随着智能交互技术的迭代升级，传统汽车尾门开启方式已难以满足用户对便捷性与科技感的双重需求。为实现无接触式智能操作体验，本研究创新性地将增强现实（AR）光影技术深度融入汽车尾门控制系统，开发出一套基于 AR 光影识别的自动电尾门解决方案。该系统搭载高精度动作捕捉与投影交互模块，能够精准识别用户的踩踏动作指令 —— 当用户脚部进入预设投影区域时，系统将立即触发尾门自动开启功能，彻底解放双手操作束缚，为用户带来极具未来感的智能交互体验。

With the iterative upgrading of intelligent interaction technology, the traditional way of opening car tailgates has become difficult to meet users' dual demands for convenience and a sense of technology. To achieve a contactless intelligent operation experience, this study innovatively integrates augmented reality (AR) light and shadow technology deeply into the automotive tailgate control system, and develops an automatic electric tailgate solution based on AR light and shadow recognition. This system is equipped with a high-precision motion capture and projection interaction module, which can accurately identify the user's stepping action instructions. When the user's feet enter the preset projection area, the system will immediately trigger the automatic opening function of the tailgate, completely freeing the user from the constraints of manual operation and providing a highly futuristic intelligent interaction experience.
