Processing is the process of extracting information from a digital image. It can be carried out externally in a PC-based system or internally in a stand-alone machine vision system. Processing is carried out by software and consists of several stages.
1/ An image is acquired using the sensor. In some cases, pre-processing may be required to optimize the image and ensure that all the necessary features stand out.
2/ The software locates the specific characteristics of the part, takes measurements and compares them with the specifications.
3/ A decision is made and the results communicated.
