detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In this embodiment, a motion track recording method is provided. FIG. 1 is a flowchart of a motion track recording method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

Step S102: Collect motion related data of a user holding the user equipment by using a sensor in the user equipment, where the motion related data at least includes: angular velocity and acceleration in a horizontal direction and a vertical direction;

Step S104, calculating a moving direction and a moving distance of the user according to at least the motion related data;

In step S106, the motion track of the user is recorded according to the moving direction and the moving distance.

Through the above steps, the motion-related data of the user holding the user equipment is collected by using the sensor of the user equipment, so that the motion direction and the motion distance of the user can be calculated according to the motion-related data, and the motion track of the user is recorded. In this way, on the one hand, it is no longer necessary to rely on external artificial signals (such as GPS signals, WIFI signals, etc.) to achieve user traffic. The recording of the trajectory, on the other hand, after the trajectory recording, the navigation can be performed within the range of the trajectory according to the recorded trajectory, instead of relying on the electronic map. It can be seen that the above solution solves at least the problem of relying on the electronic map for navigation, so that navigation can be realized without an electronic map.

Optionally, the sensor comprises at least: a sensor configured to collect angular velocity and acceleration in a horizontal direction and a vertical direction. For example, gyro sensors and gravity acceleration sensors (also known as gravity sensors). Moreover, in the embodiment of the present invention, the sensor is not limited to include other sensors.

For example, the sensors in the user equipment may also include geomagnetic sensors; the geomagnetic sensors utilize geomagnetism to achieve geographic direction determination. In this case, the acquired angular velocity and acceleration in the horizontal direction can be combined with the geographic direction of the geomagnetic sensor to convert the angular velocity and acceleration into the geographic direction.

For another example, the sensor in the user equipment may further include an air pressure sensor; the air pressure sensor uses the detection of the air pressure to determine the altitude. In this case, the motion related data may further include: altitude information. Through the air pressure sensor, the height change of the user's motion trajectory can be collected.

In addition, the sensors in the user equipment may further include: a temperature sensor, or even a body temperature sensor, a heart rate sensor, etc., which are set to detect the physiological condition of the user; some of the sensors may not help the navigation, but the motion trajectory may be adopted by these sensors. The user status or the user's environmental data is recorded.

In step S104, considering that the angular velocity and the acceleration collected by the sensor are generally instantaneous values, determining the motion distance of the user directly according to the angular velocity and the acceleration may generate a large error in a long time, and therefore, in the embodiment of the present invention, Combining the step information to correct the motion distance, for example, acquiring the step information of the user; determining the number of walking steps of the user according to the motion related data; calculating the moving direction of the user according to the motion related data, the step information, and the walking step number Movement distance. The step information of the user may be input by the user according to experience, or the user may input data related to the step information, such as height and weight information, thereby calculating the step information of the user; the number of steps of the user It can be obtained according to the pedometer principle of the related art, that is, counting the number of walking steps of the user by the gyro sensor and/or the gravity sensor.

Optionally, the motion track is composed of a plurality of recording points, wherein each of the plurality of recording points further includes information of at least one of: an altitude of the recorded point, a temperature of the recorded point, a time of the recorded point, Record user action information for the point. With this information, a broader application scenario can be achieved. For example, the user operation information is included in the record point information, and the user can take a photo at a certain point in time, or record a piece of text, and add the photo or text as user operation information to the record point information, so that When you include the motion track of the recorded point information to navigate or play back the motion track, you can view these photos or text again, which enhances the fun and enhances the user experience.

Alternatively, after the motion trajectory is recorded, the recorded motion trajectory may be utilized to provide navigation from the beginning of the motion trajectory to the end of the motion trajectory, or to provide navigation from the end of the motion trajectory to the beginning of the motion trajectory. For example, the user opens the trajectory digital map and uses the function of returning to the starting point. The mobile phone processor calculates the direction and distance that the user needs to travel according to the digital map of the user's motion trajectory acquired in the previous period, starting from the end point and combining the current trajectory of the end user. Finally, the user is prompted by voice and screen display, the direction of walking, and the approximate distance.

Wherein, the motion trajectory can be depicted on the electronic map, and in the absence of the electronic map, the motion trajectory itself can also serve as a navigation basis, and the user can initiate navigation at the beginning or end of the previous motion trajectory, thereby being able to navigate according to the original route or Navigate in the opposite direction of the original road. In addition, it is not excluded that the user starts to start navigation at a certain node position in the middle of the motion track. At this time, the user only needs to set the starting point of the navigation as the corresponding recording point position in the motion track. For example, in the motion track, the user takes a live photo at one of the recorded points; at this time, the user walks to the geographic location corresponding to the live photo, and after comparison, the user confirms the geographic location and records the live photo. The points are consistent. At this time, the user can click the record point if needed, and start navigation from the record point (where the end point of the navigation can be the start point, the end point, or another record point).

When the geomagnetic sensor is not provided, the detected direction of movement of the user equipment will only have opposite directions. For example, four directions may be indicated by “front”, “rear”, “left”, and “right”. For example, the direction of motion can be described by 20° to the left; thus, when recording the motion trajectory, the four directions of “front”, “rear”, “left”, and “right” can be used as a reference. recording. If the user wants to use the recorded motion trajectory for navigation, since there is no geographical direction indication in the recorded motion trajectory, the direction correction can be realized in various ways at this time. For example, when the user starts to record the starting point of the motion trajectory facing the north, he can first correct his or her face to the north and then open the navigation when navigating at the starting point, thus realizing the use of the relative direction of the navigation trajectory for the original path. In the same way, if the end point of the end of the recorded motion trajectory is facing north, the user can first correct his or her face to the south and then open the navigation when navigating at the end point, thus realizing the use of the opposite direction. The navigation track performs navigation for the original return. For another example, after the user turns on the navigation, the user can walk by a certain distance by using the memory. At this time, the sensor simultaneously detects the motion track of the user equipment, and then the user equipment compares and matches the newly detected motion track with the previous motion track, thereby realizing Correction of the direction of the user's walking route and the motion trajectory set to navigation; after the direction correction is implemented, the navigation of the original path re-entry or the navigation of the original return is performed according to the previously recorded motion trajectory.

Optionally, after the motion track of the user is recorded according to the motion direction and the motion distance, the track information may also be derived, wherein the track information includes a motion track. The exported track information may be stored on a non-volatile storage medium or shared with other user terminals of other users; other user terminals may play back, review motion tracks, or navigate according to motion trajectories.
