Under the large-scale transformation of global Industry 4.0, the development and application of machine vision are increasingly favored by the manufacturing industry, and industrial camera, as the “eye” of machine vision, is naturally the core component of machine vision.
However, for many manufacturing players who have just entered Industry 4.0, they still do not know much about industrial cameras and cannot distinguish the difference between industrial cameras and civilian cameras.
1. Object-oriented distinction
Industrial cameras are specialized for manufacturers.
Not the pursuit of beauty, the camera compact structure is not easy to damage, continuous working time is long, can be used in the harsh environment, with strong performance, stable and reliable, easy to install and other advantages.
Ordinary cameras are aimed at civilian consumers.
Usually the pursuit of beautiful appearance, good portability, but the overall structure of the camera is relatively loose, and can not work continuously for 24 hours or more, it is difficult to be fixed on the production equipment.
2. Frame rate difference
Industrial cameras can have short exposure times and can capture objects moving at high speed. Generally, the shutter time can be adjusted from 1/100000 seconds to 10 seconds. With the machine vision light source and strobe controller, the shutter time can be set at the microsecond level.
The exposure time of ordinary cameras is relatively long, generally can only shoot 2-3 images per second, it is difficult to capture high-speed moving objects, or the captured image output, compared with the shooting effect of industrial cameras under the same conditions.
3. Scan the difference
Industrial cameras are progressive scanning, because progressive scanning image sensors are difficult to produce, low yield, small shipments, expensive, and its advantage is that it can clearly capture fast moving objects.
Ordinary cameras often scan interleaved, or even three rows apart, because there is no need to pursue high-definition capture. For ordinary cameras in pursuit of economic benefits, interleaved image sensors may be the best choice.
4. Spectral difference
Industrial cameras usually output bare data and their spectral range is often wide, which is suitable for high-quality image processing algorithms, such as machine vision applications.
The spectral range of the pictures taken by ordinary cameras is only suitable for human vision, and the image quality is poor after compression, which is not conducive to analysis and processing.
