Fig. 3 is a schematic flow chart of a data processing method according to an embodiment of the present invention. The data processing method described in this embodiment includes:
301. and the data acquisition equipment sends the motion data of the target object to the server.
Accordingly, the server receives the motion data.
The motion data may include angular velocity data, and time data, among others.
Specifically, the data acquisition device acquires motion data of the target object according to a certain sampling frequency, and can transmit the acquired motion data to the server according to a certain time interval.
In some possible embodiments, to avoid over-stressing the server by sending data to the server frequently, an appropriate time interval may be matched according to the performance of the server.
302. And the server acquires motion trail information according to the motion data.
Specifically, the server may determine the movement direction of the target object according to the angular velocity data, determine a position point (marked as a feature point) where the movement direction changes in the movement track of the target object according to the movement direction, and determine the movement path length of the target object in a time period corresponding to the time data according to the velocity data and the time data, so as to use the movement direction, the movement path length, and the feature point as the movement track information of the target object.
In some possible embodiments, the specific way for the server to determine the moving direction of the target object according to the angular velocity data may be:
The angular velocity data of the three-axis gyroscope is obtained by the inertial sensing module, and the server records the angular velocity data as: gx,gy,gz. Wherein, gx,gy,gzIn particular, it may be an average value over the above time intervals. Then:
wherein
Is the rotation angular velocity of the moving carrier coordinate system N relative to the standard reference coordinate system T.
The server constructs a differential expression of the quaternion:
the expanded expression is as follows:
wherein, P0,P1,P2,P3Four elements of a quaternion q.
The server calculates the solution of the quaternion q differential equation by using a first-order Runge-Kutta method:
Simultaneously:
the server solves an attitude matrix, namely a coordinate transformation matrix from a moving carrier coordinate system N to a standard reference coordinate system T by using the solution of quaternion:
since the quaternion q of the rigid rotation is a normalized quaternion, the above equation can be converted to:
note the book
Because the rectangular coordinate system is always kept in the coordinate system conversion process, the rectangular coordinate system is adopted
Is an orthogonal matrix, so:
the movement direction angle Ψ is:
The movement direction angle Ψ refers to the degree to which the current movement direction changes relative to the previous movement direction, and the larger the movement direction angle Ψ, the farther the deviation from the previous movement direction.
In some possible embodiments, if the movement direction angle Ψ is within a small range of values (e.g., 0 ° to 10 °), the server may consider the movement direction to be unchanged; if the movement direction angle Ψ reaches a certain angle threshold (e.g., 40 °), the server may consider that there is a possibility of a change in the movement direction.
To prevent false determination, the server may determine that the movement direction is changed when the Ψ value continuously reaches the threshold value for a period of time (e.g., 10 seconds).
The specific manner of determining the feature points by the server according to the motion direction may be: and determining corresponding position points when the motion direction in the motion trail changes as the characteristic points.
In some possible embodiments, the specific way for the server to determine the movement path length of the target object in the time period corresponding to the time data according to the speed data and the time data may be: the speed detection module and the time metering module respectively obtain real-time data of the movement speed and the time, and the server respectively records as: v, t. Let t be the corresponding time when the direction of motion changes1The moment when the direction of movement changes again is t2And calculating the average speed of the speed sampling points:
then from t1To t2The length of the motion path of the target object in the corresponding time period is as follows:
it should be noted that the above specific embodiments of determining the movement direction, the movement path length, and the feature point according to the movement data are only examples, and include, but not limited to, the above embodiments.
303. And the server generates a motion trail drawing instruction according to the motion trail information under the condition that the motion trail of the target object is lost.
304. And the server sends the motion trail drawing instruction to the client.
Correspondingly, the client receives the motion trail drawing instruction.
Specifically, the server may send the motion trail information to the client in the form of a motion trail drawing instruction. The server can acquire map application data of the client before sending a motion trail drawing instruction to the client, judges whether the map application interface of the client has the condition of motion trail deletion of the target object or not according to the map application data, and if the map application interface of the client has the motion trail deletion, the server needs to send the motion trail drawing instruction to the client to indicate the client to complement the part of the motion trail which is deleted on the map application interface; if the motion trail is not missing, the motion trail displayed on the map application interface is complete, and a motion trail drawing instruction can not be sent to the client.
In some feasible embodiments, the determination of whether the movement track of the target object is missing may also be performed by the client, that is, the client may obtain the map application data, determine whether the movement track of the target object on the map application interface is missing according to the map application data, and send a notification message to the server if the movement track of the target object is missing. And after the server acquires the motion trail information according to the motion data, if the notification message is received, determining that the motion trail of the target object is missing, generating a motion trail drawing instruction according to the motion trail information, and sending the motion trail drawing instruction to the client.
In some feasible embodiments, the server may also obtain map application data of the client before obtaining the motion trajectory information according to the motion data, and determine whether a situation of motion trajectory loss exists on a map application interface of the client according to the map application data, and if the motion trajectory loss exists, the server needs to obtain the motion trajectory information according to the received motion data; if the motion trail is not missing, the motion trail displayed on the map application interface is complete, and the received motion data can not be processed to obtain the motion trail information, so that the data operation pressure of the server can be reduced.
305. And the client outputs a map application interface, draws an instruction according to the motion trail and draws the missing part of the motion trail of the target object on the map application interface according to the motion trail information.
Specifically, the client may obtain current map application data, determine a missing position of the movement track of the target object according to the map application data, draw the missing part of the movement track on the map application interface according to the movement direction, the movement path length, and the missing position, and mark a feature point in the missing part of the movement track of the target object.
For example, as shown in fig. 4, if the client determines that the missing position of the motion trajectory is a path from the point a to the point C according to the map application data, the client may extend the corresponding motion path length 1 from the point a to the corresponding motion direction 1 to obtain the point B, and then extend the corresponding motion path length 2 from the point B to the corresponding motion direction 2 to obtain the point C.
In some possible embodiments, since the motion direction at the B point changes, that is, the B point is a feature point, the client may perform special marking on the B point, for example, adjust the color of the B point to be red different from the non-feature point, or add a blinking effect at the B point, or the like.
In some possible embodiments, the server may further directly instruct, in the motion trajectory drawing instruction, the client how to draw the motion trajectory, specifically including: the server may obtain current map application data of the client, determine a motion trajectory drawing rule according to the motion trajectory information and the map application data, where the motion trajectory drawing rule may include, for example, a motion direction corresponding to each motion path length and how the motion path lengths are spliced (including a splicing order, etc.), and generate a motion trajectory drawing instruction according to the map application data, the motion trajectory information, and the motion trajectory drawing rule.
In some possible embodiments, if the motion trail drawing instruction includes a motion trail drawing rule, the client may draw a missing part of the motion trail of the target object on the map application interface and mark a feature point in the missing part directly according to the motion direction, the motion path length and the motion trail drawing rule.
In some feasible embodiments, the server may also generate a motion trail drawing instruction directly according to the motion trail information without considering whether the motion trail of the target object is missing, and send the motion trail drawing instruction to the client, after the client receives the motion trail drawing instruction, before the motion trail of the target object is drawn on the map application interface, the client may judge whether the motion trail is missing on the map application interface according to the map application data of the client, and if the motion trail is missing, the missing part of the motion trail of the target object is drawn on the map application interface, so that the missing part in the motion trail is completed, and the situation that the same motion trail is repeatedly drawn when the motion trail is missing is avoided.
In the embodiment of the invention, the server acquires the motion trail information of the target object according to the motion data acquired by the data acquisition equipment, and sends a motion trail drawing instruction to the client according to the motion trail information under the condition that the motion trail of the target object is missing, the client draws the instruction according to the motion trail and draws the missing part of the motion trail of the target object on the map application interface by combining the motion trail information, so that the missing part can be supplemented when the motion trail is missing on the map application interface of the client, and the motion trail of the target object can be accurately and completely displayed.
