The large aperture fisheye lens has the characteristics of large aperture and ultra-wide viewing angle, which can capture extremely wide scenes. It has unique advantages and creative applications in indoor photography and can bring a strong visual impact to the picture. 1. Application scenarios of large aperture fisheye lens in indoor photography Large aperture fisheye lenses are suitable for indoor environments with limited space. Their ultra-wide-angle characteristics plus large aperture can improve the shooting ability in low-light environments and have unique applications in indoor photography. Next, let's take a look at the common application scenarios of large aperture fisheye lenses in indoor photography. A. Architecture and s pace p hotography Large aperture fisheye lenses usually have a 180° or even wider viewing angle, which can capture a wide scene in a very small shooting space, while enhancing the spatial and dynamic sense of the picture through a strong distortion ef...

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...
