Abstract
The invention discloses a method for setting a panoramic player FOV (field of view), which is used for watching panoramic contents under 3DoF (DoF), providing various settings by adjusting the visual field and enhancing the user experience. Firstly, if the user watches a concert performance, the height is adjusted to be as high as that of the audience; and secondly, adjusting the distance to approach the performer. Through the terminal equipment of vwatching, the different modes of vwatching of intelligence adaptation, its characteristics are that the function is practical, easy operation, and user's study is with low costs, and the effect ideal of realization has satisfied user's true demand, really triggers from user experience, solves user's true demand, and the function realization principle is simple.
Description
Technical Field
The invention relates to the technical field of panoramic players, in particular to a method for setting an FOV (field of view) of a panoramic player.
Background
When the panoramic content is watched by using the virtual reality terminal, sometimes because the panoramic camera is far away from the performer, when the panoramic camera is far away, the visual field is enlarged, and more content can be seen. This is likely to interfere with viewers in the class of concert performances. The viewer needs a function to bring the performer closer. Therefore, those skilled in the art provide a method for setting the FOV of a panoramic player, which can set the field of view and distance of a user, and solve the problem of poor experience when viewing panoramic content.
Disclosure of Invention
The present invention is directed to a method for setting a FOV of a panoramic player, so as to solve the problems mentioned in the background art.
In order to achieve the purpose, the invention provides the following technical scheme:
a method for setting a panoramic player FOV is realized by setting two dimensions of the panoramic player FOV, and comprises the following steps of:
1) the panoramic video player takes out pictures from the video source one frame by one frame;
2) pasting the extracted picture on the surface of a sphere, converting the picture of the frame into a Texture2D material sphere, and pasting the material sphere on the sphere for presentation;
3) rendering the image at the center of the sphere in real time by using a virtual camera;
4) outputting the rendered image to a screen or a wearable display device;
5) adjusting the height of the visual angle, and correspondingly adjusting the Y coordinate of the virtual rendering camera by the player to obtain the effect of lifting the visual angle;
6) and adjusting the size of the visual angle, adjusting the FOV attribute of the virtual rendering camera by the player, playing the effects of enlarging and reducing the picture when the player runs at a low value, and playing the effect of adjusting the visual field distortion when the player runs at a high value.
Compared with the prior art, the invention has the beneficial effects that:
1. the function is practical, easy operation, and user's study is with low costs.
2. The realized effect is ideal, and the real requirements of users are met.
3. The real requirement of the user is really solved by the triggering of the user experience.
4. The function realization principle is simple.

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.
Referring to fig. 1-2, in an embodiment of the present invention, a method for setting a FOV of a panoramic player is implemented by setting two dimensions of the FOV of the panoramic player, including a viewing angle height and a viewing angle size, and includes the following specific steps:
1) the panoramic video player takes out pictures from the video source one frame by one frame;
2) pasting the extracted picture on the surface of a sphere, converting the picture of the frame into a Texture2D material sphere, and pasting the material sphere on the sphere for presentation;
3) rendering the image at the center of the sphere in real time by using a virtual camera;
4) outputting the rendered image to a screen or a wearable display device;
5) adjusting the height of the visual angle, and correspondingly adjusting the Y coordinate of the virtual rendering camera by the player to obtain the effect of lifting the visual angle;
6) and adjusting the size of the visual angle, adjusting the FOV attribute of the virtual rendering camera by the player, playing the effects of enlarging and reducing the picture when the player runs at a low value, and playing the effect of adjusting the visual field distortion when the player runs at a high value.
The working principle of the invention is as follows:
more users are now likely to experience a wider field of view in the experience. The two types of FOVs (monocular and binocular) together constitute the field of view of a human. Monocular vision describes the vision of one of our eyes. For a healthy eye, the horizontal single field is between 170-175, the angle is from pupil to nose, the nose angle is typically 60-65, and for the greater nose the nose angle is smaller, and the general field of vision from our pupil to our head is wider, typically 100-110. The wider the field of view, the more likely it is for the user to have a feeling of being personally on the scene.
The panoramic content is watched under the 3DoF, and multiple settings are provided through adjusting the visual field, so that the user experience is enhanced. Firstly, if the user watches a concert performance, the height is adjusted to be as high as that of the audience; and secondly, adjusting the distance to approach the performer. Through the terminal equipment of vwatching, different modes of vwatching of intelligence adaptation.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
