Problems solved by technology

If the actual chainage information of the damaged position is directly sent to the road maintenance personnel, the road maintenance personnel will search for the damaged position according to the displayed chainage information of the mileage chainage on the roadside. If the actual chainage information is corrected to display the chainage information, the road maintenance personnel will not be able to find the damaged location when the displayed chainage information of the roadside mileage chainage is K0+900 according to the actual chainage information K0+900, affecting road maintenance efficiency

Embodiment 1

[0032] See figure 1 , The embodiment of the present invention provides a method for automatically calibrating mileage number, including the following steps:

[0033] 100. Take a photo of the roadside scene every fixed driving distance to obtain a picture of the roadside scene;

[0034] 200. Number all the roadside scene pictures in the order of taking pictures;

[0035] 300. Extract the station number display picture containing the actual station number information of the mileage station number from the numbered roadside scene picture;

[0036] 400. Obtain the actual distance of the mileage station number according to the number difference between any two of the station number display pictures and the fixed driving distance;

[0037] 500. Obtain the displayed distance of the mileage station number according to the difference between the displayed station number information of the mileage station number in the two arbitrary station number display pictures;

[0038] 600. Obtain a correctio...

Embodiment 2

[0043] At the same time, see again figure 1 , The embodiment of the present invention provides a method for automatically calibrating mileage number, including the following steps:

[0044] 100. Take a photo of the roadside scene every fixed driving distance to obtain a picture of the roadside scene;

[0045] 200. Number all the roadside scene pictures in the order of taking pictures;

[0046] 300. Extract the station number display picture containing the actual station number information of the mileage station number from the numbered roadside scene picture;

[0047] 400. Extract the station number display picture containing the actual station number information of the mileage station number from the numbered roadside scene picture;

[0048] 500. Obtain the displayed distance of the mileage station number according to the difference between the displayed station number information of the mileage station number in the two arbitrary station number display pictures;

[0049] 600. Obtain a ...

Embodiment 3

[0068] Correspondingly, the third embodiment of the present invention provides an automatic mileage correction system, see figure 2 ,include:

[0069] Take a picture of the roadside scene every fixed driving distance to obtain the photographing component 10 of the roadside scene picture;

[0070] A numbered component 20 that numbers all the roadside scene pictures in the order of taking pictures;

[0071] Extracting from the numbered roadside scene pictures the image processing component 30 of the station number display picture containing the actual station number information of the mileage station number;

[0072] According to the difference between the numbers of any two of the station number display pictures and the fixed driving distance to obtain the actual distance of the mileage station number; and then according to the any two station number display pictures, one of the displayed station number information of the mileage station number If difference, the displayed distance o...

Abstract

The invention relates to the field of pavement monitoring, and in particular relates to an automatic mileage stake mark calibration method, system and method. The method comprises the steps of photographing roadside scenes every other fixed travelling distance to obtain roadside scene images; numbering all roadside scene images according to a photographing sequence; extracting stake mark display images containing actual stake mark information of mileage stake marks from the numbered roadside scene images; obtaining an actual distance between the mileage stake marks according to numbering difference between any two stake mark display images and the fixed travelling distance; obtaining a display distance between the mileage stake marks according to display stake mark information difference (of the mileage stake marks) of any two stake mark displaying images; and obtaining a calibration coefficient according to the ratio of the actual distance to the display distance, thus obtaining the display stake mark information of the mileage stake marks corresponding to the actual stake marks of the mileage stake marks in each stake mark display image. The method can be used for calibrating the actual stake mark information into the display stake mark information of the mileage stake marks, so that the road maintenance efficiency is improved.

Description

Technical field [0001] The invention relates to the field of road surface monitoring, in particular to a method, system and device for automatically correcting mileage and stake number. Background technique [0002] With the rapid development of transportation in our country, accurate location of highway damage can improve the efficiency of road maintenance and reduce the incidence of highway traffic accidents. [0003] At present, the location of the damaged position of the expressway usually uses sensors installed on the wheels. For example, the sensor detects that the damaged position is at the position where the actual station number information is K0+900; however, the station number information is often displayed due to the mileage of the highway roadside. There is an error with the actual station number information. For example, the displayed station information of the two mileage station numbers are K1 and K2 respectively, which means that the displayed distance of the two m...
