Core Concepts
A novel vision chip, Tianmouc, employs a complementary sensing paradigm inspired by the human visual system to enable accurate, fast, and adaptive perception in diverse and unpredictable open-world scenarios.
Abstract
The content presents a novel vision chip called Tianmouc that addresses the challenges faced by traditional image sensors in dealing with dynamic, diverse, and unpredictable scenes in open-world applications. The key insights are:
The vision chip is inspired by the human visual system, which parses visual information into primitive-based representations and assembles these primitives into two complementary pathways: a cognition-oriented pathway for accurate cognition and an action-oriented pathway for rapid response.
Tianmouc incorporates a hybrid pixel array and a parallel-and-heterogeneous readout architecture to realize this complementary sensing paradigm. This allows it to achieve high-speed sensing of up to 10,000 fps, a dynamic range of 130 dB, and advanced spatial resolution, speed, and dynamic range performance.
Tianmouc also adaptively reduces bandwidth by 90%, making it suitable for diverse open-world applications. The authors demonstrate the integration of Tianmouc into an autonomous driving system, showcasing its abilities to enable accurate, fast, and robust perception, even in challenging corner cases on open roads.
The primitive-based complementary sensing paradigm helps overcome fundamental limitations in developing vision systems for diverse open-world applications, where traditional image sensors face substantial challenges.
