Step number, calculates average step length.It should be noted that the data of collection are preferably selected on direct route.
In the above method one and method four, especially method three and method four can use two step calculating methods, to improve
Accuracy.Specifically：
First, a discreet value is obtained；
Then, in navigation procedure, by user according to real-time monitored, navigation results are made with feedback, according to feedback adjustment
The discreet value of step-length.
In certain embodiments, the indoor two-way air navigation aid is applicable to multiple different users.Specifically, use
The above method is obtained after step-length, while storing the step value obtained, stores the corresponding user of the step value；Can exist simultaneously
Step-length corresponding with oneself may be selected in a plurality of user profile, different users.
In step 340, the position of user is obtained and records in real time, and form movement locus in navigation procedure.Remember herein
Movement locus is recorded, is still recorded in the way of step number+direction of walking.
In some cases, movement locus is overlapped with navigation way；In some cases, the two is to partially overlap
, for example：When being navigated by navigation way in market, the shop strolled near lower navigation way may be on the way gone to temporarily.
Therefore, while retaining and showing navigation way and movement locus, on the one hand, be easy to user by contrasting navigation way and motion rail
Mark, more easily reaches default destination；On the other hand, it is easy to subsequent user by actual movement locus reverse navigation.
In step 340, the reverse navigation request of user is such as got, then according to movement locus reverse navigation, reverse navigation
Represented with walking step number and direction.When user under some particular cases, it is necessary to during backtracking, then can be according to movement locus
Carry out reverse navigation.
The opportunity of direction navigation can be user after navigation purpose is reached；Or any position in navigation procedure.
The indoor two-way air navigation aid that the application is provided, concrete application scene citing：
User A needs to go to buy shoes from family to certain market B；
A first passes through conventional airmanship (at least suitable for outdoor navigation), navigates to market market B entrance；
The position of entrance is obtained, A direction is obtained using compass；
A input navigation requests (A have input " shoes store "), five shoes store in market are determined according to navigation requests, and A is screened
Therein three are used as final destination；
According to final destination, it is determined that navigation way；GPS location is now just eliminated the reliance on, next coordinates pedometer,
And based on user's Stature estimation step-length, displacement is obtained with step-length × step number, compass confirms moving direction, air pressure sensing
Device and three-axis gyroscope estimation stair activity floor switching, so far build the three dimensions in building, can be as accurate as deploying to ensure effective monitoring and control of illegal activities
User current location processed；Mainly based on two-dimensional coordinate plane, during height change, the two dimensional topology figure of switching correspondence floor.Can
The prompting how much walked is walked to certain direction to provide user, indoor navigation is realized；
When user is being strolled to the 3rd shoes store, discovery lost key, or need first hand shoes store to replace shoes；
Need to return along road, then start reverse navigation function by secondary or physical bond or other modes；Carry out reverse navigation；
