InvenSense陀螺仪姿态解算，直接输出四元数，省去姿态融合算法的编写，适用于飞控(The attitude calculation of InvenSense gyroscope outputs four elements directly, and avoids the compilation of attitude fusion algorithm, which is suitable for flight control)

本设计是基于STM32F4的四轴航拍平台。以STM32F407为控制核心，四轴飞行器为载体，辅以云台的航拍系统。硬件上由飞控电路，电源管理，通信模块，动力系统，机架，云台伺服系统组成。算法上采用简洁稳定的四元数加互补滤波作为姿态解算算法，PID作为控制器，实现飞行，云台增稳等功能。具有灵活轻盈，延展性，适应性强好等特点。(This design is based on STM32F4's four axis aerial platform. Taking STM32F407 as the con
