Method and system for recognizing indoor and outdoor scenes

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.
