Evaluation of results by camera system vs. manual result evaluation
• Any visual or manual evaluation, y ranking or classifying of the results is suffering
of the following:
– Visual evaluation & judgment trough the users‘ eyes include the “human error“– Individual impression by the user is time-limited in his mind & remembrance.– No digital documentation.
• An automatic evaluation by a digital vision system can provide the following advantages:
– Exclusion of the “human error“.– “Impression” is exchanged against measurement and the validity & access to the values is not time-limited.
– Objective, precise and repeatable results.– Digital communication
