POI data acquisition system and method based on smart phone

Abstract

The invention discloses a POI data acquisition system and method based on a smart phone. The smart phone comprises a GPS positioning interface and a camera photo taking interface. The system comprises an application layer, a support platform, an interface layer and a management center, wherein the application layer calls a support platform to realize the relevant operation in a business function;the support platform realizes the general core function relating to bottom equipment in the business funciton; the interface layer integrates a GPRS communication interface, the GPS positioning interface and the camera photo taking interface and is realized by relevant Java interfaces; and the management center is in charge of distributing tasks to the smart phone and records and feeds back the result information of an acquisition task. The invention also provides a method based on the system. The invention has real-time task work order and step feedback, has the characteristics of wide platform support, visual and convenient use and multi-industry support and realizes the reliable acquisition of POI data.

Description

technical field [0001] The invention relates to the field of geographic information, in particular to a POI (Point of Interest, point of interest) collection system and collection method. Background technique [0002] With the development of location services and navigation applications, the ability to provide a large amount of accurate and effective POI data has become an important indicator for evaluating service levels. However, because POIs need to be collected on-site and require a lot of manpower and material resources, how to collect the most authentic, accurate, detailed and rich POI data has always been a difficult problem in the industry. [0003] At present, the common POI acquisition software system in China is mainly implemented by professional PDA (handheld computer) equipment under the WinCE system platform, and uses the GPS positioning function of the PDA to record the movement track of the acquisition personnel, and record a point when moving to a POI positi...

AI Technical Summary

Problems solved by technology

There are four main defects in this collection method: 1. The use of special software on special equipment can only be used by full-time personnel, which is not conducive to the use of part-time personnel and social promotion and application; 2. Most of them use offline systems, and there is no real-time connection with the server. Interaction, the real-time management of collection tasks is not high; 3. It is impossible to be sure that the point position recorded by GPS is indeed the real position of the POI, which depends on the professional quality of the collection personnel to ensure it; The corresponding relationship, artificial omissions and errors are difficult to detect
