Embodiment Construction

[0084] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0085] figure 1 A simple and effective method for recognizing indoor and outdoor scenes with low power consumption according to an embodiment of the present invention is given. The method utilizes data collected by one or more sensors in the mobile terminal to identify indoor and outdoor scenes. Generally, existing mobile terminals have wireless communication functions and various sensors, such as light sensors, proximity sensors, acceleration sensors, gyroscopes, magnetic sensors, temperature sensors, air pressure sensors, sound sensors, GPS sensors, and the like. These sensors can c...

Abstract

The invention provides a method for recognizing indoor and outdoor scenes. The method comprises the following steps: collecting data which are related to the current state of a mobile terminal and the scene, in which the mobile terminal is, through one or more of an optical sensor, an acceleration sensor, a gyroscope, a magnetic sensor, an air pressure sensor, a temperature sensor and / or a global positioning system component of the mobile terminal; and judging whether the current scene, in which the mobile terminal is, is indoor or outdoor on the basis of the collected data. According to the method, data collection and analysis and indoor and outdoor scene reorganization are carried out by using the sensor of a mobile phone instead of any prior information; and the method can be used as lightweight service capable of running on the background of the mobile phone, and has the characteristics of high accuracy rate, short detection time delay, low energy consumption and wide universality.

Description

technical field [0001] The invention belongs to the technical field of wireless positioning and contextual intelligent perception, and in particular relates to a method for identifying indoor and outdoor scenes. Background technique [0002] Today's mobile terminals have become an important platform for environment perception and crowd communication. Effective indoor and outdoor scene recognition methods can provide the most useful environmental information for terminal applications, thus effectively improving the performance of mobile terminals. For example, in terms of location-based services, GPS can give relatively accurate inferences in outdoor environments, but performs poorly indoors due to the obstruction of satellite line-of-sight. In terms of mobile data services, indoors, mobile phones can scan more WiFi signals with stronger signal strength, while outdoors, the wireless connection effect is relatively poor. Therefore, if the indoor and outdoor scenes can be dete...
