Abstract
With its fast, smooth and comfortable riding environment, high-speed rail has become the preferred travel tool for people. In order to guarantee the safe operation of high-speed railway, the geometrical state of high-speed railway must be tested. However, the existing detection methods and equipment are slow to measure, which can not meet the requirements of daily operation or maintenance of high-speed railway. For this purpose, this paper proposes a fast measurement method based on relative measurement and absolute measurement, which solves the problem of slow speed of external geometry parameters of the existing rail inspection equipment.
