Supervising method and system of way mark

Abstract

The invention discloses a supervising method and system of a way mark. The method includes the steps of establishing a preprocessing standard model through a mark single-sequence mode according to a known way standard GPS and image data, obtaining the latest real-time GPS and image data through inspection operation, establishing a real-time model through a mark double-sequence mode, comparing real-time model data with standard model data through double-sequence matching search, matching the real-time optimal image obtained in the real-time model with the standard image in the standard model, comparing standard model image data through an image matching algorithm, determining the specific type of identification damage, renewing the standard model according to the recognition result and the maintenance state. According to the way identification position and the relationship between the images, the damage and type of the way mark are collected periodically in real time and recognized and positioned automatically, the way asset detection efficiency is improved, and the maintenance workloads are reduced.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to a method and a system for supervising road signs by using an information system. Background technique [0002] As one of the basic constructions, roads are an important part of public assets. After road construction is completed, real-time supervision and maintenance are required to ensure the normal use of roads. At the same time, real-time supervision and maintenance are also one of the most basic means to protect road assets. At present, the systems used for road supervision and maintenance mainly include pavement management system and bridge management system, etc., and these systems are only used to detect and maintain the geology and road surface, and cannot realize the supervision of road signs. [0003] Highway signs are usually set on both sides of the highway or on the top of the highway. When monitoring them, staff need to collect and input data on the sp...

At present, the systems used for road supervision and maintenance mainly include road surface management system and bridge management system, etc., and these systems are only used to detect and maintain the geology and road surface, and cannot realize the supervision of road signs

[0003] Highway signs are usually set on both sides of the highway or on the top of the highway. When monitoring them, staff need to collect and input data on the spot along the way, which not only consumes a lot of manpower, material resources, time and resources, but is prone to missed inspections and missing records. , and because the detection cycle takes a long time, the damaged road signs will not be found and re...
