Visual searching method applicable mobile terminal

Abstract

The invention provides a visual searching method applicable a mobile terminal. The method comprises the concrete processes including the steps that 1, the mobile terminal is utilized for collecting images to be identified of the current scene, and in addition, the gravity direction of the mobile terminal during the image collection and the GPS (global position system) information of the current scene are obtained; 2, the binary local feature vectors of the images to be identified are obtained; 3, the GPS information and the binary local feature vectors are packed into a descriptor file, and the descriptor file is sent out; 4, images corresponding to the GPS information with the shortest distance from the extracted GPS information are extracted from a sample image base, and are defined as inquiry images; 5, the images to be identified are subjected to one-to-one matching with the binary local feature vectors of the inquiry images, the inquiry images with the shortest distance from the images to be identified are found, in addition, corresponding information is transmitted to the mobile terminal, and the visual searching is realized. The method can provide a more convenient measure for users of the mobile terminal to obtain relevant information of the current scene.

Description

technical field [0001] The invention belongs to the technical field of mobile augmented reality, and in particular relates to a visual search method suitable for mobile terminals. Background technique [0002] The research goal of visual search is to use computers to replace humans to automatically process massive amounts of physical information, identify targets and objects in various patterns, partially replace human mental work, and expand the fields that human physiological organs are not capable of. Remote sensing image processing, medical image processing and augmented reality have a wide range of applications. [0003] At present, with the development of the Internet, human beings are stepping into an information society, and the Internet has become an important platform for human beings to publish, obtain and exchange information. The exponential growth of the amount of information on the Internet has made it an important issue for users to quickly and accurately fi...
