Fisheye lenses have an ultra-wide field of view and can capture a wide range of environments, but there is distortion. Fisheye stitching technology can fuse and process images taken by multiple fisheye lenses, eliminate distortion through correction processing, and finally form a panoramic picture. It has a wide range of applications in many industries. Fisheye stitching technology also has important applications in robot navigation. Fisheye stitching technology provides the robot with panoramic environment perception capability by integrating the ultra-wide-angle vision of multiple fisheye lenses, effectively solving the problems of limited vision and many blind spots in traditional visual navigation. Its core applications in robot navigation are as follows: 1. Environmental perception and map construction Fisheye stitching technology can provide a 360° ultra-wide-angle and wide-viewing environment view, helping robots quickly build high-resolution panoramic maps and fully perceive t...

A fixed focus lens is a lens with a fixed focal length, usually with a larger aperture and higher optical quality. So, how should you choose a fixed focus lens? What factors should you consider when choosing a fixed focus lens? When choosing a fixed focus lens, the following factors need to be considered comprehensively: F ocal length Focal length is one of the first considerations when choosing a fixed focus lens. Focal length determines the field of view of the lens, and fixed focus lenses of different focal lengths are suitable for shooting different scenes and themes. Common focal lengths include 50mm, 85mm, 35mm, etc. Generally speaking, 50mm is the focal length closest to the human eye's perspective, suitable for shooting portraits and daily life scenes; focal lengths of 85mm and above are suitable for telephoto portraits and portraits; focal lengths below 35mm are suitable for shooting wide-angle landscapes and environmental photos. Lenses with different focal lengths are s...

Due to its unique optical design, fisheye lenses have an ultra-wide viewing angle and unique distortion effect. They play an important role and are widely used in panoramic photography, providing an efficient and innovative solution for panoramic photography. 1. The core features of fisheye lenses In short, fisheye lenses have the following core features: Ultra-wide viewing angle Fisheye lenses have a wide viewing angle, usually covering 180° or even more than 230°, and can capture a very wide range of scenes. Short focal length The focal length of a fisheye lens is usually very short, generally between 6-16mm, and belongs to the category of ultra-wide-angle lenses. The short focal length can bring a great depth of field, and can maintain the clarity of most areas of the picture even at a large aperture. Strong barrel distortion The design of the fisheye lens results in obvious barrel distortion at the edge of the image, forming a unique "fisheye effect". This distortion ca...

Fisheye lenses are widely used in many fields, such as photography, military, aerospace, etc., due to their large field of view and unique imaging characteristics. Fisheye lenses have an ultra-wide viewing angle. A single fisheye lens can replace multiple ordinary lenses, reducing the size and weight of the equipment. This is very important in the application of aviation equipment. In general, in the field of aerospace, the application of fisheye lenses mainly includes the following aspects: Aerospace mission monitoring Fisheye lenses can be used to monitor the process of aerospace missions, including the launch, flight and landing of spacecraft. By acquiring panoramic images, the mission execution process can be monitored in all directions, and potential problems can be discovered and dealt with in a timely manner. For example, a high-temperature resistant fisheye lens is installed on the outside of the rocket body to capture the booster separation and fairing jettisoning process in ...

Fisheye lens is a wide-angle lens with a special optical design, which can present a large field of view and distortion effect, and can capture a very wide field of view. In this article, let's learn about the characteristics, applications and usage tips of fisheye lens. 1. Characteristics of fisheye lens ① Wider-angle field of view . The viewing angle of a fisheye lens is usually between 120 and 180 degrees, and compared to other wide-angle lenses, a fisheye lens can capture a wider scene. ② Strong distortion effect . Compared with other lenses, fisheye lenses have a stronger distortion effect, making the straight lines in the image appear curved or bent, presenting a unique and fantastic imaging effect. ③ High light transmittance . Generally speaking, fisheye lenses have high light transmittance, which can achieve better image quality in low light conditions. The characteristics of fisheye lenses are very prominent 2. Application s  of fisheye lens ① Create unique visual effects...

A large aperture fisheye lens is a combination of a fisheye lens with an extremely wide viewing angle and a large aperture. The application of this lens in advertising photography is like a source of creativity, which can give products stronger expressiveness through a unique visual language. In this article, we will start from several aspects to analyze the application advantages of large aperture fisheye lenses in advertising photography. 1. Building an immersive environment The 180° ultra-wide angle of the fisheye lens can include more environmental elements, and with the large aperture blurring the edges, it forms a "wrapped composition" effect, giving the advertising image a more unique atmosphere and making the entire space dynamic and vibrant. For example, when shooting a real estate model room, a single photo taken by a large aperture fisheye lens can simultaneously present a panoramic view of the living room, dining room, and balcony, blurring the edge debris and hi...

To make an analogy, fisheye stitching technology is like tailoring, which can stitch multiple fisheye images into a panoramic image, providing users with a wider field of view and a full range of observation experience. Fisheye stitching technology has important applications in many fields, such as virtual reality (VR) , providing users with a richer and more realistic experience. 1. The working principle of fisheye splicing technology Fisheye lens is an ultra-wide-angle lens with an angle of 180° or more, with a wide field of view, but the image edge is severely distorted. The core of fisheye stitching technology is to correct these distortions and seamlessly stitch multiple images together through image processing and geometric transformation. In short, the working principle of fisheye stitching technology mainly consists of the following steps: ① Image acquisition.  Use a fisheye lens to capture multiple images around a central point, ensuring that there is enough overlap betwe...
