A trajectory data verification method and device

Abstract

The invention discloses a trajectory data checking method and device. The trajectory data checking method includes the steps that a position point sequence Sa and a position point sequence Sb to be checked are acquired, wherein the Sa and the Sb are collected through equipment; the Sa and the Sb are sampled according to the same intervals to acquire a sequence Sa' and a sequence Sb'; the position region where the Sa' is located and the position region where the Sb' is located are divided into a plurality of equilong sections; statistics is conducted on the number of position points of the Sa' in each section and the number of position points of the Sb' in each section respectively, and whether the position point sequence Sb to be checked is wrong or not is judged according to the difference between the number of the position points of the Sa' in each section and the number of the position points of the Sb' in each section. Due to the utilization of the technical scheme, automatic checking of manually-input data is achieved, human cost consumption is effectively reduced, and checking efficiency is improved. Meanwhile, complex mathematic calculation is not needed in the whole scheme, and therefore the trajectory data checking method and device are beneficial to being implemented and popularized.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method and device for checking track data. Background technique [0002] Electronic map, also known as digital map, is a map stored and queried digitally using computer technology. Compared with traditional paper maps, the production, management, reading and use of electronic maps can be integrated, which is convenient for real-time modification; using the data query capabilities of computers, electronic maps can achieve faster and more diverse query methods , which is convenient for users to use. In addition, electronic maps can easily combine and splicing elements of ordinary maps in any form to form new maps, and can synthesize information such as images, sounds, and texts to achieve various display effects. [0003] The query of public transportation information is an important application branch of electronic map. At present, many electronic map products provide...

Problems solved by technology

[0005] Due to the randomness of the manual entry method, there may be entry errors. In order to avoid errors, it is necessary to check the manually entered data. The current verification method is to manually check the data collected by the equipment and the manually entered data. For comparison, it not only consumes a lot of labor costs, but also the verification efficiency is low
