In the monitor tracing system shown in fig. 1, a monitor tracing program stored in a memory 1005 is called by a processor 1001, and the operations in the embodiments of the monitor tracing method described below are performed.
Based on the above hardware structure, an embodiment of the monitoring and tracking method of the present invention is provided, where the monitoring and tracking method is applied to a monitoring and tracking system for smart home scenes, and for convenience of description, the monitoring and tracking system is referred to as a monitoring system for short.
Referring to fig. 2, fig. 2 is a schematic flow chart of a monitoring and tracking method according to a first embodiment of the present invention, the method including:
step S10, if the person to be tracked is acquired through the camera, the monitoring system determines the target scene where the person to be tracked is located and the behavior information of the person to be tracked in the target scene;
step S20, the monitoring system determines a target person in the persons to be tracked according to the target scene and the behavior information;
and step S30, the monitoring system controls the camera to monitor and track the picture of the target person and displays the monitored and tracked picture of the target person on a preset terminal.
In an intelligent home scene, a camera is often used for identifying and caring people in a home, when a camera in a home is set to be in a caring mode, namely a monitoring mode, the camera in a traditional mode only takes image change at a certain position in a video as an identification mode, when the monitoring video changes for multiple times, the camera cannot make a decision, namely, when multiple target people are identified, the camera cannot preferentially identify the target people concerned by a user, even the monitoring system is broken down due to untimely response, so that data of key tracking people are lost.
It should be noted that the people in the family room may be people or objects, such as kittens in the family.
The monitoring system of the embodiment acquires the person to be tracked through the camera, and determines the target scene where the person to be tracked is located and the corresponding behavior information, so that the tracked target person is determined, the camera is controlled to monitor the target person, and the system is ensured not to lose the target person which the user wants to pay attention to.
The respective steps will be described in detail below:
step S10, if the person to be tracked is acquired through the camera, the monitoring system determines the target scene where the person to be tracked is located and the behavior information of the person to be tracked in the target scene;
in this embodiment, cameras are installed in each scene to be monitored in advance, and the monitoring system stores monitoring videos collected by the cameras in advance. If the camera collects the people to be tracked, the people to be tracked can be identified according to the characteristics of different people, meanwhile, the monitoring system can determine the target scene where the people to be tracked are located through the camera, and then the monitoring video of the people to be tracked in the target scene is obtained, so that the respective behavior information of the people to be tracked is determined. Wherein, the scene comprises a room, a living room and other spaces.
Specifically, step S10 includes:
step a1, the monitoring system determines the position of the camera, and determines the target scene of the person to be tracked according to the position of the camera;
in this embodiment, if the camera collects the person to be tracked, person identification can be performed through modes such as face identification, and meanwhile, the monitoring system can determine the target scene where the person to be tracked is located by determining the specific position where the camera collecting the person to be tracked is located, that is, the scene where the camera collecting the person to be tracked is located is the target scene where the person to be tracked is located, and if the current camera is installed in a study room, it is determined that the target scene where the person to be tracked is located is the study room.
Step a2, the monitoring system obtains a pre-collected character group of the target scene, and determines the behavior information of the character to be tracked in the target scene according to the pre-collected character group.
In this embodiment, the pre-capture people group is already present before the camera captures the people to be tracked. Before this camera collection, the monitoring system identifies people in each indoor scene through the camera, sets corresponding people groups for different people identified in each scene, and records collected people videos or pictures into corresponding people groups through screening collected monitoring videos, so that pre-collected people groups are formed on the basis. That is to say, before the camera is used for capturing, people appearing in each scene can find an exclusive people group in each scene in the monitoring system, that is, the people group is captured in advance. Therefore, the monitoring system can determine the identity of the people to be tracked by acquiring the pre-acquired people group of the target scene, so that the behavior information of each person to be tracked in the target scene is determined.
It should be noted that, if there is only one person to be tracked, the person to be tracked is the target person, and the priority order is not determined by obtaining the corresponding person group; if the monitoring system cannot acquire the pre-acquired character group of a certain character to be tracked in the target scene, the character to be tracked is a new character of the target scene, and the new character group can be acquired and screened through the camera and set for the new character group, so that the character group of the new character is blank at first, and all behavior information is zero.
Step S20, the monitoring system determines a target person in the persons to be tracked according to the target scene and the behavior information;
in this embodiment, the monitoring system determines the priority of the people to be tracked according to the target scene where the people to be tracked are located, the behavior information corresponding to each person to be tracked, and the like, so as to determine the target people among the people to be tracked.
Specifically, step S20 includes:
b1, calculating the appearance percentage and the time percentage of the person A to be tracked by the monitoring system according to the appearance times and the stay time of the person A to be tracked in the target scene, wherein the person A to be tracked is any one of at least two persons to be tracked;
in this embodiment, if the number of the people to be tracked is greater than or equal to two, and the behavior information includes the occurrence number and the staying time, the monitoring system may obtain the occurrence number and the staying time of each person to be tracked in the target scene by obtaining the behavior information of each person to be tracked in the process of determining the target person, determine the total occurrence number and the total staying time of the person to be tracked in the target scene by calculating the total occurrence number and the total staying time of the person to be tracked, and finally obtain the occurrence percentage and the time percentage of each person to be tracked by calculating.
Taking any one of at least two people to be tracked as the person A to be tracked as an example, the monitoring system respectively calculates the occurrence percentage and the time percentage of the person A to be tracked according to the occurrence frequency and the stay time of the person A to be tracked in the target scene.
Specifically, the calculation formula of the appearance percentage of the person a to be tracked is as follows:
the percentage of appearance is the number of appearance times/total number of appearance times x 100%
That is, the number of times the person a to be tracked appears in the target scene is divided by the total number of times all the persons to be tracked appear in the target scene.
The calculation formula of the time percentage of the person A to be tracked is as follows:
the percentage of time is residence time/total residence time x 100%
That is, the stay time of the person a to be tracked appearing in the target scene is divided by the total stay time of all the persons to be tracked in the target scene.
Step b2, the monitoring system determines the corresponding priority percentage of the person A to be tracked according to the appearance percentage and the time percentage of the person A to be tracked;
then, the monitoring system determines the priority percentage of the person a to be tracked according to the determined occurrence percentage and the time percentage, and specifically, the calculation formula of the priority percentage is as follows:
priority percentage is the percentage of appearance + percentage of time
That is, the priority percentage of the person a to be tracked can be obtained by adding the appearance percentage of the person a to be tracked to the time percentage.
The priority percentages of the various people to be tracked are determined in turn in this manner.
And b3, the monitoring system determines the target person in the people to be tracked according to the priority percentage of each person to be tracked in at least two people to be tracked.
In this embodiment, the monitoring system determines the priority percentages of the persons to be tracked by calculating the sum of the appearance percentages and the time percentages, arranges the priority percentages in a descending or ascending manner, and arranges the priority orders of the persons to be tracked in a one-to-one correspondence manner, thereby determining the target person among the persons to be tracked, wherein in specific implementation, the monitoring system may determine the person to be tracked with the highest priority order as the target person, or may determine the person to be tracked with the highest priority order as the target person.
And step S30, the monitoring system controls the camera to monitor and track the picture of the target person and displays the monitored and tracked picture of the target person on a preset terminal.
In this embodiment, the monitoring system is connected to the preset terminal in advance, after the target person in each scene is determined, the monitoring system controls the camera in the target scene to monitor and track the target person, that is, where the target person moves, and the monitoring system can control where the camera turns and display the monitoring picture of the monitored and tracked target person in the preset terminal.
According to the monitoring and tracking method, if the person to be tracked is acquired through the camera, the target person in the person to be tracked is determined by determining the target scene where the person to be tracked is located and the behavior information of the person to be tracked in the target scene, so that the camera is controlled to monitor and track the target person, the camera cannot lose the target person due to interference of other moving objects, the picture finally presented by the camera is ensured to be a picture which a user cares about to want, and intelligent monitoring is achieved.
Further, a second embodiment of the monitoring and tracking method of the present invention is provided based on the first embodiment of the monitoring and tracking method of the present invention.
The second embodiment of the monitor tracing method is different from the first embodiment of the monitor tracing method in that the step S20 includes:
step c, the monitoring system calculates the time percentage of the person B to be tracked according to the staying time of the person B to be tracked in the target scene, wherein the person B to be tracked is any one of at least two persons to be tracked;
d, the monitoring system determines the priority ratio of the person B to be tracked according to the time percentage of the person B to be tracked and the click times of the person B to be tracked in the target scene;
e, the monitoring system determines the priority order of at least two people to be tracked according to the priority proportion of each person to be tracked in the at least two people to be tracked;
and f, determining a target person in the persons to be tracked by the monitoring system according to the priority.
In the monitoring and tracking method of the embodiment, in the process of determining the target person, if the number of the persons to be tracked is greater than or equal to two and the behavior information includes the staying time and the number of clicks, the monitoring system may obtain the staying time and the number of clicks of each person to be tracked in the target scene by obtaining the behavior information of each person to be tracked in the process of determining the target person, so as to determine the target person in the persons to be tracked.
It should be noted that the number of clicks refers to the number of clicks respectively counted by the monitoring system for each person in the monitoring picture when the user clicks the monitoring picture displayed by the preset terminal before the camera collects the current time. That is, when the preset terminal displays the monitoring picture, the user can select the monitoring object by clicking the character in the monitoring picture, that is, the switching tracking of the target character is realized, and the more times the user clicks, the corresponding clicked object is the target character which the user wants to track on the surface.
The respective steps will be described in detail below:
step c, the monitoring system calculates the time percentage of the person B to be tracked according to the staying time of the person B to be tracked in the target scene, wherein the person B to be tracked is any one of at least two persons to be tracked;
in this embodiment, a target scene where people to be tracked are located is determined through a camera, behavior information of each person to be tracked is obtained, that is, the staying time and the click times of each person to be tracked are obtained, the total staying time and the total click times of each person to be tracked in the target scene are determined by respectively calculating the sum of the staying time and the sum of the click times of each person to be tracked in the target scene, finally, the time percentage and the click percentage of each person to be tracked are obtained through calculation, and the priority proportion of each person to be tracked is determined by calculating the sum of the corresponding time percentage and the click percentage of each person to be tracked.
Taking the person B to be tracked as an example, the person B to be tracked is any one of at least two persons to be tracked, the monitoring system calculates the time percentage of the person B to be tracked according to the staying time of the person B to be tracked in the target scene, and the specific calculation method is the same as the time percentage calculation method of the first embodiment, which is not described herein again, wherein the person B to be tracked is one of at least two persons to be tracked.
D, the monitoring system determines the priority ratio of the person B to be tracked according to the time percentage of the person B to be tracked and the click times of the person B to be tracked in the target scene;
then, the monitoring system determines the click percentage of the person B to be tracked according to the click times of the person B to be tracked in the target scene, and the specific calculation formula is as follows:
click percentage is click times/total click times x 100%
That is, the click times of each of the at least two to-be-tracked persons are determined, and then added to obtain the total click times, and the click times of the to-be-tracked person B is divided by the total click times, so that the click percentage of the to-be-tracked person is obtained.
And finally, the monitoring system determines the priority proportion of the person B to be tracked according to a preset formula, wherein the preset formula is as follows:
priority ratio time percent + click percent
In this way, the priority ratio of each person to be tracked in at least two persons to be tracked is calculated in turn
And e, the monitoring system determines the priority order of the at least two people to be tracked according to the priority proportion of each person to be tracked in the at least two people to be tracked.
In this embodiment, the priority ratios of the people to be tracked are arranged in a descending order or an ascending order, and the priority order of at least two people to be tracked in the target scene is correspondingly arranged.
And f, determining a target person in the persons to be tracked by the monitoring system according to the priority.
Finally, the monitoring system determines a target person in the persons to be tracked according to the priority, and in the specific implementation, the person to be tracked with the top priority, such as the person B to be tracked, can be used as the target person; the person to be tracked with the highest priority, such as the person a to be tracked, can also be used as the target person.
According to the monitoring and tracking method, the to-be-tracked person is acquired through the camera, the target scene where the to-be-tracked person is located and the corresponding behavior information are determined, so that the stay time and the click times of the to-be-tracked person in the target scene are determined, the target person to be tracked by the camera is determined by determining the priority order of each to-be-tracked person, the camera is controlled to monitor the target person, and the target person is prevented from being lost by a system.
Further, based on the first and second embodiments of the positioning method of the present invention, a third embodiment of the positioning method of the present invention is provided.
The third embodiment of the positioning method differs from the first and second embodiments of the positioning method in that, after step S30, the monitoring and tracking method further includes:
step g, if the target person is detected to leave the target scene, the monitoring system obtains first updating time, and updates the person group corresponding to the target person according to the first updating time;
and h, the monitoring system acquires a priority sequence according to the target scene and determines the next target person monitored and tracked by the camera according to the priority sequence.
After determining the target person to be monitored and tracked, if it is detected that the target person leaves the target scene through the camera, the monitoring system of this embodiment updates the person group corresponding to the target person, and determines the next target person to be monitored and tracked through the camera by obtaining the priority of the persons to be tracked in the target scene.
The respective steps will be described in detail below:
step g, if the target person is detected to leave the target scene, the monitoring system obtains first updating time, and updates the person group corresponding to the target person according to the first updating time;
in this embodiment, since the monitoring system controls the camera to track the target person in each scene, when the target person leaves the target scene, the first update time is obtained, and the behavior information of the target person in the target scene is updated, that is, the person group corresponding to the target person is updated.
And h, the monitoring system acquires a priority sequence according to the target scene and determines the next target person monitored and tracked by the camera according to the priority sequence.
In this embodiment, when the monitoring system detects that the target person leaves the target scene through the camera, the priority order of the current person to be tracked in the target scene is obtained, and the next target person tracked by the camera is determined again according to the priority order.
In the monitoring and tracking method of the embodiment, if the monitoring system detects that the target person leaves the target scene through the camera, the person group of the target person is updated, and the priority order of the current person to be tracked in the target scene is obtained, so that the next target person tracked by the camera is determined, and the monitoring system can flexibly switch the tracked object.
Further, a fourth embodiment of the positioning method of the present invention is provided based on the first, second, and third embodiments of the positioning method of the present invention.
The fourth embodiment of the positioning method differs from the first, second and third embodiments of the positioning method in that after step S30, the monitoring and tracking method further includes:
step i, the monitoring system obtains second updating time corresponding to a target scene;
j, the monitoring system determines the switching time of the target person according to the at least two persons to be tracked and the second updating time;
and step k, the monitoring system controls the camera to switch the monitoring tracking target person in sequence according to the switching time and the priority.
The monitoring system of this embodiment determines the switching time of the camera by obtaining the second update time corresponding to the target scene and at least two people to be tracked, and controls the camera to switch the target people in sequence according to the priority of the people to be tracked in the target scene.
The respective steps will be described in detail below:
step i, the monitoring system obtains second updating time corresponding to a target scene;
in this embodiment, after the target person is determined, a second update time corresponding to the target scene is obtained, where the second update time of the target scene may be set according to an actual situation, for example, 60min, and the second update time of the target scene may be the same as or different from the update times of other scenes.
J, the monitoring system determines the switching time of the target person according to the at least two persons to be tracked and the second updating time;
in this embodiment, the switching time for switching the tracked target person by the camera is determined by the preset updating time of the target scene and the number of persons to be tracked.
Specifically, the specific calculation formula of the switching time for switching the target person by the camera is as follows:
second update time/number of persons
That is, each person to be tracked enjoys the same shot time, so that the switching time of each person to be tracked can be obtained by dividing the second updating time by the number of persons.
And step k, the monitoring system controls the camera to switch the monitoring tracking target person in sequence according to the switching time and the priority.
In this embodiment, if it is detected that the switching time of the camera in the target scene is reached, the priority order of the people to be tracked is acquired, and the camera is controlled to switch the target people in sequence. For example, if the person to be tracked collected by the camera includes 3 people, namely, father, mom and brother, the target scene is the living room, and the second update time of the living room is 60 minutes, the switching time of the living room camera is 60/3-20 minutes, that is, the camera switches the tracked target person every 20 minutes, and meanwhile, the priority sequence of the person in the living room is known as brother, mom and father, so that the target person tracked by the camera is brother at the beginning and 20 minutes passes, the monitoring system controls the camera to switch and track mom, and then 20 minutes passes, the camera switches and tracks father and then 20 minutes passes, and the camera switches and tracks brother.
In the monitoring and tracking method of the embodiment, after the priority order of the people to be tracked in the target scene is determined, the switching time of the camera is determined, the people to be tracked are sequentially switched and tracked according to the priority order and the switching time of the people to be tracked, and the tracked target people are flexibly switched.
Further, a fifth embodiment of the positioning method of the present invention is provided based on the first, second, third, and fourth embodiments of the positioning method of the present invention.
The fifth embodiment of the positioning method differs from the first, second, third and fourth embodiments of the positioning method in that the monitoring and tracking method further comprises:
if the monitoring instruction of the preset terminal is detected, the monitoring system determines a target camera corresponding to the monitoring instruction;
