Xinxiwang explains to you the key points of machine vision software selection

        With the vigorous development of China's manufacturing industry, our country is becoming one of the most active areas for the development of machine vision in the world. The large-scale application areas started from the electronics, pharmaceutical and other industries, and gradually expanded to the packaging, automobile and other fields, and there are also many applications in the transportation, printing and other industries. Of course, machine vision software has become an important part of automation. Below, the editor of Xinxiwang will explain to you the key points of selecting vision software:

1. Accuracy of locator

The accurate positioning of objects or features is an important function of an inspection system or a vision-guided motion system. Traditional object positioning uses gray value correlation to identify objects. Although this technology is widely used, it lacks stability when image quality deteriorates. Deterioration in image quality may be due to factors such as clutter, brightness differences, and concealment. In contrast, geometric target location is a newer method that uses generalization of the target to identify the target and its characteristics. Most of the image processing software independently developed by Weishi Image adopts the geometric target positioning method and is extremely efficient, which can effectively help users solve positioning problems.

2. Tool library or application software

Machine vision software is mainly sold in two typical ways: one is a tool library containing a variety of processing algorithms, and the other is application software that is dedicated to a certain type of special work. Both have their pros and cons, and you need to confirm this feature first before making a choice. The image processing software provided by Weishi Image includes these two types, which can not only provide professional applications but also meet the changing needs of customers.

3. Easy to program and operate

A simple and intuitive graphical interface is the key to easy use and setup. The main difference between today's machine vision products is their graphical interface. The interface is roughly evaluated from two aspects: "settings" and "operations". To an engineer it may be very complex, but to an operator it should be very simple.

4. Pixel accuracy

The resolution of a visual system is the smallest feature that the system can resolve. For example, using a 640x480 pixel computer image with a field of view (FOV) of 1'' will result in a resolution of 1/640 or 0.00156''. In fact, machine vision algorithms have sub-pixel capabilities. That is, these algorithms can measure or derive units smaller than a pixel.

5. Easy to upgrade

Machine vision systems can be used in a variety of situations, and their applications range from stylish cameras to surveillance systems. When selecting a system you should consider future upgrades to the system. General-purpose vision software systems are very easy to upgrade. End users may think about future needs for the system in terms of additional cameras, changes in lighting, changes in visual tools, etc.

6. Image preprocessing algorithm

Most image processing software provides preprocessing algorithms, so you need to compare the richness, efficiency, etc. they provide.

7. System integration

If you are not very proficient in machine vision technology, then you will need a system integrator for your project. The ideal visual product can be widely accepted by the system integrator.
