【摘要】 研究基于数字高稳定航拍系统,实现在相对噪声环境不佳的外界环境下实现高质量拍摄有着重要研究意义。本文在总体设计的角度出发,着重研究航拍时产生噪声原因并通过数学计算方法,将影响航拍稳定的噪声因素通过软件算法和伺服系统将抖动有效最低,并通过设计一套具有智能控制自主稳定的主动降噪陀螺仪稳定云台及软件算法使速度环与角度环闭环,以实现高稳定航拍。航拍UAV-Cam射频通信技术通链路研究,为低空高稳定航拍提供理论依据。文中阐述了普便使用陀螺仪和力矩电机闭环稳定平台基础上,以轻型结构制作稳定平台框架结构设计,充分考虑了自稳台转体的质量、半径、体积等分布情况对动静单发直升机平台震动特性的影响。针对不同结构和材料对稳台摄录图像采集进行分析和理论研究,并着重对多自由度转台进行软件算法研究,减少外在硬件处理降噪问题的复杂度和外围电路的复杂度。更多还原

【Abstract】 Based on digital aerial system of high stability UAV-cam. Achieved in a relatively weak external noise environment of high quality film has an important significance.In this paper, the perspective of the overall’design, and focused on the noise generated when the reasons for aerial and through mathematical calculation. It will affect the stability of the noise factor in aerial photography software algorithms and servo systems will shake the effective minimum. To designing a set of autonomous intelligent control and stability of active noise reduction gyro-stabilized head and software algorithms to enable the speed and angle ring ring loop, in order to achieve high stability and aerial photography. Consideration to the quality of self-stabilized units swivel radius, volume, distribution of the static single vibration characteristics of a helicopter platform.Different structures and materials on the stability of Taiwan video image acquisition analysis and theoretical study. Focus on the multiple degrees of freedom for software algorithm turntable to reduce the external hardware processing and noise reduction of complexity and the complexity of the external circuit.更多还原
