Microscan Tips and Tricks
My View by Andy Wilson
Vision Systems Spain
It seems as though everyone in our business has seen a flurry of activity within the first quarter of 2016. Our business is up across technology segments, vertical markets, and geographies. 2016 is shaping up to be a banner year for Microscan and the automation market overall. It's an incredible time to be offering and selling automation products and solutions...
The Marketing team loves seeing our Partners recognized for their innovative and successful solutions to customer challenges. I wanted to call out eSolutions for recently being published in Vision Systems Design for their out-of-the-box approach to forestry automation. Pike Lumber asked eSolutions to develop a vision system for automatic log diameter measurement of trees that have already been cut down but still need to be cut into lengths and have their limbs removed.
In this example, eSolutions developed a way for operators to automatically measure timber logs without leaving the inside of the loader cabin. A 5-megapixel Visionscape CCD GigE Camera was mounted to the exterior of the Tigercat tree loader which gives the operator the board feet measure reading (the length and diameter and thus how many boards can be manufactured from a given log). In the past this measuring process was done by hand and took a lot of time and heavy manual labor, and wasn’t always accurate.
Insights about OCR Vision Applications with CIJ Printers (Part 3 of 3)
This article is the third of three articles about OCR vision applications with continuous inkjet printers (CIJ). In this third article, you will learn about the different vision solutions possible with Microscan vision technology. AutoVISION Software incorporates many possible vision tools to choose from, including OCR algorithms with trainable characters, as well as vision tools that are simpler but can be highly effective in the inspection of CIJ print. So how do we know which strategy to follow? In some cases, simple pixel-based algorithms can solve many of the common printing problems of a CIJ printer setup. In some cases pixel-based tools are more effective than OCR tools.
Later on I’m going to describe the machine vision concepts of each approach. I will also point out the advantages and disadvantages of each method. I will provide guidelines for when to use each strategy, and when one strategy may be more effective than another strategy. Once you have this knowledge you will be able to create powerful vision inspection systems for high-speed production lines with CIJ printers using simple components that allow for a rapid yet highly effective design process.
Below are listed various potential vision solutions that are used to solve inline inspection applications challenges of CIJ-printed characters at high speed. They are divided into three primary groups:
