The steps shown. It should be noted that although the above-mentioned electronic device 90 is taken as an example to describe the path information processing method disclosed in the present invention, the path information processing method of the present invention is not limited to the above-described electronic device 90.

First, step S401 is performed: providing an input interface displayed on the screen of the electronic device.

In the embodiment of the present invention, when the user wants to record the path that he is about to walk under a certain situation, the user can click on the screen 91 to represent the pattern of the path information processing system 1 of the present invention. (not shown) to start the path information processing system 1. For example, as shown in FIG. 5, when the user drives to the department store to eat, after the car is parked to the underground second floor parking lot, if it is worried that the returning car can not find the parking space of the parking lot smoothly, , the path information processing system 1 can be started.

As shown in FIG. 2 and FIG. 3, after the path information processing system 1 is activated, the interface providing module 10 first displays an input interface UI on the screen 20 for the user to input through the input interface UI. The starting point data and the ending point data of the path.

Step S402 is executed: receiving an information collection instruction.

In the embodiment of the present invention, after inputting the start point data and the end point data, the user can input an information collection instruction by clicking the confirmation button B displayed on the input interface UI. The input information collection instruction will be received by the instruction receiving module 20. It should be noted that, in other embodiments, the path information processing method of the present invention is not necessary to perform step S401, that is, it is not necessary to first require the user to input the starting point data and the ending point data (may also be completed). After the path is recorded, the information collection instruction can provide input through other means, for example, setting a physical button on the electronic device 90 for the user to press and input, or displaying other interfaces on the screen 20 for the user to operate. Input. In addition, even if the input interface UI is provided for the user to input the start point data and the end point data, the information collection command can be input through other interface operations, in other words, the input of the start point data and the end point data does not need to pass through the same interface.

Step 403 is executed: receiving displacement state information of the electronic device sensed by the motion sensing system, and detecting geomagnetic information during the change of the position of the obtained electronic device by the geomagnetic sensor.

After the path information processing system 1 receives the information collection command, the motion sensing system 92 transmits the displacement state information of the sensed electronic device 90 to the path information processing system 1 once the user of the handheld electronic device 90 starts moving. And received by the information collection module 30. At the same time, the geomagnetic sensor 93 also transmits the geomagnetic information during the change of the position of the obtained electronic device 90 to the path information processing system 1 and is received by the information collecting module 30. For example, when the user of the handheld electronic device 90 moves from the position where the parking space is located to the position where the elevator on the same floor is located, if the walking path is as shown in FIG. 6, the motion sensing system 92 first feels The displacement state information of the electronic device 90 moving a few meters (for example, 20 meters) is moved southward, and the geomagnetic sensor 93 detects the geomagnetic information during the change of the position of the electronic device 90. The obtained displacement state information and geomagnetic information are transmitted to the route information processing system 1 and received by the information collection module 30.

When the user turns and travels a few meters, the motion sensing system 92 senses the displacement state information of the electronic device 90 that is turned southward toward the east and displaced by several meters. The geomagnetic sensor 93 will detect The geomagnetic information during the change of the position of the electronic device 90 is obtained. Similarly, after the displacement status information and the geomagnetic information are acquired, they are transmitted to the path information processing system 1 and received by the information collection module 30.

Similarly, after the electronic device 90 shifts and moves the distance and other displacement state information (for example, as shown in FIG. 6 , the electronic device 90 is then turned from the east to the north for a few meters, and then turned to the north for a few meters) Both of them are sensed by the motion sensing system 92, and the geomagnetic information of the electronic device 90 during each position change is also detected by the geomagnetic sensor 93, and both are transmitted to the path information after being acquired. The system 1 is processed and received by the information collection module 30.

Step 404 is performed: calculating path information of the displacement of the electronic device according to the displacement state information and the geomagnetic information.

After receiving the displacement state information and the geomagnetic information, the path information processing system 1 calculates the path data of the displacement of the electronic device 90 according to the received displacement state information and the geomagnetic information. For example, taking the above example as an example, when the obtained displacement state information is southward (the mobile orientation is provided by the electronic compass 921), the movement speed is 15 km (provided by the acceleration sensor 923) for 10 seconds, and the calculation is performed at this time. The module 40 can calculate the path data of the displacement of the electronic device 90 based on the information, and can further synchronously draw a road map of the displacement of the electronic device 90. Since the information obtained by the sensing elements such as the electronic compass 921, the gyroscope 922, the acceleration sensor 923, etc., to determine the displacement state and route of the electronic device 90 is a well-known technique, it is well known to those of ordinary skill in the art. The details of the principles are disclosed in many patents and published technical documents, so no further details are provided herein.

In addition, each time the path information processing system 1 obtains the displacement state information, while calculating the path data of the electronic device 90 displacement, the further calculation module 40 determines whether the position of the electronic device 90 is high or not based on the displacement state information. The level changes. When it is determined that the position of the electronic device 90 changes in height, but there is no horizontal change, the computing module 40 determines that the electronic device 90 is located at an elevator. The result of this judgment will be drawn at the corresponding position of the above road map, that is, the corresponding position on the road map will indicate the location of the elevator.

Further, after the calculation module 40 determines that the position of the electronic device 90 is located in the elevator, if it is determined that the position of the electronic device 90 changes horizontally according to the displacement state information obtained by the subsequent sensing, but the height is not changed, the calculation module 40 determines the electronic The location of the device 90 is located at the floor of the above-mentioned end point data, and it is determined that the position of the electronic device 90 before the level change occurs is the position of the elevator of the floor.

Step 405 is executed: recording the path data and the local magnetic information corresponding to the positions of the sampling points in the process of changing the position of the electronic device.

After the step S404 is completed, the recording module 50 stores the path data calculated by the calculation module 40 and the local magnetic information corresponding to the positions of the sampling points in the position change process of the electronic device 90 to the electronic device 90. In the memory (not shown). For example, when the user's handheld electronic device 90 walks from the elevator to the restaurant, in addition to the calculated path data being stored, the geomagnetic information of each point of the path through which the user walks is also subjected to the geomagnetic sensor. The sense 93 is acquired and transmitted to the route information processing system 1 and recorded by the recording module 50.

In the embodiment of the present invention, after the user arrives at the destination, the user can suspend or cancel the execution of the path information processing system 1 by operating the electronic device 90 to stop the path information from continuing to collect. It should be noted that, in the embodiment of the present invention, the recording operation of the path data and the geomagnetic information continuously continues with the displacement of the user, in other words, each time a new displacement state information and geomagnetic information is received, After calculating the path data according to the two, the recording module 50 temporarily stores the path data and the local magnetic information corresponding to the position of each point in the position change of the electronic device 90, and stops the path according to the above description by the user. After the collection of information, the path data that will be temporarily stored will be merged.

Finally, step 406 is performed: uploading path data, local magnetic information, starting point data, and end point data to a server system.

As shown in FIG. 1 and FIG. 2, when the information collection module 30 no longer receives the displacement information of the electronic device 90 as sensed by the motion sensing system 92, and the geomagnetic sensor 93 detects the position change process of the electronic device 90. In the geomagnetic information, the information uploading module 60 uploads the temporarily stored path data, the local magnetic information, and the starting point data and the ending data previously input by the user to the server system S for the server system. After obtaining a large amount of path data, geomagnetic information, starting point data and end point data, S may establish a map data according to each path data, geomagnetic information, starting point data and end point data. For example, in a building, multiple users upload different path data, geomagnetic information, starting point data and end point data according to the above methods. For example, user U1 uploads the path data from the 7th parking space to the 007 restaurant. User U2 uploaded the number from the No. 2 parking lot to the No. 017 counter. When the uploaded parking space data and the geomagnetic information are enough, the server system S can construct a plane map of the underground second floor parking lot accordingly. Similarly, after obtaining a plurality of end points (or starting points) located on the same floor but at different positions, the server system S can also construct a plane map of the floor. The creation of a flat map of each floor can be done in this way.

Finally, please refer to FIG. 1 , FIG. 2 and FIG. 8 together, wherein FIG. 8 is a flow chart of the second step of the path information processing method of the present invention.

When the user wants to return to the original starting position from the end position, for example, in the above example, when the user wants to return the parking space parked by the vehicle from the restaurant, the user can input an inquiry command to the path information processing system 1 by operating the electronic device 90. . At this time, the instruction receiving module 20 receives the query instruction (ie, performs step 801). After receiving the query command, the display control module 70 of the path information processing system 1 displays the path data previously calculated by the calculation module 40 on the screen 91 of the electronic device 90 according to the query command (ie, step 702 is performed). ) for users to view. As described above, since the calculation module 40 calculates the path data and draws the displacement road map of the electronic device 90, the path data displayed here may be, for example, as shown in FIG. 6 or FIG. 7. route map. When the road map is displayed on the screen 91, the user can follow the road map to return to the starting position.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. It should be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the invention is intended to be limited by the scope of the claims.
