为什么视觉检测设备中CCD相机比CMOS更受欢迎?

浏览量
  市面上大部分机器视觉检测设备是用CCD相机的,也有用CMOS相机的。那么究竟这2种相机有什么不同呢?在定做机器视觉检测设备的时候应该选用哪种规格的工业相机更合适呢?
  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?
  CCD和CMOS有很大区别的,严格意义上说CCD技术更加先进,CMOS应用广泛,而且成本比CCD更低,基本双方都能满足视觉检测的要求。
  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。
  机器视觉检测设备采用CCD相机,是因为CCD相机具备这些优点:受波谱范围宽、畸变小、体积小、重量轻、系统噪声低、功耗小、寿命长、可靠性高。
  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.
  除了CCD相机以外,CMOS相机也广泛用于机器视觉检测设备,这主要取决于客户需求和预算,一般CCD机器视觉检测设备的采购成本比CMOS机器视觉检测设备的采购成本高,但是CCD机器视觉检测设备带来的优势是其它设备不能比拟的。
  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.

  CCD工业相机与CMOS相机的优势在于:
  The advantages of CCD industrial camera and CMOS camera are as follows:
  1、CCD传感器的分辨率通常会优于CMOS传感器的水平;
  The resolution of CCD sensor is usually better than that of CMOS sensor;
  2、CCD传感器的灵敏度要高于CMOS传感器;
  The sensitivity of CCD sensor is higher than that of CMOS sensor;
  3、CCD传感器的噪声水平比CMOS传感器低很多,成像品质更高。
  The noise level of CCD sensor is much lower than that of CMOS sensor, and the imaging quality is higher.
  人们对产品质量的要求越来越高,所以近年来用CCD相机的机器视觉检测设备越来越多,越来越受到青睐,这也取决于CCD相机具备更多的优势。
  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.
