Industrial lenses are designed specifically for industrial applications. They have the characteristics of high resolution, low distortion, high contrast, etc. They are widely used in the field of machine vision. In this article, we will learn about them together. Industrial lenses have a wide range of specific applications in the field of machine vision, including but not limited to the following aspects: Product inspection and quality control Industrial lenses are widely used in product inspection and quality control. Through machine vision systems, the shape, surface defects, dimensional accuracy, color consistency, assembly quality and other characteristics of products can be inspected and imaged for analysis. This can achieve automated product quality inspection and real-time measurement, improve production efficiency, reduce human errors, and realize efficient automated production for enterprises. Robot vision navigation Industrial lenses combined with machine vision technology c...

What is a fisheye lens ?   Fisheye lens is an extreme ultra-wide-angle lens with two main features: short focal length and wide field of view. "Fisheye lens" is its common name. In order to maximize the viewing angle of the lens, the front lens of this lens is very short in diameter and bulges toward the front of the lens in a parabolic shape, which is quite similar to the eyes of a fish, hence the name "fisheye lens". People also call the images taken by it "fisheye images". The field of view of the fisheye lens is extremely large, and a frame of image it captures contains very rich information, so it does not need to rotate or scan and can work in a staring manner. Combined with the advantages of small size and strong concealment, the fisheye lens has unique application value in various fields. 1. The principle of fisheye lens When the human eyeball rotates to observe, the viewing angle can be expanded to 188 degrees. When the eyeball does not rotate, th...

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 ...
