The embodiment of the present invention is binocular vision target following to be realized based on natural light, therefore all are close with natural optical wavelength Light source be likely to cause interference, thus using Anti-interference algorithm handle.
Target object reflects natural light, and camera can be by its image capture.Object has its characteristic feature, such as width, height Degree, brightness, like circularity etc..In general, needing through some target object of multiple features ability accurate descriptions.The embodiment of the present invention The Anti-interference algorithm of use is exactly based on series of features to identify targets of interest, filters out non-targeted object.In the specific implementation, Width, height, the control of area equidimension information are fairly simple.The control of luminance information is mainly used to filter light source interference, real Processing first is carried out to image now and obtains grayscale image, reduces data processing load, to higher or lower than certain gray scale (threshold value) Goal-setting " filters out label ".Refer to that target two-dimensional projection tends to circular degree like circularity, mesh is found out by algorithm in realization Lower limit and the upper limit is arranged like circularity in mark, and the object or light like circularity section, outside section for filtering out interference are defined with this " filtering out label " will be set in source, finally decide whether to execute filtering according to label weight, this is the main of Anti-interference algorithm Mentality of designing.Wherein, asking is comparison basis like circularity and mature calculating process, is first found out with function (such as findcontours) Then objective contour seeks the radius of profile minimum circumscribed circle and minimum inscribed circle respectively, two radiuses are closer, illustrate that target is got over Close to circle.
The validity of Anti-interference algorithm is shown below by experiment
Experiment condition: under the conditions of natural lighting, select two common cameras as image capture device, the bead that shines is made To track target.Emphasis detects the stability of Anti-interference algorithm and the stability and real-time of binocular vision track algorithm.
Comparison setting: it compares whether there is or not the detection in the case of Anti-interference algorithm, track situation.
Experimental result: such as Fig. 2, left side is former phase, and centre is the target detection effect without Anti-interference algorithm, and right side is anti-dry Disturb algorithm effect.As it can be seen that the light source for generating interference to target in image has been filtered, and algorithm has traced into the center of target Position (black Labeling Coordinate in former phase).
Concrete methods of realizing are as follows: first extract in image that (for computer, profile just represents object for the profile of each target object Body, while the corresponding number of each profile is to distinguish), and then determine the width of target object, height, like circularity etc.;Figure As being converted into grayscale image, the brightness of target object is determined.Feature according to the characteristic information of above-mentioned target object, with targets of interest It is compared, if similarity degree meets the range of setting, then it is assumed that this target object is targets of interest, on the contrary then delete this A target object.
Therefore step 104 specifically includes:
Closed regions extraction operation is carried out to treated image, each target object in the image that determines that treated.
Obtain the characteristic information of each target object;The characteristic information includes dimension information, like circularity information, bright Spend information;The contour line for specially extracting each target object, determine each target object like circularity information and Dimension information;The dimension information includes height, width and area;Determine the luminance information of each target object.
The characteristic information of each target object is compared with the constraint condition of the targets of interest, determines interest Target.
Camera is demarcated, determines camera parameter.
According to the camera parameter, world coordinate system is established.
According to the world coordinate system and the targets of interest, the coordinate of the targets of interest is determined;The coordinate packet Include two-dimensional coordinate and three-dimensional coordinate.
Step 106 specifically:
One considerable advantage of binocular vision system is exactly the depth information that can obtain object within sweep of the eye, in order to fill Divide and utilized, devises depth of field control algolithm.By this depth of field control algolithm can from sterically control image treatment region between, Object outside depth of field section will not be processed, for there is (such as secret protection of common monitoring system of space protection demand Problem) application scenarios have definite meaning.
Depth information is had in the three-dimensional coordinate of targets of interest, when depth of field control algolithm executes, in the common of two cameras In the visual field, certain row distance is separated by each frame image or column distance acquires several targets of interest points, is obtained through three-dimensional localization process The three-dimensional data of targets of interest point is obtained, wherein including depth information, by this several targets of interest point to drafting based on camera Then the mapping relations of spatial coordinate and two-dimensional coordinate read the depth of field control interval of user preset, closed according to the mapping of drafting System's feedback arrives two dimensional image processing unit, is achieved in the image procossing control to setting depth of field section.
Specific mapping relations are depending on application environment and used equipment, because wherein having used camera calibration Result.So-called " spatial coordinate " is that the coordinate-system based on double camera that camera calibration is established later (is also world coordinates System), the three-dimensional coordinate in world coordinate system, and one are then calculated according to one group of two-dimensional coordinate of the same point of double camera acquisition One is corresponding, and then establishes the mapping relations of two-dimensional coordinate and three-dimensional coordinate.
Step 107 specifically includes:
Section is handled according to described image, the image in described image sequence is divided, determines image sequence to be processed Column, return step 102, and image sequence to be processed is replaced into image sequence, until determining described emerging in image procossing section The three-dimensional coordinate of interesting target terminates.
Fig. 3 is the block diagram of setting regions target tracking system of the embodiment of the present invention based on natural light binocular vision, such as Fig. 3 Shown, the basic device of the setting regions target tracking system is two general cameras.Camera acquires image in the visual field, in image Processing stage carries out the processing such as gray processing, binaryzation, smothing filtering, and Anti-interference algorithm extracts contour of object later, according to default Dimension information, brightness, identify target like features such as circularity and filter non-targeted object, carried out according to features described above in each frame Pixel matching successively keeps the tracking to target.Camera calibration process obtains the inside and outside parameter of system camera, for establishing the world Coordinate system calculated and works as in conjunction with the two dimensional image that tracking process obtains according to the three-dimensional system of coordinate of foundation in the three-dimensional localization stage The three-dimensional coordinate of previous frame target completes positioning.Then it according to depth of field parameter set by user, realizes depth of field control, returns to target Image processing unit, and then realize the target image processing in setting range, complete target location tracking in setting range.
