Product photography as a tool supporting Attribute Agreement Analysis

The goal of the work is to present the method concept of the attribute agreement analysis (evaluation of visual inspection) aided by product photography The results of a proof of concept study in laboratory conditions are presented. The research was performed based on the control process of medical product - a disposable transducer for determining hemodynamic blood parameters. As part of the proof of concept study, a test with three raters and one expert was conducted. For verification purposes, two types of visual control study results were compared, i.e. the level of agreement of assessment decisions made on physical objects and on their digital representatives. A measurement and control system analysis for attributes (MSA-AAA) study were carried out using the Cross-Tab method with Kappa-Cohen’s coefficient and Gwet’s AC1 coefficient. Comparing the results obtained from the study, the final conclusion is that the method using product photography as a supporting tool in AAA is effective. The verification was performed at the Poznan University of Technology, Poland, in the Data Analysis Laboratory with laboratory workstation Orbitvu Alphashot Micro.
