Specific embodiment

In order to better understand technical solution provided by the embodiments of the present application, below in conjunction with Figure of description and specifically Embodiment be described in detail.

In order to improve the efficiency of tracking target object, the embodiment of the present application provides a kind of method for tracking target object, under The application scenarios being related in face of the method for the tracking target object are introduced.

Fig. 1 is please referred to, includes but is not limited to including terminal device 11 and the first video camera 12, terminal device 11 in the scene Mobile phone, personal computer or tablet computer etc..First video camera 12 is the rotatable video camera of video camera, such as spherical camera Deng.Controller can be integrated in video camera, be also possible to be separately provided with video camera, be in Fig. 1 with controller collection at It is illustrated in the first video camera 12.

In practical applications, the range that user needs to monitor is larger, may install a video camera and not be able to satisfy family It needs, accordingly, it is possible to install multiple video cameras at home.Referring to figure 2., Fig. 2 be it is provided by the embodiments of the present application another Schematic diagram of a scenario includes terminal device 11, multiple first video cameras 12 and the second video camera 20 in the scene.

In application scenarios shown in Fig. 2, the second video camera 20 is used as main camera, and the first video camera 12 is used as from camera shooting Machine.Second video camera 20 for coordinating and managing multiple first video cameras 12, the first video camera 12 can with terminal device 11 into Row interaction, the second video camera 20 can also be interacted with terminal device 11.Between second video camera 20 and terminal device 11 Interaction message needs to share in some cases the first video camera 12.

Wherein, the number of the first video camera 12 is but not limit the first video camera 12 actually for 2 in Fig. 2 Number.

Below based on the application scenarios of Fig. 1, to the invention relates to a kind of tracking target object method progress It introduces.This method is executed by the controller in the first video camera 12, and controller can be central processing unit (Central Processing Unit, CPU), it is also possible to specific integrated circuit (Application Specific Integrated Circuit, ASIC), or be arranged to implement the embodiment of the present application one or more integrated circuits, such as: one or Multi-microprocessor (digital signal processor, DSP), or, one or more field programmable gate array (Field Programmable Gate Array, FPGA).

When user need to some target object carry out tracing and monitoring when, can be answered by the software in terminal device 11 Target following instruction is sent with to video camera 12, the controller in video camera 12 is according in target following instruction execution the application Tracking target object method.

For example, user worries, child or old man are in alone, worry that family has other strangers appearance or child Or there is uncomfortable situation in old man, user can send target following instruction to controller by terminal device, with instruction Controller carries out tracing and monitoring to the target object.

Below with reference to Fig. 3, the method that target object is tracked in the embodiment of the present application is introduced.

Step 301, the target object information that controller receiving terminal apparatus 11 is sent, target object information includes target pair The image of elephant.

Specifically, after user has just bought the first video camera 12 or user want for the first time to some target object or certain When a little target objects are monitored, which can be sent controller, controller by terminal device 11 by user Receive the target object information.

Wherein, target object can be understood as the object that user needs to be monitored.Target object information includes at least mesh Mark the image of object.For the ease of that can search for the accuracy rate of target object, the image of the target object can be target object Whole body images.Target object information can also include the type of target object and the title of target object.The class of target object Classification belonging to type such as target object, such as human or animal.The title of target object such as someone title etc..

Step 302, controller is that target object configures unique identification.

Specifically, controller after the target object information that receiving terminal apparatus 11 is sent, configures for the target object One unique identification.If there is multiple target objects, then a unique identification is configured for each target object.

Step 303, unique identification is sent to terminal device 11 by controller.

Specifically, controller is that after terminal device 11 configures unique identification, which is sent to terminal device 11. There may be multiple terminal devices 11 to send corresponding target object information, controller configures uniquely for each target object information After mark, corresponding unique identification is sent to each terminal device 11.

As one embodiment, after unique identification is sent to terminal device 11 by controller, user can pass through end End equipment 11 sends corresponding edit instruction to controller, and controller is after receiving edit instruction, according to the edit instruction Corresponding operation is carried out to each target object.

Specifically, referring to figure 4., edit instruction includes increasing instruction, deleting instruction and more new command.Below to controller The process of real-time three kinds of edit instructions is introduced.

When user wants to increase the target object of monitoring, it can be sent by terminal device 11 to controller and increase instruction, The information of increased target object is carried in increase instruction, after controller receives increase instruction, to increase in instruction Target object configure unique identification, be further continued for increase target object.

User wants the target object being arranged before deleting, and can send to controller and delete instruction, in deletion instruction The unique identification of some target object will be deleted by carrying instruction.Controller can be deleted after receiving deletion instruction according to this Except the information of corresponding target object is deleted in instruction.

User wants to update target object, more new command can be sent to controller, carrying instruction in more new command will be more The unique identification of some new target object.Controller, can be according to more new command update pair after receiving more new command The information for the target object answered.

It should be noted that controller can be the corresponding Permission Levels of multiple user configurations, each user can only be to certainly Target object in own permission is updated or deletes.

Step 304, controller generates monitoring information.

Generate a kind of mode of monitoring information are as follows:

According to image information, determine target object in the presetting bit set of each period；

Specifically, the first video camera 12 of rotation generally uses presetting bit technology, i.e., can be patrolled in multiple presetting bits Back rotation monitoring.In the case where user's specified progress tracing and monitoring to some target object, controller can control first The circuit in preset multiple presetting bits of video camera 12 shoots and records corresponding image letter while circuit Breath, image information include but is not limited to the image (image can be single picture or video) shot, image capturing time.Certainly Image information can also include the presetting bit at corresponding first video camera, 12 place of shooting image and the shooting of the first video camera 12 Parameter etc..

After recording image information, when controller can be real-time or be in idle condition, image information is analyzed, Generate corresponding monitoring information.Idle state can be understood as controller currently without the shape of the task of tracking target object monitoring State.Controller is illustrated according to the mode that image information generates monitoring information below.

After obtaining image information, a monitoring period can be divided into multiple periods by controller, to it is each when Between in section presetting bit of each target object in monitoring range analyzed, to obtain target object within each period Presetting bit set.

Wherein, corresponding duration of each period may be the same or different.Controller can be according to target object Behavior law divides the period, is also possible to what user manually set.Behavior law can be understood as target object at some Period may do same part thing, then can will do and be divided into a period this period that the event is spent.Such as One monitoring period is one day, can be divided into first time period 7-10 point, second time period 11-12 point, third time for one day Section 13-14, the 4th period 15-16, the 5th time 17-18 point, the 6th period 19-20, the 7th period 20-22, the 8th Period 22-6 point.

When recording the corresponding presetting bit of image in image information, control according to the image information, so that it may determine target pair As presetting bit corresponding within each period, and so on, target object is obtained in the presetting bit set of each period.When Controller storage target object be it is multiple, each target object is handled as procedure described above, obtains each target pair As the presetting bit set in each period.

When there is no the corresponding presetting bit of image in image information, figure can be calculated with the corresponding center point coordinate of image As corresponding presetting bit.

Specifically, prestoring reference point in the first video camera 12, such as using the initial touring point of the first video camera 12 as ginseng Origin is examined, since the first video camera 12 is usually to operate within the scope of certain angle along preset direction, 12 basis of the first video camera The central point of present image, reference point and velocity of rotation calculate the corresponding presetting bit of every image, and so on, obtain mesh Object is marked in the presetting bit set of each period.

Controller can the presetting bit set by target object, target object in each period be associated storage, obtain To monitoring information.In the embodiment of the present application, monitoring information includes at least target object and target object in each period Interior presetting bit set.

In a kind of possible embodiment, in a presetting bit, removed in the corresponding monitored picture of the first video camera 12 Target object may further include a lot of other objects, that is to say, that it is typically also to need that target object is searched in monitored picture Expend the regular hour.In order to save the time of later period search target object, in the embodiment of the present application, according to target object Presetting bit set within each period is below introduced the another way for generating monitoring information.

Generate a kind of mode of monitoring information are as follows:

Controller establishes the presetting bit set and target object of target object, target object within each period and exists The incidence relation of the corresponding reference scene element three of each presetting bit, the association are closed in presetting bit set in each period System is monitoring information.

Specifically, controller when obtaining the presetting bit set in each period, can also correspond to and determine each target pair As reference scene element corresponding in each presetting bit, which can be understood as minimum with target object distance Situation elements, situation elements refer to position relatively fixed constant object, such as sofa, desk, the TV in parlor etc..

It determines in each concrete mode for being predisposed to upper corresponding reference scene element:

The corresponding monitored picture of the presetting bit is analyzed, determines the position of target object, then determine distance objective pair As the situation elements of surrounding are at a distance from the target object, the central pixel point of situation elements can be used at a distance from target object The distance between central pixel point of target object characterizes, if some situation elements is nearest with a distance from target object, Then the situation elements are reference scene element.

As one embodiment, it is understood that there may be have being equidistant for multiple situation elements and target object, can choose more The highest situation elements of characteristics of image discrimination are as reference scene element in a situation elements.Characteristics of image discrimination is up to Refer to that the characteristics of image of the situation elements is easiest to accurately be identified by controller, the high situation of characteristics of image discrimination includes The shape rule of clear-cut, situation elements the clean marks of the situation elements, the color uniqueness of situation elements and situation elements One or more of then.

After obtaining the corresponding reference scene element of each presetting bit, controller is by target object, target object every The corresponding ginseng of the presetting bit set and target object of a period each presetting bit in the presetting bit set of each period It examines situation elements three to be associated and store, to generate monitoring information.That is, the monitoring in the embodiment of the present application is believed In breath include at least target object, target object each period presetting bit set and target object in each time The corresponding reference scene element of each presetting bit in the presetting bit set of section.

It as one embodiment, can further include target pair in monitoring information in the two ways for generating monitoring information As the search target object success rate of presetting bit each in the presetting bit set of each period.

Specifically, obtaining each target object after the presetting bit set in each period, the first camera shooting of control Search target object of the machine 12 within the corresponding period in presetting bit set in each presetting bit determines every in presetting bit set The successful number of target object is searched in a presetting bit, determines the search target object in presetting bit set in each presetting bit Success rate.It is different to search for total degree, corresponding search target object success rate is different in corresponding each presetting bit, therefore, each Corresponding search target object success rate can be real-time update in presetting bit.

For example, referring to figure 5., the first video camera 12 is located at A point, in the circle that the first video camera 12 can be shown in Fig. 5 Rotation, the presetting bit of preset first video camera 12 is location point shown in a-j in Fig. 5, that is to say, that only the first video camera 12 to when location point, just stopping the corresponding time shown in a-j, is monitored to the corresponding monitored picture in the pre- position.Control Device processed analysis target object appears in kitchen and parlor in first time period 7-10 point, and corresponding presetting bit is a, b, and controller can be with Determine that presetting bit collection of the target object in first time period is combined into { a, b }.

When presetting bit b in Fig. 5, the corresponding target object of the first video camera 12 is appeared in parlor, the first video camera After the 12 obtained monitored pictures of shooting are as shown in fig. 6, controller determines the position of target object, determine that the presetting bit is corresponding The distance of 61 distance objective object of mural painting is L1 in monitored picture, and the distance of 62 distance objective object of desk is L2, and controller is true L1 is determined less than L2, and mural painting 61 is then mural painting 61 as the corresponding reference scene element of presetting bit b by controller.

Controller scans for presetting bit a and b, and controller searches for n times, searches target object on presetting bit a Number is m, and the number that target object is searched on presetting bit b is l, and the search target object success rate on presetting bit a is m/N, Search target object success rate on presetting bit b is l/N.

By the corresponding target object of each controller, target object presetting bit set during this period of time, each preset The reference scene element of position and the search target object success rate associated storage in each presetting bit, generate the target object Monitoring information.

After controller generates monitoring information, step 205 is executed, i.e. reception target following instruction.

Specifically, then need to carry out tracing and monitoring to target object when user needs to be monitored some target object, Target following instruction can be sent to the first video camera 12 by terminal device 11, the software in terminal device 11 can also be passed through Target following instruction is sent using to the first video camera 12.Target following instruction, which is used to indicate, carries out tracking prison to target object Control.In order to save traffic overhead, the corresponding unique identification of target object can be carried in target following instruction, which can With referring to the content discussed in step 303 above, details are not described herein again.

Controller executes step 306 and obtains that is, according to the monitoring information learnt in advance after receiving target following instruction Target object is obtained in the corresponding first presetting bit set of first time period.

Specifically, the target object that user needs to monitor is determined, due to monitoring after controller receives target following instruction It include the monitoring information of multiple target objects in information, therefore, controller needs true according to the monitoring information obtained in step 204 First presetting bit set of the target object in the first time period belonging to current time is made, the first presetting bit set includes All presetting bits that the target object occurred in first time period.

Controller after step 306 is performed, executes step 307, that is, controlling the first video camera 12, to be switched to first preset The corresponding prison of presetting bit in the set of position in each presetting bit, and after being switched to corresponding presetting bit every time, after search switching Whether there is target object in control picture.

Specifically, controller controls each presetting bit switching of first video camera 12 in the first presetting bit set, switching Sequence there are many mode, illustrated below.

Transfer sequence one:

The sequence of plain target object success rate from high to low is searched according to each presetting bit in the first presetting bit set, successively Switch each presetting bit.

Specifically, after obtaining the first presetting bit set, it can be according to the search target of presetting bit each in monitoring information Object success rate arranges each presetting bit in the first presetting bit set according to the sequence of search target object success rate from high to low Column, thus the first presetting bit set after being arranged.Controller is preset to switch according to the first presetting bit set after sequence Position.

In the embodiment of the present application, it is first switched to the search highest presetting bit of target object success rate, it can be with most fast speed Degree finds the presetting bit including target object.

Transfer sequence two:

The distance of presetting bit is currently located according to the first video camera of distance 12 of each presetting bit in the first presetting bit set Sequence from big to small successively switches each presetting bit.

Specifically, controller determines which presetting bit is currently located preset with the first video camera 12 in the first presetting bit set The distance of position is minimum, and controller controls the first video camera 12 and first turns to the position, to reduce the first rotation every time of video camera 12 Angle, reduce the first video camera 12 power consumption.

After switching presetting bit every time, monitored picture of the controller to the corresponding video camera of presetting bit after this time switching It scans for, whether search in the monitored picture has target object.There are many modes of search, is illustrated below.

Way of search one:

The corresponding characteristics of image of target object is obtained, the image of characteristics of image and the target object in monitored picture is special Sign is matched, if the Image Feature Matching of the characteristics of image in some region in monitored picture and target object, really There is the target object in the fixed monitored picture.

Wherein, characteristics of image includes but is not limited to image outline, image texture, image grayscale and color of image etc..

Way of search two:

Utilize sample image, training neural network model；

By monitored picture input value neural network model, input in the monitored picture whether include target object result.

Specifically, controller obtains great amount of samples image, with the neural network model of sample image training building, the nerve Whether network model judges the monitored picture judged will be needed to be input to nerve including target object in some image for determining In network model, thus obtain in the monitored picture whether include target object judging result.

Way of search three:

Corresponding first reference scene element in the corresponding monitored picture of presetting bit after search switching, according to preset matching Window traverses the monitored picture using the first reference scene element as starting point, determines in monitored picture whether there is target object.

Specifically, controller first searches out the first reference scene element from monitored picture, due to the first reference scene member The position and characteristics of image of element are all relatively fixed, therefore controller can promptly match first prestored from monitored picture Reference scene element is traversal starting point with the first reference scene element, determines in monitored picture whether there is target object.Due to Target object distance the first reference scene element is nearest, therefore is traversal starting point with the first reference scene element, can look for as early as possible To target object.

It as one embodiment,, can be with the head of target object when target object is personage in three kinds of ways of search Color is sent out as characteristic matching region, since the hair color of personage is relatively-stationary within a certain period of time, and hair is opposite It more concentrates, therefore the hair color of target object can be used as characteristic matching region, it can first sought from monitored picture The corresponding hair zones of target object are found, rapidly match target object to realize.
