Embodiment 1

[0053] According to the idea proposed by the present invention, the process of gridding the fisheye panoramic image is not limited to forming a fan-shaped grid area, and the fan-shaped grid area can also be cut, which is beneficial for pixel bonding with a plane approximate to a spherical surface. In this embodiment, the fan-shaped area is divided into n parts, where n is 2 and N is 8 for illustration. Such as Figure 6 As shown, the fan-shaped area where point M on the spherical surface is located can be divided into two parts; and because the two hemispheres are symmetrical structures, the southern hemisphere can also be divided in the same way. Here, the chord length is used as the side length of the plane, and the chord plane is used instead of the circular plane.

[0054] Let the radius of the ball be R and the diameter be d. Take N as 8 and n as 2, such as Figure 7 As shown, the relationship between each arc length is as follows:

Abstract

The invention discloses a fisheye image panoramic display method based on spherical panoramic display. The fisheye image panoramic display method comprises the steps: 1, carrying out image gridding; 2, carrying out image orthographic transformation; and 3, spherically attaching and addressing a fisheye image. The fisheye image panoramic display method can be used for panoramic image display of a spherical screen under the environment of a closed cabin and the like, and the fisheye image can be converted into a panoramic image suitable for spherical display. The invention relates to novel spherical panoramic display, and provides a display method, capable of being convenient for reproducing the photosensitively collected and stored double-fish-eye panoramic images on the spherical surface while being compatible to a traditional determinant addressing method, overcoming the distortion storage of the fish eye image, completing the display process from the planar fish eye image to the panoramic display, and achieving the immersion type viewing effect.

Description

technical field [0001] The invention relates to the field of closed cockpit information display and interaction, and the field of panoramic image display, in particular to a fisheye image display method based on spherical panoramic display. Background technique [0002] In recent years, with the rapid development of augmented reality technology, virtual reality technology, aviation and other fields, the requirements for the collection and display of panoramic images have been continuously improved, and the status and value of panoramic display in closed cockpits has become increasingly prominent. [0003] The panoramic display system based on virtual reality is a relatively popular panoramic display method in the existing solutions, but users must wear VR equipment, most of which are VR glasses at present. This will bring inconvenience to the user's actions, and at the same time, this implementation method also has many problems such as small field of vision, edge distortion...
