Automotive In-Vehicle Vision Recognition POC

📋 Project Overview

We collaborated with a major automotive manufacturer's research lab on a proof-of-concept project to validate the feasibility of in-vehicle camera-based intelligent recognition. The goal was to enable smart alerts for scenarios such as forgotten items or children left in the back seat. Through this experimental project, we validated that our locally-deployed multimodal vision model could accurately recognize various objects across different environments with low latency, and confirmed its capability for single-chip deployment—providing valuable technical validation for the manufacturer's future product roadmap.
