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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
At present, users often have a video call requirement, and the method is also a communication mode which is commonly used at present. Due to the portability of the smart phone, a user may use any angle and may continuously change the angle of the smart phone when using the smart phone to perform a video call, so that it is necessary to improve the experience of a video picture.
According to the scheme in the prior art, angle adjustment cannot be performed in the video call process, or even angle adjustment can be performed in the call process, a local mobile phone angle is sent to a receiving party through a message in the call process, and the receiving party performs rotary display on an image according to received information.
Therefore, in the embodiment of the invention, in the video call process, the angle information of the local and the receiving terminals is detected in real time, the currently acquired image is rotated, and the rotated image is sent to the receiving terminal, so that the local and the receiving terminals can display the rotated image in the current window of the video call, and thus, the image is continuously rotated according to the change of the angle of the sending terminal, the local image seen by the user at any angle and the sent video image can be ensured to be in an upright state, more accuracy is realized, and the image experience of the video call of the user is improved.
Of course, the embodiment of the present invention is not limited to a smart phone, and may also be applied to video call scenes of any other smart devices.
Referring to fig. 1, in the embodiment of the present invention, a specific flow of a video call processing method is as follows:
step 100: and in the video call process, acquiring the angle information of the current sending end.
Specifically, the angle information of the transmitting end can be detected in real time through the direction sensor.
In the embodiment of the present invention, mainly aiming at video picture display control of both video call parties, both video call parties may be either a receiver or a sender, and are relatively speaking, for example, both video call parties include a first terminal and a second terminal, the first terminal may send a currently acquired image to the second terminal, at this time, the first terminal is a sender, the second terminal is a receiver, and at the same time, the first terminal may also receive an image acquired by the second terminal, at this time, the first terminal is a receiver, and the second terminal is a sender.
The sending end and the receiving end can be intelligent terminals, such as smart phones.
Further, before step 100 is executed, in the embodiment of the present invention, a video call may be established according to the video call instruction, and the image acquisition device starts to acquire the image of the video based on the preset image acquisition angle.
The image capturing device is, for example, a camera, and the embodiment of the present invention is not limited thereto.
That is to say, in the embodiment of the present invention, image acquisition is performed through the camera always based on the preset image acquisition angle, and after the video call is established, the angle information is detected in real time through the direction sensor.
Step 110: and rotating the currently acquired image according to the angle information and a preset image acquisition angle.
When step 110 is executed, the method specifically includes:
1) and judging whether the angle information is the same as the preset image acquisition angle.
Further, in the embodiment of the present invention, after the angle information of the current sending end is obtained, in order to improve efficiency and accuracy, the image does not need to be rotated every time the angle of the sending end is changed, and specifically, a possible implementation manner is provided, in which the angle information of the current sending end is classified into a preset angle value according to a preset angle interval, and whether the classified angle information is the same as a preset image acquisition angle is determined according to the classified angle information.
For example, the preset angle values are 0 degree, 90 degrees, 180 degrees and 270 degrees, for example, the angle interval (45, 90) is normalized to 90 degrees, and the angle interval (0, 45) is normalized to 0 degree, and if it is determined that the angle of the current receiving end is 30 degrees, the angle is considered to be 0 degree.
Therefore, the image can not be rotated due to the small angle change of the sending end, certain errors can be allowed, the experience of the video picture of the user can not be influenced, and the calculation amount is reduced.
2) And if the angle information is different from the preset image acquisition angle, determining the difference value between the angle information and the preset image acquisition angle.
In the embodiment of the invention, the image acquisition angle of the camera is always unchanged, for example, 0 degree, and is upright for vertical screen, if the user changes the angle of the transmitting end, for example, to upright for horizontal screen, at this time, the angle of the transmitting end can be determined to be 90 degrees, but the image is acquired based on 0 degree, at this time, the angle of the acquired image is not matched with the angle of the transmitting end, so that the angle change value of the transmitting end needs to be determined, and the direction and the angle of the acquired image are adjusted.
3) Based on a Graphics Processing Unit (GPU), the currently acquired image is rotated according to the difference.
Therefore, the image is rotated by the GPU, the image is also rotated by the angle value changed by the sending end, the image can be in an upright state, and the image is rotated based on the GPU, so that the processing efficiency is higher.
Further, if the determination is different, that is, it is determined that the angle of the transmitting end changes, the embodiment of the present invention further includes pausing video encoding, and reconfiguring an encoder according to the difference value, so that the encoded transmission of the rotated image is performed.
Step 120: and displaying the rotated image, and sending the rotated image to a receiving end so that the receiving end displays the rotated image.
When the step 120 is executed, the method specifically includes:
1) displaying the rotated image, specifically comprising:
determining the width-height ratio of a display window and the width-height ratio of the rotated image; and judging whether the width-height ratio of the display window and the width-height ratio of the rotated image are not more than or not less than a preset threshold value, if so, displaying the rotated image on the display window in a full screen mode, otherwise, displaying all the rotated images at preset positions on the display window according to the width-height ratio of the rotated image.
The preset threshold is, for example, 1, and the embodiment of the present invention is not limited, and may be set according to actual situations and requirements.
In the embodiment of the invention, when an image is displayed, the width-height ratio of a display window and the width-height ratio of the image are compared, so that the display mode is determined, if neither of the two is greater than or less than 1, the width-height relationship of the image and the width-height relationship of the display window are the same, full-screen display can be performed at this time, the display effect of the rotated image is not influenced, if one of the two is less than 1, and the other is greater than 1, the width-height relationship of the two is opposite, if full-screen display is performed on the display window, the image is cut too much and displayed incompletely, therefore, the rotated image can be displayed at a preset position of the display window, such as the middle position, according to the width-height ratio of the rotated image, so that the image is not stretched, the width-height ratio is ensured to be unchanged, the image is not deformed, and the display effect is not influenced, and also to ensure a complete display of the image.
2) And sending the rotated image to a receiving end so that the receiving end displays the rotated image.
The method specifically comprises the following steps: and coding the rotated image according to a preset coding algorithm, and sending the coded image to a receiving end.
The preset encoding algorithm is, for example, an H264 encoding algorithm, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, when the receiving end displays the rotated image, the receiving end displays the image according to the width-height ratio of the display window and the width-height ratio of the rotated image. That is, the receiving end also compares the width-height ratio of the display window with the width-height ratio of the rotated image to determine the display mode, which is specifically the same as the method for determining the display mode of the transmitting end.
Therefore, in the embodiment of the invention, in the video call process, the angle information of the current sending end is detected in real time, and the current collected image is rotated according to the angle information and the preset image collecting angle; the image after rotation is displayed and sent to the receiving end, so that the receiving end displays the image after rotation, the image is rotated according to the change of angle information of the receiving end, the image after rotation is displayed locally and is sent to the receiving end after being coded by the coder, and therefore the video image displayed locally and the video image displayed by the receiving end are both upright normal images, different mobile phone holding modes of users are met, the conversation visual field of the users is expanded, the purpose of free screen rotation in the video conversation process is achieved, image rotation is carried out through a GPU of the receiving end, the processing efficiency is high, excessive CPU resources are not consumed, real-time synchronism can be guaranteed, and the accuracy of the image rotation is improved.

When the local display is carried out, the sending end compares the width-height ratio of the display window with the width-height ratio of the rotated image to determine the display mode.
