prior methods requiring joint training or labeled data, PHCP dynamically self-trains an adapter during inference to align features across different vehicle models. This approach enables real-time adaptation without pre-stored models or extensive retraining.
Market Size (TAM)
$2–10B TAM, $1–2B SAM; assumption: growing autonomous vehicle market and increasing demand for collaborative perception solutions across heterogeneous fleets.

Research Paper Overview
You Share Beliefs, I Adapt: Progressive Heterogeneous Collaborative Perception
Summary
Collaborative perception allows vehicles to share information to overcome individual sensing limits. This paper addresses the challenge of heterogeneous models across vehicles without requiring joint training or labeled data. The proposed Progressive Heterogeneous Collaborative Perception (PHCP) framework performs few-shot unsupervised domain adaptation by self-training an adapter during inference, dynamically aligning features. Experiments on the OPV2V dataset show PHCP matches state-of-the-art performance using only small amounts of unlabeled data.
