A New Filtering and Smoothing Algorithm for Railway Track Surveying Based on Landmark and IMU/Odometer

High-accuracy railway track surveying is essential for railway construction and maintenance. The traditional approaches based on total station equipment are not efficient enough since high precision surveying frequently needs static measurements. This paper proposes a new filtering and smoothing alg...
