In this embodiment, a method for recording a video running on the mobile terminal is provided, and fig. 2 is a flowchart for recording a video according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring N first videos acquired by N image acquisition devices, wherein N is a positive integer greater than 1, and the N first videos are obtained by respectively shooting the same target object by the N image acquisition devices at different shooting angles;
wherein, the video interface of N image acquisition device includes: VGA, DVI, HDMI, SDI, DP, etc. The first videos acquired by the N image acquisition devices may be: operation panoramic video, endoscope video, ultrasonic video, operation field video, electrocardiogram video and the like. The video quality collected by different image collection devices is generally different, and the video quality mainly includes pixels, video frame rate, and the like, for example, a pixel point of a video may be D1720 × 576; 720P 1280 × 720; 1080p 1920 × 1080, etc., the video frame rate can be 25F \ s, 30F \ s, 50F \ s, 60F \ s, etc.
Step S204, determining a first target frame rate according to the frame rate of each video in the N first videos, and recording the N first videos according to the first target frame rate to obtain the first target video, wherein the first target video comprises the N first videos.
Determining a first target frame rate according to each frame rate of the N first videos, wherein the first target frame rate may be determined in various manners, for example, determining a minimum frame rate of the N first videos as the first target frame rate; or, determining the maximum frame rate in the N first videos as the first target frame rate; or, selecting a frame rate meeting a predetermined condition from the N first videos as the first target frame rate. The frame rates of the N first videos may all be the same, may all be different, and may also be partially the same. Taking the endoscope video, the ultrasonic video and the surgical field video which are respectively collected by the endoscope video collecting device, the ultrasonic video collecting device and the surgical field video collecting device in the same operation as an example, the frame rate of the endoscope video is 5F \ S, the frame rate of the ultrasonic video is 10F/S and the frame rate of the surgical field video is 25F/S. The first target frame rate may be a minimum frame rate of 5F \ S, a maximum frame rate of 25F/S, an intermediate frame rate of 10F/S, or an average of the minimum frame rate and the maximum frame rate of 15F/S, or an average of the three frame rates, where if the average is a decimal, an integer is taken according to a rounding principle. And recording the N first videos into one video, wherein the frame rate of the video is the first target frame rate.
Through the steps, the N first videos are collected through the N image collecting devices, the first target frame rate is determined according to the frame rate of each video in the N first videos, and the N first videos are recorded according to the first target frame rate to obtain the first target video. Therefore, the problem that a plurality of videos obtained by shooting the same target object by using a plurality of image acquisition devices cannot be checked in the same video can be solved, the plurality of videos obtained by shooting the same target object by using the plurality of image acquisition devices can be checked in the same video, and the effect of convenience in checking the videos is improved.
Alternatively, the execution subject of the above steps may be a terminal or the like, but is not limited thereto.
In an alternative embodiment, the method further comprises: respectively recording each video in the N first videos according to N preset frame rates to obtain N second videos; determining a second target frame rate according to the frame rate of each of the N second videos, and recording the N second videos according to the second target frame rate to obtain second target videos, wherein the second target videos include the N second videos. In this embodiment, videos acquired by N video acquisition devices are recorded according to a specified frame rate, so as to form N separate files. For example, in the same operation, a scope video, an ultrasound video, and a surgical field video are included, and preset frame rates are respectively specified for recording the three videos, for example, the preset frame rates are respectively 25F \ s, 30F \ s, and 50F \ s, then the scope video, the ultrasound video, and the surgical field video are respectively recorded according to the three preset frame rates, so as to obtain the scope video with the frame rate of 25F \ s, the ultrasound video with the frame rate of 30F \ s, and the surgical field video with the frame rate of 50F \ s. Then, determining a second target frame rate according to the frame rates of the N second video files recorded according to the preset frame rate, wherein the second target frame rate is determined in various ways, for example, the minimum frame rate in the N second videos is determined as the second target frame rate; or, determining the maximum frame rate in the N second videos as the second target frame rate; or selecting a frame rate meeting a preset condition from the N second videos as the second target frame rate. And recording the N second videos in one video at the second target frame rate to obtain a second target video.
In an optional embodiment, the recording N first videos according to the first target frame rate to obtain a first target video includes: under the condition that the frame rate of the first video is greater than the first target frame rate, extracting video frames in the first video at equal intervals to obtain the first target video with the frame rate being the first target frame rate; and under the condition that the frame rate of the first video is less than the first target frame rate, inserting blank frames into video frames of the first video at equal intervals to obtain the first target video with the frame rate being the first target frame rate. In this embodiment, for example, the frame rate of the ultrasound video obtained by the ultrasound image acquisition device in one operation is 10F \ s, i.e. 10 frames of images are played in one second, if the first target frame rate is 5F \ s. Then the image frames are extracted at equal intervals in 10 frames of images played every second in the ultrasound video, i.e. one image is extracted every other image, therefore, the ultrasonic video with the frame rate of 5F \ s is obtained, as shown in FIG. 3, which is a schematic diagram of extracting video frames at equal intervals according to the embodiment of the invention, in the figure, the numbers 1 to 10 refer to 10 frames of images played in one second of the ultrasonic video acquired by the ultrasonic image acquisition device, the 2 nd, 4 th, 6 th, 8 th and 10 th frames of images are extracted at equal intervals, the remaining 1 st, 3 rd, 5 th, 7 th and 9 th frames of images, the frame rate of the ultrasonic video is 5F \ s, or the image of the 1 st, 3 rd, 5 th, 7 th and 9 th frames is extracted, the image of the 2 nd, 4 th, 6 th, 8 th and 10 th frames is remained, the numbers in this embodiment are merely for illustration of the present application and are not limiting, and the ultrasound video frame rate and the first target frame rate satisfy a multiple relationship. For the video that does not satisfy the multiple relationship, for example, the frame rate of the ultrasound video is 10F \ s, if the first target frame rate is 4F \ s, then at this time, an image of every other frame in a video frame of a portion may be extracted, and two images of every other frame in another video frame of the portion may be extracted, as shown in fig. 4, another schematic diagram of extracting a video frame at equal intervals according to an embodiment of the present invention is shown, in the diagram, an image of every other frame is extracted before a 5 th frame image, and after the 5 th frame image, two images of every other frame are extracted.
The same is true for the case that the video frame rate acquired by the image acquisition device is less than the first target frame rate. For example, the frame rate of the endoscope video obtained by the endoscope image acquisition device in one operation is 5F \ s, that is, 5 frames of images are played in one second, if the first target frame rate is 10F \ s. Then, inserting blank frames at equal intervals in 5 frames of images played in each second in the scope video, that is, inserting one frame of blank frame in every other frame of image, so as to obtain the scope video with a frame rate of 10F \ s, as shown in fig. 5, which is a schematic diagram of equal-insertion video frames according to an embodiment of the present invention, in the figure, numbers 1 to 5 refer to 5 frames of images played in one second of the scope video obtained by the scope image acquisition device, and no number refers to a blank frame, and the figure illustrates that blank frames are inserted in every other frame of image at equal intervals. This is the case when the frame rate of the ultrasound video and the first target frame rate satisfy a multiple relationship. For the image that does not satisfy the multiple relationship, for example, the frame rate of the ultrasound video is 5F \ s, and if the first target frame rate is 11F \ s, then a blank frame may be inserted into every other frame of image in one portion of the video frames, and two frames of images may be inserted into every other frame of image in the other portion of the video frames. Fig. 6 is a diagram of another video frame insertion according to an embodiment of the present invention, in which a blank frame is inserted between each frame of image before the 3 rd frame of image, and two frames of images are inserted every other frame of image after the 3 rd frame of image. Of course, this method is only one embodiment, and the specific insertion method may be determined according to actual situations, and equal-interval insertion is guaranteed as much as possible, so as to guarantee that the video after the blank frame is inserted is continuous and undistorted.
In an optional embodiment, the recording each video of the N first videos according to N preset frequencies respectively to obtain N second videos includes: under the condition that the frame rate of the first video is greater than the preset frame rate, extracting video frames in the first video at equal intervals to obtain a second video with the frame rate being the preset frame rate; and under the condition that the frame rate of the first video is less than the preset frame rate, inserting blank frames into the video frames of the first video at equal intervals to obtain the second video with the frame rate being the preset frame rate. In this embodiment, the manner of extracting video frames and inserting blank frames is as in the above-described embodiment.
In an optional embodiment, the recording the N second videos according to the second target frame rate to obtain second target videos includes: under the condition that the frame rate of the second video is greater than the second target frame rate, extracting video frames in the second video at equal intervals to obtain the second target video with the frame rate being the second target frame rate; and under the condition that the frame rate of the second video is less than the second target frame rate, inserting blank frames into the video frames of the second video at equal intervals to obtain the second target video with the frame rate being the second target frame rate. In this embodiment, the manner of extracting video frames and inserting blank frames is as in the above-described embodiment.
In an optional embodiment, after the N first videos are recorded according to the first target frame rate to obtain first target videos, the method further includes: marking at least one time point in the first target video, and receiving input first audio at part or all of the time point of the at least one time point to obtain a marked first marked video; converting the first audio corresponding to the time point into first text information; and integrating the first text information and outputting the first text information in a file form. In the embodiment of the present invention, N videos may be simultaneously marked at least one time point, so as to obtain N marked videos. Optionally, after the N videos are simultaneously marked at least one time point, the audio input by the user may be received at part or all of the time points of the at least one time point, for example, the audio input by a doctor during a surgical procedure may be received, so as to obtain the marked N videos, where the input audio is included in the marked N videos. In the embodiment of the invention, after the recorded video is obtained, positioning playback can be carried out through the marks in the video, namely, the video segments in the video are quickly positioned through the marks in the video. The audio input at each time point in the operation process can be converted into text information, and the text information is integrated into an operation report file to be output, so that the operation report file can be quickly formed.
