Illustrate, for the distance of terminal by light signal strength measuring terminals relative target object.Under normal circumstances, the intensity of reflected light becomes inverse correlation with the distance of terminal relative target object.But when the absorptivity of target object to light is larger, when the distance of terminal relative target object is less than certain distance, the intensity of reflected light becomes positive correlation with the distance of terminal relative target object, when the distance of terminal relative target object is greater than certain distance, the intensity of reflected light just becomes inverse correlation with the distance of terminal relative target object, and the relation of the intensity of reflected light and the distance of terminal relative target object can be as shown in Figure 2.Wherein, this light can be infrared light.Can find from the relation of the distance of the intensity of the reflected light shown in Fig. 2 and terminal relative target object, the intensity of a reflected light may corresponding two distance values, thus cannot by the distance of the intensity determination terminal relative target object of a reflected light.Therefore, the intensity of at least two reflected light can be obtained.
S102, obtain the exercise data of terminal by attitude sensor.
In the present embodiment, attitude sensor can be acceleration transducer, also can acceleration transducer and gyroscope etc. can the sensor of measuring terminals move distance, the present embodiment is not construed as limiting.
S103, the variable quantity utilizing this signal intensity and this exercise data, determine the current operation mode of range sensor.
In the present embodiment, the intensity of the reflected light according to Fig. 2 and the relation of terminal relative target object, when the distance of terminal relative target object is less than distance T2, the intensity of reflected light becomes positive correlation with the distance of terminal relative target object, therefore, when can think that the distance of terminal relative target object is less than T2, range sensor is in a mode of operation; When the distance of terminal relative target object is greater than distance T1, the intensity of reflected light becomes inverse correlation with the distance of terminal relative target object, and therefore, when can think that the distance of terminal relative target object is greater than T1, range sensor is in another mode of operation.As shown in the figure, range sensor in each pattern, the distance of the intensity of an a reflected light only corresponding terminal relative target object, therefore, first can determine the operational module of range sensor, then the distance of intensity determination terminal relative target object according to reflected light.
