In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In the embodiment of the present invention, the last photo for taking pictures to obtain is obtained, and the photo of acquisition is handled, is gone
Except the photo of foreground area, only remaining background area, translucent processing is carried out to the photo of the remaining background area, obtained
Translucent background area, the background of the translucent background area being overlapped mutually and current outdoor scene is shown in display window
Region；The angle of camera is adjusted so that the background area of outdoor scene and the semitransparent background region at least partly weight
It is folded.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Embodiment one：
Fig. 1 shows a kind of flow chart for photographic method that first embodiment of the invention provides, in the present embodiment, Yong Hu
The place for having taken photo is taken pictures again, by by the background area of photo compared with the background area of outdoor scene, to determine this
The position taken pictures, details are as follows：
Step S11, obtain the last photo for taking pictures to obtain.
In the step, photo that the last time takes pictures to obtain in current location takes pictures obtained photo before referring to.On if
The photo that once photo taking obtains is stored in the memory of this photographing device, then recalls the photo from memory；It is if last
The photo for taking pictures to obtain is stored in other storage devices, then need to find the photo from other storage devices, and is stored in this
In the memory of secondary photographing device, then from the memory of this photographing device recall the photo.
Step S12, the photo of acquisition is handled, obtain removing the photo of foreground area, only remaining background area.
Due to foreground area can be focused on during shooting photo, therefore more high-frequency signal in foreground area be present, and carry on the back
Scene area can cause picture to be gelatinized because of the limitation of lens aperture, high-frequency signal unobvious, as shown in Figure 2.
In this step, foreground area and background can be distinguished according to the different high-frequency signals of foreground area and background area
Region.
Wherein, when removing foreground area by high-pass filter, the photo of described pair of acquisition is handled, and is removed
The step of photo of foreground area, only remaining background area, specifically includes：
A1, by the photo of acquisition by high pass filter, processes, obtain prospect value and background after high pass filter, processes
Value, for the prospect value to obtain pixel value corresponding to foreground area after high pass filter, processes, the background value is high-pass filtering
Pixel value corresponding to background area is obtained after device processing.
A2, by the prospect value after high pass filter, processes and background value and the prospect value and background before high pass filter, processes
Value compares, and obtains foreground area and the background area of photo.
A3, foreground area is removed, obtain the photo of only remaining background area.
In above-mentioned steps A1~A3, after high pass filter, processes, prospect value will not decay substantially, and background value can decline
Subtract, referring to Fig. 3, in figure 3, the background image of gelatinization is more gelatinized after high-pass filter originally.According to high frequency value (before i.e.
Scape value) it is substantially unattenuated after high-pass filter, low frequency value can decay this rule after high-pass filter, compare high pass
The forward and backward prospect value of filter process and background value, it is background area by the regional determination more than pad value, the area that pad value is lacked
Domain is determined as foreground area, then removes the image in foreground area, obtains the Background of no prospect.
Wherein, when removing foreground area by low pass filter, the photo of described pair of acquisition is handled, and is removed
The step of photo of foreground area, only remaining background area, specifically includes：
B1, the photo of acquisition handled by low pass filter, obtain the prospect value and background after low pass filter processing
Value, the prospect value are to obtain pixel value corresponding to foreground area after low pass filter is handled, and the background value is LPF
Pixel value corresponding to background area is obtained after device processing.
B2, low pass filter is handled after prospect value and background value and low pass filter before processing prospect value and background
Value compares, and obtains foreground area and the background area of photo.
B3, foreground area is removed, obtain the photo of only remaining background area.
In above-mentioned steps B1~B3, after low pass filter is handled, prospect value can decay, and background value will not decline substantially
Subtract, referring to Fig. 4, in Fig. 4, the image of the people of foreground area becomes to be gelatinized after low pass filter.According to high frequency value (before i.e.
Scape value) it can decay after low pass filter, this rule and low frequency value will not decay substantially after low pass filter, compare
The forward and backward prospect value of low pass filter processing and background value, are foreground area by the regional determination more than pad value, and pad value is few
Regional determination be background area, then as shown in Figure 5 remove foreground area in image, obtain the Background of no prospect.
Step S13, translucent processing is carried out to the photo of the remaining background area, obtains translucent background area
Domain, the translucent background area being overlapped mutually and the background area of current outdoor scene are shown in display window.

In region at least in the presence of a polygon size and location it is identical when, judge the background of the semitransparent background region and outdoor scene
Region is least partially overlapped.In the step, choose the semitransparent background region all objects contours segmentation into it is polygon
Any one polygon in shape, such as the triangle in Fig. 7 is chosen, with having the polygon of same shape in the background area of outdoor scene
Shape (i.e. triangle) compares, if two polygons compared is of different sizes, but shape is similar, then auto zoom camera,
Or prompting user scales camera, to compare again, if scaling camera still compares unsuccessful (the object hair of such as background area
Change has been given birth to, such as comparison is same tree, but the proportionate relationship on each bar side of polygon is changed because tree grows tall, therefore compare
To unsuccessful), then the semitransparent background region all objects contours segmentation into polygon in choose another more
Side shape is more until finding a size identical with having the polygon of same shape to be compared in the background area of outdoor scene
Side shape.Further, after a size identical polygon is found, according to the position of the two size identical polygons
Relation, camera or prompting user's dollying head are automatically moved, makes the two polygons overlapping.When above-mentioned two polygon
