Example 1
Fig. 1 shows a flowchart of an implementation of a barrage display method based on panoramic video according to an embodiment of the present invention. The execution main body of the embodiment of the present invention may be a mobile terminal such as a mobile phone and a tablet computer, may also be a PC (personal computer), and may also be other bullet screen display devices based on a panoramic video, which is not limited herein. As shown in fig. 1, the method mainly includes:
in step S101, a first coordinate range and a first time point of a panoramic video currently viewed by a user are acquired.
It should be noted that, in the process of watching the panoramic video by the user, different parts of the panoramic video can be watched through rotation of the terminal device, gesture dragging operation, mouse operation, keyboard operation, or the like.
The first coordinate range may be a local abscissa range and an ordinate range of the panoramic video displayed on the screen when the user watches the panoramic video currently. The first point in time may be a point in time in the panoramic video when the user is currently watching the panoramic video.
In step S102, bullet screen information matched with the first coordinate range and the first time point is acquired according to the second coordinate range and the second time point corresponding to the bullet screen information.
In the embodiment of the invention, each piece of bullet screen information corresponds to the specified coordinate range and the specified time point, and whether each piece of bullet screen information is matched with the first coordinate range and the first time point of the panoramic video watched by the user currently can be respectively determined according to the second coordinate range and the second time point corresponding to each piece of bullet screen information.
In step S103, the matched bullet screen information is displayed.
For example, the manner of displaying the matched bullet screen information may be to sequentially move and display the matched bullet screen information, for example, sequentially scroll the matched bullet screen information from the right side to the left side of the playing window. For another example, the manner of displaying the matched bullet screen information may be that one piece of bullet screen information occupies one line, or multiple pieces of bullet screen information multiplex one line.
According to the embodiment, the barrage information can be filtered according to the coordinate range of the panoramic video watched by the user, so that different barrages can be displayed when the user rotates the picture to watch different parts of the panoramic video, and the flexibility of barrage display based on the panoramic video and the experience of watching the panoramic video by the user can be improved.
As an example of the embodiment of the present invention, in a process of viewing a panoramic video by a user, if it is detected that a coordinate range of the panoramic video viewed by the user changes, the matched bullet screen information may be obtained according to the new coordinate range, and after the bullet screen information matched according to the original coordinate range is displayed (for example, after the bullet screen information matched according to the original coordinate range is scrolled from the right side of the screen to the left side of the screen and disappears), the bullet screen information matched according to the new coordinate range may be displayed.
Fig. 2 shows a flowchart of an exemplary implementation of a barrage display method based on panoramic video according to an embodiment of the present invention. As shown in fig. 2, the method mainly includes:
in step S201, a first coordinate range and a first time point of a panoramic video currently viewed by a user are acquired.
In step S202, according to the second coordinate range and the second time point corresponding to the bullet screen information, bullet screen information in which the coincidence degree of the second coordinate range and the first coordinate range is greater than the coincidence degree threshold and the time interval between the second time point and the first time point is less than the time threshold is obtained as matched bullet screen information.
The coincidence degree of the second coordinate range and the first coordinate range may be the coincidence degree of areas, for example, according to the second coordinate range corresponding to the barrage information and the first coordinate range of the panoramic video currently viewed by the user, the ratio of the area of the coincidence portion of the area corresponding to the second coordinate range and the area corresponding to the first coordinate range to the total area may be determined as the coincidence degree. The overlap ratio threshold and the time threshold may be set as required, for example, the overlap ratio threshold may be 50%, the time threshold may be 2 seconds, and if the overlap ratio between the second coordinate range corresponding to a certain piece of bullet screen information and the first coordinate range of the panoramic video currently watched by the user is greater than 50%, and the time interval between the second time point corresponding to the bullet screen information and the first time point of the panoramic video currently watched by the user is less than 2 seconds, the bullet screen information may be used as the matched bullet screen information.

In step S302, according to a second coordinate range and a second time point corresponding to the bullet screen information, bullet screen information is obtained, where a coincidence degree between the second coordinate range and the first coordinate range is greater than a coincidence degree threshold, and a time interval between the second time point and the first time point is smaller than a time threshold.
In step S303, it is determined whether the number of the acquired bullet screen information is greater than or equal to a first preset value, if so, step S304 is executed, otherwise, step S305 is executed.
In step S304, the acquired bullet screen information is taken as matching bullet screen information.
In step S305, the overlap ratio threshold is reduced, and the bullet screen information that the overlap ratio between the second coordinate range and the first coordinate range is greater than the overlap ratio threshold and the time interval between the second time point and the first time point is smaller than the time threshold is obtained again.
In step S306, it is determined whether the reduced contact ratio threshold is 0, if so, step S304 is executed, otherwise, step S303 is executed.
As an example of the embodiment of the present invention, after acquiring the bullet screen information in which the coincidence degree of the second coordinate range and the first coordinate range is greater than the coincidence degree threshold and the time interval between the second time point and the first time point is less than the time threshold, it is determined whether the number of the acquired bullet screen information is greater than or equal to a first preset value, for example, the first preset value may be 3. If the number of the acquired bullet screen information is greater than or equal to the first preset value, the acquired bullet screen information can be used as the matched bullet screen information. If the number of the acquired bullet screen information is smaller than the first preset value, the contact ratio threshold value can be gradually reduced until the number of the acquired bullet screen information according to the reduced contact ratio threshold value is larger than or equal to the first preset value, or the reduced contact ratio threshold value is 0. For example, gradually decreasing the overlap threshold may be such that the overlap threshold is halved each time. According to the example, the number of the acquired bullet screen information can be increased by reducing the contact ratio threshold value when the acquired bullet screen information is less, so that the flexibility of bullet screen display based on the panoramic video can be improved, and the experience of watching the bullet screen of the panoramic video by a user is improved.
In step S307, the matched bullet screen information is displayed.
Wherein, the steps S301 and S307 refer to the description of the steps S101 and S103.

in step S401, a first coordinate range and a first time point of a panoramic video currently viewed by a user are acquired.
In step S402, the bullet screen information, in which the coincidence degree of the second coordinate range and the first coordinate range is greater than the coincidence degree threshold and the time interval between the second time point and the first time point is smaller than the time threshold, is obtained according to the second coordinate range and the second time point corresponding to the bullet screen information.
In step S403, it is determined whether the number of the acquired bullet screen information is greater than or equal to a first preset value, if so, step S404 is executed, otherwise, step S405 is executed.
In step S404, the acquired bullet screen information is taken as matching bullet screen information.
In step S405, the overlap ratio threshold is reduced, and the bullet screen information that the overlap ratio between the second coordinate range and the first coordinate range is greater than the overlap ratio threshold and the time interval between the second time point and the first time point is smaller than the time threshold is obtained again.
In step S406, it is determined whether the reduced contact ratio threshold is 0, if so, step S407 is executed, otherwise, step S403 is executed.
In step S407, it is determined whether the number of the acquired bullet screen information is greater than or equal to a first preset value, if so, step S404 is executed, otherwise, step S408 is executed.
In step S408, the bullet screen information that the minimum distance between the second coordinate range and the boundary of the first coordinate range is smaller than the distance threshold and the time interval between the second time point and the first time point is smaller than the time threshold is obtained.
As an example of the embodiment of the present invention, in a case that the reduced contact ratio threshold is 0, if the number of the acquired bullet screen information is still smaller than the first preset value, bullet screen information is acquired, where a minimum distance (which may be a smaller one of the horizontal direction distance and the vertical direction distance, for example) between a boundary of the second coordinate range and the first coordinate range is smaller than the distance threshold, and a time interval between the second time point and the first time point is smaller than the time threshold, and the distance threshold may be 100px, for example. In this example, the bullet screen information in which the coincidence degree of the second coordinate range and the first coordinate range is greater than 0 and the time interval between the second time point and the first time point is smaller than the time threshold, and the bullet screen information in which the minimum distance between the second coordinate range and the boundary of the first coordinate range is smaller than the distance threshold and the time interval between the second time point and the first time point is smaller than the time threshold are taken as the matched bullet screen information. According to the example, the number of the acquired barrage information can be increased when the acquired barrage information is less, so that the flexibility of barrage display based on the panoramic video can be improved, and the experience of watching the barrage of the panoramic video by a user is improved.
In step S409, the matched bullet screen information is displayed.
Wherein, the steps S401 and S409 refer to the description of the steps S101 and S103.
Fig. 5 shows a flowchart of an exemplary implementation of a barrage display method based on panoramic video according to an embodiment of the present invention. As shown in fig. 5, the method mainly includes:

As an example of the embodiment of the present invention, in a case where the barrage information input by the user is received, while the barrage information input by the user is acquired, a coordinate range and a time point of viewing the panoramic video when the user inputs the barrage information are acquired as the second coordinate range and the second time point, and a corresponding relationship between the barrage information input by the user and the second coordinate range and the second time point is established.
For example, the coordinate range and the time point when the user views the panoramic video when the user starts inputting the bullet screen information may be used as the second coordinate range and the second time point, or the coordinate range and the time point when the user views the panoramic video when the user inputs the bullet screen information may be used as the second coordinate range and the second time point, which is not limited herein.
In step S503, a first coordinate range and a first time point at which the user is currently watching the panoramic video are acquired.
In step S504, bullet screen information matched with the first coordinate range and the first time point is acquired according to the second coordinate range and the second time point corresponding to the bullet screen information.
In step S505, the matched bullet screen information is displayed.
Wherein, the steps S503, S504 and S505 refer to the description of the steps S101, S102 and S103.
