All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a video processing method. Referring to fig. 1, fig. 1 is a flowchart of a video processing method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
step 101, if a video layering instruction is received, acquiring depth-of-field information corresponding to each pixel point in each image frame of a video.
For example, a video layering touch button may be preset in a video playing interface, and if a touch operation for the video layering touch button is received, it is determined that a video layering instruction is received.
Optionally, when the video layering instruction is received, the depth of field information corresponding to each pixel point in each image frame of the video may be obtained through calculation, for example, the depth of field information corresponding to each pixel point in each image frame of the video is calculated through methods such as image shifting, continuous image prediction, and the like; or acquiring depth information corresponding to each pixel point in each image frame of the pre-stored video. The depth information may include a depth value, which may represent a distance of each object in the image frame from the camera.
And 102, layering the video according to the depth information corresponding to each pixel point in each image frame of the video to obtain at least two layers of sub-videos.
Specifically, the depth information corresponding to each pixel point in each image frame of the video may be compared with a threshold value, so as to determine the hierarchy to which each pixel point of each image frame belongs. For example, when the video needs to be divided into three layers, depth information corresponding to the pixel points of each image frame may be respectively compared with a first threshold and a second threshold, where the first threshold is smaller than the second threshold, the pixel points in each image frame whose depth information corresponding to the pixel points is smaller than or equal to the first threshold are divided into a first layer, the pixel points in each image frame whose depth information corresponding to the pixel points is greater than the first threshold and smaller than the second threshold are divided into a second layer, and the pixel points in each image frame whose depth information corresponding to the pixel points is greater than or equal to the second threshold are divided into a third layer.
Step 103, if a target operation instruction for a sub video of a target layer in the at least two layers of sub videos is received, processing the sub video of the target layer in the at least two layers of sub videos according to the target operation instruction, wherein the sub video of the target layer is a sub video of any one layer in the at least two layers of sub videos.
In the embodiment of the present invention, the target operation instruction may be reasonably set according to an actual situation, for example, the target operation instruction may be a pause operation instruction, a play operation instruction, a blurring operation instruction, and the like. It can be understood that, in the embodiment of the present invention, a target operation touch button corresponding to a target operation instruction may be preset in a video playing interface, and when a user touches the target operation touch button, a corresponding target operation instruction is generated.
Specifically, after the video is divided into three layers of sub-videos, each layered sub-video may be controlled separately, for example, after the video is divided into three layers of sub-videos, the sub-video of the first layer may be controlled to play, the sub-videos of the other two layers may be controlled to pause playing, or only the sub-video of the second layer may be subjected to blurring processing, or only the sub-video of the first layer may be subjected to filter processing, and the like.
In the embodiment of the present invention, the mobile terminal may be a mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a personal digital assistant (PDA for short), a Wearable Device (Wearable Device), or the like.
According to the video processing method, if a video layering instruction is received, depth of field information corresponding to each pixel point in each image frame of a video is obtained; layering the video according to depth information corresponding to each pixel point in each image frame of the video to obtain at least two layers of sub-videos; and if a target operation instruction for the sub-video of the target layer in the at least two layers of sub-videos is received, processing the sub-video of the target layer in the at least two layers of sub-videos according to the target operation instruction, wherein the sub-video of the target layer is the sub-video of any one layer in the at least two layers of sub-videos. The video is layered according to the depth of field information, and the sub-video of any one layer of the at least two layers of sub-videos obtained after the video is layered can be independently controlled, so that the video control mode is enriched, and the problems that the objects of different layers in the video picture cannot be independently controlled and the video processing mode is single in the prior art are solved.
Referring to fig. 2, fig. 2 is a flowchart of a video processing method according to an embodiment of the present invention. The difference between the embodiment of the present invention and the previous embodiment is mainly that the depth information corresponding to each pixel point in each image frame is further limited to be calculated in the process of recording the video. In an embodiment of the present invention, before the step 101, the method further includes: in the process of recording a video through a camera of the mobile terminal, respectively calculating depth-of-field information corresponding to each pixel point in each image frame acquired by the camera of the mobile terminal; and respectively storing the depth information corresponding to each pixel point in each image frame and the corresponding pixel point in an associated manner.
As shown in fig. 2, the video processing method provided by the embodiment of the present invention includes the following steps:
step 201, in the process of recording a video through a camera of a mobile terminal, respectively calculating depth-of-field information corresponding to each pixel point in each image frame acquired by the camera of the mobile terminal.
In the embodiment of the invention, the depth of field information corresponding to each pixel point in each image frame acquired by the camera of the mobile terminal can be calculated in the process of recording the video.
Optionally, in order to improve the accuracy of the depth-of-field information obtained by the calculation, the mobile terminal at least includes a first camera and a second camera, the first camera and the second camera are arranged in parallel on the same side of the mobile terminal along a target direction, and focal lengths of the first camera and the second camera are the same, the target direction is the width direction of the mobile terminal or the length direction of the mobile terminal, in step 201, that is, in the process of recording a video by the camera of the mobile terminal, the depth-of-field information corresponding to each pixel point in each image frame acquired by the camera of the mobile terminal is calculated respectively, including:
in the process of recording videos through the first camera and the second camera, respectively acquiring image frames, which are acquired by the first camera and the second camera at the same moment and aim at the same object, and acquiring a first image frame and a second image frame;
determining the objects separatelyThe target coordinate X of the corresponding pixel point in the first image frameaAnd target coordinates X in said second image framebWherein the target coordinates are coordinates along the target direction;
by usingCalculating the depth of field value corresponding to the pixel point corresponding to the object;
wherein D represents a depth of field value corresponding to a pixel point corresponding to the object, f represents a focal length of the first camera or a focal length of the second camera, and T represents a distance interval between the first camera and the second camera.
In the embodiment of the invention, the mobile terminal at least comprises a first camera and a second camera, wherein the first camera is arranged on the same side of the mobile terminal in parallel along the target direction. For example, referring to fig. 3, the mobile terminal 1 includes a first camera 11 and a second camera 12, the first camera 11 and the second camera 12 being disposed in parallel on the front or back of the mobile terminal 1 in the width direction of the mobile terminal 1, referring to fig. 4, the mobile terminal 1 includes a first camera 11 and a second camera 12, the first camera 11 and the second camera 12 being disposed in parallel on the front or back of the mobile terminal 1 in the length direction of the mobile terminal 1. The focal lengths of the first camera and the second camera are the same, and as shown in fig. 5, the distance interval between the first camera 11 and the second camera 12 is T.
Taking the first camera and the second camera arranged in parallel in the width direction of the mobile terminal as an example, when receiving a video recording instruction, the first camera and the second camera may be started to simultaneously acquire image frames, as shown in fig. 6, to obtain a first image frame 111 and a second image frame 121 shown in fig. 7 and 8, respectively, where pixel points corresponding to the same object P exist in the first image frame 111 and the second image frame 121. Fig. 9 is a schematic diagram of calculating depth of field information of the object P, see fig. 9, where T is a distance interval between the first camera and the second camera, and f is a focal length of the first camera or the second camera, where the focal lengths of the first camera and the second cameraSame distance, XaAs the abscissa, X, of the object P in the first image framebAs the abscissa of the object P in the second image frame, the triangle PPaPb and the triangle POaOb are two similar triangles as can be seen from fig. 9, and are obtained according to the similar triangle principle:
from the above equation:
that is, the distance from the object P to the camera is D — Z-f, which is the depth of field value corresponding to the pixel point corresponding to the object P.
The embodiment of the invention can adopt the mode to respectively calculate the depth of field value corresponding to each pixel point in the image frame. It can be understood that, in the embodiment of the present invention, after the depth of field value corresponding to each pixel point in the image frame is obtained through calculation, only the image frame acquired by the first camera or the image frame acquired by the second camera may be stored, so as to reduce the occupation of the storage space.
According to the embodiment of the invention, the two cameras are used for collecting the image frames aiming at the same object at the same time so as to calculate the depth of field information corresponding to the pixel points corresponding to all objects in the image frames, and the accuracy of the depth of field information corresponding to each pixel point in each image frame obtained by calculation can be improved.
Step 202, respectively storing each pixel point in each image frame, depth of field information corresponding to each pixel point in each image frame, and an association relationship between the depth of field information corresponding to each pixel point in each image frame and the corresponding pixel point.
Specifically, each image frame collected by the camera and the depth information corresponding to each pixel point of the image frame can be packaged into one frame of data, where the depth information corresponding to each pixel point can be represented as D (x, y), where (x, y) represents a position of the object in the image frame, that is, a position of a pixel point corresponding to the object in the image frame, and D represents the depth information corresponding to the object, that is, the depth information corresponding to the pixel point corresponding to the object.
Step 203, if a video layering instruction is received, acquiring depth-of-field information corresponding to each pixel point in each image frame of the video.
In the embodiment of the invention, when the video layering command is received, the depth of field information corresponding to each pixel point in each stored image frame can be acquired, so that the acquisition efficiency of the depth of field information can be improved, and the video layering efficiency is further improved.
And 204, layering the video according to the depth information corresponding to each pixel point in each image frame of the video to obtain at least two layers of sub-videos.
In the embodiment of the invention, a plurality of threshold values for video layering can be preset, and the layer to which each pixel point in each image frame belongs can be determined by comparing the threshold values with the depth information corresponding to each pixel point in each image frame of the video.
Optionally, in order to improve the flexibility of video layering, in step 204, that is, layering the video according to the depth information corresponding to each pixel point in each image frame of the video, to obtain at least two layers of sub-videos, the method includes:
acquiring the layering number and the layering distance;
and layering the video according to the layering number, the layering distance and depth information corresponding to each pixel point in each image frame of the video to obtain the sub-videos with the layering number.
In the embodiment of the invention, the layering number and the layering distance can be reasonably set by a user. Specifically, when a video layering instruction is received, a setting interface is popped up for a user to set the layering number and the layering distance. It is understood that the number of layers and the distance between layers may be preset.
As an example, the number of layers is n, and the layer distances are d1, d2, d3, and … dn, the depth information (i.e., depth value) corresponding to the i-th layer is:
wherein i is 1,2,3, …, n, d0=0,dnBy this means, all the image regions Σ (x, y) corresponding to the i-th layer can be obtained from D (x, y).
For example, when n is 3, d1 is 1m, d2 is 10m, and d3 is 20m, the depth of field interval of each layer may be as follows:
the depth of field interval of the first layer is: d is more than or equal to 0 and less than 5.5;
the depth of field interval of the second layer is as follows: d is more than or equal to 5.5 and less than 15;
the depth of field interval of the third layer is as follows: 15 is less than or equal to D and less than infinity.
Specifically, each image frame of the video may be divided into 3 layers of sub-images by the 3 layers of depth intervals, for example, as shown in fig. 10, the first image frame 111 is divided into 3 layers of sub-images, which are the first layer sub-image 1111, the second layer sub-image 1112, and the third layer sub-image 1113, respectively. It is to be understood that the first layer, the second layer sub-image 1112 and the third layer sub-image 1113 are only used for representing different image layers, and the order of the layers is not limited. Specifically, the video playing interface after video layering may display an operation interface to receive an operation instruction, where the operation interface may be as shown in fig. 11.
According to the embodiment of the invention, the video is layered according to the layering number, the layering distance and the depth of field information corresponding to each pixel point in each image frame of the video, so that the video layering can be flexibly controlled according to actual requirements.
Optionally, in order to improve the video layering effect, in step 204, that is, layering the video according to the depth information corresponding to each pixel point in each image frame of the video, to obtain at least two layers of sub-videos, the method includes:
dividing image areas of each image frame of the video to obtain at least two image areas corresponding to each image frame of the video;
determining a layer to which each image area in at least two image areas corresponding to each image frame of the video belongs according to depth information corresponding to the pixel point of each image area in at least two image areas corresponding to each image frame of the video;
and layering the video according to the layer to which each image area belongs in at least two image areas corresponding to each image frame of the video to obtain at least two layers of sub-videos.
In an actual situation, when a video is layered according to depth information, if an object is large, there may be a case where a pixel point belonging to the object belongs to different layers, thereby affecting a display effect of a sub-video obtained by layering the video. For example, after videos are layered, one part of a bus in the videos belongs to a sub-video of a first layer, and the other part of the videos belongs to a sub-video of a second layer, so that when the sub-video of the first layer is played alone or the sub-video of the second layer is played alone, the bus picture is incomplete, and the display effect is affected.
In the embodiment of the invention, the image area division can be performed on each image frame, for example, the contour of each object in the image frame can be detected, and the image frame can be divided into different image areas according to the contour of each object. After dividing an image region of a certain image frame to obtain at least two image regions, the layer to which each image region belongs may be determined, for example, the number of pixel points belonging to each layer in each image region may be counted, and the layer including the largest number of pixel points of the image region is determined as the layer to which the image region belongs. Specifically, after a layer to which each image region of each image frame of the video belongs is obtained, each image frame of the video may be layered respectively to obtain a sub-image frame of each image frame, and the sub-image frames belonging to the same layer in all the image frames of the video constitute the sub-video of the layer.
According to the embodiment of the invention, each image frame of the video is divided into the image areas, and the video is layered according to the layer to which each image area belongs in at least two image areas corresponding to each image frame of the video, so that the image areas of the same object can be ensured to be positioned in the same layer, and the display effect of the sub-video obtained after the video is layered can be improved.
Step 205, if a target operation instruction for a sub video of a target layer in the at least two layers of sub videos is received, processing the sub video of the target layer in the at least two layers of sub videos according to the target operation instruction, where the sub video of the target layer is a sub video of any one layer in the at least two layers of sub videos.
In the embodiment of the present invention, the target operation instruction may be reasonably set according to an actual situation, for example, the target operation instruction may be a pause operation instruction, a play operation instruction, a blurring operation instruction, and the like. It can be understood that, in the embodiment of the present invention, a target operation touch button corresponding to a target operation instruction may be preset in a video playing interface, and when a user touches the target operation touch button, a corresponding target operation instruction is generated.
Optionally, in step 205, that is, if the target operation instruction for the sub-video of the target layer in the at least two layers of sub-videos is received, processing the sub-video of the target layer in the at least two layers of sub-videos according to the target operation instruction includes:
when the target operation instruction comprises a playing control instruction, playing the sub-video of the target layer;
when the target operation instruction comprises a pause playing control instruction, pausing playing of the sub-video of the target layer;
when the target operation instruction comprises a blurring operation instruction, performing blurring processing on the sub video of the target layer;
and when the target operation instruction comprises a filter operation instruction, performing filter processing on the sub-video of the target layer.
In practical application, after the videos are layered to obtain at least two layers of sub-videos, the sub-video of any one of the at least two layers of sub-videos may be individually played and controlled, and the sub-videos of other layers are controlled to be in a paused state, for example, when a user wants to observe the activity of an object (e.g., a layer where a person in the video is located) in a first layer of a video picture, the sub-video of a second layer and the sub-video of a third layer may be paused, so that the user may concentrate on observing the activity of the person in the first layer, and eliminate interference caused by the objects in other layers. For example, the playback of the second-floor car and the third-floor mountain shown in fig. 11 is paused, and only the moving picture of the person of the first floor is played.
Optionally, the embodiment of the present invention may also perform blurring processing on the sub-videos, for example, when the user touches the blurring button shown in fig. 11, one or more layers of sub-videos may be blurred, and other layers do not perform blurring processing, so that an effect of highlighting a picture of one layer may be achieved, and a car of the second layer and a peak of the third layer are blurred, and only a picture of a person of the first layer is clear.
