Description
Technical Field
The invention relates to a walking track recording system and a method thereof, in particular to a moving track recording system and a method thereof based on an intelligent terminal.
Background
In the prior art, when positioning a walking track of a user, modes of GPS positioning, base station WiFi positioning, and mixed positioning of the two are generally adopted. Specifically, the current specific geographical position information and the historical specific geographical position information of the target are obtained through network signals, and the moving track of the target is recorded by combining a map of a related area. If the specific position of the history of the user is Hangzhou and the specific position of the current history is Shanghai, the specific position is matched with a map of the area of Hangzhou Shanghai for use, and therefore the movement locus of the target is drawn. The method is more suitable for positioning and moving track recording in a larger range.
Specifically, for example, a wireless positioning method based on observer moving track signal scene analysis is disclosed in the chinese patent with the application number of 201210020550.0 and the invention name of "wireless positioning method based on observer moving track signal scene analysis", and includes the following steps: 1) providing an observer with a GPS (global positioning system), an electronic map and a detector capable of distinguishing target signal energy and direction, enabling the observer to surround the target for a circle, and recording the position of the observer, the target signal energy and the direction in the moving process; 2) performing peak-valley analysis on the recorded energy extreme values of the observation points, finding one or more peak points of the energy extreme values in the movement process of an observer, and taking the point with the maximum signal energy as a peak candidate point; taking a point which has the maximum value after the point with the maximum energy and undergoes jumping energy valley as a second peak candidate point, and repeating the steps until all energy extreme points in one circle around the track are found as other peak candidate points; 3) comprehensively evaluating the peak candidate points to obtain possible positions of the target, and marking the possible positions on an electronic map as follows: A. aiming at the condition that only one energy peak is available, making an extension line towards the direction of an energy extreme value on a peak candidate point, then optionally making extension lines towards the direction of the energy extreme value on a plurality of observation points far away from the peak candidate point until the observation points are intersected with the extension lines of the peak candidate point, and taking the point formed by intersection as the position of a target object; B. for the condition of a plurality of energy peaks, if the direction of the energy extreme value of the peak candidate point deviates from the direction of the moving track, the direction of a large object around the peak candidate point is required to be utilized to carry out reflection model correction on the deviating direction; and taking a point or an area formed by the intersection of the energy extreme value directions of the peak candidate points or the extension lines of the corrected directions as the position of the target object.
However, the above method has a high requirement for the external environment, and in some specific cases, such as in a valley, an underground parking lot, and a subway, the method cannot be connected to a network signal, such as a GPS satellite signal, a mobile network signal, and no WiFi signal, and cannot achieve target positioning, and thus cannot record a target walking track.
In addition, in the prior art, when a target is positioned, only the linear displacement and the planar displacement of the object can be determined, namely, the two-dimensional positioning is realized. For some complex track changes, such as wells, swimming and the like, three-dimensional positioning of a target cannot be realized, and certain limitations exist.
With the continuous development of science and technology, the application of the intelligent terminal is more and more extensive, and the function is more powerful, so that the record of the movement track realized by applying the intelligent terminal in the future becomes an advanced and convenient mode.

Referring to fig. 1, the intelligent terminal-based walking track recording system of the present invention includes an intelligent terminal 1, a direction sensing module 2, a step counting module 3, and an air pressure module 4. The intelligent terminal 1 comprises a processing module. The direction sensing module 2, the step counting module 3 and the air pressure module 4 are all arranged on the intelligent terminal 1 and are in communication connection with the processing module.
The direction sensing module 2 is used for acquiring an angle change value of the target in the horizontal direction. The direction sensing module 2 can sense an angle change value of the target compared with a reference direction according to the setting. Such as the angle change value compared to the true south and north directions. Preferably, the direction sensing module employs a direction sensing sensor.
The step counting module 3 is used for acquiring a distance value of the movement of the target. Specifically, the step counting module 3 calculates the moving distance of the target by sensing the number of steps taken by the target and combining the step distance set by the user. Preferably, the step-counting module adopts a pedometer.
The air pressure module 4 is used for acquiring a height change value of the target in the vertical direction. Specifically, the air pressure module 4 obtains a height change value of the target in the vertical direction by sensing an air pressure change at a relative height of the target and converting the air pressure change into an external vertical height change. Preferably, the air pressure module adopts a barometer.
The processing module is used for calculating the moving track of the target according to the data acquired by the direction sensing module, the step counting module and the air pressure module.
Preferably, the processing module displays the movement trajectory of the object on a map. The map is a map carried by the intelligent terminal or downloaded by the intelligent terminal.
Referring to fig. 2, the method for the processing module to calculate the movement track of the target is as follows:
setting O as the position of the target when the target is recorded last time, A as the current position of the target, B as the projection of the current position of the target in the y-axis direction, C as the projection of the current position of the target in the z-axis direction, E as the projection of the current position of the target on the horizontal plane, OA as the distance value of the target movement acquired by the step counting module, and OC as the height change value of the target in the vertical direction acquired by the air pressure module; the angle BOE is an included angle of the current position relative to the positive north, namely an angle change value of the target in the horizontal direction acquired by the direction sensing module. Namely, the values of OA, OC and & lt BOE can be respectively obtained by the step counting module, the air pressure module and the direction sensing module.
As can be seen from the above, the present invention,
setting the coordinate value of point A relative to point O as (x, y, z), then
And x is OE sin BOE, namely the variation of the point A relative to the point O on the x axis.
y ═ OE ═ cos ═ BOE, i.e., the amount of change in the y axis at point a relative to point O.
And z is OC, namely the variation of the point A relative to the point O on the z axis.
Therefore, the coordinate change amount of the point a with respect to the point O is easily calculated by a known condition. Every time the target moves forward, the coordinate point of the current position relative to the previous step can be calculated. And connecting all coordinate points to form a three-dimensional moving track graph of the target.
Preferably, the intelligent terminal further comprises an information entry module. The information entry module is used for entering the mark information at a specific position. Wherein the specific location may be an intersection, a downhill slope, etc. Specifically, in the intelligent terminal, the information entry module may adopt an existing camera module, recording module and/or memo module on the intelligent terminal. The marking information can be entered by means of a photograph, voice and/or text.
When the information recording module is used for recording the mark information, the processing module adds the mark information to the corresponding position on the moving track of the target.
When the user returns on the original way, the direction sensing module, the step counting module and the air pressure module still continuously acquire data, and the calculation is continuously carried out through the processing module. When the fact that the user arrives at the specific position is detected, the intelligent terminal displays/plays the stored marking information to the user, and clear prompt is given to the user. And when the return route selected by the user does not accord with the previously marked route, the intelligent terminal gives out a voice warning. If the user selects a return route different from the previous route, the processing module continues to calculate the movement track of the user from the bifurcation point, and calculates and reminds the user of the distance between the user and the bifurcation point so as to return to the point for reference and use if necessary.
For example, when the user is at an intersection, the user subjectively turns on the camera module to acquire a picture of the intersection. The processing module processes the photo, sequentially marks the branches on the photo (for example, objects with signs at each branch can be selected and numbered, such as trees, stones and the like), and stores the selected relevant information of the branches through marking information such as voice and/or characters. When the user returns, the selected branch route can be more intuitively viewed by means of the labeled information such as a photograph, voice, and/or text.
Specifically, if an intersection is encountered at a point O, key markers of the intersection are sequentially marked as 1, 2, 3 and a on the picture, wherein the number 3 is an entrance when the user reaches the point O, the point a is an exit when the user reaches the point O, the processing module integrates the actual motion track with the picture, and the route selected at the point O is marked as a special color in the actual picture. When the user returns to the point O, the photograph of the actual mark and the moving trajectory are simultaneously displayed on the intersection, so that the user can easily find the route selected at the time of arrival. And if the selected route is different from the route marked before when the user returns, calculating and recording the track of the user from the bifurcation point again, and reminding the user of the distance from the bifurcation point at any time so as to return to use if necessary.
