摘要
为及时掌握轨道交通线路全断面尺寸及发展趋势,提出了融合激光扫描测量和高精度惯性基准测量技术的车载式全断面检测系统方案.详细分析了如何利用车体运动模型和卡尔曼滤波算法建立精确的动态测量基准,对振动误差进行补偿,并借助数学仿真讨论了方案的可行性.
To monitor the status and the trend of railway complete profile, this paper proposes a new scheme of vehicular measurement system for railway complete profile, by combining laser scanning technique and high-accuracy inertial measurement technique. The kinematical measurement reference is established by utilizing the vehicle dynamical model and Kalman filter to compensate errors invoked by vehicle vibrations. The detailed numerical simulations are also provided to show the feasibility of this scheme.
