According to the invention, the position and the size of the sticker are recalculated, and the sticker and the photographing data are synthesized after recalculation, so that the picture of the sticker is finally generated. The resolution ratio of the map photographing is greatly improved, and the image quality is improved.
Description
Technical Field
The invention belongs to the technical field of terminal photographing, and particularly relates to a method for improving the resolution of mapping photographing.
Background
And (3) mapping photographing, wherein during photographing, a favorite mapping is selected and placed in a preview frame of a camera, and after the photographing is clicked, the preview data is used for combining the photo and the mapping into a photo, so that the playability and the interestingness of photographing are improved. In the prior art, the mapping photographing uses preview data, and a camera has two paths of data, namely preview data and photographing data. The preview data has low resolution, which is basically only 1080p or 720p, but the resolution of the camera is much higher than the resolution, and the maximum size supported by the camera can be reached, so the resolution of the picture shot by the current map shooting is low, and the picture quality is low.
Therefore, a method for improving the resolution of mapping photographing is needed, so that the resolution of the photographed picture can be improved in the mapping photographing scene, and the picture quality can be improved.
Disclosure of Invention
In view of the above-mentioned deficiencies of the prior art, it is an object of the present invention to address the above-mentioned problems of the prior art.
In order to achieve the above object, the present invention provides a method for improving a resolution of a mapping photo, which is used for a terminal having a mapping photo function, and the method includes:
entering a camera APP of the terminal, selecting a mapping to be pasted in a pre-shot picture, and recording a mapping position pos;
clicking a photographing button, setting photographing data by a photographing device, reading photographing resolution and preview resolution, and calculating the width-height difference ratio of the two resolutions;
respectively putting the picture data and the map data into corresponding bitmap, calculating the position and the size pos' of the map in the camera data, and carrying out Scale scaling operation on the map data according to new parameters;
and synthesizing the two bitmaps according to the parameters to generate a map photo.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a method for improving mapping photographing resolution, which is used for a terminal with a mapping photographing function, and comprises the following steps: entering a camera APP of a terminal, previewing photographing settings to be photographing data, selecting a mapping to be pasted in a pre-photographing picture, and recording a mapping position pos; clicking a photographing button, reading photographing resolution and preview resolution, and calculating the width-height difference ratio of the two resolutions; respectively putting the picture data and the map data into corresponding bitmap, calculating the position and the size pos' of the map in the camera data, and carrying out Scale scaling operation on the map data according to new parameters; and synthesizing the two bitmaps according to the parameters to generate a map photo. According to the invention, the position and the size of the sticker are recalculated, and the sticker and the photographing data are synthesized after recalculation, so that the picture of the sticker is finally generated. The resolution ratio of the map photographing is greatly improved, and the image quality is improved.
Drawings
FIG. 1 is a schematic block diagram of a process of the method for improving the resolution of a picture taken by a map according to the present invention.
Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the method for improving the resolution of mapping and photographing provided by the present invention is used for a terminal with a mapping and photographing function, and the method includes the following steps:
s10, entering a camera APP of the terminal, selecting a map to be pasted in the pre-shot picture, and recording the position pos (x, y, wide, right) of the map;
it should be noted that there are two paths of data for taking a picture, one path is preview data, and the other path is shooting data; the preview data is a preview interface after the camera APP is opened, the preview data is convenient for a user to preview and observe scenes, the resolution of the preview data is generally low and basically only has the resolution of 1080p or 720p, but the resolution of the camera is much larger than the resolution, and the maximum size supported by the camera can be achieved; the photographing data is based on the size of the camera, and the resolution can be very large basically, for example, a camera with the size of 13m can photograph a picture with the size of 4K;
the function of the photo sticker is to select some icons, such as addresses, moods and the like, during photo taking, directly attach the icons to the preview of the photo, and then combine the preview data and the sticker data when clicking to take the photo to produce a photo.
S20, clicking a photographing button, taking photographing data by the photographing device, reading photographing resolution and preview resolution, and calculating the width-height difference ratio of the two resolutions;
it should be noted that the format of the resolution is (wide, high) format, and the ratio of the width to height difference between the two respective ratios (photographing resolution wide/preview resolution wide, photographing resolution high/preview resolution high) is calculated as (x ', y').
S30, respectively putting the picture data and the map data into corresponding bitmap, calculating the position and size pos' of the map in the camera data, and carrying out Scale scaling operation on the map data according to new parameters;
it should be noted that the calculation of the position and size pos' of the map in the camera data is performed by using the following formula:
pos'＝(x*x'，y*y'，wide*x',hight*y')
the new parameter, pos, is the calculated position of the sticker composition.
And S40, synthesizing the two bitmaps according to the parameters to generate a map photo.
It should be noted that, after the camera data is used, the resolution is increased, the position of the map in the preview needs to be recalculated, and the size of the bitmap needs to be scaled, otherwise, the bitmap size does not match the scale, so in step S30, the calculation needs to be performed again according to the size ratio of the preview data to the photographed data.
According to the invention, the position and the size of the sticker are recalculated, and the sticker and the photographing data are synthesized after recalculation, so that the picture of the sticker is finally generated. The resolution ratio of the map photographing is greatly improved, and the image quality is improved.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
