Vision Machine Outer Diameter Checking
A machine vision system for bearing outer diameter inspection has been developed in this paper. The infinite objective of optical system is applied to diameter measurement system. The paper provides a method for measuring the size of objects based on polynomial interpolation. The technology of CCD image stagger is applied in the paper. The method can avoid space between pixels abstraction theoretically, so higher measurement accuracy is gained. The experiment results show that the system has many advantages such as non- touch , high speed and higher precision.
Machine detected points have higher accuracy, such as the precision of detecting the square corner points on the calibration plate, the measurement accuracy of the measurement model can be higher. The main factor affecting the measurement accuracy of the model is the error of the detected points on the ellipse, and the error is mainly affected by the surface roughness and the rotation speed of the shaft. Therefore, based on this measurement model, if a higher-precision measurement of the shaft diameter is required, to study the influence law of shaft surface roughness and rotation speed on the detection accuracy of the light stripe center is a desirable research direction.
The major components of a machine vision system include the lighting, lens, image sensor, vision processing, and communications.
2D laser scanners offer a non-contact solution to create a profile of the object to accurately measure the diameter. Acuity laser sensors can be used to measure outer diameter (OD) of job.

VISION MACHINE
Machine vision is the ability of a computer to see; it employs one or more video cameras, analog-to-digital conversion and digital signal processing. The resulting data goes to a computer or robot controller. Machine vision is similar in complexity to voice recognition.
Machine vision applications are used in a range of industries to perform various tasks, including the following: mechanical component analysis. Machine vision is used in the construction of circuit boards for tasks such as solder paste inspection and component placement. Optical character recognition (OCR).
