基于图像识别的液晶盒厚在线测量系统
On-Line Measurement System of Liquid Crystal Cell Gap Based on Image Recognition
摘要
Abstract
The cell gap measurement system of LCD was designed using FPGA as the core chip, in which the image of lights interferences stripe was obtained by using CCD. And it was optimized by the Canny algorithm. It was found that the system has many advantages such as less error, simple structure and easy to run. As a result, the system can be used as on-line automatic measurement system of LCD cell gap, and the relative standard deviation of it can be increased to more than 0. 02%, which implies that the system can be used in the monitoring of LCD cell gap.关键词
