Problems solved by technology

[0004] However, the cost of comprehensive inspection is too high. The largest expenditure in the map production process is the part of field collection. Comprehensive inspection means "secondary collection", doubling the production cost, and comprehensive inspection is not efficient. It may be able to keep up with the speed of updating the version of the navigation electronic map product
Due to the gradual increase in the publication frequency of navigation electronic map products, the comprehensive inspection cannot keep up with the publication frequency of navigation electronic map products, resulting in the loss of timeliness in the quality inspection results of the comprehensive inspection

Abstract

The invention provides a method and device for randomly detecting and evaluating navigation electronic map quality, which belong to the technical field of navigation. The method comprises the steps of randomly selecting navigation electronic map information of an area to be detected from a navigation electronic map; obtaining field data of the area to be detected; comparing the selected navigation electronic map information of the area to be detected with the obtained filed data of the area to be detected so as to obtain comparing results; counting the comparing results and calculating an average correct rate of the comparing results according to the count comparing results; and obtaining an integral quality distribution level of the navigation electronic map product through calculating a detecting and evaluating result of a sample area. Therefore, quality detecting efficiency of the navigation electronic map product is effectively increased and the timeliness of the detecting result is assured.

Description

technical field [0001] The invention belongs to the technical field of navigation, in particular to a random detection and evaluation method and device for the quality of a navigation electronic map. Background technique [0002] The core value of navigation electronic map lies in quality. With the continuous improvement of production technology, the version update speed of navigation electronic map products is increasing, and the existing inspection methods are not suitable for the current situation. A set of corresponding methods is needed to quickly understand the quality status of navigation electronic map products. [0003] At present, the way to grasp the quality level of navigation electronic maps is: the combination of comprehensive inspection and manual designated area detection, and the method of comparing data with the scene. Comprehensive inspection is to reconfirm all navigation electronic map information, that is, to compare all roads and points of interest wi...
