首发时间:2013-12-11
摘要:针对动态测绘技术对移动载体姿态信息获取时效性、可靠性以及操作便捷性需求日益扩大的趋势,结合惯性技术最新发展势态,设计了基于Mti-g微惯性航姿的数据采集、处理与显示系统。提出利用Microsoft Foundation Classes(MFC)实时串口通信技术中的MSComm控件完成对Mti-g数据的实时采集;采用四元数法更新惯导系统中的捷联矩阵,以此完成对载体姿态角的解算;结合Open Graphics Library(OPENGL)图形编辑技术的优势,完成了载体姿态解算数据的提取、二维实时曲线、三维动态的显示功能。最后利用试验结果验证本软件设计的合理可行性。

Data collection and display system design of micro-AHRS based on Mti-g
Abstract:IIn view of the trend of the demand of Dynamic mapping technology for mobile carrier attitude information timeliness,reliability and operating convenience,combined with the latest developments of inertial technology,Designed position data acquisition,processing and display system based on the Mti-g micro inertial navigation,Put forward use the MSComm control which belongs to Microsoft Foundation Classes (MFC) serial communication real-time technology to Complete acquisition the Mti - g data real-time,The quaternion method is adopted to update the strapdown inertial navigation system matrix,In order to complete the calculation of carrier attitude Angle,Combining the advantage of Open Graphics Library(OPENGL)Graphics editor technology,Completed extraction, two-dimensional curve real-time , the three dimensional dynamic display function of the carrier attitude algorithm of data, Finally the software design is validated with experiment results of reasonable feasibility
