The one chip computer is added in the scalling-off detecting device.

According to the dimensional inspection,taking the thin sheet part of Head Gimbal Assembly(HGA) of the computer hard disk as an object,a line type industrial camera is used to acquire the image of the inspected part by line scanning.

Research of Color Difference and Dimension Measurement of Ceramic Tile Based on CCD;

Now, most of Chinese bearing factories in dimension measurement for bearing have been mainly dependent on mechanical or optical instruments in sampling inspection way.

A vision system for on-line dimension measurement of ceramic tile;

Apple image processing and size detecting:;

Then, it discusses the composition and design of optical system of the high precision size detecting system with linear CCD, and the method of improvment in measuring precision of the detecting system is also presented, such as the high speed visual signal sampling card, dual-value detecting circuit, digital image processing with computer.

The paper probes into the application of MCS-51 Micro-controller Unit to a dynamic dimensional measurement using infrared rays,for the composing of an infrared dynamic dimensional measurement system,a detection operating principle,data gathering,and the processing and controlling of the AD574.
