Fig. 2 is the schematic diagram for the polyphaser array that the embodiment of the present invention one provides.Polyphaser battle array described in the present embodiment Column refer to multifocal away from camera array, i.e., to be made of the focal length camera of a wide angle camera and multiple stationary arrangements polyphaser battle array Column, wherein wide angle camera refers to that focal length is shorter, the biggish camera in visual angle, the shooting area bat that is wider, but taking of covering Take the photograph that scenery in picture is relatively small, resolution ratio is relatively low;Focal length camera refers to that focal length is longer, the lesser camera in visual angle, The shooting area of covering is smaller, has higher resolution ratio for the shooting picture of a small range scenery.As shown in Fig. 2, multiphase It include a wide angle camera 100 in machine array, i.e., region-wide camera, position coordinates are denoted as C (0,0), and are arranged in three rows six Be distributed in the focal length camera 101 (1 is only indicated in Fig. 2) of 100 two sides of wide angle camera, i.e., the corresponding camera of each shooting area, The position coordinates of these wide angle cameras are denoted as C (1,1) to C (3,6) respectively.
Fig. 3 is the schematic diagram for the polyphaser array shooting area that the embodiment of the present invention one provides.As shown in figure 3, wide-angle phase Machine 100 covers shooting area (the overstriking black surround in such as Fig. 3 of whole focal length cameras for region-wide shooting, coverage It is shown), this coverage is interior to have multiple shooting areas, and in the distribution that three rows six arrange, each shooting area corresponds respectively to one A focal length camera, and the shooting area of the focal length camera of arranged adjacent has and partially overlaps (such as the part institute that square is overlapped in Fig. 3 Show), the area of intersection can determine in the deployment of polyphaser array and calibration process according to actual needs.
It should be noted that the present embodiment to the determination of target area, to target area alternately target detection and right The target detection of nontarget area is described in detail, and (more) target recognition and tracking algorithm is not construed as limiting, and And polyphaser array deployment when have already passed through visual angle, in terms of calibration.
With reference to Fig. 1, which specifically comprises the following steps:
S110, determined according to the picture of two or more shooting areas corresponding shooting area be target area or Nontarget area, the target area are the regions that object to be detected is likely to occur.
Specifically, it is first determined each shooting area is target area or nontarget area.Polyphaser array is covered Image in whole region is divided into two classes, and target area refers to region (such as road, square for being possible to occur object to be detected Deng), nontarget area refers to the region (such as woods, sky) that object to be detected can not occur, usual for target area It needs to carry out high-precision real-time monitoring, and operation can be used cost is relatively low algorithm for nontarget area (such as background difference is calculated Method) it is monitored.Object to be detected can be pedestrian, vehicle, traffic mark etc., by each shooting area (three rows as shown in Figure 3 Six column and with intersection each square representated by region) picture sequentially input to Target Recognition Algorithms to carry out image Detection and classification, determine whether it is the target area for being likely to occur object to be detected.
Whether S120, shooting area is are target area, if so, thening follow the steps S130;If not, thening follow the steps S140。
Specifically, step S110 has successively determined whether all shooting areas are target area, for different regions, adopt Target detection is carried out with different camera or algorithm, if it is target area, thens follow the steps S130;If it is not, then executing step Rapid S140.
S130, pass through the corresponding camera of the shooting area and region-wide camera alternately target detection, the shooting The high resolution of the corresponding camera in region is in the resolution ratio of the region-wide camera.
Specifically, for target area, when there is object to be detected, need accurately and rapidly detection and tracking it is to be checked Object is surveyed, the detailed information of shooting picture is captured.This implementation is illustratively set for target area, and default setting is utilization pair The camera answered carries out target detection, to provide clearer shooting picture;For nontarget area, default setting is to utilize the whole district Domain camera carries out target detection, to reduce testing cost.With the movement of object to be detected, entered according to object to be detected or from The direction for opening current goal region, can detect which shooting area object to be detected will be transferred to, thus to target area into Row prediction and update, guarantee to track object to be detected in time.On this basis, corresponding using shooting area to target area Camera and region-wide camera alternately target detection.Illustratively, when the shooting area for being originally used for nontarget area becomes When target area, the corresponding camera in the target area is switched to by region-wide camera and carries out target detection;For target area, such as Fruit its shoot resolution requirement it is not high when, be switched to region-wide camera and carry out target detection, such as object outline to be detected is clear And background is more single, and a vehicle is monitored such as on intermountain highway, then for the target area where vehicle, can be switched to complete Area camera carries out target detection;And when needing to obtain the details of vehicle, such as to check license plate, differentiate vehicle model, When recognizing car owner, the corresponding camera in target area where being switched to the vehicle carries out target detection, to provide higher resolution Rate and detection accuracy.
S140, target detection is carried out by the region-wide camera.
Specifically, carry out target detection by region-wide camera if shooting area is nontarget area, with provide compared with Whole shooting picture in wide coverage avoids the splicing and calibration of the image of multiple shooting areas;Simultaneously using fortune Whether the lower algorithm of calculation amount (background difference algorithm) monitoring there is object to be detected in nontarget area, if there is to be detected Object then updates target area, and using the corresponding camera of shooting area and region-wide camera according to actual needs to target area Domain alternately target detection.
It should be noted that the shooting area has multiple, it is corresponding that each shooting area both corresponds to shooting area Camera (focal length camera), the high resolution of the corresponding camera of the shooting area is in the resolution ratio of region-wide camera.It is region-wide The coverage of camera covers the shooting area of the corresponding camera of whole shooting areas, do not need in shooting process calibration or Stitching image can obtain global information, without carrying out image procossing to a large amount of shooting picture, can reduce operand;And The corresponding camera of shooting area can provide the details of more shooting pictures if necessary, and it is careful to carry out to more image pixels Calculation process, to improve the precision of detection and tracking object to be detected.Therefore, the object detection method of the present embodiment passes through more Camera array is respectively adopted different camera to target area and nontarget area and carries out target detection, can take into account detection accuracy with Testing cost.
A kind of object detection method that the embodiment of the present invention one provides, according to the picture of two or more shooting areas Determine that corresponding shooting area is target area or nontarget area;If shooting area is target area, by described The corresponding camera of shooting area and region-wide camera alternately target detection;If shooting area is nontarget area, lead to It crosses the region-wide camera and carries out target detection.Through the above technical solutions, using two different camera roots to target area According to actual demand alternately target detection, operand lower region-wide phase simple using image procossing to nontarget area Machine and algorithm of target detection are monitored, and comprehensively consider testing cost and detection accuracy, are realized flexible using polyphaser array It treats test object and carries out detection and tracking in ground.
Embodiment two
Fig. 4 is a kind of flow chart of object detection method provided by Embodiment 2 of the present invention, and the present embodiment is in above-mentioned reality On the basis of applying example, specifically optimized, determination and update to target area and nontarget area, the corresponding phase of shooting area The alternately target detection of machine and region-wide camera is illustrated, and the technical detail of detailed description can not join in the present embodiment See above-mentioned any embodiment.
Specifically, this method specifically comprises the following steps: with reference to Fig. 4
S210, using center shooting area as current region, using the picture of the center shooting area as current region Picture input Target Recognition Algorithms, the center shooting area is to be located at center in described two or more than two shooting areas The shooting area of position.
Specifically, the startup stage initial in polyphaser array, if using the picture of each shooting area as target area Domain, and whole shooting pictures is input to algorithm of target detection, it can cause greatly to calculate to image procossing and target detection Burden, substantially reduces detection efficiency, and if the shooting picture of region-wide camera is only input to algorithm of target detection, due to dividing The limitation of resolution, may result in can not clearly monitor object to be detected.Starting of the present embodiment in polyphaser array Stage successively activates the corresponding camera of each shooting area according to certain rule, the corresponding camera of each shooting area is monitored Picture is input to algorithm of target detection successively in a certain order to judge whether each shooting area is target area, can be quick It determines target area, improves detection efficiency.
Specifically, whether the center shooting area of first determining whether is target area, the center shooting area refers to multiple It is located at the shooting area of center in shooting area.Fig. 5 A is shooting area current region provided by Embodiment 2 of the present invention Schematic diagram.With reference to Fig. 5 A, the present embodiment illustratively uses 1 region-wide camera and the corresponding camera of 18 shooting areas, entirely The coverage of area camera covers the shooting area of the corresponding camera of all shooting areas, and 18 shooting areas can be divided into three Six column of row, each shooting area correspond respectively to the corresponding camera of 1 shooting area.By 18 shooting area geometry equal part (etc. It is divided into left and right two parts), each equal subregions are in the shooting area of center, i.e. C (2,2) and the corresponding shooting of C (2,5) Region (in Fig. 5 A shown in shade) is used as current region, and the picture of current region is inputted Target Recognition Algorithms, current to determine Whether region is target area.
Whether S220, current region are target area, if so, thening follow the steps S230;If not, thening follow the steps S240。
S230, target identification is inputted using the picture of the adjacent shooting area of the current region as the picture of new current region Algorithm.
Specifically, if current region is target area, continue using the picture of the adjacent shooting area of current region as Whether the picture of new current region inputs Target Recognition Algorithms, be target area with the adjacent shooting area of determination.
Fig. 5 B is the schematic diagram of the adjacent shooting area of current region provided by Embodiment 2 of the present invention.It is calculated according to target following The direction that object to be detected enters and leaves current region (target area) can be obtained in method, thus by that this side up, adjacent The picture of shooting area (in Fig. 5 B shown in shade) inputs Target Recognition Algorithms.It should be noted that the present embodiment is illustratively Adjacent shooting area is limited to the shooting area on the horizontal or vertical direction of current region, since current region is target area Domain, so the probability that object to be detected occurs in shooting area adjacent on horizontal or vertical direction is bigger, be conducive to quickly positioning to Test object.
S240, mesh is inputted using the picture of the shooting area on the current region diagonal line as the picture of new current region Mark recognizer.
Specifically, if current region is nontarget area, by the picture of the shooting area on current region diagonal line Target Recognition Algorithms are inputted, to determine whether the shooting area on diagonal line is target area.
Fig. 5 C is the schematic diagram of the shooting area on current region diagonal line provided by Embodiment 2 of the present invention.If current Region is the nontarget area for being not in object to be detected, then by its diagonally adjacent shooting area (shade in Fig. 5 C It is shown) picture input Target Recognition Algorithms.It should be noted that current region is not in object to be detected, then it is horizontal Or on vertical direction adjacent shooting area occur object to be detected probability it is relatively small, at this time first to the shooting on diagonal line Region is judged, search radius can be expanded, conducive to the target area that object to be detected is likely to occur quickly is positioned.
S250, whether have determined that whole shooting areas are target area or nontarget area, if so, thening follow the steps S260;If not, thening follow the steps S220.
Further, using the shooting area on adjacent shooting area or diagonal line as new current region, judge After whether new current region is target area, continues to expand search range, continued to select new shooting area with same method Judged, until all shooting areas are all targeted region or nontarget area.If it is determined that all shootings Region is target area or nontarget area, thens follow the steps S260, carries out mesh to target area and nontarget area respectively Mark detection, if having not determined whole shooting areas, repeats step S220-S250, judges new current region.
S260, target area alternately target is examined by the corresponding camera of the shooting area and region-wide camera It surveys, target detection is carried out to nontarget area by the region-wide camera.
Specifically, then passing through shooting area if it is determined that whole shooting area is target area or nontarget area Corresponding camera and region-wide camera carry out alternately target detection to target area, by region-wide camera to non-target area Domain carries out target detection.
Further, by the corresponding camera of the shooting area and region-wide camera to target area alternately target Detection, comprising:
By the monitoring confidence level difference and Bhattacharyya system of the corresponding camera of the shooting area and region-wide camera Number fusion, obtains fusion value;
If the fusion value is less than or equal to preset threshold, mesh is carried out to the shooting area by the region-wide camera Mark detection;
If the fusion value be greater than preset threshold, by the corresponding camera of the shooting area to the shooting area into Row target detection.
Specifically, two kinds of switchings between camera are related to for the target detection of target area and nontarget area, Include: when the picture of region-wide camera being input to Target Recognition Algorithms still guaranteeing the precision of target detection and tracking enough, It is shot being switched to the shooting of target area using region-wide camera, or when target area becomes nontarget area, switching To be shot using region-wide camera;When shooting purpose changes, needs analysis or magnified picture details, requires higher shooting When resolution ratio, target detection is carried out by the corresponding camera of the shooting area where is switched to the shooting of nontarget area.
Specifically, needing to assess when to entire area for being switched to the case where carrying out target detection using region-wide camera When the low resolution picture that camera takes is handled, whether algorithm of target detection is capable of providing enough detection and tracking essences Degree, if enough detection and tracking precision can be provided, will be transferred to region-wide camera to the shooting of target area, by the whole district Domain camera is detected and is tracked to the shooting picture input Target Recognition Algorithms of this target area.For example, to intermountain public affairs Vehicle in road carries out detection and tracking, and the clear-cut and background of object to be detected is more single, utilizes region-wide phase at this time The low resolution picture that machine takes also guarantees the position of accurate detection and tracking vehicle enough, at this point for vehicle institute Target area, can be switched to and carry out target detection using region-wide camera, obtained without using the corresponding camera of shooting area To high-resolution shooting picture and splicing and the picture for calibrating each shooting area.Specific appraisal procedure is combined to two types The camera view of type carries out the difference of the confidence level of target detection and the heterochromia of Bhattacharyya coefficient description.
Specifically, the histogram of the corresponding camera shooting picture of shooting area is denoted as p, the histogram of region-wide camera shooting picture Seal is q, it is assumed that two histograms are m grades, then Bhattacharyya coefficient D (p, q) is Remember and the confidence level of target detection and the shooting picture to the corresponding camera of shooting area are carried out to the shooting picture of region-wide camera The difference for carrying out the confidence level of target detection is Dconfidence, then appraisal procedure is embodied as:
If meeting: α D (p, q)+β Dconfidence≤Thandover, then region-wide phase will be transferred to the shooting of this target area Machine;If being unsatisfactory for: α D (p, q)+β Dconfidence≤Thandover, then shooting area pair will be transferred to the shooting of this target area The camera answered.Wherein, confidence level refers to that Target Recognition Algorithms detect the confidence level of object to be detected from shooting picture, and α and β are The weight rule of thumb set, α D (p, q)+β DconfidenceValue is merged for confidence level difference and Bhattacharyya coefficient, ThandoverFor the preset threshold set according to experience, α, β, ThandoverIt can set according to actual needs.
It is further, described by the corresponding camera of the shooting area and region-wide camera alternately target detection, Further include:
The region-wide camera is obtained to the shooting resolution ratio of the object to be detected;
When the shooting resolution ratio is more than or equal to default resolution ratio, then by the region-wide camera to the shooting area Domain carries out target detection;
When the shooting resolution ratio is less than default resolution ratio, then by the corresponding camera of the shooting area to the bat It takes the photograph region and carries out target detection.
Specifically, where being switched to region-wide camera for nontarget area the case where shooting area corresponding camera, Usually for the shooting higher shooting task of resolution requirement, such as not only need to monitor vehicle also and to detect license plate, not only It monitors pedestrian also and to carry out Face datection etc. and cut behind the target area where region-wide camera monitors object to be detected It gives the corresponding camera in the target area and carries out target detection.
Illustratively, it can default and first pass through region-wide camera the object to be detected is shot, obtain region-wide phase The shooting resolution ratio of machine, or shooting resolution ratio is calculated according to the performance parameter of region-wide camera, and by itself and default resolution ratio It is compared, default resolution ratio can be set according to the actual demand of different task.For example, region-wide camera is to described to be detected right The shooting resolution ratio of elephant is 960P, and for vehicle tracking task, presetting resolution ratio is 960P, then region-wide camera can meet need It asks, vehicle tracking is carried out to target area by region-wide camera;But for car plate detection task, default resolution ratio is 1080P then needs to switch to the corresponding camera of shooting area and carries out target detection to the target area.It should be noted that Shooting resolution ratio and default resolution ratio can also be expressed as form, such as super clear, high definition of grade etc..
Further, if being nontarget area in the shooting area, target is carried out by the region-wide camera After detection, further includes:
The shooting picture of the region-wide camera is monitored using background difference algorithm;
If detecting object to be detected in the shooting picture, again according to the picture of two or more shooting areas Face determines that corresponding shooting area is target area or nontarget area.
Specifically, carrying out target detection using region-wide camera, and lower-cost using calculating for nontarget area Background difference algorithm is monitored the picture of region-wide shooting line machine, wherein background difference algorithm is to introduce normal distribution Background difference algorithm, is embodied as:
Wherein, μt=ρ It+(1-ρ)μt-1,D=| (Itt) |, k is empirical value, can basis Actual demand setting, the present embodiment set k=2.5, and initial value when t=0 isμ0、σ0It is set according to experience Value, ItFor the intensity of the pixel of t moment, μt、σtFor the parameter of normal distribution.It can determine whether the t moment pixel according to above-mentioned formula Point is prospect (foreground) or background (background), with detect in nontarget area whether occur it is to be detected right As.
Further, after determining that whole shooting areas are target area or nontarget area, to target area and Constantly update the accuracy to guarantee algorithm of target detection in nontarget area.For the picture that a certain moment takes, if intensity Meet for the pixel p (x, y) of I (x, y):
Then judge that pixel p (x, y) belongs to target area, if not satisfied, then pixel p (x, y) belong to it is non-targeted Region, wherein rneighborFor empirical value, expression be may determine that as the neighborhood distance of same object to be detected, with object to be detected Size be positively correlated, for example, object to be detected be vehicle, rneighborBe 20, indicate exist can be used as differentiate radius, less than 20 R, to differentiate the pixel whether be object to be detected target area;Object to be detected is behaved, rneighborIt is 10, indicates Differentiate radius, r less than 10 in the presence of can be used as, to judge the pixel whether be object to be detected target area, PtargetIndicate the set of the pixel of the target area of object to be detected.
Further, when object to be detected enter the shooting area visual angle overlapping region when, by script to it is described to The corresponding camera of shooting area that test object carries out target detection provides the probability distribution of the object's position to be detected;
According to the probability distribution by the object to be detected possibly into shooting area be ranked up from high to low;
According to ranking results successively by it is described possibly into shooting area be input to Target Recognition Algorithms, until determine institute State the shooting area that object to be detected enters.
