機器視覺在線檢測技術從安裝方式上分為固定式和動態式，視覺檢測系統從測量的方法上分為采用照相機拍照系統和激光系統兩種方式；從應用領域上分為定位檢測功能、尺寸檢測、型面檢測和功能匹配等幾個方面。
Machine vision on-line inspection technology can be divided into fixed type and dynamic type from installation mode; vision inspection system can be divided into two ways: camera photographing system and laser system in terms of measurement method; and it can be divided into positioning detection function, size detection, surface detection and function matching from the application field.
在自動化汽車生產線中，視覺檢測系統必要時需要同機器人匹配應用，并與生產線的PLC控制系統建立聯接，以實現測量、檢測、定位和識別的功能。
In the automatic automobile production line, the vision inspection system needs to match with the robot when necessary, and establish the connection with the PLC control system of the production line, so as to realize the functions of measurement, detection, positioning and identification.
視覺檢測系統具有如下特點：采用非接觸式測量方式，提高了相應速度，對生產線影響小；具有長時間的穩定、可靠地重復工作的性能，適用于汽車連續化的流水線作業；適合在安全風險高、人機工程惡劣和環境差的區域工作。諸多優點使視覺檢測系統在汽車行業中得到了廣泛的應用。
The visual inspection system has the following characteristics: the non-contact measurement method is adopted to improve the corresponding speed, and has little impact on the production line; it has the performance of long-time stable and reliable repeated work, which is suitable for continuous assembly line operation of automobile; it is suitable for working in areas with high safety risk, poor human and mechanical engineering and poor environment. Many advantages make the visual inspection system in the automotive industry has been widely used.
視覺測量系統工作原理：使用平面激光照射被測物體表面，采集二維平面數據；使用激光線照射被測物體采集第三維數據；根據采集數據通過專業軟件進行分析；通過相關算法得出被測物體或特征的位移、形變以及其他幾何特征的變化。
The working principle of vision measurement system: using plane laser to irradiate the surface of the object to collect two-dimensional plane data; using laser line to irradiate the measured object to collect the third dimensional data; analyzing the collected data through professional software; obtaining the displacement, deformation and other geometric characteristics changes of the measured object or characteristics through relevant algorithms.
機器人裝配精確定位，在現場自動化工位，如頂蓋安裝、機器人激光焊接、門蓋的安裝以及自動涂膠等工藝，都需要先進行精確定位，機器人對定位數據進行分析后進行正確的操作，以達到工藝的穩定性。此種定位采取激光測量的方式，通常采用固定方式。
Robot assembly precise positioning, in the field automation station, such as top cover installation, robot laser welding, door cover installation and automatic gluing and other processes, need to carry out accurate positioning first. The robot will analyze the positioning data and then operate correctly to achieve the stability of the process. This kind of positioning adopts the way of laser measurement, and usually adopts the fixed mode.
在線門蓋型面檢測，通常采用照相系統或激光面掃描等對外覆蓋件的輪廓或特征進行在線檢測，減少了人工搬運、下線的問題，實現100%在線檢測，面掃描也是觸發式測量設備無法完全替代的檢測方法。
Online door cover profile detection usually uses camera system or laser surface scanning to detect the outline or characteristics of external panel, which reduces the problems of manual handling and offline, and realizes 100% online detection. Surface scanning is also a testing method that trigger measurement equipment cannot completely replace.
此外，在線檢測設備還可以對機器人涂膠的軌跡和位置等進行測量監控，并對軌跡的偏差設定報警限，從而實現自動監控。
In addition, the online detection equipment can also measure and monitor the trajectory and position of the robot, and set the alarm limit for the deviation of the trajectory, so as to realize the automatic monitoring.
