Fisheye stitching technology is the result of stitching multiple photos taken with an ultra-wide-angle fisheye lens to generate a panoramic image covering 360° or even a spherical surface. Fisheye stitching technology is an efficient means of creation in panoramic photography, and its application is of great significance to panoramic photography.
1.The principle of fisheye stitching technology
Before understanding the application of fisheye stitching technology, let’s take a look at the principle of fisheye stitching technology:
Fisheye stitching technology mainly relies on the ultra-wide-angle imaging characteristics of fisheye lenses. Fisheye lenses have extremely wide-angle characteristics, and the viewing angle can usually reach 180°~220°. A single image can cover a very large area.
In theory, only two images are needed to cover a 360° panoramic range. However, due to the serious distortion problem of fisheye images themselves, 2-4 images are generally required for fisheye stitching, and image correction and feature extraction and other processing steps are required before stitching.
The main processing flow of fisheye stitching technology is: shooting fisheye images → image correction → feature extraction and matching → image stitching and fusion → post-processing, and finally generating a seamless panorama.

2.Application of fisheye stitching technology in panoramic photography
In general, the application of fisheye stitching technology in panoramic photography mainly has the following manifestations:
Security monitoring applications
In security monitoring, panoramic images stitched by fisheye lenses can cover a larger monitoring area and improve security. This type of monitoring is widely used in factory workshops, warehouses and other scenes.
Virtual Reality (VR) and Augmented Reality (AR) applications
The immersive experience of VR/AR requires 360° panoramic images without blind spots, allowing users to explore the virtual environment from a 360° perspective.
Fisheye stitching technology can be used to stitch a panorama with a small number of images, greatly improving efficiency. For example, panoramic scenes such as VR guided tours of scenic spots and online house viewing for real estate use fisheye stitching technology.
Travel and landscape photography applications
Panoramic photography with fisheye stitching is also used in tourism and landscape photography. For example, an immersive perspective is used to record large scenes such as canyons and lakes, or to shoot a panoramic view of the Milky Way in the starry sky.
For example, when shooting the aurora, fisheye stitching technology is used to completely integrate the aurora arc with the snow-capped mountains on the ground, showing a shocking sense of unity between heaven and earth.

Art and creative photography applications
Photographers also often use fisheye stitching technology to create unique works of art. Photographers can use the distortion characteristics of fisheyes to create creative and imaginative works of art through clever composition and shooting angles, such as distorting buildings into spheres or creating creative visual effects through stitching.
Robot navigation applications
Panoramic images created using fisheye stitching can be used for environmental modeling and path planning, helping to improve the robot’s environmental perception capabilities and providing support for the robot’s precise navigation.
Drone aerial photography applications
Fisheye stitched panoramic images can also be used for panoramic coverage of drone aerial photography scenes to increase the breadth and depth of the image. For example, in drone landscape photography, the magnificence of large scenes can be fully displayed, allowing the audience to feel an immersive visual impact.

Panoramic application of indoor space
When shooting indoor spaces, using fisheye stitching technology can fully present the layout and details of the entire room.
For example, when shooting a luxurious hotel lobby, the ceiling, front desk, lounge area, stairs and other parts of the lobby can be photographed through a fisheye lens, and a panoramic image can be stitched together through fisheye stitching to clearly present the overall structure and luxurious atmosphere of the lobby, allowing the audience to feel as if they are in it and more intuitively feel the size, layout and decoration style of the hotel space.
It can be seen that fisheye stitching technology has significant advantages in panoramic photography, but it also faces considerable challenges, such as image distortion problems that may affect the stitching effect, brightness and color differences between different lenses that may cause stitching seams and affect image quality, etc. Of course, with the development of computer vision and deep learning technology in the future, fisheye stitching technology will continue to improve, and will play an important role in more fields in the future, providing users with a more immersive and realistic visual experience.
