Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

At present, when acquiring depth images, the method of binocular stereo vision is usually used. This method needs to set up two cameras, and the two cameras can simultaneously acquire two images of the same scene, and find the two images through a stereo matching algorithm. Then, the disparity information is calculated according to the triangulation principle, and the disparity information is converted into a depth image that can be used to represent the distance of objects in the scene.

In this method of acquiring a depth image, the assembly of the camera needs to be separated by a certain distance, and at the same time, it needs to be fixed with a bracket, and the camera needs to be calibrated, and the assembly of the camera is relatively complicated. Especially in the selection of brackets, if a metal bracket is used to fix the camera, it may affect the transmission of radio frequency signals; if a non-metal bracket is used to fix the camera, a bracket with a thicker thickness may be required to ensure the higher stability of the camera This will undoubtedly increase the design difficulty of the terminal structure for terminals that need to achieve thin and light designs.

In the embodiment of the present application, by setting the 3D camera to directly obtain the depth image when the image is captured, it is not necessary to use two cameras to obtain the depth image. Therefore, it is not necessary to use a bracket to fix the camera and calibrate the camera, which simplifies The assembly process of the camera is improved, the assembly efficiency of the camera is improved, and the difficulty of terminal structure design is not increased.

In addition, in practical applications, when a 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 obvious the decrease in the resolution of the two-dimensional RGB image. rate requirements. In this regard, the embodiment of the present application also sets the RGB camera when the 3D camera is set, so that when the photographing mode is the first preset mode, the RGB camera can be used to obtain the first photographed image, avoiding the need to use the 3D camera to obtain the first photographed image. Image capture, resulting in the problem that the resolution of the image capture cannot meet the needs of users.

FIG. 1 shows a schematic diagram of the implementation flow of a photographing method provided by an embodiment of the present application. 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 the assembly efficiency of a camera needs to be improved. The method includes steps 101 to 101 Step 103.

Wherein, the above-mentioned terminal includes a terminal equipped with a photographing device, such as a smart phone, a tablet computer, and a learning machine. The terminal may be installed with a camera application and provided with dual cameras, the dual cameras include a 3D camera and an 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 higher resolution when shooting.

Step 101: Obtain the current photographing mode of the terminal.

Optionally, in some embodiments of the present application, the current photographing mode of the terminal may be acquired when a camera startup instruction is received.

For example, the above-mentioned camera startup instructions include camera startup instructions triggered by the user clicking on the camera application icon on the system desktop, camera startup instructions triggered by the user pressing a physical button, camera startup instructions triggered by the user through voice, or camera startup instructions triggered by other means.

Optionally, in some embodiments of the present application, the current photographing mode of the terminal may also be acquired when a photographing instruction is received.

For example, as shown in FIG. 2, when receiving a photographing instruction triggered by the user clicking on the photographing control 22 in the photographing preview interface 21, the current photographing mode of the terminal is obtained; or when receiving a photographing instruction triggered by the user by clicking a physical button, Obtain the current photographing mode of the terminal; or, when receiving a photographing instruction triggered by the user through voice, obtain the current photographing mode of the terminal; this is just an example, and in this embodiment of the present application, the triggering method of the photographing instruction is not limited .

Optionally, the above-mentioned 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 photographing mode is a mode in which an RGB camera is turned on for shooting; the second preset photographing mode is a mode in which a 3D camera is turned on for shooting; the third preset photographing mode is a mode in which the RGB camera and the 3D camera are simultaneously turned on shooting mode.

Optionally, the shooting mode of the terminal may be set according to the received setting instruction triggered by the user in the photographing preview interface.

For example, as shown in FIG. 2 , the shooting mode of the terminal may be based on the received user clicking the setting control 23 in the shooting preview interface 21 , and then selecting the first preset shooting mode triggered by the selection control 25 in the pop-up window 24 . For the setting instruction, the setting instruction of the second preset photographing mode triggered by the selection control 26 is selected, and the setting instruction of the third preset photographing mode triggered by the selection control 27 is selected.

Step 102: If the photographing mode is the first preset mode, turn on the RGB camera to obtain a first photographed image.

In this embodiment of the present application, after obtaining the current photographing mode of the terminal, if the photographing mode is the first preset mode, it means that the user only needs to photograph two-dimensional RGB images. Therefore, the RGB camera can be turned on independently Shoot two-dimensional RGB images to meet the user's requirements for shooting higher-resolution images.

For example, when the user needs to take a selfie or take a normal picture, the camera mode can be set to the first preset mode, so that when the terminal receives the camera instruction, the RGB camera is turned on to obtain the first captured image, or when the image is taken When previewing, the RGB camera is turned on, and the first shot image is acquired by the RGB camera when a photographing instruction is received.

Step 103: If the photographing mode is the second preset mode, turn on the 3D camera to obtain a second photographed image and a first depth image.

In the embodiment of the present application, when the user needs to obtain a two-dimensional RGB image and a depth image carrying depth information at the same time, the camera mode can be set to the second preset mode, so that the 3D camera can be turned on when the terminal receives a camera instruction Acquire the second captured image and the depth image, or, when performing image preview, turn on the 3D camera, and simultaneously acquire the second captured image and the depth image by the 3D camera when receiving a photographing instruction.

In the embodiment of the present application, by setting a dual camera including a 3D camera and an RGB camera, two independent shooting modes can be provided for the user, that is, the first preset mode and the second preset mode. In these two shooting modes, the two cameras work independently and interfere with each other. When the 3D camera is turned on, the RGB camera is not turned on, and when the RGB camera is turned on, the 3D camera is not turned on; The opening can be controlled by the shooting mode selected by the user, which has the characteristics of flexible control mode, and can automatically switch between the two according to user needs.

In addition, because the work of the two cameras is independent of each other and does not affect each other, therefore, the two cameras do not need to be fixed with a bracket, and there is no distance limit between the two, and there is no need for the two cameras. The camera is calibrated, which simplifies the assembly process of the camera and improves the assembly efficiency of the camera.

Optionally, in the foregoing step 103, after the acquiring the second captured image and the first depth image, the method may further include: outputting a three-dimensional image according to the second captured image and the first depth image.

For example, when performing 3D beauty makeup, in order to make the virtual makeup look more natural with the captured user image, the 3D camera can be turned on to simultaneously acquire the second captured image and the depth image, and output the corresponding 3D image.

As an implementation manner of the present application, as shown in FIG. 3 , after acquiring the current photographing mode of the terminal, steps 104 to 105 may be further included.

Step 104 , if the photographing mode is the third preset mode, turn on the RGB camera and the 3D camera at the same time, and acquire the first photographed image, the second photographed image, and the first depth image respectively.

Step 105: Map the depth information carried by the first depth image to the first captured image to obtain a first captured image carrying depth information.

Since the 3D camera itself can output a two-dimensional RGB image and a depth image at the same time, when a three-dimensional image needs to be acquired, only one 3D camera needs to be turned on for image capture. However, in practical applications, when a 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 obvious the decrease in the resolution of the two-dimensional RGB image. For 3D images with higher resolution and higher depth accuracy, the 3D camera cannot be used to directly output 2D RGB images and depth images to obtain 3D images.

In the embodiment of the present application, by combining the respective advantages of the 3D camera and the RGB camera, the RGB camera and the 3D camera are turned on at the same time, the first captured image, the second captured image and the first depth image are acquired, and then the Mapping the depth information carried by the first depth image to the first captured image to obtain a first captured image carrying depth information, so as to obtain a higher resolution and deeper depth according to the first captured image carrying depth information High-precision 3D image; avoids the problem of using 3D camera for image capture, resulting in the problem that the resolution of the image capture cannot meet the needs of users.

Since the distance between the first camera and the second camera may be relatively large, the shooting content of the first captured image and the second captured image may be inconsistent. Therefore, in the present application In some embodiments, as shown in FIG. 4 , in the above step 105, the depth information carried by the first depth image is mapped to the first captured image to obtain the first captured image carrying depth information, which may include the following steps: 401 to step 403 .

Step 401: Perform alignment transformation and cropping processing on the first captured image and the second captured image to obtain a third captured image corresponding to the first captured image, and a third captured image corresponding to the second captured image. Four captured images; the pixels in the third captured image correspond one-to-one with the pixels in the fourth captured image.

For example, using an alignment algorithm to perform alignment transformation and cropping processing on the first captured image and the second captured image, so that the pixels in the third captured image correspond one-to-one with the pixels in the fourth captured image. Wherein, the alignment algorithm may be a general alignment algorithm, for example, a forward addition algorithm and an inverse combination algorithm.

Step 402: Perform the same alignment transformation and cropping processing on the first depth image as the second captured image to obtain a second depth image.

Step 403: Map the depth information of the second depth image to the third captured image to obtain a third captured image carrying 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. Therefore, after the second captured image is aligned, transformed and cropped to obtain the fourth captured image, The first depth image is aligned, transformed and cropped using the same alignment transformation and cropping process as the second captured image, so that the obtained second depth image can be in a one-to-one correspondence with the fourth captured image, that is, One-to-one correspondence with the third captured images. Therefore, it is necessary to perform the same alignment transformation and cropping processing on the first depth image 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 image to obtain a third shot image carrying depth information.

Optionally, before turning on the RGB camera and the 3D camera at the same time, the method includes: adjusting the depth accuracy of the 3D camera to a maximum value, so as to obtain a three-dimensional image with higher depth accuracy as much as possible.

Optionally, in the embodiment described in FIG. 1 above, in step 103, if the photographing mode is the second preset mode, turning on the 3D camera to obtain the second photographing image and the first depth image may include: : If the photographing mode is the second preset mode, after adjusting the depth accuracy of the 3D camera to a preset accuracy value, the 3D camera is turned on to obtain the second photographed image and the first depth image.

Because when the photographing mode is the second preset mode, it cannot be determined whether the depth accuracy of the 3D camera has been set to the maximum value or other depth accuracy at this time. Therefore, when it is determined that the photographing mode is the second preset mode When the depth accuracy of the 3D camera is adjusted to a preset accuracy value, the 3D camera is turned on to obtain the second captured image and the first depth image.

The preset precision may be the depth precision when the depth precision and the resolution of the image reach a balanced state. For example, the preset depth accuracy can be obtained according to experiments.

Optionally, in some embodiments of the present application, in the above step 103, turning on the 3D camera to obtain the second captured image and the first depth image may further include: receiving a depth accuracy setting instruction, setting the depth accuracy according to the depth accuracy. The second captured image and the first depth image are acquired with the depth precision corresponding to the instruction.

For example, as shown in FIG. 5 , when the photographing mode is the second preset mode, a depth accuracy setting bar 51 may be displayed on the photographing preview interface 21 , and a user's sliding motion on the depth accuracy setting bar 51 may be received. The depth accuracy setting instruction generated by the sliding operation of block 52 is obtained, and the second captured image and the first depth image are acquired according to the depth accuracy corresponding to the depth accuracy setting instruction, so as to realize the second captured image and the first depth image according to the depth accuracy setting instruction. Dynamic adjustment between the resolution and depth accuracy of the 3D image output from the image to meet the different shooting needs of users.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
