Like a network of arteries, pipes and tubes-such as those used for fuel or brake fluid-ensure power and safety in cars. When installing up to 12 different lines in a vehicle, every millimeter counts, because space underneath the vehicle is tight, and mistakes in installation-such as of a brake fluid line-can be detrimental to driving safety.
Many inspection applications require very precise measurements. While software algorithms, via sub pixel interpolation, can provide very fine measurements, they cannot provide accurate or repeatable results if there is any variation in the image created. The choice of optics for a given application can mean the difference between the success and failure of a measurement system.
Too often in the process of selecting machine vision components, decisions on how all the vision components are to be synchronized are left until the end. Many times this can lead to long and costly system integration time, so it is important to look at the synchronization issues before selecting the system components.
The task of illuminating parts for a successful machine vision application has been called by some a science and by others an art. But nearly everyone agrees that correct lighting has a huge impact on the success of any machine vision project.
“At first people refuse to believe that a strange new thing can be done, then they hope it can be done, then they see it can be done-then it is done and the whole world wonders why it was not done centuries ago.”
- frances hodgson burnett, the secret garden.
Vision system integration has come a long way. With increased processing power, more powerful algorithms, and lighting and optics designed for more demanding requirements, more applications can be solved today than ever before.
The term smart camera has been somewhat of a misnomer. It is true that it is a camera, but it has not necessarily been smart. But that is changing as the cameras of the past, which could only work at less than optimal feed speeds and do less than complete image analysis, have evolved into a powerful quality assurance tool.
German beverage industry specialist BBull (Königsbach-Stein, Germany) faced a challenge to inspect tens of thousands of containers an hour. BBull’s high-speed machine vision system Stratec BV 3000W effects an all-around control of labels, tins and bottles.
The DVT 535C entry-level color vision sensor is not limited to a single machine vision function such as color sorting, but can handle a much broader range of applications with a compete set of color tools for sorting, color match and defect detection.
