The invention discloses a detection vehicle position predicting method and device. The detection vehicle position predicting method includes the following steps that: the historical state quantity andhistorical measurement quantity of a detection vehicle are determined based on the historical measurement information and preset information of the detected vehicle; the historical state quantity ofthe detection vehicle is inputted into to a preset attitude angle prediction model, so that the predicted attitude information of the detection vehicle is obtained; and the predicted position information of the detection vehicle is determined according to the predicted position odometer speed of the detection vehicle and the predicted attitude information of the detection vehicle. With the detection vehicle position predicting method adopted, the problem of difficulty in inertial navigation error correction in the prior art can be solved; inertial navigation errors can be conveniently and effectively corrected; and structural simplicity and high measurement efficiency can be realized.
Description
technical field [0001] The present application relates to the field of measurement, in particular, to a method and device for predicting the position of a detection vehicle. Background technique [0002] At present, most track inspection vehicles use inertial navigation. Based on inertial navigation, track inspection vehicles can provide high-precision, fast and continuous track parameter measurement. However, inertial navigation also has disadvantages. After a long period of uninterrupted work, inertial navigation will produce cumulative errors, which will lead to inaccurate calculation of the attitude and position of the track inspection vehicle. [0003] In order to solve the problem of cumulative error of inertial navigation, the current solution mainly relies on GPS or total station to correct the error of inertial navigation, but the measurement accuracy of GPS is low, which cannot meet the needs of high-precision measurement of track inspection vehicles. However, sta...
