Referring to fig. 2, in an embodiment of a stereoscopic image processing method, the stereoscopic image processing method includes:
step S10, when detecting the intercepting instruction aiming at the stereo image, the terminal obtains the odd frame picture and the even frame picture in the stereo image according to the intercepting instruction;
in this embodiment, the stereoscopic image is a three-dimensional stereoscopic image that can be seen by the user in one plane by using the principle of binocular vision difference and optical refraction of the user. In addition, the terminal (e.g., a smart television, a computer, etc.) in this embodiment needs to detect whether the terminal has a switch function of the stereoscopic glasses (a device for allowing a user to view a stereoscopic image), and determine whether the switch of the stereoscopic glasses is turned on, and the turn-on time is longer than 1 minute, and if so, the subsequent stereoscopic image capturing operation may be performed. Or whether the terminal system has the function of opening and closing the stereo image is detected, that is, whether the terminal supports the playing of the stereo image is detected, and only when the terminal supports the playing of the stereo image, the subsequent operation of intercepting the stereo image can be carried out. When the terminal plays the stereo video decoding, after receiving an instruction of intercepting a video program, namely an instruction of intercepting a stereo image in the terminal, the terminal can start to intercept the stereo image according to the interception instruction. When an intercepting instruction is received, user information (such as a name, a family identity and the like) corresponding to the intercepting instruction needs to be acquired first, so that whether the user has specific authority to perform intercepting operation or not is detected. The manner of acquiring the user information may be acquiring when the user inputs the user information through a remote controller or other terminals, or performing fingerprint identification when the user picks up a terminal such as a remote controller, and determining the user information based on the fingerprint identification result. It should be noted that the clipping instruction may include the length of the stereoscopic image to be clipped, for example, 60 seconds, and further include a source of the stereoscopic image, for example, determining whether the source is a shutter or a polarization.
After the capturing instruction is obtained, the terminal can capture the stereoscopic image according to the capturing instruction, and in the process of capturing the stereoscopic image video frame program, the stereoscopic image video stream which is being played in the terminal is read, and a first buffer area, namely a first buffer area, is arranged in the terminal so as to temporarily store two read frame images of the stereoscopic image, namely an odd frame image and an even frame image. It should be noted that, in this embodiment, the stereoscopic image is played in the terminal in a video stream manner, that is, each frame has a certain playing sequence. And continuously acquiring new odd frame images and even frame images in the first buffer area according to the playing sequence of the stereo images, namely continuously updating the odd frame images and the even frame images in the first buffer area. As shown in fig. 4, the video buffering acquisition module stores a first storage space, i.e., stores the acquired odd frame pictures and even frame pictures in the first storage space (storage area one). The odd frame picture may be a picture of an odd frame acquired when performing a capture operation, such as a first frame picture, a third frame picture, and the like. The even frame picture may be a picture of an even frame acquired when the clipping operation is performed, such as a second frame picture, a fourth frame picture, or the like.
Step 20, the terminal extracts odd pixel information in the odd frame picture and even pixel information in the even frame picture to obtain first pixel information, and extracts even pixel information in the odd frame picture and odd pixel information in the even frame picture to obtain second pixel information;
after the terminal acquires the odd frame picture and the even frame picture, a second buffer area (i.e., a second video left-eye data processing storage space) and a third buffer area (i.e., a third video right-eye data processing storage space) as shown in fig. 5 may be set again, that is, corresponding processing is performed on the odd frame picture and the even frame picture in the first buffer area, odd lines and even lines of the odd frame picture and even lines of the even frame are determined, odd pixel information of the odd lines and even pixel information of the even lines of the even frame are extracted from the odd frame picture, and the odd pixel information of the odd lines and the even pixel information of the even lines of the even frame are stored in the second buffer area as first pixel information. And extracting even pixel information of even lines of the odd frame picture and odd pixel information of odd lines of the even frame picture, and storing the even pixel information of the even lines of the odd frame picture and the odd pixel information of the odd lines of the even frame picture as second pixel information in a third buffer area. For example, when the odd frame picture is the first frame picture, the even frame picture is the second frame picture, and the pixel point in each row of each frame picture is 1280, then 1280/2 is calculated to be 640, at this time, the 0-630 pixel points in the first row of the first frame picture can be stored in the second buffer as the odd pixel information of the first frame picture, and the 640-1280 pixel points in the second row of the second frame picture can be stored in the second buffer as the even pixel information of the second frame picture. And storing the 0-630 pixel points in the second row of the first frame image as the even pixel information of the first frame image in the third buffer area, and storing the 640-1280 pixel points in the first row of the second frame image as the odd pixel information of the second frame image in the third buffer area. The odd-numbered pixel information may be half of the pixels in the odd-numbered lines of each frame. The even pixel information may be half of the pixels in the even rows of each frame. The first pixel information may be a pixel point stored in the storage area two. The second pixel information may be a pixel point stored in the storage area three.
Step S30, the terminal determines a left glasses and a right glasses corresponding to the stereo image, transmits the first pixel information to the left glasses, and transmits the second pixel information to the right glasses;
in this embodiment, a fourth storage area is also created for storing left glasses (i.e., left glasses part) and right glasses (i.e., right glasses part), that is, stereoscopic glasses corresponding to the terminal where the stereoscopic image is located need to be determined first, the stereoscopic glasses establish a communication connection with the terminal, and the left glasses and the right glasses in the stereoscopic glasses are determined. And then respectively starting the left glasses and the right glasses according to the second buffer area and the third buffer area, namely starting a left glasses switch when detecting that the odd pixel information in the odd frame picture is received in the second buffer area, transmitting the odd pixel information in the odd frame picture to the left glasses, closing the left glasses when the even pixel information in the odd frame picture is received in the third buffer area, starting a right glasses switch, and transmitting the even pixel information in the odd frame picture to the right glasses. And when the buffer area III receives the odd pixel information in the even frame picture, the left glasses are closed, the right glasses switch is started, and the odd pixel information in the even frame picture is transmitted to the right glasses. And when the even pixel information in the even frame picture is received in the second buffer area, starting a switch of the left glasses, closing the right glasses, and transmitting the even pixel information in the even frame picture to the left glasses. Namely, an interlaced pixel processing mode is adopted, and when the terminal system processes pixels and sends the pixels to the display panel for display, information for controlling glasses is sent to the stereo glasses, so that the left end and the right end in the stereo glasses are dynamically switched, and a user can visually see a stereo image. And as shown in fig. 6, the video left and right glasses switching data processing storage space is four, that is, the data of the left glasses and the data of the right glasses are stored in the storage space four, and different activation time and closing time of the left and right glasses are set according to different odd and even pixels, for example, the left glasses are activated for 50ms when detecting odd pixel information in an odd frame picture, are deactivated for 45ms when detecting even pixel information in an odd frame picture, are deactivated for 45ms when detecting odd pixel information in an even frame picture, and are activated for 50ms when detecting even pixel information in an even frame picture.
In step S40, if the clipping stop instruction for the stereoscopic image is received, the terminal generates a clipped stereoscopic image according to the first pixel information stored in the left glasses and the second pixel information stored in the right glasses, and outputs the clipped stereoscopic image.
When an interception stop instruction corresponding to the interception instruction is received in the terminal, the terminal can stop the interception operation of the stereoscopic image according to the interception stop instruction. And forming an intercepted three-dimensional image according to the first pixel information acquired by the left glasses and the second pixel information acquired by the right glasses, namely determining the playing sequence of the first pixel information and the second pixel information according to the starting time of the left glasses and the starting time of the right glasses, arranging the first pixel information and the second quadrant information according to the playing sequence to obtain the intercepted three-dimensional image, and outputting the intercepted three-dimensional image, such as displaying on a display interface sent to a terminal and the like.
In addition, in order to assist understanding of the present embodiment, in order to assist understanding of the stereoscopic image capturing, an example is described below.
For example, if a stereoscopic image capture needs to be performed on a stereoscopic image video stream of 1280x720@60Hz, when a user presses a stereoscopic video capture key and the terminal receives a capture instruction, the user information obtained by the terminal according to the capture instruction is: mom, time 60s of capture, the current video (i.e., stereo image) film source is the shutter release. And performing stereo image interception according to an interception instruction, namely creating a second buffer area and a third buffer area, wherein because the pixel point of each frame picture is 1280, 1280/2 can be calculated as 640, 0-639 of the first row in the first frame picture is stored in the second buffer area as an odd pixel point (namely, odd pixel information of the odd frame picture), 640-1280 of the second row in the second frame picture is stored in the second buffer area as even pixel information of the second frame picture, 0-639 of the second row in the first frame picture is stored in the third buffer area as an even pixel point (namely, even pixel information of the odd frame picture), and 640-1280 of the first row in the second frame picture is stored in the third buffer area as odd pixel information of the second frame picture. And the odd frame picture (such as a first frame picture) and the even frame picture (such as a second frame picture) are subjected to different pixel point acquisition aiming at different lines in the same mode so as to achieve the phenomenon of video pixel interlacing. And a fourth buffer area is created to store the left glasses and the right glasses, namely, the left glasses are opened for 50ms when the pixels in the first row of the first frame picture are 0-640, and the left glasses are closed for 45ms when the pixels in the first row of the first frame picture are 640-1280. And when the pixels in the second frame are 0-640, closing the left glasses for 45ms, and when the pixels in the second frame are 640-1280, opening the left glasses for 50 ms. And when receiving the interception stop instruction, stopping intercepting the three-dimensional image and outputting the successfully intercepted three-dimensional image.
In the present embodiment, by acquiring the odd frame picture and the even frame picture of the stereoscopic image according to the clipping instruction, and transmits the odd pixel information in the odd frame picture and the even pixel information of the even frame picture as first pixel information to the left glasses, transmits the even pixel information in the odd frame picture and the odd pixel information of the even frame picture as second pixel information to the right glasses, thereby leading the intercepted three-dimensional image to generate the phenomenon of video pixel interlacing, ensuring the three-dimensional effect of the intercepted three-dimensional image, and when receiving the interception stop instruction, forming a cut stereoscopic image according to the first pixel information acquired by the left glasses and the second pixel information acquired by the right glasses, and outputting the cut stereoscopic image, therefore, the phenomenon that an additional device is needed to record the three-dimensional image in the prior art is avoided, and the efficiency and the accuracy of capturing the three-dimensional image video are improved.
Further, on the basis of the first embodiment of the present invention, there is further provided a second embodiment of the stereoscopic image processing method of the present invention, which is step S20 of the first embodiment of the present invention, and the refinement of the step of extracting odd-numbered pixel information in an odd-numbered frame picture and even-numbered pixel information in an even-numbered frame picture by the terminal to obtain the first pixel information includes:
step a, the terminal extracts odd pixel information of odd lines in an odd frame picture and even pixel information of even lines in an even frame picture, and the odd pixel information of the odd lines in the odd frame picture and the even pixel information of the even lines in the even frame picture are first pixel information.
In this embodiment, after the terminal determines the odd frame picture and the even frame picture, it needs to set the second buffer area, determine the odd rows in the odd frame picture, and extract the odd pixel information of the odd rows, for example, using the first row 0-630 pixels of the first frame picture as the odd pixel information of the odd rows in the odd frame picture. Similarly, the even-numbered lines in the even-numbered frame picture need to be determined, and the even-numbered pixel information of the even-numbered lines needs to be extracted, for example, the second line 640-1280 pixel points of the second frame picture are used as the even-numbered pixel information of the even-numbered lines in the even-numbered frame picture. And the odd pixel information of the odd lines in the odd frame picture and the even pixel information of the even lines in the even frame picture are stored as the first pixel information in the second buffer area.
In this embodiment, the terminal extracts odd pixel information of an odd line in an odd frame picture and even pixel information of an even line in an even frame picture as the first pixel information, thereby ensuring the accuracy of the acquired first pixel information.

In this embodiment, after the terminal determines the odd frame picture and the even frame picture, it needs to set the third buffer area, determine the even rows in the odd frame picture, and extract the odd pixel information of the even rows, for example, using the second row 0-630 pixel points of the first frame picture as the odd pixel information of the even rows in the odd frame picture. Similarly, the odd-numbered lines in the even-numbered frame are determined, and the odd-numbered pixel information of the odd-numbered lines is extracted, for example, the first line 640-1280 pixel points of the second frame are used as the even-numbered pixel information of the even-numbered lines in the even-numbered frame. And the even pixel information of the even lines in the odd frame picture and the odd pixel information of the odd lines in the even frame picture are stored in the third buffer area as the second pixel information.
In this embodiment, the accuracy of the acquired second pixel information is ensured by extracting the even pixel information of the even line in the odd frame picture and the odd pixel information of the odd line in the even frame picture as the second pixel information.
Further, the step of the terminal transferring the first pixel information to the left glasses includes:
c, the terminal determines the starting time of the left glasses according to the first pixel information and determines the closing time of the left glasses according to the second pixel information;
and step x, transmitting the first pixel information to the left glasses according to the starting time and the closing time of the left glasses.
In this embodiment, when the second buffer has stored the first pixel information and the third buffer has stored the second pixel information, the terminal may determine a time node of a start time of the left glasses according to the first pixel information and determine a time node of a stop time of the left glasses according to the second pixel information, so that when the input first pixel information is detected in the second buffer, the terminal may start the left glasses (i.e., the left glasses) and continue to be started for 50ms, acquire the first pixel information through the left glasses and store the first pixel information in the preset fourth buffer, and when the input second pixel information is detected in the third buffer, the terminal may stop the left glasses for 45 ms. For example, when the pixels in the first row of the first frame are 0-640, the left glasses are turned on for 50ms, and when the pixels are 640-1280, the left glasses are turned off for 45 ms. And when the pixels in the second frame are 0-640, closing the left glasses for 45ms, and when the pixels in the second frame are 640-1280, opening the left glasses for 50 ms.
In the present embodiment, by determining the start-up time of the left glasses according to the first pixel information, determining the close time of the left glasses according to the second pixel information, and transferring the first pixel information to the left glasses based on the two times, stable transmission of the first pixel information is ensured.
