There are more and more integrated machine vision systems on the market. Choosing the right product for the application is a difficult problem faced by many application customers. This problem itself is difficult to summarize into an inherent formula. Here are some things our company suggests paying attention to:
To a large extent, the application itself determines what product we need to choose. The more detailed we understand and summarize the application itself, the more advantageous it is for us to choose the right product. For example, the detection accuracy and speed we require, the miss and false detection rates required by the production line, the consistency of the product itself, and the possible impact of the production environment.
Most integrated machine vision systems are solidified by vision and software functionality, and vision and software functionality is the core of the integrated machine vision system. We need to pay attention to three aspects of vision functionality:
A. Whether vision and software functionality is complete
In addition to vision functionality, the software functionality of general integrated machine vision systems should also include communication control, human-computer interaction interface, and other tools. Vision functionality is the main part and generally includes tools such as calibration, positioning, presence detection, character recognition, barcode recognition, color analysis, etc.;
B. Whether the performance of vision tools meet the requirements
For the same vision tools, different manufacturers may achieve different effects, so the performance is also different. We can come up with some methods to test and compare;
C. The operability of vision and software tools
Some visual and software function parameters are simple and clear, and are very convenient to use. The visual and software function parameter settings of some products are relatively complicated, and some parameters do not even have clear meanings, making them more cumbersome to use.
Product stability also needs to be paid attention to in the project. Only through actual testing and multi-party consultations can we know. Generally speaking, we can observe the accuracy of visual inspection, whether there is overload protection, whether the circuit will decline after long-term work, whether the interface is reliable, etc.
This can be understood by examining whether the appearance and structure of the product are easy to install, whether the software is flexible and convenient to use, whether the interface function is complete, and whether the product description and help documents are detailed.
This can be understood through multi-party consultations and horizontal comparisons.
When evaluating integrated machine vision systems, a very important question is to choose a provider who can provide extensive product support and training services, which will greatly affect our application development cycle and even the success or failure of our application.
