Study on the Length Identification System of Steel Tape Based on LabVIEW Image Processing

摘要

The error of the steel tape itself is an important factor to affect the measured length. According to the identification system of the improved identification procedures of steel tape, the industrial cameras are adopted to take photos for the steel tape and the standard steel tape which will be measured. At the same time, the LabVIEW image processing software is employed to process the photographs. Through comparing the errors of each point in the steel tape calculated by the image recognition, the identification results are finally obtained. The experimental results show that the proposed method is effective.
