At this stage, there are four main directions in the field of machine vision, namely detection, measurement, positioning, and recognition, and visual recognition is only one part of it.
Normally, the machine vision recognition we are exposed to is mainly aimed at the following objects:
Detect the completeness of barcodes or character defects
Read barcodes, QR codes and other data information
Detect if the object is oriented correctly
Detection of the motion state of objects: static, dynamic
The OK/NG product system outputs the corresponding control signal
At this stage, visual recognition technology is not just a simple tool to help us interact with the outside world, many actions have been completely replaced by our human beings, and the future development will not be limited to this after the industry empowers the machine to truly have "vision".
In most scenes, machine vision has more advantages than human vision, they are more accurate, objective, stable, human vision has a natural embodiment, fatigue, environment and other external factors always interfere with the normal working mode, at this time we use barcode readers or industrial cameras to replace the human eye, then for the entire production activities, it is completely possible to achieve twice the result with half the effort.
In the implementation of the project, we must truly realize the machine instead of the human eye to achieve good results, the first is the selection of equipment, the quality of the choice directly affects the cost and efficiency of the entire production line, the selection of the right reading equipment, is not only the cost of the project to save money, but also to improve the effect of the project.

Cognex Vision Systems – What are the key points to choose a line scan vision system?
1. Selection of line scan industrial cameras
Step 1: Calculate the resolution. The width of the object to be inspected (perpendicular to the direction of motion) is divided by the minimum detection accuracy to obtain the required pixel value for each row.
Step 2: Calculate the actual accuracy. Select the camera based on the pixel values above. Then use the ...
