Intelligent-terminal-based indoor and outdoor environment detection method integrating various technologies

Abstract

The invention discloses an intelligent-terminal-based indoor and outdoor environment detection method integrating various technologies. The intelligent-terminal-based indoor and outdoor environment detection method adopts sensors of intelligent equipment for performing indoor and outdoor environment identification, and adopts three sub-detectors, wherein an optical detector utilizes an optical sensor to obtain light intensity of ambient environment, a distance sensor and time information cooperate for detection, a magnetic field detection makes judgment on the basis of magnetic field intensity, and a base station cellular detector makes judgment on the basis of cellular signal changes. The indoor and outdoor environment detection method designs adaptability threshold values of indoor and outdoor detection in the three manners according to specific environments, speculates the indoor and outdoor confidence degrees in various manners, designs the weight of adaptability, and obtains indoor and outdoor judgment results, so as to select different positioning mechanisms accordingly. The indoor and outdoor environment detection method does not need to spend a large amount of cost for additionally arranging a peripheral identification module on the equipment, and the joint detection method integrating various technologies disclosed by the invention has higher accuracy rate when compared with a detection method relying on a sub-detector independently.

Description

technical field [0001] The invention belongs to the technical field of environment identification and positioning, and relates to an indoor and outdoor environment detection method based on the fusion of multiple technologies of an intelligent terminal. Background technique [0002] For different environments, especially the distinction between indoor and outdoor, the adopted positioning schemes are very different. Following the principle of adapting to the specific environment, and then adopting corresponding positioning methods, can also achieve the purpose of significantly saving energy, so indoor and outdoor identification is of great help to energy-saving positioning. Moreover, indoor and outdoor environment detection can also provide guidance for services that depend on the scene environment, such as scene activity perception and image recognition. [0003] At present, the common methods for distinguishing indoors and outdoors have corresponding advantages and disadva...
