It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
FIG. 1 is a flow diagram illustrating an image processing method according to an exemplary embodiment. The image processing method can be applied to electronic equipment, and here, the electronic equipment can be a notebook computer, a desktop computer, a palm computer, a mobile phone, a netbook, a personal digital assistant, or the like.
As shown in fig. 1, the image processing method may include the steps of:
in step S11, an original image captured by a camera is acquired, and a rotation angle of the camera is acquired.
In this embodiment, the camera device may be a camera, or may be a device equipped with a camera. The camera device may be connected to an interface of the electronic device through a data line, or may be connected to the electronic device through a wireless communication module.
The original image may be a landscape screen image or a portrait screen image. Here, the landscape image may be an image having a length greater than a width, for example, an image having an aspect ratio of 16:9, an image having an aspect ratio of 3:2, or an image having an aspect ratio of 4: 3; the portrait screen image may be an image having a length less than a width, for example, an image having an aspect ratio of 9:16, an image having an aspect ratio of 2:3, or an image having an aspect ratio of 3: 4.
The original image acquired by the image capturing device may be an original image acquired by a real-time image capturing device.
The above-mentioned obtaining the rotation angle of the camera device may be obtaining the rotation angle of the camera device in real time; the rotation angle of the imaging device may be acquired when the imaging device is rotated. It should be noted that, if the above-mentioned obtaining of the rotation angle of the image capturing apparatus is obtaining of the rotation angle of the image capturing apparatus when the image capturing apparatus rotates, during the period from the nth (N is a positive integer) time of rotating the image capturing apparatus to the (N + 1) th time of rotating the image capturing apparatus, the rotation angles corresponding to all the original images collected by the image capturing apparatus may all be the rotation angle during the nth time of rotating the image capturing apparatus, and similarly, during the period from the (N + 1) th time of rotating the image capturing apparatus to the (N + 2) th time of rotating the image capturing apparatus, the rotation angles corresponding to all the original images collected by the image capturing apparatus may all be the rotation angles during the (N + 1) th time.
The rotation angle can be used for indicating the rotation angle of the placing posture of the camera device when the original image is collected relative to the standard placing posture. Here, the standard placement posture may refer to a placement posture when the camera device is used conventionally, that is, the standard placement posture may refer to a placement posture when an original image acquired by the camera device is an erected image.
In step S12, when the rotation angle is within a first preset angle range, the original image is rotated according to the rotation angle to obtain a target image.
In this embodiment, the first preset angle range may include one or more angle ranges.
Specifically, in order to make the switching between the horizontal and vertical screens more sensitive and improve the convenience of the user operation, optionally, the first preset angle range may include at least one of the following: clockwise 90 degrees +/-A, clockwise 180 degrees +/-A, clockwise 270 degrees +/-A, anticlockwise 90 degrees +/-A, anticlockwise 180 degrees +/-A and anticlockwise 270 degrees +/-A; the A is greater than or equal to 0 degrees and less than 45 degrees. Here, 90 degrees ± a clockwise may represent greater than or equal to 90-a degrees clockwise and less than or equal to 90+ a degrees clockwise; 180 degrees ± a clockwise may represent greater than or equal to 180-a degrees clockwise and less than or equal to 180+ a degrees clockwise; clockwise 270 degrees ± a may represent greater than or equal to 270-a degrees clockwise and less than or equal to 270+ a degrees clockwise; 90 degrees counterclockwise ± a may represent greater than or equal to 90-a degrees counterclockwise and less than or equal to 90+ a degrees counterclockwise; 180 degrees counterclockwise ± a may represent greater than or equal to 180-a degrees counterclockwise and less than or equal to 180+ a degrees counterclockwise; counterclockwise 270 degrees ± a may represent greater than or equal to counterclockwise 270-a degrees and less than or equal to counterclockwise 270+ a degrees.
The above rotation angle in the first preset angle range can be understood as: the rotation angle belongs to a first preset angle range. For ease of understanding, further exemplified herein:
assuming that the first preset angle range includes 4 angle ranges, the 4 angle ranges are [ 60 degrees clockwise, 120 degrees clockwise ], [ 240 degrees clockwise, 300 degrees clockwise ], [ 60 degrees counterclockwise, 120 degrees counterclockwise ] and [ 240 degrees counterclockwise, 300 degrees counterclockwise ], where [ 60 degrees clockwise, 120 degrees clockwise ] represents greater than or equal to 60 degrees clockwise and less than or equal to 120 degrees clockwise, [ 240 degrees clockwise, 300 degrees clockwise ] represents greater than or equal to 240 degrees clockwise and less than or equal to 300 degrees clockwise, [ 60 degrees counterclockwise, 120 degrees counterclockwise ] represents greater than or equal to 60 degrees counterclockwise and less than or equal to 120 degrees counterclockwise, [ 240 degrees counterclockwise, 300 degrees counterclockwise ] represents greater than or equal to 240 degrees counterclockwise and less than or equal to 300 degrees counterclockwise, respectively;
then, when the rotation angle is 90 degrees clockwise, the rotation angle can be considered to be in an angle range of [ 60 degrees clockwise, 120 degrees clockwise ], and further the rotation angle can be considered to be in a first preset angle range; when the rotation angle is 270 degrees clockwise, the rotation angle can be considered to be in the angle range of [ 240 degrees clockwise and 300 degrees clockwise ], and further the rotation angle can be considered to be in the first preset angle range; when the rotation angle is 90 degrees counterclockwise, the rotation angle can be considered to be in an angle range of [ 60 degrees counterclockwise and 120 degrees counterclockwise ], and further the rotation angle can be considered to be in a first preset angle range; when the rotation angle is 270 degrees counterclockwise, the rotation angle may be considered to be in an angle range of [ 240 degrees counterclockwise, 300 degrees counterclockwise ], and further the rotation angle may be considered to be in a first preset angle range.
Rotating the original image to obtain a target image, wherein the target image can be obtained by performing horizontal-vertical conversion on the original image; the original image is rotated to obtain the target image, or the original image is rotated by 180 degrees to obtain the target image. Here, horizontal-vertical conversion may be understood as horizontal screen to vertical screen or vertical screen to horizontal screen.
In step S13, the target image is encoded, and the encoded target image is pushed to a server.
In this embodiment, the target image may be encoded according to a preset encoding resolution, or the target image may be encoded according to an adjusted encoding resolution by adjusting the preset encoding resolution.
In this embodiment, by acquiring an original image acquired by a camera device and acquiring a rotation angle of the camera device, when the rotation angle is within a first preset angle range, the original image is rotated according to the rotation angle to obtain a target image, the target image is encoded, and the encoded target image is pushed to a server, so that the live image can be automatically rotated according to the rotation angle of the camera device, and the live image after the rotation processing can be automatically pushed, so that a user performing network live broadcasting can rotate the live image by rotating the camera device in the live broadcasting process without importing the live image into a third-party application program and then executing a series of operations on an application interface of the third-party application program, and therefore, the operation of the live image during the rotation processing can be simpler in the embodiment of the present disclosure, and the efficiency of rotating the live image can be improved.
Optionally, after the acquiring an original image acquired by the camera device and the acquiring a rotation angle of the camera device, the image processing method further includes:
and when the rotation angle is not in the first preset angle range, encoding the original image, and pushing the encoded original image to the server.
In this embodiment, when the rotation angle of the imaging device is not within the first preset angle range, the original image may be directly encoded without performing rotation processing on the original image, and the encoded original image may be pushed to the server.
The fact that the rotation angle is not within the first preset angle range can be understood as follows: the rotation angle does not belong to the first preset angle range. For ease of understanding, further exemplified herein:
assuming that the first preset angle range set includes 4 angle ranges, the 4 angle ranges are [ 60 degrees clockwise, 120 degrees clockwise ], [ 240 degrees clockwise, 300 degrees clockwise ], [ 60 degrees counterclockwise, 120 degrees counterclockwise ], [ 240 degrees counterclockwise, 300 degrees counterclockwise ], where [ 60 degrees clockwise, [ 120 degrees clockwise ] represents greater than or equal to 60 degrees clockwise and less than or equal to 120 degrees clockwise, [ 240 degrees clockwise, 300 degrees clockwise ] represents greater than or equal to 240 degrees clockwise and less than or equal to 300 degrees clockwise, [ 60 degrees counterclockwise, 120 degrees counterclockwise ] represents greater than or equal to 60 degrees counterclockwise and less than or equal to 120 degrees counterclockwise, [ 240 degrees counterclockwise, 300 degrees counterclockwise ] represents greater than or equal to 240 degrees counterclockwise and less than or equal to 300 degrees counterclockwise;
when the rotation angle is 0 degrees clockwise or 180 degrees clockwise, the rotation angle may not be considered to be in any one of the 4 angular ranges, and further, the rotation angle may not be considered to be in the first preset angular range.
The encoding of the original image may be encoding the original image according to a preset encoding resolution, or adjusting the preset encoding resolution and encoding the original image according to the adjusted encoding resolution.
Because when the rotation angle is not in during the first predetermined angle scope, can be directly right the original image is encoded, and to after the server propelling movement is encoded original image to when need not rotating the live broadcast image, the user only need control the rotation angle not in first predetermined angle scope can, that is to say, make this application embodiment can also be applicable to the scene that need not to rotate the live broadcast image, like this, can make the suitability of this embodiment stronger.
Optionally, the encoding the target image includes:
and when the rotation angle is within a second preset angle range, adjusting a preset encoding resolution, and encoding the target image according to the adjusted encoding resolution, wherein the first preset angle range comprises the second preset angle range.
In this embodiment, when the rotation angle is within the first preset angle range and within the second preset angle range, the preset encoding resolution may be adjusted first, and the target image may be encoded according to the adjusted encoding resolution.
The second preset angle range may include at least one of: clockwise 90 degrees +/-A, clockwise 270 degrees +/-A, anticlockwise 90 degrees +/-A and anticlockwise 270 degrees +/-A; the A is greater than or equal to 0 degrees and less than 45 degrees. Here, for the explanation of clockwise 90 degrees ± a, clockwise 270 degrees ± a, counterclockwise 90 degrees ± a and counterclockwise 270 degrees ± a, reference may be made to the explanation of the relevant parts in the foregoing, and thus, the explanation is not repeated here.
The preset encoding resolution may be a horizontal screen resolution adapted to the horizontal screen image or a vertical screen resolution adapted to the vertical screen image, that is, the default encoding resolution may be the horizontal screen resolution or the vertical screen resolution. Specifically, the vertical screen resolution may be set as required, for example, may be set to 768x 1024, 1080x 1920, 2160x 3840, or the like; the foregoing horizontal screen resolution may also be set as required, for example, 1024x 768, 1920x 1080 or 3840x 2160, etc. Under the condition that the target image is a cross-screen image, if the cross-screen resolution is adopted to code the target image, the definition of a picture seen by a user watching live broadcast can be higher; under the condition that the target image is a vertical screen image, if the target image is coded by adopting the vertical screen resolution, the definition of a picture seen by a user watching live broadcast can be higher.
The adjusted encoding resolution may be a resolution different from a preset encoding resolution. For example, when the preset encoding resolution is a horizontal screen resolution, the adjusted encoding resolution may be a vertical screen resolution; when the preset encoding resolution is the vertical screen resolution, the adjusted encoding resolution may be the horizontal screen resolution.
Because when the rotation angle is in the second predetermined angle scope, the adjustment is preset's coding resolution ratio, and is right according to the coding resolution ratio after the adjustment target image encodes, first predetermined angle scope includes the second predetermined angle scope to not only can be according to camera device's rotation angle, automatic rotation processing is carried out to the live broadcast image, but also can be according to camera device's rotation angle, the resolution ratio of self-adaptation output image, like this, not only can make the live broadcast user in the live broadcast in-process, can realize the rotation processing to the live broadcast image through rotating camera device at any time, and can improve spectator's end's picture definition.
Optionally, the encoding the target image includes:
and when the rotation angle is not in a second preset angle range, coding the target image according to a preset coding resolution.
In this embodiment, whether the rotation angle is in the first preset angle range or not, as long as the rotation angle is not in the second preset angle range, the target image may be directly encoded according to a preset encoding resolution.
When the rotation angle is not within the second preset angle range, the target image is coded according to the preset coding resolution, so that the live broadcast image can be automatically rotated according to the rotation angle of the camera device, the resolution of the image can be adaptively output according to the rotation angle of the camera device, a live broadcast user can rotate the live broadcast image at any time in the live broadcast process by rotating the camera device, and the image definition of a viewer end can be improved.
Optionally, when the rotation angle is within a first preset angle range, rotating the original image according to the rotation angle to obtain a target image, including:
when the rotation angle is clockwise 90 degrees +/-A, clockwise 270 degrees +/-A, anticlockwise 90 degrees +/-A or anticlockwise 270 degrees +/-A, performing horizontal-vertical conversion on the original image through rotation to obtain a target image;
and when the rotation angle is 180 degrees +/-A clockwise or 180 degrees +/-A anticlockwise, rotating the original image by 180 degrees to obtain a target image.
In this embodiment, it can be considered that the placement posture of the imaging device when the rotation angle is 90 degrees clockwise is the same as the placement posture of the imaging device when the rotation angle is 270 degrees counterclockwise, and the placement posture of the imaging device when the rotation angle is 270 degrees clockwise is the same as the placement posture of the imaging device when the rotation angle is 90 degrees counterclockwise. It is considered that the image pickup apparatus arrangement posture when the rotation angle is 180 degrees clockwise is the same as the image pickup apparatus arrangement posture when the rotation angle is 180 degrees counterclockwise.
The horizontal-vertical conversion may refer to converting a landscape screen image into a portrait screen image or converting a portrait screen image into a landscape screen image. Specifically, when the original image is a landscape image, the above-mentioned obtaining the target image by performing horizontal-vertical conversion on the original image through rotation may be understood as: and rotating the original image into a vertical screen image, and determining the vertical screen image as a target image. In the case that the original image is a vertical screen image, the above-mentioned obtaining of the target image by performing horizontal-vertical conversion on the original image through rotation may be understood as: the original image is rotated into a landscape image, and the landscape image is determined as a target image.
It should be noted that, after the original image is rotated by 180 degrees, the horizontal and vertical directions of the original image will not change, but the forward and backward directions of the original image will change, that is, if the original image is an upright landscape screen image, the target image obtained after the original image is rotated by 180 degrees is an inverted landscape screen image; if the original image is an inverted cross-screen image, rotating the original image by 180 degrees to obtain a target image which is an upright cross-screen image; if the original image is an upright vertical screen image, rotating the original image by 180 degrees to obtain a target image which is an inverted vertical screen image; and if the original image is an inverted vertical screen image, rotating the original image by 180 degrees to obtain a target image which is an upright vertical screen image.
Because the original image is converted horizontally and vertically through rotation when the rotation angle is 90 degrees +/-A clockwise, 270 degrees +/-A clockwise, 90 degrees +/-A counterclockwise or 270 degrees +/-A counterclockwise to obtain the target image, and the original image is rotated 180 degrees to obtain the target image when the rotation angle is 180 degrees +/-A clockwise or 180 degrees +/-A counterclockwise, the automatic conversion of horizontal and vertical screens can be realized, and the target image output to the streaming media server can be ensured to be a vertical image, so that the user at a viewer end can watch the target image more conveniently.
Optionally, when the rotation angle is clockwise 90 degrees ± a, clockwise 270 degrees ± a, counterclockwise 90 degrees ± a, or counterclockwise 270 degrees ± a, performing horizontal-vertical conversion on the original image through rotation to obtain a target image, including:
when the rotation angle is 90 degrees clockwise, rotating the original image 90 degrees clockwise or 270 degrees anticlockwise to obtain a target image;
when the rotation angle is 270 degrees clockwise, rotating the original image 270 degrees clockwise or rotating the original image 90 degrees counterclockwise to obtain a target image;
when the rotation angle is 90 degrees anticlockwise, rotating the original image 90 degrees anticlockwise or 270 degrees clockwise to obtain a target image;
