Embodiment Construction
[0020] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.
[0021] see figure 1 , the embodiment includes the following steps:
[0022] S11: sequentially read multiple data items in the chainage sequence;
[0023] Among the data items of the datum chainage sequence, one calibration data item is sequentially read;
[0024] Wherein, among all the data items of the reference chainage sequence, some data items are used as the calibration data items, and the geographical position data of each calibration data item is the geographical position data of a mileage chainage; each of the data The items include: the detected stake number and the geographic location data corresponding to the detected stake number;
[0025] S12: Determine the distance between each data item and the calibration data item by using the geographic location data of the p...

The invention discloses a method for calibrating detection stake number based on mileage stake number. The method comprises the following steps of: orderly reading multiple data items in a stake number sequence; orderly reading one calibration data item in the data items of a reference stake number sequence; determining the distance between each data item and the calibration data item according to the geographical position data of the data items and the geographical position of the calibration data item; comparing among the determined multiple distances to get the data item corresponding to the minimum distance, wherein the distances determined with the front and back neighboring data items of the data item are all greater than the minimum distance; and correcting the detection stake number of the data item corresponding to the minimum distance with the detection stake number of the calibration data item. In the method, the geographical position data of some detection stake numbers of the reference stake number sequence is the same as the geographical position data of the mileage stake number, after calibrating the detection stake number of the stake number sequence by the detection stake number of the reference stake number sequence, the road condition data corresponding to the detection stake number can be used comprehensively, and an accurate result can be obtained.
Description
technical field [0001] The invention relates to the field of automatic processing of highway maintenance data, in particular to a method for calibrating and detecting stake numbers based on mileage stake numbers. Background technique [0002] In the process of road inspection and maintenance, it is necessary to determine the exact position on the road surface. While determining the position, determine the road surface data detected at the position, such as the damage rate and the elevation data of the longitudinal section. [0003] Since the detection of the road surface involves a variety of data, these data are not completed in the same drive test, but need to be carried out separately through multiple drive tests. During the drive test, the stake number will be used as the identification of the road surface position, and the data detected at the stake number position will be recorded during the drive test. [0004] At present, mileposts built on the roadside are used on ...
