In addition to the three major features, what else does an industrial camera have?

At the same time, more and more CMOS photosensitive chips are also used in the field of industrial cameras. Because of their lower cost, they can effectively reduce the overall cost of machine vision applications. But the rolling shutter of most CMOS cameras limits its application areas. Dior Digital Image Technology Co., Ltd. specializes in the development and production of CCD and CMOS chip cameras, as well as machine vision related products.

The digital photosensitive chip also converts some physical and chemical properties (such as temperature, acidity, etc.) into digital signals. Photosensitive chips do not perform any analysis on these properties, they simply convert them into digital signals as accurately as possible. Industrial cameras are essentially devices that convert photon signals into digital signals, and the so-called digital signals here are images. These images do not necessarily have to look beautiful. In the field of industrial machine vision, the camera only needs to convert light signals into electrical signals as accurately as possible. Therefore, industrial cameras will not beautify the images they capture. Similarly, the field of machine vision should also try to avoid compressing images.

The application fields of machine vision technology are very wide. Therefore, most industrial cameras are shipped without a lens, but with a lens base. There are two types of lens mounts: C and CS. Industrial cameras produced by Dior support both interfaces. In addition, there are microscopes, telescopes, endoscopes and other lenses based on these assembly interface standards on the market.

The definition of machine vision is not just about capturing images, but also about interacting with machines. For this purpose, industrial cameras provide digital I/O interfaces. The most commonly used one is the external trigger output. In external trigger mode, the camera triggers the shutter based on external events to capture images. A typical application would be to mount a light grid on a conveyor belt and then place an industrial camera next to it. When a target object passes through the grating, a pulse signal is triggered, thereby exposing the camera.

Industrial cameras are digital image sensing devices. The signal, or image, must ultimately be analyzed by a computer. Before performing image analysis, you first need to set camera parameters and capture images. Usually, machine vision requires camera control, image acquisition and image analysis to be integrated into one program. Manufacturers of industrial cameras generally provide programming interfaces for camera control and image acquisition. Typically, these interfaces are proprietary.

Machine vision was first used in industrial production. Various components in this field must keep up with technological trends, but at the same time ensure long-term supply. Dior therefore uses modular components and standardized interfaces when producing industrial cameras.
