Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
Referring to fig. 1, fig. 1 is a flowchart of an image processing method provided in an embodiment of the present invention, where the method is applied to a terminal including a first camera and a second camera, where the first camera and the second camera are located on a same side of the terminal, and as shown in fig. 1, the method includes the following steps:
The first camera may be a Time Of Flight (TOF) camera, the second camera may be a color camera, and the color camera may also be referred to as an RGB camera.
The shot object may include a background object and a target object, for example: the target object may be a human face and the background object may be a wall surface and a landscape painting hung on the wall surface.
The first image is an image in a video acquired by the first camera with respect to the subject, and the second image is an image in a video acquired by the second camera with respect to the subject.
When the first image is an image in a video acquired by the first camera with respect to the object, and the second image is an image in a video acquired by the second camera with respect to the object, the first image and the second image may be images acquired at the same time with respect to the same object, for example: the first image is an image obtained by the terminal for the first scene through the first camera at the first time, and the second image may be an image obtained by the terminal for the first scene through the second camera at the first time.
In addition, the first image and the second image are both images in the video, so that the background object of each frame of the second image in the video can be removed, and then the second image can be synthesized with other videos comprising scenes to be synthesized.
In this embodiment, the first image is an image in a video acquired by the first camera with respect to the photographed object, and the second image is an image in a video acquired by the second camera with respect to the photographed object, which can be applied to removing a background object of each frame of image in the video, so that the application range of this embodiment is wider, and the use is more flexible.
102, obtaining depth information and/or angle information in the first image, and identifying a background object in the shot object according to the depth information and/or the angle information, wherein the angle information is as follows: angle information of each position in the subject with respect to the first camera.
And the depth information in the first image is not in the preset range, and/or each position of which the angle information is larger than the preset angle threshold value forms a background object. For example: the preset range may be 1 meter to 10 meters, and the preset angle threshold may be 45 degrees.
It should be noted that the preset range may refer to a range between a value greater than or equal to a first value and a value less than or equal to a second value, where a value of the second value is related to the accuracy of the first camera, and the higher the accuracy of the first camera is, the higher the value of the second value is.
In addition, the angle information of each position in the object may be specifically: the camera comprises a connecting line between each position and the first camera and an included angle between reference straight lines, wherein the reference straight lines are straight lines which pass through the first cameras and are perpendicular to one surface of the terminal, on which the first cameras are arranged. For example: referring to fig. 2, in the drawing, a point a is a position of the first camera, B is a certain position in the object to be photographed, C is another position in the object to be photographed, a straight line where a connecting line between a and D is a reference straight line, wherein angle information of the point B is an included angle between a straight line where the point AB is located and a straight line where the point AD is located, angle information of the point C is an included angle between a straight line where the point AC is located and a straight line where the point AD is located, an included angle between a straight line where the point AE is located and a straight line where the point AD is located may represent a preset angle threshold, and both the length of FH and the length of AG may represent a second numerical value in.
In addition, the background object can be identified according to the angle information of each position in the shot object relative to the first camera, namely, whether the included angle between the connecting line between each position and the first camera and the reference straight line is smaller than a preset angle threshold value or not is judged, and the part formed by the positions with the included angles larger than the preset angle threshold value is the background object; of course, the background object may also be identified separately according to the depth information of each position in the shot object, and a portion formed by positions of which the depth information is not within the preset range is the background object.
It should be noted that the background object may be identified by simultaneously combining the angle information of each position in the subject with respect to the first camera and the depth information of each position in the subject. For example: the partial image of the first image within the preset angle threshold range may be determined, and then a partial image of the partial image with the depth information within the preset range is determined as a target object, and an image of the first image other than the target object is determined as a background object.
After the background object in the first image is identified, the portion corresponding to the background object in the second image may be removed, so as to generate a target image including only the target object.
For example: the shot object comprises a face and a wall surface, the background object in the first image can be identified as the wall surface according to the depth information and/or the angle information in the first image, and the wall surface in the second image can be directly removed, so that a target image comprising the face only is generated.
In the embodiment of the present invention, the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In the embodiment of the invention, a first image of a shot object is acquired through the first camera, and a second image of the shot object is acquired through the second camera; acquiring depth information and/or angle information in the first image, and identifying a background object in the shot object according to the depth information and/or the angle information; and removing the background object included in the second image to generate a target image. Therefore, the background object can be directly identified through the depth information and/or the angle information in the first image, and then the background object in the second image is removed, so that the efficiency of removing the background object in the second image is improved.
Referring to fig. 3, fig. 3 is a flowchart of another image processing method according to an embodiment of the present invention. The main differences between this embodiment and the previous embodiment are: the preset range or the numerical value of the preset angle threshold value can be preset according to an operation instruction of a user. As shown in fig. 3, the method comprises the following steps:
and step 301, displaying a setting interface.
When the user opens the camera application program of the terminal and selects the background object removing mode, the setting interface can be directly displayed. Of course, when the user opens the camera application of the terminal and selects the background object removal mode, the setting interface may not be directly displayed, and when the display instruction input by the user is received, the setting interface is displayed. The specific manner is not limited herein.
The operation instruction of the user may be a pressing instruction, a touch instruction, a voice instruction, or the like, and the specific type is not limited herein.
Wherein, depth information and/or angle information can be set on the setting interface, for example: the depth information may include a range of depth information, i.e., a preset range, and the angle information may include a preset angle threshold. Of course, a pre-stored picture can also be directly acquired, and the depth information or the angle information of the picture can be modified.
For example: the line corresponding to the preset range and at least one of the lines corresponding to the preset angle threshold can be displayed on the setting interface, and a user can adjust the preset range or the preset angle threshold by dragging the line corresponding to the preset range or the line corresponding to the preset angle threshold.
In addition, when lines corresponding to the preset range and lines corresponding to the preset angle threshold are displayed on the setting interface at the same time, the lines of the two types can enclose a preset graph. Referring to fig. 4, A, E and G, the preset pattern in fig. 4 is defined by lines of two types AE and AG, and the specific type of the preset pattern is not limited herein, for example: the preset graph can be a cone, a pyramid or a hemisphere, and a user can drag a line in the preset graph, so that the purpose of setting a preset range or a preset angle threshold is achieved. In this way, the portion of the first image within the preset figure is the target object, and the portion of the first image not within the preset figure is the background object. So that the recognition rate of the background object can be improved.
In addition, the outlines of the target object and the background object in the first image can be marked, the first image and the second image are overlapped, and then the part of the background object in the second image is removed. Of course, it is also possible to store the depth information of the target object in the first image, superimpose the depth information of the target object and the color image information included in the second image, and find the contour formed by the depth information of the target object according to a convex hull algorithm (e.g., a Graham scan line algorithm, an Mlekman algorithm, etc.). And then, reserving pixel points corresponding to the color image information in the outline in the second image, and replacing pixel points corresponding to the color image information not in the outline with transparent pixel points, thereby achieving the purpose of eliminating the background object in the second image.
In addition, default numerical values of at least one of the preset range and the preset angle threshold value can be displayed on the setting interface, and a user can directly input the preset range or the setting numerical values of the preset angle threshold value.
It should be noted that the specific setting manner of the preset range and the preset angle threshold is not limited herein.
It should be noted that steps 301 and 302 are optional.
And 303, acquiring a first image of the object to be shot through the first camera, and acquiring a second image of the object to be shot through the second camera.
The shot object may include a background object and a target object, for example: the target object may be a human face and the background object may be a wall surface and a landscape painting hung on the wall surface.
The first image is an image in a video acquired by the first camera with respect to the subject, and the second image is an image in a video acquired by the second camera with respect to the subject.
In addition, the first image is an image in a video acquired by the first camera for the photographed object, and the second image is an image in a video acquired by the second camera for the photographed object, and the specific expression may refer to the expression in the previous embodiment, and the same beneficial technical effects in the previous embodiment may be achieved, which is not described herein again.
And the depth information in the first image is not in the preset range, and/or each position of which the angle information is larger than the preset angle threshold value forms a background object. For example: the preset range may be 1 meter to 10 meters, and the preset angle threshold may be 45 degrees.
It should be noted that the preset range may refer to a range between a value larger than the first value and a value smaller than the second value, where the value of the second value is related to the accuracy of the first camera, and the higher the accuracy of the first camera is, the higher the value of the second value is.
And directly deleting the pixel points of the background object in the second image.
Optionally, the removing the background object included in the second image to generate a target image includes:
identifying pixel points of the background object in the second image;
and setting pixel values corresponding to the pixel points of the background object in the second image as first pixel values, and generating the target image.
The first pixel value is smaller than the preset threshold, it should be noted that the pixel value may also be referred to as an RGB value, and the value of the preset threshold is not limited herein, for example: the preset threshold may be 0.1. Preferably, a pixel value corresponding to a pixel point of the background object in the second image may be set to 0, and the pixel point having the pixel value of 0 may be referred to as a transparent pixel point.
In this embodiment, the pixel value corresponding to the pixel point of the background object in the second image is set as the first pixel value, which can also achieve the effect of removing the background object, so that the step of removing the background object is simpler and more convenient, and the efficiency is higher.
Optionally, after setting pixel values corresponding to pixel points of the background object in the second image as first pixel values and generating the target image, the method further includes:
synthesizing a pixel point of a target object in the target image and depth information of the target object in the first image into a three-dimensional model of the target object, wherein the target object is an object except the background object in the shot object;
and running a virtual reality application program, and constructing a virtual reality application scene of the three-dimensional model through the virtual reality application program.
Therefore, by constructing the virtual reality application scene of the three-dimensional model, the application scene is more diversified and flexible.
Optionally, after setting pixel values corresponding to pixel points of the background object in the second image as first pixel values and generating the target image, the method further includes:
acquiring a third image comprising a scene to be synthesized;
and synthesizing the target image and the third image.
The scene to be synthesized may be a landscape image of a certain place or an image of a certain known person.
Therefore, the target image can be directly synthesized with the third image without using an image synthesis application program, the operation of a user is simplified, and the efficiency of image synthesis is improved.
In the embodiment of the present invention, through steps 301 to 305, a user may preset a corresponding preset range or a numerical value of a preset angle threshold according to a different usage scenario, so that flexibility of removing a background object may be improved.
