Virtual Instrumentation for Visual Inspection in Mechatronic Applications

Abstract

Visual inspection becomes very important part of mechatronic and industry applications. The methods which replace human eye and human factor increase speed and reliability of many processes. Virtual instrumentation (LabVIEW from National Instruments e.g.) is very good environment for developing visual inspection tools integrating all basic elements: imaging sensors, I/O hardware and algorithms [1]. Paper focuses on possibilities of designing automated visual inspection link based on LabVIEW for searching and counting of selected parts of products. Algorithms such as Pattern and Geometric Matching, Color Location or Hough Transformation are key elements of all software solutions. Designed visual systems also serves like client communicating with superior system (server) via TCP IP enabling remote control.

“…There are various tools available for implementation. Here NI Vision Assistant [9] is being used as a development tool.…”

“…Its major area is used for image processing applications. Various algorithm and also prototype of an image processing application can build with the Vision Assistant scripting functions [9]. The scripting function records every step of the processing algorithm.…”

“…Therefore, it is needed to analyze the image intensity distribution. Intensity analysis of the gauge image can be performed using NI Vision Assistant tool [9]. The Fig.…”

“…They represent the particles in the image by a set of weighted pixels together. This filter tool is accompanied with LabVIEW [9]. 6 shows NI vision assistant window used for analysing of particle filter area, in particle filter setup area option is selected and in that the minimum range and maximum range of particle's area pixels to be present is fixed.…”
