AOI Testing

Automated optical inspection (AOI) technology, also known as machine vision inspection (MVI) technology or automated visual inspection (AVI) technology. In some industries, such as flat panel display, semiconductor, solar, and other manufacturing industries, the term AOI is more popular and known. But AOI and MVI / AVI are still slightly different in concept and function.

In a narrow sense, MVI is an emerging scientific technology that integrates image sensing technology, data processing technology, motion control technology, and performs tasks such as measurement, detection, recognition, and guidance in the industrial production process. The basic principle of MVI uses optical imaging methods (such as a camera, or a complex optical imaging system) to simulate the visual imaging function of the human eye, use a computer processing system instead of the human brain to perform data processing, and finally feedback the results to the implementing agency (such as mechanical Hand) to complete various prescribed tasks instead of manpower.

Broadly speaking, MVI is a technology that stimulates and expands the functions of human eyes, brains, and hands. Its definition may have subtle differences in different application areas, but they cannot leave two fundamental methods and technologies. Obtain the required information from the image, and then feed it back to the automatic actuator to complete the specific task. It can be said that the automatic detection technology based on any image sensing method (such as visible light imaging, infrared imaging, X-ray imaging, ultrasound imaging, etc.) can be considered as MVI or AVI. When using optical imaging methods, MVI actually becomes AOI. Therefore, AOI can be regarded as a special case of MVI.

According to different imaging methods, AOI can be divided into three-dimensional (3D) AOI and two-dimensional (2D) AOI. The three-dimensional AOI is mainly used for the measurement of object shape and geometric parameters, part grouping, positioning, recognition, robot guidance, etc.; AOI is mainly used for product appearance (color, defects, etc.) detection, classification of different objects or appearances, detection, and classification of good and defective products, etc.
