In a liquid-bottle storage system, each bottle is assigned an individual code. These codes provide information about the product, it is required to implement an artificial vision system to read them.
The objective is to evaluate and read the corresponding code, for this purpose an artificial vision system is implemented that identifies and obtains the information contained in it.
In order for a system to be considered optimal, it is essential to analyse its ability to recognise the different characters, which requires lighting capable of generating the ideal contrast.
OCR inspection of artificial vision bottlesIn this case, the chosen lighting is ultraviolet, which, because it has less absorption by the water, generates a high contrast of the code.
Capturing the image with a monochrome sensor and grayscale processing allows us to achieve reliable control information.
Finally, the image is processed through vision libraries.
