Abstract

The invention relates to an extraction method and device based on a high-precision map data recommendation sample. The method comprises the following steps: obtaining a data source of a high-precisionmap; determining the number of recommended samples, sample data records and the number of elements according to inspection standards; collecting a coherence factor according to the data source; determining recommended samples meeting conditions according to the coherent factors and the elements; and randomly extracting the recommendation samples meeting the conditions. According to the method, the problem that manual selection of sampling data is tedious is solved, the sample selection time is saved, the extraction process of the high-precision map data recommendation samples is more scientific, and the sampling process reflects the overall situation more accurately due to more sample coverage.

Description

technical field [0001] The invention belongs to the field of high-precision electronic map production, and in particular relates to a method and device for extracting recommended samples based on high-precision map data. Background technique [0002] The element types and attribute types of high-precision maps are more abundant than traditional car navigation electronic maps, and there are also differences in service objects and usage scenarios. It is no longer possible to filter recommendation samples from a single information-assisted perspective. In the field of high-precision electronic map production, there is an urgent need for a sampling method that includes more accurate elements and attributes of traditional car navigation electronic maps as relevant factors to form data recommendation samples. Contents of the invention [0003] The present invention aims at the cumbersome manual selection of sampling data existing in the existing high-precision map data sample ex...
