Can be associated with the classification of the dangerous material belonging to target object, think that this belongs to when above-mentioned area is greater than preset area threshold
Danger brought by the target object of dangerous goods is larger, and the degree of threat may be brought to rise to user, can be based on above-mentioned
Target object and above-mentioned area export reminder message, so that user can not only know dangerous article around itself, but also
The size that can know that the dangerous goods, allows user to be taken precautions against.
Therefore by the embodiment of the present application, the external world is first judged using the wireless transmission and receive capabilities of mobile terminal
In whether there is predefined type target object, whether the target object is then judged by the image information of the target object again
Belong to dangerous goods, is realized with this and quickly detect user's dangerous goods that may be present at one's side in a short time, so that user exists
In the case where indulging in mobile terminal without paying close attention to external environment, the danger in external environment can be identified in time
Product help user to recognize the danger that may be present of current environment institute, improve the safety of user to a certain extent.To also simultaneously
Reminder message is exported in dangerous article, so that user is more deep to the understanding of above-mentioned dangerous goods.
Optionally, on the basis of above-described embodiment one and embodiment two, above-mentioned steps 102 and step 202 are specifically included:
C1, the frequency of above-mentioned reflection signal is detected whether in preset frequency separation, wherein above-mentioned preset frequency zones
Between it is associated with above-mentioned predefined type；
If the frequency of C2, above-mentioned reflection signal is in preset frequency separation, it is determined that reflect the object of above-mentioned wireless signal
There are the target objects of predefined type in body.
In the embodiment of the present application, since the affiliated type of object in external environment is very more, and different types of object
The reflected reflection signal of institute is also that the parameter of diversified namely each reflection signal is not identical, thus, it can basis
The frequency for reflecting signal determines the target object that whether there is predefined type in the object for reflecting above-mentioned wireless signal.Can by pair
Above-mentioned reflection signal is analyzed, and is detected and be whether there is the reflection signal for falling into preset frequency separation in above-mentioned reflection signal,
If there is the reflection signal for falling into preset frequency separation in above-mentioned reflection signal, the above-mentioned wireless signal of reflection can be determined
There are the target objects of predefined type in object, are realized with this and quickly determine whether there is target object by reflecting signal.
Optionally, on the basis of above-described embodiment one and embodiment two, above-mentioned steps 103 and step 203 are specifically included:
D1, preset frequency separation is set by the frequency reception signal section of above-mentioned mobile terminal, wherein above-mentioned default
