Based on the above hardware structure, the embodiment of the monitoring and tracking method is provided, the monitoring and tracking method is applied to the monitoring and tracking system of the smart home scene, and for convenience of description, the monitoring and tracking system is simply called a monitoring system.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a monitoring and tracking method according to the present invention, the method includes:
Step S10, if a person to be tracked is acquired through a camera, a monitoring system determines a target scene where the person to be tracked is located and 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;
In 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 the preset terminal.
In smart home scenes, a camera is often used for identifying and caring indoor people of a household, when the camera is set in a caring mode, namely a monitoring mode, the camera in a traditional mode is only used as an identification mode according to image changes at a certain place in a video, when the monitoring video changes for a plurality of times, the camera cannot make a decision, namely when a plurality of target people are identified, the camera cannot preferentially identify the target people focused by a user, and even because of untimely response, the monitoring system collapses, so that data of key tracking people are lost.
The person in the home may be a person or an object such as a cat in the home.
According to the monitoring system, the camera is used for collecting the person to be tracked, and the target scene and corresponding behavior information of the person to be tracked are determined, 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 following will explain each step in detail:
Step S10, if a person to be tracked is acquired through a camera, a monitoring system determines a target scene where the person to be tracked is located and behavior information of the person to be tracked in the target scene;
In this embodiment, cameras are installed in advance in each scene to be monitored, and the monitoring system stores monitoring videos collected in advance by each camera. 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 of the people to be tracked through the camera, and then acquire the monitoring video of the people to be tracked in the target scene, so that the respective behavior information of the people to be tracked is determined. Wherein, the scene includes room, living room etc.
Specifically, step S10 includes:
Step a1, a monitoring system determines the position of a camera, and determines a target scene where a person to be tracked is located 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 face recognition and other modes, 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 collects the person to be tracked is located, that is, the scene where the camera collects the person to be tracked is the target scene where the person to be tracked is located, if the current camera is installed in a study, then the target scene where the person to be tracked is determined to be the study.
Step a2, the monitoring system acquires a pre-acquired character group of the target scene, and determines behavior information of the character to be tracked in the target scene according to the pre-acquired character group.
In this embodiment, the pre-collection character set exists before the current camera collects the character to be tracked. Before the camera is used for collecting, 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 person videos or pictures into corresponding people groups by screening the collected monitoring videos, so that a pre-collected person group is formed on the basis. That is, before the current camera collects, the people appearing in each scene can find a dedicated person group, that is, a pre-collected person group, in each scene in the monitoring system. Therefore, the monitoring system can determine the identity of the person to be tracked by acquiring the pre-acquired person group of the target scene, so as to determine the behavior information of each person to be tracked in the target scene.
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 corresponding person group does not need to be acquired to determine the priority order; if the monitoring system cannot acquire a 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 set for the character group through acquisition and screening of the camera, 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 order of the people to be tracked through the conditions of the target scene where the people to be tracked are located, the corresponding behavior information of each person to be tracked, and the like, so as to determine the target people in the people to be tracked.
Specifically, step S20 includes:
step b1, the monitoring system calculates the occurrence percentage and the time percentage of the person A to be tracked according to the occurrence times and the residence time of the person A to be tracked of a 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 people to be tracked is greater than or equal to two, and the behavior information includes the number of occurrences and the retention time, then in the process of determining the target people, the monitoring system may obtain the number of occurrences and the retention time of each person to be tracked in the target scene by obtaining the behavior information of each person to be tracked, calculate the sum of the number of occurrences and the sum of the retention time of each person to be tracked, thereby determining the total number of occurrences and the total retention time of each person to be tracked in the target scene, and finally calculate the percentage of occurrences and the percentage of time of each person to be tracked.
Taking any one of at least two people to be tracked as a person A to be tracked as an example, the monitoring system calculates the occurrence percentage and the time percentage of the person A to be tracked according to the occurrence times and the stay time of the person A to be tracked in the target scene.
Specifically, the calculation formula of the occurrence percentage of the person to be tracked a is:
percentage occurrence = number of occurrences/total number of occurrences x 100%
That is, the number of occurrences of the person to be tracked a in the target scene is divided by the total number of occurrences of all the persons to be tracked in the target scene.
The calculation formula of the percentage of time of the person A to be tracked is as follows:
percent time = residence time/total residence time x 100%
That is, the dwell time of the person to be tracked a in the target scene is divided by the total dwell 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 occurrence 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 time percentage, and specifically, the calculation formula of the priority percentage is as follows:
priority percentage = percentage of occurrence + percentage of time
That is, the percentage of appearance of the person to be tracked a is added to the percentage of time to obtain the priority percentage of the person to be tracked a.
In this way, the priority percentages of the individual persons to be tracked are determined in turn.
And b3, determining target characters in the characters to be tracked by the monitoring system according to the priority percentage of each of the at least two characters to be tracked.
In this embodiment, the monitoring system calculates the sum of the occurrence percentage and the time percentage to determine the priority percentage of each person to be tracked, and arranges the priority percentages in a descending order or an ascending order, so as to discharge the priority orders of the persons to be tracked in a one-to-one correspondence manner, thereby determining the target person in the persons to be tracked, wherein in the implementation, the monitoring system may determine the person to be tracked with the front priority order as the target person, or may determine the person to be tracked with the rear priority order as the target person.
In 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 the preset terminal.
In this embodiment, the monitoring system is connected to the preset terminal in advance, and after determining the target person in each scene, 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 of the person to be tracked 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, and the picture finally presented by the camera is ensured to be a picture which a user cares about wanted, so that intelligent monitoring is realized.
Further, based on the first embodiment of the monitoring and tracking method of the present invention, a second embodiment of the monitoring and tracking method of the present invention is provided.
The second embodiment of the monitoring and tracking method differs from the first embodiment of the monitoring and tracking method in that step S20 includes:
Step c, the monitoring system calculates the time percentage of the person B to be tracked according to the stay 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;
step d, the monitoring system determines the priority proportion of the person B to be tracked according to the time percentage of the person B to be tracked and the clicking times of the person B to be tracked in the target scene;
Step e, the monitoring system determines the priority sequence of at least two people to be tracked according to the priority proportion of each of the at least two people to be tracked;
and f, determining target characters in the characters to be tracked by the monitoring system according to the priority order.
In the monitoring and tracking method of the embodiment, if the number of the people to be tracked is greater than or equal to two in the process of determining the target people, and the behavior information comprises the stay time and the click times, the monitoring system can acquire the stay time and the click times of each person to be tracked in the target scene by acquiring the behavior information of each person to be tracked in the process of determining the target people, so that the target people in the people to be tracked are determined.
It should be noted that the clicking times refer to the clicking times counted by the monitoring system for each person in the monitoring picture by clicking the monitoring picture displayed by the preset terminal by the user before the current camera is used for collecting. That is, when the monitoring screen is displayed on the preset terminal, the user can select the monitoring object by clicking the person in the monitoring screen, that is, the switching tracking of the target person is realized, and the more the number of times the user clicks, the corresponding clicked object is the target person which the user wants to track on the surface.
The following will explain each step in detail:
Step c, the monitoring system calculates the time percentage of the person B to be tracked according to the stay 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, determining a target scene where the person to be tracked is located through a camera, acquiring behavior information of each person to be tracked, namely acquiring the retention time and the clicking times of each person to be tracked, respectively calculating the sum of the retention time and the clicking times of each person to be tracked in the target scene, thereby determining the total retention time and the total clicking times of each person to be tracked in the target scene, finally obtaining the time percentage and the clicking percentage of each person to be tracked through calculation, and determining the priority ratio of each person to be tracked through calculating the sum of the corresponding time percentage and the clicking percentage of each person to be tracked.
Taking the person to be tracked B as an example, the person to be tracked B is any one of at least two persons to be tracked, the monitoring system calculates the time percentage of the person to be tracked B according to the stay time of the person to be tracked B in the target scene, and the specific calculation mode is consistent with the time percentage calculation mode of the first embodiment, which is not described herein, wherein the person to be tracked B is one of the at least two persons to be tracked.
Step d, the monitoring system determines the priority proportion of the person B to be tracked according to the time percentage of the person B to be tracked and the clicking times of the person B to be tracked in the target scene;
then, the monitoring system determines the click percentage of the person to be tracked B according to the click times of the person to be tracked B in the target scene, wherein the specific calculation formula is as follows:
percentage of clicks = number of clicks/total number of clicks x 100%
The number of clicks of each person to be tracked in at least two persons to be tracked is determined, so that the total number of clicks is obtained by adding, and the number of clicks of the person to be tracked B is divided by the total number of clicks to obtain the percentage of clicks of the person to be tracked.
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 = percentage of time + percentage of click
In this way, the priority ratio of each of the at least two persons to be tracked is sequentially calculated
And e, determining the priority sequence of the at least two persons to be tracked according to the priority proportion of each of the at least two persons to be tracked by the monitoring system.
In this embodiment, the priority ratios of the persons to be tracked are arranged in a descending order or an ascending order, so as to correspondingly discharge the priority sequences of at least two persons to be tracked in the target scene.
And f, determining target characters in the characters to be tracked by the monitoring system according to the priority order.
Finally, the monitoring system determines a target person in the persons to be tracked according to the priority order, and in specific implementation, the person to be tracked with the forefront priority order, such as the person B to be tracked, is taken as the target person; the person to be tracked with the last priority sequence, such as the person to be tracked A, can be used as the target person, etc.
According to the monitoring and tracking method, the camera is used for collecting the person to be tracked, the target scene where the person to be tracked is located and corresponding behavior information are determined, so that the stay time and the clicking times of the person to be tracked in the target scene are determined, the target person to be tracked by the camera is determined by determining the priority sequence of each person to be tracked, the camera is controlled to monitor the target person, and the system is ensured not to lose the target person.
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 acquires a 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 the priority order according to the target scene, and determines the next target person monitored and tracked by the camera according to the priority order.
After determining the target person to be monitored and tracked, if the camera detects that the target person leaves the target scene, the monitoring system of the embodiment updates the person group corresponding to the target person, and determines the next target person to be monitored and tracked by the camera by acquiring the priority of the person to be tracked in the target scene.
The following will explain each step in detail:
step g, if the target person is detected to leave the target scene, the monitoring system acquires a 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 acquired, 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 the priority order according to the target scene, and determines the next target person monitored and tracked by the camera according to the priority order.
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 redetermined according to the priority order.
According to the monitoring tracking method, 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, based on the first, second and third embodiments of the positioning method of the present invention, a fourth embodiment of the positioning method of the present invention is provided.
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 acquires a second updating time corresponding to the target scene;
Step j, the monitoring system determines the switching time of the target person according to at least two persons to be tracked and the second updating time;
and k, the monitoring system controls the cameras to sequentially switch and monitor and track the target person according to the switching time and the priority order.
The monitoring system of the embodiment determines the switching time of the cameras by acquiring the second updating time corresponding to the target scene and at least two people to be tracked, and controls the cameras to sequentially switch the target people according to the priority order of the people to be tracked in the target scene.
The following will explain each step in detail:
Step i, the monitoring system acquires a second updating time corresponding to the target scene;
In this embodiment, after the target person is determined, a corresponding second update time of the target scene is acquired, 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 time of the other scenes.
Step j, the monitoring system determines the switching time of the target person according to at least two persons to be tracked and the second updating time;
in this embodiment, the switching time of the camera to switch the tracked target person 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 of the camera for switching the target person is as follows:
switching time = second update time/number of people
That is, each person to be tracked enjoys the same shot time, and therefore, the switching time of each person to be tracked can be obtained by dividing the second update time by the number of the persons.
And k, the monitoring system controls the cameras to sequentially switch and monitor and track the target person according to the switching time and the priority order.
In this embodiment, if it is detected that the switching time of the cameras in the target scene is up, the priority order of the people to be tracked is obtained, and the cameras are controlled to switch the target people in sequence. For example, if the people to be tracked acquired by the camera at this time have 3 people including dad, mom and dad, the target scene is living room, the second update time of the living room is 60 minutes, then the switching time of the camera in the living room is 60/3=20 minutes, that is, the camera switches the tracked target people every 20 minutes, and meanwhile, the priority order of the people in the living room is known to be the dad, the dad and the dad, then the target people tracked by the camera are the dad, the dad and the dad pass 20 minutes, the monitoring system controls the camera to switch and track the mom, the dad is switched and tracked by the camera for 20 minutes, and the camera is switched and tracked by the dad for 20 minutes.
According to the monitoring tracking method, after the priority sequence 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 sequence of the people to be tracked and the switching time, and the tracked target people are flexibly switched and tracked.
Further, based on the first, second, third and fourth embodiments of the positioning method of the present invention, a fifth embodiment of the positioning method of the present invention is provided.
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 includes:
