With the rapid advancements in autonomous driving, pure vision-based solutions have garnered significant attention. However, existing vision sensors are limited by their specific spectral operating ranges and the complexity of processing hybrid optical/electrical signals. In this study, we present a fully circuit-emulated vision system that employs a vision fusion solution for autonomous driving, integrating image sensing, fusion, edge extraction, and decision-making functionalities. This system utilizes vision sensors featuring an AlO/two-dimensional Ruddlesden-Popper perovskite (2D PVK) heterostructural dielectric and MoS/black phosphorus (BP)/MoS heterostructural channel, which exhibits persistent nonvolatility and fully light-tunable positive and negative photoresponses when exposed to 1064 nm and 532 nm light, respectively. Notably, when combined with edge extraction circuit design, our vision system achieves all-day visual perception with a 99.0% recognition accuracy for driving scenario information. The integration of the fully circuit-emulated vision system with the vision fusion solution enables a more comprehensive and accurate representation of the driving environment.
随着自动驾驶技术的飞速发展,基于纯视觉的解决方案受到了广泛关注。然而,现有的视觉传感器受到其特定光谱工作范围以及处理混合光/电信号复杂性的限制。在本研究中,我们提出了一种全电路仿真视觉系统,该系统采用用于自动驾驶的视觉融合解决方案,集成了图像传感、融合、边缘提取和决策功能。该系统利用具有AlO/二维Ruddlesden-Popper钙钛矿(2D PVK)异质结构电介质和MoS/黑磷(BP)/MoS异质结构通道的视觉传感器,当分别暴露于1064 nm和532 nm光时,该通道表现出持久的非挥发性以及完全光可调的正、负光响应。值得注意的是,当与边缘提取电路设计相结合时,我们的视觉系统实现了全天候视觉感知,对驾驶场景信息的识别准确率达到99.0%。全电路仿真视觉系统与视觉融合解决方案的集成能够更全面、准确地呈现驾驶环境。
