A method and system for supervising highway signs

Abstract

A method and system for supervising highway signs, the method includes: firstly, establishing a preprocessing standard model by labeling a single sequence from existing highway standard GPS and image data; secondly, obtaining the latest real-time GPS and Image data, establish a real-time model by annotating double sequences; then, compare the real-time model data with the standard model data through double-sequence matching search, and match the real-time best image obtained from the real-time model with the standard image in the standard model. ; Further, use the image matching algorithm to compare the standard model image data to determine the specific type of identification damage; finally, update the standard model according to the identification result and maintenance status. According to the internal relationship between the position of the road sign and the image, the invention periodically collects, automatically identifies and locates the damage of the road sign and its type, thereby improving the detection efficiency of road assets and reducing the maintenance workload.

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...

Problems solved by technology

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 replaced in time, which will affect the specification, appearance and safety index of the road, and have a negative impact on people's travel instructions; in addition, due to human judgment Differences can easily lead to problems such as inconsistent standards

It is self-evident that the integrity of the road signs on the expressway is important to the safe driving of drivers. For example, the lack of road signs on the expressway can easily lead to serious traffic accidents such as speeding of high-speed vehicles; The long distance of the road and the excessive speed of the vehicle will also affect the working efficiency of the staff, and more importantly, it will also endanger the safety of the staff
