Eight reasons you should consider when choosing visual inspection equipment

Industrial visual inspection machine manufacturers explain eight reasons that should be considered when purchasing visual inspection equipment.

As an important part of the machine vision system, image processing software mainly realizes the detection of specific target features through image analysis, processing and recognition. Due to the wide application of machine vision systems in modern industrial fields, the machine vision software technology applied to machine vision systems has developed rapidly.

At present, the competition of machines has shifted from the competition of purely pursuing the multi-function of software to the competition of the accuracy and efficiency of detection algorithms. Conventional machine vision software can provide multiple detection functions such as search, optical character recognition, edge blob analysis, and caliper tools. However, due to the different algorithm design, the detection effect is quite different. Excellent machine vision software can quickly and accurately detect the target features in the image, and minimize the dependence on the hardware system. Faced with the machine vision software of different companies, what factors should customers consider when choosing?

1. Positioning

The precise positioning of objects or features is an important function of a detection system or a vision-guided movement system.

2. Optical device and lighting

Appropriate optics and lighting are critical to the success of vision applications.

3. Complete tool set to multiple tools tied together

Machine vision software is mainly sold in two typical forms, one is a complete set of vision tools, and the other is a tool application for specific tasks. The application of the end user will decide whether to use a complete set of vision tools or use Numerous specific tools.

4. Convenient, simple and intuitive graphical interface for programming and operation is the key to easy use and setup

The main difference between machine vision products is their image interface, which should be evaluated from two aspects: "settings" and "operations".

5. Sub-pixel accuracy

Machine vision systems have sub-pixel capabilities, that is, these algorithms can measure or derive units smaller than one pixel.

6. Future upgrades

The machine vision system can be applied to two occasions, and future upgrades of the system should be considered when choosing a system.

7. Image preprocessing

The image preprocessing algorithm can magnify the feature points of the image so that the visual tools can better detect them.

8. Visually guided movement

If your application requires a vision system to guide the robot, then you must know how the vision system and the motion system are integrated.
