VisionBank Character Recognition-Bottle Cap

In the past application cases, I believe that everyone has a certain understanding of VisionBank intelligent vision software. VisionBank software is easy to operate and powerful. Today, I will introduce the character recognition detection module here.

Character detection, also known as OCR or OCV detection, is to identify and detect characters printed or engraved on the surface of various electronic components, printed packaging products, mobile phone keyboards, computer keyboards and other items. Common characters include numbers and English letters. , Symbols, etc. This article introduces the case of character recognition on the bottle cap as an example:

Because the bottle cap itself is reflective and has a certain curved surface, the picture effect provided by the user can only be described in general, but fortunately, the entire character is still clear. In addition, the position of the bottle cap is relatively random during actual placement, and the test results as follows:

In the above case, we first preprocessed the picture, hoping to make the characters more prominent. Since the position of the bottle cap is not fixed, the feature positioning was performed, so that the characters can be correctly detected every time, and then we use The self-reading recognition detection module can quickly and accurately get the results. If an abnormality occurs, such as a character printing error, missing printing, etc., it can prompt an alarm or control the machine to stop. It can output the control signal after detecting the non-conforming workpieces, reject the non-conforming products, and the degree of automatization is quite high.

If you have relevant testing requirements, you can contact the relevant personnel of Veishi Intelligent Manufacturing for photo verification. We will provide you with the most cost-effective solution. Users are welcome to inquire.
