Structural Analysis of Size of Machine Vision Measuring System Based on Structured Light and Its Experimental Study

To overcame the problem of low metering accuracy of on-line automatic size measurement and the complexity of its tradition system structure. We propose a size of the machine vision measurement system based on CCD and structured light, and study its application of characteristic information Extraction of part. Then, the paper presents the reliability and error analysis of the measurement system. Experiments show that the scheme has a huge developing space and very bright developing prospects in on-line measurement of part size.
