Problems solved by technology

The above method can realize that there are mileage piles on the collection site, and it is impossible to collect without mileage piles. However, various roads, due to historical reasons and traffic accidents, may cause mileage piles to be missing. construction, it may also cause mileage piles to be blocked, making it impossible to collect

Embodiment Construction

[0038] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

The invention discloses a missing mileage pile automatic generation method and device. The missing mileage pile automatic generation method comprises automatically acquiring information of existing mileage piles on a road; after acquiring mileage pile information of two adjacent mileage piles, calculating the distance between the two acquired adjacent mileage piles, determining whether the distance between the two adjacent mileage piles exceeds a set pile spacing and / or the pile numbers or mileage of the two adjacent mileage piles are / is continuous; and adding the missing mileage pile in dependence on the distance between the two adjacent mileage piles when the distance exceeds the set pile spacing and / or the pile numbers or mileage are / is not continuous. By employing the missing mileage pile automatic generation method and device, information of the missing mileage pile can be automatically acquired, and data of the missing mileage pile can be automatically acquired to the road complementally.

Description

technical field [0001] The present application relates to the field of map information collection, and in particular, relates to a method and device for automatically generating missing mileage piles. Background technique [0002] With the development of Internet technology, Internet navigation has become a common tool for people to travel. Both Internet navigation and stand-alone navigation should rely on accurate road information. An important piece of information in the road information is milepost information on the road. In the prior art, the automatic acquisition equipment and the acquisition method of road surface conditions are as follows: through the CCD camera and the vehicle speed detection circuit to detect the vehicle speed, the acquisition matching control circuit dynamically adjusts the trigger pulse according to the vehicle speed information provided by the vehicle speed detection circuit, and controls the CCD camera to shoot Action, to achieve a certain ra...
