Most of the machine vision inspection equipment on the market is made of CCD camera and CMOS camera. So what's the difference between the two cameras? What kind of industrial camera is more suitable for customized machine vision inspection equipment?
There is a big difference between CCD and CMOS. Strictly speaking, CCD technology is more advanced, CMOS is widely used, and the cost is lower than CCD. Basically, both sides can meet the requirements of visual inspection。
The machine vision inspection equipment uses CCD camera because it has these advantages: wide spectrum range, small distortion, small volume, light weight, low system noise, low power consumption, long life and high reliability.
In addition to CCD camera, CMOS camera is also widely used in machine vision inspection equipment, which mainly depends on customer demand and budget. Generally, the purchase cost of CCD machine vision inspection equipment is higher than that of CMOS machine vision inspection equipment, but the advantages of CCD machine vision inspection equipment are incomparable with other equipment.
The advantages of CCD industrial camera and CMOS camera are as follows:
The resolution of CCD sensor is usually better than that of CMOS sensor;
The sensitivity of CCD sensor is higher than that of CMOS sensor;
The noise level of CCD sensor is much lower than that of CMOS sensor, and the imaging quality is higher.
People have higher and higher requirements for product quality, so in recent years, there are more and more machine vision inspection equipment with CCD camera, which is more and more popular, which also depends on the advantages of CCD camera.
