Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
At present, when a depth image is obtained, a binocular stereo vision method is generally adopted for obtaining, two cameras are needed to be arranged in the method, two images of the same scene can be obtained simultaneously through the two cameras, corresponding pixel points in the two images are found through a stereo matching algorithm, parallax information is calculated according to a triangular principle, and the parallax information is converted into the depth image which can be used for representing the object distance in the scene.
In the method for obtaining the depth image, the cameras need to be assembled at certain intervals and fixed by the support, and need to be calibrated, so that the assembly of the cameras is complex. Particularly, in the selection of the bracket, if the metal bracket is used for fixing the camera, the transmission of radio frequency signals can be influenced; if fix the camera with non-metallic support, then probably need use the great support of thickness just can guarantee the higher stability of camera, this to the terminal that needs to realize frivolous design, will increase the design degree of difficulty of terminal structure undoubtedly.
In the embodiment of the application, the depth image is directly acquired by arranging the 3D camera when the image is shot, and the two cameras are not required to be used for acquiring the depth image, so that the camera can be fixed without a support and calibrated, the assembly flow of the camera is simplified, the assembly efficiency of the camera is improved, and the difficulty of the structural design of the terminal is not increased.
In addition, in practical application, when the 3D camera outputs a two-dimensional RGB image and a depth image carrying depth information, the higher the depth accuracy corresponding to the depth image is, the more the resolution of the two-dimensional RGB image is reduced obviously, and the requirement of a user on the image resolution cannot be met. To this, this application embodiment has still realized carrying out the acquirement of first shooting image through the RGB camera when the mode of shooing is first preset mode through setting up the RGB camera when setting up the 3D camera, has avoided utilizing the 3D camera to carry out image shooting, leads to the resolution ratio of image shooting can't satisfy the problem of user's demand.
Fig. 1 shows a schematic flow chart of a photographing method implemented by an embodiment of the present application, where the method is applied to a terminal, can be executed by a photographing device configured on the terminal, and is suitable for a situation where camera assembly efficiency needs to be improved, and includes steps 101 to 103.
The terminal comprises a terminal provided with a photographing device, such as a smart phone, a tablet computer and a learning machine. This terminal can install and take a picture and use to be provided with two cameras, two cameras include 3D camera and RGB camera.
The 3D camera can simultaneously output a two-dimensional RGB image and a depth image carrying depth information when shooting; the RGB camera can output a two-dimensional RGB image with high resolution ratio when shooting.
Optionally, in some embodiments of the present application, the current photographing mode of the terminal may be obtained when a camera start instruction is received.
For example, the camera start instruction includes a camera start instruction triggered by a user clicking a shooting application icon in a system desktop, a camera start instruction triggered by a user through a point physical key, a camera start instruction triggered by a user through voice, or a camera start instruction triggered by other ways.
Optionally, in some embodiments of the application, the current photographing mode of the terminal may also be obtained when the photographing instruction is received.
For example, as shown in fig. 2, when a photographing instruction triggered by a user clicking the photographing control 22 in the photographing preview interface 21 is received, the current photographing mode of the terminal is acquired; or when a photographing instruction triggered by clicking a physical key by a user is received, acquiring the current photographing mode of the terminal; or when a photographing instruction triggered by voice of a user is received, acquiring the current photographing mode of the terminal; here, the triggering manner of the photographing instruction is not limited in the embodiment of the present application.
Optionally, the photographing mode may include one or more of a first preset photographing mode, a second preset photographing mode, and a third preset photographing mode. The first preset shooting mode is a mode for starting an RGB camera to shoot; the second preset shooting mode is a mode for starting the 3D camera to shoot; the third preset shooting mode is a shooting mode for simultaneously starting the RGB camera and the 3D camera.
Optionally, the shooting mode of the terminal may be set according to a received setting instruction triggered by the user in the shooting preview interface.
For example, as shown in fig. 2, the shooting mode of the terminal may be a setting instruction of the first preset shooting mode triggered by selecting the selection control 25 in the pop-up window 24, a setting instruction of the second preset shooting mode triggered by selecting the selection control 26, and a setting instruction of the third preset shooting mode triggered by selecting the selection control 27, according to the received setting instruction of the first preset shooting mode triggered by the user clicking the setting control 23 in the shooting preview interface 21.
And step 102, if the photographing mode is a first preset mode, starting the RGB camera to acquire a first photographed image.
In the embodiment of the application, after the current photographing mode of the terminal is obtained, if the photographing mode is the first preset mode, it indicates that the user only needs to photograph the two-dimensional RGB image, and therefore, the requirement of the user on photographing the image with higher resolution can be met by independently starting the RGB camera to photograph the two-dimensional RGB image.
For example, when a user needs to perform self-photographing or normal picture photographing, the photographing mode may be set to a first preset mode, so that the RGB camera is turned on to obtain a first photographed image when the terminal receives a photographing instruction, or the RGB camera is turned on when image preview is performed, and the RGB camera is turned on to obtain the first photographed image when the photographing instruction is received.
In the embodiment of the application, when the user needs to acquire the two-dimensional RGB image and the depth image carrying the depth information at the same time, the photographing mode can be set to be the second preset mode, so that the photographing instruction is received at the terminal and then the 3D camera acquires the second photographed image and the depth image, or the 3D camera is started when the image is previewed and simultaneously acquires the second photographed image and the depth image when the photographing instruction is received.
In the embodiment of the application, through setting up the two cameras including 3D camera and RGB camera, can provide two kinds of independent shooting modes respectively for the user, promptly, first mode and the second mode of predetermineeing are preset. Under the two shooting modes, the two cameras work independently and are in complementary interference, when the 3D camera is started, the RGB camera is not started, and when the RGB camera is started, the 3D camera is not started; and the opening of the two cameras can be controlled through the shooting mode selected by the user, so that the automatic switching control system has the characteristic of flexible control mode and can realize the automatic switching between the two cameras according to the requirements of the user.
In addition, because the work of the two cameras is independent and does not influence each other, the two cameras can be fixed without a support, the distance between the two cameras is not limited, and meanwhile the two cameras do not need to be calibrated, so that the assembly process of the cameras is simplified, and the assembly efficiency of the cameras is improved.
Optionally, in step 103, after the acquiring the second captured image and the first depth image, the method may further include: and outputting a three-dimensional image according to the second shot image and the first depth image.
For example, when 3D makeup is performed, in order to blend the virtual makeup with the collected user image more naturally, the second captured image and the depth image may be acquired simultaneously by turning on the 3D camera, and a corresponding three-dimensional image may be output.
As an embodiment of the present application, as shown in fig. 3, after the current photographing mode of the terminal is obtained, steps 104 to 105 may further be included.
And step 104, if the photographing mode is a third preset mode, simultaneously starting the RGB camera and the 3D camera, and respectively acquiring the first photographed image, the second photographed image and the first depth image.
And 105, mapping the depth information carried by the first depth image to the first shot image to obtain the first shot image carrying the depth information.
Because the 3D camera itself can output two-dimensional RGB image and depth image simultaneously, consequently, when needing to acquire three-dimensional image, only need open a 3D camera and carry out image shooting can. However, in practical applications, when the 3D camera outputs a two-dimensional RGB image and a depth image carrying depth information, the higher the depth accuracy corresponding to the depth image, the more the resolution of the two-dimensional RGB image is reduced, and therefore, when it is necessary to acquire a three-dimensional image with high resolution and high depth accuracy, it is impossible to acquire a three-dimensional image by directly outputting the two-dimensional RGB image and the depth image using the 3D camera.
In the embodiment of the application, by integrating respective advantages of a 3D camera and the RGB camera, the RGB camera and the 3D camera are simultaneously started to obtain a first shot image, a second shot image and a first depth image, and then depth information carried by the first depth image is mapped into the first shot image to obtain the first shot image carrying the depth information, so that a three-dimensional image with higher resolution and higher depth precision can be obtained according to the first shot image carrying the depth information; the problem that the resolution ratio of image shooting cannot meet the requirements of users due to the fact that the 3D camera is used for image shooting is avoided.
In some embodiments of the present application, as shown in fig. 4, the step 105 of mapping the depth information carried by the first depth image to the first captured image to obtain the first captured image carrying the depth information may include: step 401 to step 403.
Step 401, performing alignment transformation and clipping processing on the first shot image and the second shot image to obtain a third shot image corresponding to the first shot image and a fourth shot image corresponding to the second shot image; and pixels in the third shot image correspond to pixels in the fourth shot image one to one.
For example, the first captured image and the second captured image are subjected to alignment transformation and cropping processing using an alignment algorithm so that pixels in the third captured image correspond one-to-one to pixels in the fourth captured image. The alignment algorithm may be a general alignment algorithm, such as a forward addition algorithm and an inverse combination algorithm.
And 402, performing the same alignment transformation and cutting processing as the second shot image on the first depth image to obtain a second depth image.
And step 403, mapping the depth information of the second depth image to the third shot image to obtain a third shot image carrying the depth information.
Since the first depth image and the second captured image are images output by the 3D camera at the same time, the captured contents are the same, and therefore, after the fourth captured image is obtained by performing the alignment transformation and cropping processing on the second captured image, the first depth image is subjected to the alignment transformation and cropping processing using the same alignment transformation and cropping processing as the second captured image, so that the second depth image can be obtained in one-to-one correspondence with the fourth captured image, that is, in one-to-one correspondence with the third captured image. Therefore, the first depth image needs to be subjected to the same alignment transformation and clipping processing as the second captured image to obtain a second depth image, so that the depth information of the second depth image can be mapped to the third captured image to obtain a third captured image carrying the depth information.
Optionally, before simultaneously turning on the RGB camera and the 3D camera, the method includes: and adjusting the depth precision of the 3D camera to a maximum value so as to obtain a three-dimensional image with higher depth precision as far as possible.
Optionally, in the embodiment described in fig. 1, in step 103, if the photographing mode is a second preset mode, turning on the 3D camera to obtain a second photographed image and a first depth image may include: and if the photographing mode is a second preset mode, after the depth precision of the 3D camera is adjusted to a preset precision value, the 3D camera is started to obtain a second photographed image and a first depth image.
When the photographing mode is the second preset mode, it cannot be determined whether the depth precision of the 3D camera is set to the maximum value or other depth precisions, and therefore, when the photographing mode is determined to be the second preset mode, the depth precision of the 3D camera needs to be adjusted to a preset precision value, and then the 3D camera is started to obtain the second photographed image and the first depth image.
The preset precision can be a depth precision when the depth precision and the resolution of the image reach an equilibrium state. For example, the preset depth accuracy may be obtained experimentally.
Optionally, in some embodiments of the present application, in step 103, turning on the 3D camera to obtain the second captured image and the first depth image may further include: and receiving a depth precision setting instruction, and acquiring a second shot image and a first depth image according to the depth precision corresponding to the depth precision setting instruction.
For example, as shown in fig. 5, when the photographing mode is the second preset mode, a depth precision setting bar 51 may be displayed on the photographing preview interface 21, a depth precision setting instruction generated according to a sliding operation of a user on a slider 52 on the depth precision setting bar 51 is received, and a second photographed image and a first depth image are obtained according to the depth precision corresponding to the depth precision setting instruction, so that dynamic adjustment between resolution and depth precision of a three-dimensional image output according to the second photographed image and the first depth image is realized, so as to meet different photographing requirements of the user.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
