And used time in the fixed time period；
This step calls the rear camera of the mobile phone to obtain level of the mobile phone within the set time in real time
Moving distance and time used within the set time, while obtaining in the start time and terminal of the set time
When quarter, the horizontal distance between the mobile phone and the potential risk object, such as when the set time is 2min,
Get the mobile phone in 2min described in move horizontally distance be 20m, and the start time of 2min it is described it is horizontal away from
It is 70m in the horizontal distance of the end of time of 2min from for 100m.
S202, distance and the time calculating mobile phone travelling speed are moved horizontally according to；
In this step according to get it is described move horizontally distance and the time calculates the mobile phone travelling speed, than
As the time be 2min, in 2min described in move horizontally distance be 20m, then can be calculated the mobile phone travelling speed is
10m/min。
S203, the mobile phone described in the start time and end of time of the fixed time period and the potential risk object are obtained
The horizontal distance between body, according to the horizontal distance, it is described move horizontally distance and the time calculate it is described potential
The movement speed of risk object；
According to the horizontal distance, the water of the set time start time of acquisition and end of time in this step
Flat moving distance and the time calculate the movement speed of the potential risk object, for example the time is 2min, in 2min
The horizontal distance of start time be 100m, be 70m in the horizontal distance of the end of time of 2min, the institute in 2min
Stating and moving horizontally distance is 20m, then the distance that moves horizontally that the potential risk object in 2min can be obtained is 10m, is calculated
The movement speed that the potential risk object can be obtained is 5m/min.
By the calculating of the movement speed to the mobile phone travelling speed and the potential risk object in the present embodiment, it is
Subsequent judgement direction of advance provides foundation with the presence or absence of risk.
In one embodiment, described that distance and the mobile speed of the time calculating mobile phone are moved horizontally according to

Dynamic speed, such as the time are 2min, in 2min described in move horizontally distance be 20m, substituting into formula can be calculated
The mobile phone travelling speed is 10m/min.
The present embodiment is by the calculating to the mobile phone travelling speed, to whether there is risk on line direction before subsequent judgement
Provide judgement basis.
In one embodiment, acquisition mobile phone described in the start time and end of time of the fixed time period with
The horizontal distance between the potential risk object, according to the horizontal distance, it is described move horizontally distance and it is described when
Between calculate the movement speed of the potential risk object, comprising:
Distance, the calculated result of the horizontal distance and the time are moved horizontally according to described, is calculated described potential
The movement speed of risk object, shown in calculation formula such as formula (3),
In formula (3),
vwIndicate the movement speed of potential risk object w,
The horizontal distance of w between the mobile phone r and potential risk object of the start time of l expression time period t,
ltIndicate the horizontal distance between the mobile phone r and potential risk object w of the end of time of time period t,
lrIndicate that time period t mobile phone r's moves horizontally distance；
The horizontal distance that will acquire in this step, it is described move horizontally distance, the time substitutes into formula and falls into a trap
Calculation obtains the movement speed of the potential risk object, for example the time is 2min, in the water of the start time of 2min
Flat distance is 100m, is 70m in the horizontal distance of the end of time of 2min, and described in 2min moves horizontally distance and be
20m, substituting into and can be calculated the movement speed of the potential risk object in formula is 5m/min.
By the calculating of the movement speed to the potential risk object in the present embodiment, on line direction before subsequent judgement
Judgement basis is provided with the presence or absence of risk.
