“…However, the Kalman filter algorithm, during the process of state estimation, involves recursive calculations and state estimation smoothing, which can sometimes impact the real-time nature of state estimation, causing the covariance to gradually increase over time. To achieve more precise posterior state estimates in post-processing, this study employs the Rauch-Tung-Striebel (RTS) algorithm, leveraging all observation updates to constrain errors and address the fixed-lag smoothing problem [9][10][11][12] . The algorithm flow is shown in Figure 2.…”

Given the time constraints and demanding precision requirements of railway measurements, traditional measurement methods struggle to meet the inspection needs for the future expansion and renovation of extensive rail networks. This paper presents a railway data collection and processing system developed by using mobile laser scanning technology. To address the issue of error accumulation exceeding predefined limits in the positioning algorithm, we conducted a comprehensive study and utilized smoothing algorithms to correct acceleration and attitude angles. This optimization process not only enhances trajectory data but also improves the accuracy of the point cloud. The results indicate that this system holds significant importance in the realms of railway digital survey and design, as well as digital renovation and related areas.
