在了解数据接口之前,我们先来认识下什么是工业相机,工业相机的定义是机器视觉检测系统中的一个关键组件,其最本质的功能就是将光信号转变成有序的电信号。选择合适的相机也是机器视觉检测系统设计中的重要环节,相机的选择不仅直接决定所采集到的图像分辨率、图像质量等,同时也与整个系统的运行模式直接相关。而将相机采集图像进行传输,就需要通过相机的接口来实现,将图像数据传输到我们的设备上。
Before understanding the data interface, let's first understand what is an industrial camera. The definition of an industrial camera is a key component in the machine vision detection system. Its most essential function is to transform the optical signal into an ordered electrical signal. Choosing the right camera is also an important part in the design of machine vision detection system. The choice of camera not only directly determines the resolution and quality of the collected images, but also directly relates to the operation mode of the whole system. To transmit the image collected by the camera, the interface of the camera is required to transmit the image data to our device.

工业相机的接口分为:USB2.0/3.0、1394a/1394b、CamerLink、Gige、CoaXPress等类型的接口。但目前在机器视觉检测中,应用最广泛的接口是Gige(以太网)接口,以太网接口在传输速度、距离、成本等方面较其他接口具有很大的优势;下图为机器视觉检测系统的工业相机常见的接口比较。

The interfaces of industrial cameras are divided into: usb2.0/3.0, 1394a/1394b, CamerLink, Gige, CoaXPress and other types of interfaces. However, the most widely used interface in machine vision detection is Gige (Ethernet) interface, which has great advantages over other interfaces in terms of transmission speed, distance and cost. The following figure shows the common interface comparison of industrial cameras in the machine vision inspection system.

Gige接口特点,拓展性好,传输数据长度最长可伸展至100m,转播设备上可无限延长,带宽达1Gbit,因此大量的数据可即时得到传输,可使用标准的NIC卡,经济性好,可使用廉价电缆,如可使用通用的Ethernet电缆(CAT-6)和标准的连接器,可以很容易集成,且集成费用低,可管理维护性及广泛应用性。以上就是机器视觉检测之工业相机如何选择接口的知识解答。
Gige interface characteristic, good expansibility, data transmission can be extended to 100 m length of the longest, broadcasting equipment can be infinitely extended, 1 gbit bandwidth, therefore a large amount of data can be real-time transmission, can use the standard NIC card, economy is good, can use cheap cable, such as can use general Ethernet cable (CAT - 6) and a standard connector, can be easily integrated, and low cost of integration, management, maintenance and wide applicability. The above is the machine vision inspection of the industrial camera how to choose the interface of knowledge.
