Fig. 1 shows the realization flow of the image-selecting method that first embodiment of the invention provides, and to this, details are as follows:
In step S101, obtain the depth information waiting to select each pixel in image.
Concrete, described in wait to select image, the i.e. objective for implementation of image-selecting method described in the embodiment of the present invention.The embodiment of the present invention needs in the information waiting to select to select in image required for certain customers.Information required for described user can be main information, the personage etc. in such as image.Certainly, the information required for described note also can be background information, such as extracts the background information etc. of a landscape picture.
Described waiting selects the pixel in image, with to wait to select the resolution of image relevant.For the image of two same sizes, higher when waiting to select the resolution of image, then this waits to select image to need the number of the pixel of compute depth also more.
The depth information of described image, namely in scene, each pixel of object is relative to the distance of imaging terminal, and described object can by light imaging in shooting camera to reflection for people, tree, automobile, house etc., observable object.The depth information of described image, can be obtained by the method for the depth information of current various computed image, the depth information of each point in object such as can be obtained by laser radar range, also can be found range by zoom, or the mode of multi-base stereo imaging, obtains the depth information of each point in image.Certainly, according to the mode of the dual camera range finding described in the embodiment of the present invention two, the depth information of image can also be obtained, specifically will introduce in the embodiment of the present invention two.
In step s 102, receive the depth information of user's input, in described image, search the pixel corresponding with the depth information that described user inputs.
Concrete, the depth information of described user's input, can be obtained by the mode of recording user alternative in the picture.Such as user can point out the position of required image by the mode touched, such as user touches portrait position in image, depth information that then can be corresponding according to the location lookup of touch point, and search the pixel corresponding with this depth information in the picture.
Certainly, the depth information of described user's input, also can be directly input a depth value, such as depth information be a distance value of 5m, thus directly searches corresponding pixel according to the distance value of this input.
The corresponding relation of described depth information and pixel, can for a depth information ranges centered by the depth information of input, also can be a region on border for the depth information inputted, such as can for being less than all pixels of the depth information of input, or be greater than all pixels of depth information of input.Certainly, should not be confined to these concrete execution modes that the embodiment of the present invention exemplifies, according to concrete selection requirement, can select the relation of different correspondences flexibly, specifically have in the embodiment of the present invention three and introduce explanation accordingly.
In step s 103, the image selected zone corresponding to depth information of described user input is formed according to the pixel searched.
Concrete, the described pixel searched, refers to the search criterion met described in step S102, the set of pixel corresponding with the depth information that user inputs in other words, the described pixel met the demands is selected by tool, can obtain in the described selection waiting the object selecting image.
Described selected zone, can be chosen by highlighted dotted line frame, and other mark obviously can distinguishing current selected areas also can be used to mark, or is carried out by unchecked image hiding display.To facilitate user to watch current selection mode information in time, and adjust correction timely according to current selection mode information.
The depth information of user's input that the embodiment of the present invention receives, and search corresponding pixel in the picture according to the depth information receiving user's input, the required region selected is determined according to the pixel searched, can select by depth information the image-region that the depth information of input is corresponding fast and effectively, thus simple to operate, that choice accuracy is high goal of the invention can be realized.
Embodiment two:
Fig. 2 shows the realization flow of the image-selecting method that second embodiment of the invention provides, and details are as follows:
In step s 201, the first image and the second image is obtained according to dual camera.
Concrete, described dual camera can be the camera of two center line equalitys, and the distance of two cameras presets.Described camera can be simulation camera, also can be digital camera, for ease of the comparison of the image that two cameras obtain, generally select the camera of same kind, so that follow-up comparison calculates.
When the resolution of two cameras is different, such as the resolution of the first image is high, then the resolution of the first high for resolution image can be turned down, make the resolution of the first image after adjustment identical with the resolution of the second image.
Include in the first image, but the image do not comprised in the second image, because it directly can not calculate the depth information of its correspondence, then can using this parts of images not as waiting the part selecting image.
In step S202, according to the parallax information of same object and the positional information of dual camera in described first image and the second image, obtain the depth information of pixel in image.
Because the position of two cameras is different, therefore, be similar to the eyes of people, the first image obtained by two cameras and the second image, can determine the parallax information of two images, according to the range information of obtained parallax information and two cameras, near according to distance video camera distance, parallax is large, the principle that during distance video camera distance, parallax is little, by mating the first image and the second image, the depth information of each pixel can be calculated.
In step S203, receive the depth information of user's input, in described image, search the pixel corresponding with the depth information that described user inputs.
In step S204, form the image selected zone corresponding to depth information of described user input according to the pixel searched.
Step S203-S204 is identical with step S102-S103 in the embodiment of the present invention one, does not repeat at this.
The difference of the embodiment of the present invention and embodiment one is, the embodiment of the present invention obtains the first image and the second image respectively by dual camera, and by the coupling of image, complete the calculating of the depth information of image, compare with the obtain manner of other depth information, the cost that the embodiment of the present invention obtains image depth information is lower, and calculates more for convenience, can significantly improve image of the present invention and select the convenient convenience applied in the terminal.
Embodiment three:
Fig. 3 shows the realization flow of the image-selecting method that third embodiment of the invention provides, and details are as follows:
In step S301, obtain the depth information waiting to select each pixel in image.Specifically can be identical with step S101 described in the embodiment of the present invention one.
In step s 302, receive the touch area of user's input, the depth information that the mean depth information calculating the pixel of described touch area inputs as user, or the depth information that the depth information value receiving user's input inputs as user.
Concrete, due to the convenience of the use of touch terminal, touch screen terminal uses also more and more extensive, when user clicks object to be selected by touching, because the pixel of image is generally much smaller than the region touched corresponding to instruction, for Obtaining Accurate touches the depth information corresponding to instruction, can adopt in two ways:
1, by obtaining the touch area touched corresponding to instruction, search the depth information of each pixel in this touch area, and calculate the mean value of the depth information of all pixels in this touch area, by the mean value of this depth information, as the depth information of user's input;
2, search the touch area that touch instruction is corresponding, and calculate the central pixel point of this touch area, calculate the depth information of this central pixel point, as the depth information of user's input.
Certainly, above-mentioned two kinds of modes are the mode of the depth information of wherein preferably two kinds of acquisition users input, are to be understood that and are not limited to above-mentioned two kinds of modes.
The depth information of user's input, directly can also input the mode of depth information value, as by the depth information slider bar of setting, removable slider bar realizes the adjustment of depth information, and the real-time image selected zone can observed corresponding to depth information, thus realize the adjustment of image selected zone more easily.
In step S303, the depth information ranges that the depth information inputted according to described user is determined.
According to user input depth information, multiple corresponding relation can be adopted, to determine the depth information ranges that the depth information that described user inputs is determined, specifically can comprise as:
Centered by the depth information that described user inputs, the degree of depth radius according to setting determines described depth information ranges; Or
The depth information inputted with described user is critical point, to be greater than the depth information of described user input as described depth information ranges; Or
The depth information inputted with described user is critical point, to be less than or equal to the depth information of described user input as described depth information ranges.
Wherein, a kind of typical application scenarios can be such as, comprise multiple objects that the distance of camera distance is different in the picture, then can according to the depth information ranges selected centered by the depth information of input, by the size of percentage regulation range of information, the precision of selected object can be adjusted further.
And for some image subject and background information distance image relatively far apart, then by using the depth information being less than or equal to described user input as described depth information ranges.For avoid required image not can completely choose, can the boundary value of the depth information of main body and background in computed image further, the pixel of the boundary value being less than described depth information is selected, or hides unselected pixel.
Same reason, for the distance image relatively far apart of image subject and background information, when extracting its background image, then can adopt contrary mode, selects the pixel being greater than the critical value of depth information.
In step s 304, according to described depth information ranges, select to search the pixel belonging to described depth information ranges in image described waiting.
In step S305, form the image selected zone corresponding to depth information of described user input according to the pixel searched.
Step S304-S305 is identical with step S102-S103 in the embodiment of the present invention one, does not repeat at this.
The difference of the embodiment of the present invention and embodiment one is, the embodiment of the present invention specifically describes the step obtaining corresponding pixel, the depth information ranges that the depth information inputted by user is corresponding, can make the required pixel selected of acquisition that user can be more convenient.Improve acquisition efficiency and the accuracy rate of pixel, be understandable that, the distinctive points of the embodiment of the present invention and embodiment one, can be applied to equally in embodiment two and obtain corresponding technique effect.

In step S402, receive the depth information of user's input, in described image, search the pixel corresponding with the depth information that described user inputs.Identical with step S102 in embodiment one.
In step S403, judge whether the region that the pixel searched is formed comprises multiple region.
Concrete, whether the multiple regions described in the embodiment of the present invention are that continuum carries out distinguishing according to searched pixel.When in the pixel searched, when one of them partial pixel point searched is not connected with other pixel searching part, then think that the pixel that this searches part is an independent region.
The situation in multiple region is there is in described image, can be understood as and there is multiple self-existent object corresponding to selected depth information in the picture, can be such as the object such as the multiple people being positioned at same depth bounds existed in the picture or multiple actions, certainly also may comprise other foreign material information.
In step s 404, if the region that the pixel searched is formed comprises multiple region, then receive the confirmation instruction in one or more region of selection of user's input.
When there is the region that multiple pixel searched is formed in image, for avoiding occurring falsely dropping the situation of selecting, the confirmation instruction of user's input can be received, confirming the required region selected.And other unacknowledged region, then not can think it is the required region selected of user, can selection mode be cancelled.
Certainly, as the execution mode that the embodiment of the present invention is optimized further, method described in the embodiment of the present invention can also comprise step S405, in step S405, by the selected zone of described image and other image co-registration.
