Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In order to solve the problems in the prior art, the inventor originally thinks that only one route track is displayed, namely all points can be directly plugged into a drawing library, the drawing library draws the route track and captures a track drawing point transformation event to achieve the operation of clearing the previous route track. However, such a solution has two problems: 1. some drawing libraries do not provide point location conversion events, and the previous route track cannot be cleared; 2. when the previous route track is cleared, the current route track is already drawn and is cleared. To solve the problems in the prior art and the problems originally conceived by the inventors, embodiments of the present invention provide the following solutions.

Fig. 1 is a flowchart of steps of a trajectory mapping method provided by an embodiment of the present invention, where the method may be executed by an electronic device such as a computer, as shown in fig. 1, and the method may include:

step 101, obtaining historical marking points and marking time corresponding to a person of a track to be drawn.

The historical marking point is a coordinate point of a camera of the person on the map, and the marking time is the time of the camera capturing the person.

After the pictures are captured by the cameras arranged in the preset area, people in each picture are determined by carrying out face recognition on each picture, and when the same person is included in the pictures, the historical track of the person can be drawn so as to know the historical track of the person. In order to draw the historical track of the personnel, determining a camera and shooting time of the personnel, taking the coordinate point position of the camera on a map as the historical marking point of the personnel, and taking the shooting time of the personnel as the marking time corresponding to the historical marking point.

In an embodiment of the present invention, the obtaining of the historical annotation point and the annotation time corresponding to the person who wants to draw the trajectory includes: acquiring a history snapshot picture and a corresponding camera mark; carrying out face recognition on the historical snap pictures, and determining the historical snap pictures including the personnel as track pictures; determining a camera identification corresponding to the track picture, and determining an initial marking point corresponding to the track picture according to the camera identification; taking the shooting time of the track picture as the marking time corresponding to the initial marking point; if two or more adjacent initial labeling points in the initial labeling points are the same, combining the two or more adjacent initial labeling points to obtain the historical labeling points corresponding to the personnel, and determining the labeling time corresponding to the combined historical labeling points according to the labeling time corresponding to the two or more adjacent initial labeling points.

The history snapshot picture in the appointed time period can be obtained, and the camera identification corresponding to the camera shooting the history snapshot picture is determined to be used as the camera identification corresponding to the history snapshot picture. And carrying out face recognition on the historical snap pictures, determining the historical snap pictures comprising the personnel, and taking the historical snap pictures comprising the personnel as track pictures. The position of each camera on the map is fixed, so that the initial marking point corresponding to the track picture can be determined according to the camera identification, namely, the coordinate point position corresponding to the camera identification for shooting the track picture is used as the initial marking point corresponding to the track picture. The personnel can stop in a certain position, therefore, the camera of same position can be taken a candid photograph many times personnel, in order to avoid appearing in the phenomenon that a mark point pauses when drawing the orbit, can go on the initial mark point to coincide and handle, be about to two or more adjacent initial mark points that are the same merge into a mark point, merge the back to all initial mark points, obtain the historical mark point that personnel correspond. After two or more adjacent initial labeling points are combined into one historical labeling point, the labeling time corresponding to any one of the two or more adjacent initial labeling points can be used as the labeling time corresponding to the historical labeling point.

Through carrying out de-coincidence and processing on the initial labeling points, two adjacent history labeling points in the obtained history labeling points are different, so that the phenomenon that the same history labeling point is stuck cannot occur in the subsequent history track drawing process, and the animation continuity of track drawing is ensured.

And step 102, sequentially selecting two adjacent historical marking points from the historical marking points according to the marking time sequence to serve as a current drawing marking point, and determining a drawing starting point and a drawing ending point in the current drawing marking point.

The history marking points can be arranged according to the sequence of the marking time, so that two adjacent history marking points can be sequentially selected according to the arrangement sequence to serve as a current drawing marking point, a previous history marking point in the two adjacent history marking points serves as a drawing starting point, and a next history marking point in the two adjacent history marking points serves as a drawing ending point.

For example, if the history annotation points arranged according to the annotation time sequence include A, B, C, D, the two adjacent history annotation points selected for the first time are a and B, the two adjacent history annotation points selected for the second time are B and C, and the two adjacent history annotation points selected for the third time are C and D.

And 103, determining the drawing time corresponding to the current drawing annotation point.

And the drawing time is the drawing time required for currently drawing the route track between the labeling points.

The drawing time of the route track corresponding to each two adjacent historical annotation points can be the same or different. For example, the drawing time corresponding to the current drawing annotation point can be determined according to the attention level corresponding to the current drawing annotation point, and the drawing time set by the user can be received in real time as the drawing time corresponding to the current drawing annotation point. The drawing time may be, for example, 3 seconds, 4 seconds, 5 seconds, or the like.

In an embodiment of the present invention, the determining a drawing time corresponding to the current drawing annotation point optionally includes: determining the attention level corresponding to the current drawing marking point; and determining the drawing time corresponding to the current drawing annotation point according to the attention level and a preset corresponding relation between the attention level and the drawing time, wherein in the corresponding relation, the drawing time corresponding to the attention level is from long to short according to the sequence from high to low of the attention level.

The coordinate points where the cameras are located can be classified in advance, that is, corresponding attention levels can be set for the positions of the cameras, for example, three levels of focus attention, general attention and no attention can be set, and other levels can be set according to needs. And the current drawing and labeling point comprises a drawing starting point and a drawing ending point, attention levels of the drawing starting point and the drawing ending point are respectively determined, and an attention level with a higher attention level in the drawing starting point and the drawing ending point is used as an attention level corresponding to the current drawing and labeling point. And storing the corresponding relation between the attention level and the drawing time in advance, inquiring the corresponding relation after determining the attention level corresponding to the current drawing attention, and taking the drawing time corresponding to the determined attention level as the drawing time of the current drawing annotation point. According to the sequence of the attention levels from high to low, the drawing time corresponding to the attention levels is from long to short, and when the historical tracks corresponding to the marking points with higher attention levels are drawn, the drawing time is longer, so that the user can focus on the tracks.

When the attention level corresponding to the historical annotation point is low, the historical annotation point can be deleted, that is, the historical annotation point with low attention level is not embodied. For example, if the attention level of one history annotation point is attention-free, the history annotation point with the attention level of attention-free can be deleted when the history annotation point is determined.

In an embodiment of the present invention, after determining the attention level corresponding to the current drawing annotation point, the method may further include: and acquiring a prompt tone corresponding to the attention level, and playing the prompt tone.

The user can also preset a prompt tone corresponding to the attention level, after the attention level corresponding to the current drawing marking point is determined, the prompt tone corresponding to the attention level is obtained, and the prompt tone is played, so that the user can be reminded to pay attention to the track being drawn.

And 104, displaying the drawing starting point and the drawing ending point on a map respectively, and drawing the current route track of the personnel from the drawing starting point to the drawing ending point on the map according to the drawing time, wherein if the previous route track exists during drawing the current route track, the previous route track is removed, and then the current route track is drawn.

After determining a drawing starting point and a drawing marking point in the current drawing marking point, the drawing starting point and the drawing ending point are displayed differently from the historical marking points which are not drawn, and the drawing starting point and the drawing ending point can also be displayed identically with the historical marking points which are drawn, so that the current drawing marking point and the marked points which are drawn are displayed differently from the historical marking points which are not drawn, and a user can know the marking points which are drawn. For example, the drawn history annotation point and the current drawing annotation point are highlighted.

And determining the current drawing speed according to the drawing time corresponding to the current drawing marking point and the distance between the current drawing marking points, and calling a track processing function to draw the current route track of the person from the drawing starting point to the drawing ending point on the map at the current drawing speed. If the last route track exists during the drawing of the current route track, namely the route track with the drawing starting point in the current drawing marking point as the end point exists, the current route track is drawn after the last route track is cleared, the track displayed on the map is ensured to only keep the currently drawn route track, the problem that track grids are formed by the tracks in a crossed mode is solved, the track processing function corresponding to the last route track is destroyed while the last route track is cleared, and the influence on the drawing of the current route track is avoided. And destroying the track processing function corresponding to the previous route track, namely deleting all instances created by the track processing function when the previous route track is drawn, or setting the instances created by the track processing function when the previous route track is drawn to be null.

In the embodiment of the invention, a track processing function is called once when a route track is drawn, namely, after a current drawn marking point to be drawn is determined, the track processing function is called to draw the track of the current drawn marking point to obtain the current route track, after the current route track is drawn, when the next route track is drawn, the current route track is cleared, the track processing function for drawing the current route track is destroyed, and then the track processing function is called according to two marking points of the next route track to draw the next route track. That is, the annotation points transferred to the trajectory processing function each time are only two annotation points corresponding to the currently drawn route trajectory, not all annotation points, thereby improving the controllability of trajectory drawing.

As shown in fig. 2, the history annotation points include a history annotation point 1, a history annotation point 2 and a history annotation point 3, and when the route tracks from the history annotation point 2 to the history annotation point 3 are drawn, the route tracks from the history annotation point 1 to the history annotation point 2 are removed, so that the currently drawn route track is relatively clear, and the problem of unclear current route track caused by intersection with other route tracks is avoided.

And 105, judging whether the route tracks corresponding to the historical annotation points are drawn completely, if not, circularly executing the steps 102 to 105, and if so, ending.

And judging whether the route tracks corresponding to all the historical marking points are drawn or not, if all the route tracks corresponding to all the historical marking points are drawn, finishing the drawing, and if any route track corresponding to the historical marking points is not drawn, circularly executing the steps 102 to 105 until all the route tracks corresponding to all the historical marking points are drawn.

After the route tracks corresponding to all the history annotation points are completely drawn, a replay button can be displayed, and when the replay button is detected to be operated by the user, and a replay instruction is determined to be received, the drawing process of the tracks is replayed, namely, the steps 102 to 105 are executed again.

The method for drawing a historical track provided by this embodiment includes obtaining historical annotation points and annotation time corresponding to a person to be drawn a track, sequentially selecting two adjacent historical annotation points from the historical annotation points according to an annotation time sequence to serve as a current drawing annotation point, determining a drawing starting point and a drawing ending point in the current drawing annotation point, determining a drawing time corresponding to the current drawing annotation point, displaying the drawing starting point and the drawing ending point on a map in a distinguishing manner, drawing the current route track of the person from the drawing starting point to the drawing ending point according to the drawing time, and drawing the current route track after removing the previous route track if the previous route track exists during drawing the current route track, so that the track displayed on the map only keeps the current drawn route track, and the problem that a track grid is formed by mutual intersection between tracks is solved, the method and the device realize the clear representation of the walking route of the currently drawn track on the map, and improve the visual experience.

On the basis of the above technical solution, the method may further optionally include: and if the drawing time set by the user is received when the current route track of the person is drawn from the drawing starting point to the drawing ending point on the map, taking the received drawing time as the drawing time of the next route track of the current route track.

An interface for setting the drawing time by the user can be arranged on the map, and the drawing time set by the user is received through the interface. When the current route track of the personnel is drawn from the drawing starting point to the drawing ending point on the map, the user can also set the drawing time through the interface, and when the drawing time set by the user is received, the received drawing time is taken as the drawing time of the next route track of the current route track, so that when the next route track is drawn, the drawing time of the next route track is taken as the received drawing time, the drawing time is changed in the drawing process, the drawing speed is changed, and the requirements of different scenes can be met.

On the basis of the above technical solution, the method may further optionally include: and recording the drawing starting point and the drawing ending point when the current route track of the person is drawn from the drawing starting point to the drawing ending point on the map.

When the current route track is drawn on the map, the drawing starting point and the drawing ending point corresponding to the current route track are recorded, and when an abnormal condition occurs, the drawing can be redrawn according to the drawing starting point and the drawing ending point without starting from the first historical marking point, and the drawing can be suspended according to the instruction of a user.

On the basis of the above technical solution, the method may further optionally include: and if an error occurs when the current route track of the person is drawn from the drawing starting point to the drawing ending point on the map, redrawing the current route track from the drawing starting point to the drawing ending point on the map according to the recorded drawing starting point and the recorded drawing ending point.

If an error occurs in the process of drawing the current route track from the drawing starting point to the drawing ending point on the map, such as network disconnection, the error is captured, a corresponding log is recorded, and the current route track is redrawn from the drawing starting point to the drawing ending point after the error is corrected, so that the redrawing from the first historical marking point is not needed when the error is encountered in the track drawing process, the redrawing is started only from the route track when the error is encountered, the track drawing time when the error is encountered is saved, and the effect of reducing the user perception of the abnormality is achieved.

On the basis of the above technical solution, the method may further optionally include: when the current route track of the person is drawn from the drawing starting point to the drawing ending point on the map, if a drawing pause instruction is received, the drawing is paused after the current route track is drawn; and if a drawing starting instruction is received, drawing the next route track from the recorded drawing termination point.

The method comprises the steps that in the process of drawing a current route track from a drawing starting point to a drawing ending point on a map, a user can pause drawing, when an electronic device executing the historical track drawing method receives a drawing pause instruction, the current route track is drawn completely, drawing is paused after the current route track is drawn completely, and the current route track is displayed on the map, so that the user can visually watch the current route track. After the drawing is suspended, the user can restart the drawing, and after the electronic equipment executing the historical track drawing method receives a drawing starting instruction, the electronic equipment starts to draw the next route track from the recorded drawing termination point and clears the current route track. The purpose of pausing and continuing to draw the historical track in the drawing process of the historical track is achieved by drawing the track between the two marked points one by one and recording the current drawing position.

When the current drawing marking point is determined, two adjacent historical marking points are sequentially selected from the point location list according to the marking time sequence.

For example, A, B, C, D is the history annotation point determined at the beginning, the four history annotation points are added into the point location list according to the annotation time sequence, two adjacent history annotation points selected from the point location list for the first time are A and B, and a route track from A to B is drawn; after the route track from A to B is drawn, two adjacent historical marking points selected from the point location list for the second time are B and C, the route track from B to C is drawn, when the route track from B to C is drawn, a new historical marking point E is obtained, the new historical marking point E is added into the point location list, and after D; after the route track from B to C is drawn, selecting two adjacent historical marking points C and D from the point location list for the third time, and drawing the route track from C to D; and after the route track from the C to the D is drawn, selecting two adjacent historical marking points D and E from the point location list for the fourth time, and drawing the route track from the D to the E.

And step 304, determining the drawing time corresponding to the current drawing annotation point.

And 305, displaying the drawing starting point and the drawing ending point on a map respectively, and drawing the current route track of the person from the drawing starting point to the drawing ending point on the map according to the drawing time, wherein if the previous route track exists during drawing the current route track, the previous route track is removed, and then the current route track is drawn.

Step 306, in the process of drawing the current route track, if new historical marking points and marking time are obtained, adding the new historical marking points and marking time to the point location list.

In the process of drawing the current route track, new historical marking points and marking time can be obtained, the obtained new historical marking points and marking time are added into the point location list, the route track corresponding to the new historical marking points is added on the basis of the original route track, and the dynamic state of personnel can be monitored in real time.

And 307, judging whether the route tracks corresponding to the historical annotation points are drawn completely, if not, circularly executing the step 303 to the step 307, and if so, ending the step.

According to the historical track drawing method provided by the embodiment, the obtained historical annotation point is added into the point location list, and the historical annotation point is taken from the point location list for drawing when the track is drawn, so that in the process of drawing the current route track, if a new historical annotation point is obtained, the new historical annotation point can be added into the point location list, thereby realizing dynamic addition of the historical annotation point and dynamic drawing of the route track, and meeting the requirement of real-time monitoring.
