Referring to fig. 1, fig. 1 is a flowchart illustrating an information importing method of a multimedia file according to an embodiment of the present invention. In this embodiment, the method for importing information of a multimedia file may include the following steps:
s11: at least one image of the multimedia file is acquired.
The multimedia file generally includes multimedia information such as sound, text, and image, for example, an audio file and an image file, the audio file may include a sound file of original sound recorded by a sound recording device, and may also be a Musical performance instruction sequence, which is equivalent to a MIDI (Musical Instrument Digital Interface) file of a Musical score, and the image file may be a picture file, and may also be a video file containing audio and video information, in this embodiment, the multimedia file may be a video file or a picture file.
In step S11, at least one image of the multimedia file is acquired first. Specifically, when the multimedia file is a picture file, the picture file can be regarded as an image, that is, the image of the picture file is acquired; when the multimedia file is a video file, the video file is composed of a plurality of images, and each image is associated with a time information, that is, each time frame has an image, and the time frame t can be 0.01 second, 0.1 second, 0.7 second, 1 second, 2 seconds, 6 seconds, etc., and the time information of the corresponding plurality of images is t, 2t, 3t … … respectively, for example, when t is 0.01 second, image 1 is associated with 0.01 second, image 2 is associated with 0.02 second, image 3 is associated with 0.03 second, etc. When the multimedia file is a video file, at least one image in the video file is acquired, and the number of the images can be 2, 5 or 10. Since the embodiment is used for importing relevant information in a video file, the specific number of acquired images is determined according to the images of the information needing to be imported. After at least one image acquired in step S11, the following step S12 is performed to identify a target area in the image to which information needs to be introduced.
S12: analyzing the at least one image to obtain coordinate information of the target area in the at least one image.
In step S12, the at least one image acquired in step S11 is analyzed, and coordinate information of the target area in the at least one image is acquired.
Specifically, the image of the multimedia file may include a plurality of target areas, and each target area corresponds to one coordinate information. Therefore, in step S12, the coordinate information of all the target regions in the image is acquired after the image is analyzed.
The coordinate information obtaining process is that coordinate axes are established for the image to obtain the coordinates of each pixel in the image, and then the coordinate information of the target area is obtained according to the coordinates of the pixels in the target area. In the process, for the video file, in order to ensure the consistency of the coordinate information, the same reference is adopted for the coordinate axes established for each image in the video file. The coordinate information may be a coordinate value of a central pixel of the target area, or may be a coordinate range of the target area.
In step S12, coordinate information of the target area in at least one image is obtained, that is, when the multimedia file is a picture file, the coordinate information of the target area in the image is obtained, the target area may be one or more, for example, the picture file is a photo of three persons, the head portraits of the three persons are each set as one target area, that is, the picture file includes three target areas, and at this time, the image is analyzed to obtain the coordinate information of each of the three target areas in the image (623, 342), (689, 450), (752, 426).
When the multimedia file is a video file, coordinate information of a target area in at least one image is obtained, similarly, the target area can be one or more, corresponding coordinate information can also be one or more, each image is associated with one time information, namely the target area on the image is associated with the coordinate information corresponding to the target area by the same time information, for example, the video file is a section of a certain player in a football match for dribbling, at the moment, three images in the video file are analyzed, the first image and the second image are both set as the target area of the whole body of the player, the third image is set as the target area of the head of the player, at the moment, the time information associated with the first image is 0.1 second, the time information associated with the second image is 0.2 second, and the time information associated with the third image is 0.3 second, the three images are respectively analyzed and the coordinate information of the target areas is obtained, the first image corresponds to (789, 456), the second image corresponds to (603, 590), and the third image corresponds to (457, 804). The coordinate information acquired in this step S12 is used for association with the data information in the following step S13.
