Preferred embodiment of the invention

The embodiment of the invention provides a method for photographing a three-dimensional photo of a single camera of a mobile terminal and a mobile terminal. The stereoscopic photo can be viewed through the existing stereoscopic photo technology, so that the mobile terminal also has a stereo photo shooting function, which simplifies the user's shooting and enjoys the stereoscopic image. Photo manipulation. Give users more fun to shoot, and share stereo photos with others via mobile phone. The embodiments of the present invention are described in detail below with reference to the accompanying drawings, and the features of the embodiments and the embodiments of the present invention can be arbitrarily combined with each other without conflict.

Embodiment 1

The embodiment provides a method for photographing a three-dimensional photo based on a mobile terminal. Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for photographing a three-dimensional photo of a mobile terminal, where the method includes:

Step S101: collecting, at the first shooting position, the first perspective image data of a three-dimensional scene by using a camera;

In this step, the user points the camera on the mobile terminal to the three-dimensional scene to be photographed, and the image sensor converts the collected optical signal into an electrical signal (analog signal), and then the processor converts the analog signal into a digital signal to become the first angle of view. The image data of the photo is sent to the display for the user to preview. After the user has previewed, the image data can be saved after being determined to be satisfactory. The specific saving may include encoding the image data of the first view photo into a data format supported by the camera device, and generating an image file, which is temporarily stored in the memory, and the memory may be a built-in memory or a mobile memory. This operation is performed by the user pressing an operation button, such as a shutter or a photo button.

Step S102: horizontally shifting the second photographing position of the specific distance horizontally at the first photographing position, and acquiring second view image data of the three-dimensional scene by the camera;

In this step, the user shifts the mobile phone to the right in the horizontal direction by a specific distance, and the specific distance is specifically moved according to the shooting scene. For example, the specific distance may be 4-6 cm, that is, the left and right eyelid distance is adjusted, and the horizontal distance may be left here. Move, or move horizontally to the right. Of course, the specific distance should specifically be a distance reference for the distance of the three-dimensional scene. For example, if the close-up is taken, the displacement distance needs to be relatively small, and the shooting distance requires a relatively long displacement distance. Of course, the movement process can also be moved in other ways. It should be understood that as long as the shooting position can be horizontally displaced by a certain distance, the image data of the second viewing angle image and the image data of the first viewing angle photo have a certain viewing angle difference. Of course, the specific process can be adjusted by the user to the target of the shooting. Of course, it must be ensured that the image data of the first-view photo is the same three-dimensional scene, that is, the two shots are shots of different angles of the same target. Since the two shots are in different viewing angles, the shooting scene is a static scene.

Step S103: determining first view image data and second view image data as left view image data and right view image data according to corresponding photographing positions;

In this step, if the image data of the first view photo is taken to the right and then moved horizontally, the image data of the first view photo is the left eye view photo data, and the image data of the second view photo is the right eye view photo. Data; if the image data of the first view photo is taken to the left, the image data of the first view photo is the right eye view photo data, and the image data of the second view photo is the left eye view photo data. It should be understood that the real left view image data and the right view image data are determined according to the image data of the first view photo and the image data of the second view photo.

Step S104: synthesizing left view image data and right view image data to generate composite image data;

In this step, it should be understood that the synthesis of the image data can be completed by the basic operations of the other existing software and the mobile terminal itself, and the existing related calculations.

Step S105: Save the composite image data.

The user performs preview based on the composite image data of the stereo photos synthesized in step S104, and if the user's needs are met, the composite image data can be saved in the memory by pressing the enter key. This step occurs after the user determines that the stereoscopic effect of the image on the display is obvious, and presses an operation button to complete, such as a shutter or a photo save button.

Embodiment 2

The embodiment provides a more detailed method for three-dimensional photo shooting of a single camera of a mobile terminal. In this embodiment, the user can perform image capturing of the image data of the second perspective photo according to the image data of the first perspective photo. The accuracy of the shooting makes it easier to better reflect the three-dimensional effect. Referring to FIG. 2a, the method includes the following steps:

Step S201: collecting, at the first shooting position, the first perspective image data of a three-dimensional scene by the camera of the mobile terminal;

Step S202: intercepting specific partial image data of the first perspective image data;

In this step, in order to facilitate the acquisition of the image data of the second perspective photo, that is, the user conveniently performs the photographing of the photo image data of the second viewing angle, the image data of the specific portion of the first viewing angle image data is intercepted. The interception can be intercepted by the user himself, that is, the user himself selects a specific or favorite portion as reference data of the image data of the second perspective photo. It should be understood that the specific portion of the intercepted data can be implemented as long as it can be used as a reference for the user to perform data collection of the second perspective photo. Of course, a button can also be set, and the mobile terminal automatically acquires a specific portion of the image data of the first view photo.

Step S203: Display specific partial image data on the display screen of the mobile terminal;

In this step, after obtaining a specific portion of the image data of the first perspective photo, the user can preview the image first, and after the preview is satisfied, the specific portion of the first perspective photo is displayed on the shooting preview interface for the user to refer to.

Step S204: The second shooting angle data of the three-dimensional scene is acquired by the camera by the second shooting position of the specific shooting distance of the first shooting level;

In this step, the user shifts the mobile phone to the right in the horizontal direction by a specific distance, and the specific distance is specifically moved according to the shooting scene. For example, the specific distance may be 4-6 cm, where the horizontal distance may be moved to the left or horizontally to the right. . Of course, the specific distance should specifically be a distance reference for the distance of the three-dimensional scene. For example, if the close-up is taken, the displacement distance needs to be relatively small, and the shooting distance requires a relatively long displacement distance. Of course, the movement process can also be moved in other ways. It should be understood that as long as the shooting position can be horizontally displaced by a certain distance, the image data of the second viewing angle image and the image data of the first viewing angle photo have a certain viewing angle difference. Of course, the specific process can be adjusted by the user to the target of the shooting. Of course, it must be ensured that the image data of the first-view photo is the same three-dimensional scene, that is, the two shots are shots of different angles of the same target. Since the two shots are in different viewing angles, the shooting scene is a static scene.

Step S205: determining first view image data and second view image data as left view image data and right view image data according to corresponding photographing positions;

In this step, if the image data of the first view photo is taken to the right and then moved horizontally, the image data of the first view photo is the left eye view photo data, and the image data of the second view photo is the right eye view photo. Data; if the image data of the first view photo is taken to the left, the image data of the first view photo is the right eye view photo data, and the image data of the second view photo is the left eye view photo data. It should be understood that the left-view image data and the right-eye view data which are seen by the left eye are determined according to the image data of the first-view photograph and the image data photographing position of the second-view photograph.

Step S206: synthesizing left view image data and right view image data to generate composite image data;

Step S207: Save the composite image data.

The user performs preview based on the composite image data of the stereo photos synthesized in step S206, and if the user's needs are met, the composite image data can be saved in the memory by pressing the enter key. This step occurs after the user determines that the stereoscopic effect of the image on the display is obvious, and presses an operation button to complete, such as a shutter or a photo save button.

In the above step S203, corresponding to the captured partial partial image data, the image data in the in-focus frame of the first view image data, the image data of the four corners, the image data of the four sides, and all the images may be intercepted for the convenience of the user. The data is medium, and it should be understood that the intercepted portion can be realized as long as it can be used for the user to perform image data acquisition reference of the second perspective photo.

In the above step S204, in order to facilitate the user's observation, the image data collection of the second perspective photo is better performed, and even if the specific part of the reference data is more convenient for reference, the content displayed on the screen may be intercepted and translucently processed. Processing such as dotted line processing, monochrome processing, or black and white processing. It should be understood that as long as the image data acquisition of the second view photo can be made different from the reference specific portion. Of course, the intercepted content can also be left unprocessed.

In the above step S206, it should be understood that when the mobile terminal performs the second view image data acquisition, the degree of matching between the image data in the current view frame and the reference partial image data is automatically detected, and when the matching degree reaches a certain preset value, That is, when the matching degree is high, the collection prompt information is displayed, and the user is reminded to perform image data collection and complete the second perspective image data acquisition or automatically perform image data collection according to the user acquisition instruction. In this way, it is more convenient for the user to collect the second view image data and form the stereo image data better with the first view image data. Of course, the preliminary second-view image data may be collected first, and the user may adjust the adjustment control command for the image data of the preliminary second-view image data, and the adjusted preliminary second-view image data is used as the second perspective image data. Specifically, it can be understood that the image data of the second perspective photo is collected first, the photo image data is temporarily stored, the image data is displayed on the display screen for the user to preview, and the user observation image data is compared with the characteristic partial image data, if found and The specific part of the image data has a certain deviation, which is adjusted by the control instruction, and when it is substantially coincident with the specific partial data image, it is related to the specific partial data. When the image matching is high, the preliminary second view image data is saved as the image data of the second view photo. The specific adjustment includes accepting the user's control instruction to perform the up, down, left and right translation of the preliminary second view image data, and the adjustment such as zooming in or out.

Hereinafter, all the image data of the image data of the first-view photo is taken as a reference, and the dotted image processing is performed on the reference image data as an example. Of course, it is not limited to selecting image data of all photos as a reference, and is not limited to performing a dotted line processing on a specific portion of the reference. The acquiring the second view photo image data is: calculating a specific portion matching degree of the second view image data and the first view image data, and completing the second view image data acquisition when the matching degree exceeds the preset value. As shown in FIG. 2b, the figure is image data of the first view photo taken, which includes a house and a tree. The entire photo may be selected as a reference for the second partial view photo as a specific partial image data, as shown in FIG. 2c, which is a reference image for image data acquisition of the second view photo after the dotted processing of the specific partial image data. When the second view image data is collected, as shown in FIG. 2d, when the image data of the photo of the second view substantially coincides with the reference dash image data, the image capture of the second view photo is completed. If the shooting target is just a house, I want to get a three-dimensional photo of the house. As shown in Figure 2e, when the house is only selected as a reference, the house is treated with a dotted line. As shown in FIG. 2f, when the photo image data collection of the second viewing angle is performed, when the reference house substantially coincides with the photographing house, the image acquisition of the second view photo is completed. When it is detected that the reference house and the shooting house substantially coincide, that is, the matching degree reaches more than 90%, the user may be reminded to perform image data collection of the second perspective photo or automatically perform image data collection of the second perspective photo.

In the above step 204, if the image data of the first perspective photo and the image data of the second perspective photo are separately collected, that is, after the image data of the first perspective photo is collected, the specific partial image data is displayed in the framing frame. Photo image acquisition for the second viewing angle. Of course, if the display screen of the mobile terminal is divided into a first view frame and a second view frame; the image data of the first view picture is collected by using the first view frame, and the first view image data is displayed in the first view frame; The image data of the second perspective photo is collected by using the second finder frame, and the specific partial image data is displayed in the second finder frame, and the image data collection of the second perspective photo is completed according to the reference.

In the above step 206, mainly the left-view image data and the right-view image data are combined to generate composite image data. This step can be imaged by other software and the mobile terminal itself. The basic operation is to complete the synthesis of the left-view image data and the right-view image data. Specifically, for example, the left and right viewing angle image data may be synthesized by editing and matching the left and right format three-dimensional image data; the left and right viewing angle image data may be converted into the combined raster format three-dimensional image data by the raster conversion application; and the left and right viewing angle image data will be converted by red and blue. The application converts the synthesized red and blue format 3D image data and the like.

Embodiment 3

In the following, the mobile terminal is taken as an example for the mobile phone. Of course, the mobile terminal is not limited to a mobile phone, such as a tablet computer, and the like is also included in the present invention. If a user needs to take a stereo photo with a mobile phone, the stereo photo application is launched, and of course, a stereo photo shooting portal can be added to the camera application.

As shown in Figures 3a and 3b, the interface layout of the left and right pictures is taken on a single screen. 3a is a schematic diagram of an interface for starting a stereo photo shooting application. 301 is the focus frame, the mobile phone camera is aimed at the shooting target, and the shooting target is clicked on the display screen of the mobile phone, and the camera program focuses on the target, and the shooting prompt is completed. 302 is the shooting target. 303 is a left eye image shooting button for capturing a left eye photo, that is, for collecting first angle photo image data. 304 is a right eye image shooting button for capturing a right eye photo, that is, for collecting first angle photo image data. 305 is a left eye diagram and a right eye diagram adaptation adjustment button for adjusting the position angle size of the left eye diagram and the right eye diagram photo, so that the left eye diagram and the right eye diagram photo are well adapted. 306 is a save button for saving stereo photos in a pair of left and right formats. The user clicks on the target that needs to be shot on the screen, and the mobile phone camera focuses on the target. After the focus is completed, the mobile phone prompts (such as sound, the focus frame is discolored), and the user presses the 303 left eye button to complete the left eye photo shooting. The user moves the mobile phone to the right in the horizontal direction by a certain distance, for example, moving 4-6cm, adjusting the shooting target to the same position in the left eye photo, clicking the target, and after the mobile phone finishes focusing, press the 304 right eye image shooting button to complete the right eye. take photo. If you are shooting with a professional horizontal mobile device, the left eye photo and the right eye photo can reproduce the photos seen by the left and right eyes very accurately.

When taking two photos by hand, it is necessary to keep the position of the shooting target in the frame in the same position, and the horizontal direction is the same, which is more difficult. To solve this problem, when taking the second photo, keep some of the photo information of the first photo on the screen, such as the photo in the focus frame of the first photo, for reference to the second photo. As shown in Figure 3b, the first left eye is taken when the second right eye photo is taken. The photos in the focus frame of the figure are retained on the display for shooting reference. The user takes the right eye image and pans the mobile phone 4-6cm. If the shooting target does not substantially coincide with the first photo, adjust the camera camera position angle, etc., so that the shooting target in the display screen and the left eye shooting target are basically coincident. The left eye image and the right eye image have a high degree of matching. Click the 304 right eye button to complete the right eye image. Of course, when shooting the right eye image, the mobile phone automatically calculates the matching degree between the left eye image and the reference scene on the display screen. When the matching degree reaches the preset value, the user is reminded to take the right eye image shooting, or can automatically shoot. . For example, the preset value can be 90%, that is, if the match is more than 90%, the shooting prompt information will be displayed or the shooting will be automatically performed. If the left eye image of the left eye is better adapted, click the 306 save button to generate a pair of stereo photos in the left and right format. After the right eye photo is taken, if the shooting target of the right eye image is found to be very different from the shooting target of the left eye image remaining in the display, click the 305 right and left adaptation button to make the right eye image in the photo adjustment state (or right eye). The photo adjustment status is automatically entered after the picture is taken. At this time, the right eye image can be moved up and down, left and right rotated, zoomed in and out, etc. to achieve matching between the right eye image and the left eye image. Finally, click the 306 Save button to generate a pair of stereo photos in left and right format.

As shown in Figures 3c and 3d, it is an interface layout diagram for taking pictures of left and right pictures in a dual screen. The display screen is divided into two left and right view frames, and 307 is a schematic diagram of the shooting target in the left eye image. The user clicks on the shooting target to complete the focus, and presses the shooting button to complete the left eye image shooting. Then, in the right frame, the screenshot in the target focus frame appears for the right eye to adjust the position reference. After the left eye image is taken, move the phone to the right by a certain distance. For example, you can move 4-6cm to take a right eye shot. 309 is an initial schematic diagram of the shooting target when the right eye image is taken. By adjusting the camera lens position, the image 309 and the image 308 are substantially coincident, the right eye framing is completed, and the focus shooting is performed. As shown in Fig. 3d, it is a stereoscopic picture in the left and right format (the two photos have a certain difference in viewing angle), and a very stereoscopic effect picture can be seen through the viewing screen.
