Embodiment Construction

[0035] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0036] At present, the collection process of POI data is divided into field collection and in-house processing. Among them, in the field collection link, camera devices, panoramic cars, smart phones and other equipment are used to collect image data and coordinate data. After the data collection is completed, it enters the in-house processing link, where POI data is extracted and cleaned by in-house processing tools.

[0037] Since the field collection link and the in-house processing link are two separate links, the accurac...

Abstract

The invention provides a map interest point processing method and device, and the method comprises the steps: obtaining image data collected by a first user; preprocessing the image data to obtain a to-be-processed frame image from the image data; detecting whether each to-be-processed frame image contains an interest point or not; If the first frame of image contains the first interest point data, obtaining each effective interest point according to the collection position of the first frame of image; Verifying whether the first interest point is matched with any effective interest point or not; and if the first interest point is not matched with any effective interest point, determining that the collection position of the first frame image contains a to-be-updated interest point. According to the method, the processing efficiency can be improved, the acquisition period of the interest point data is shortened, and the acquisition cost is saved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for processing map interest points. Background technique [0002] With the continuous development of terminal technology and Internet technology, various application programs (Application, APP for short) have sprung up like mushrooms after rain. Users can install different types of APPs on terminal devices according to their own needs, such as map apps, social apps, payment apps, etc. The wide application of map apps makes users' lives more convenient. Among them, map data, that is, Point of Interest (POI for short) is the basis of the map, and users cannot travel without POI data with complete coverage and accurate coordinates. [0003] In the related art, the POI data in the map APP is collected and processed by a professional map manufacturer. [0004] However, this data collection method is not only costly, but also takes a long time f...
