Abstract:

Three-dimensional hand scanning relies on participants to hold a position for a certain amount of time. Any involuntary movements or posture changes can lead to distortions in the three-dimensional scans. When color-capture is possible, clear visible landmarks are needed to create reliable digital landmarks and to take accurate digital measurements. Visual analysis of three-dimensional scanning to assess scan quality for anthropometric data collection is not often considered. However, the quality of the scan can greatly affect the reliability and precision of the anthropometric measurements. This study examined a visual analysis of the three-dimensional hand models provided from two (2) full-color hand-held three-dimensional scanners (the Occipital Structure Sensor and Artec Leo) in the post-processing stage to determine the three-dimensional visual reliability and three-dimensional visual precision for twelve (12) participants. The Post-Processing Visual Analysis Likert Scale, developed by Juhnke, Pokorny, and Griffin (2021), was used to provide clear definitions for each location to quantify the scans' overall quality within the visual assessment. This study found that the Occipital Structure Sensor and Artec Leo are comparable within the visual reliability and visual precision analyses at all locations, except for the Visibility of Landmark location. The visual reliability and precision analyses were crucial to understanding where the quality of the scans taken by both scanners might affect the outcomes from the anthropometric data collection. This study provides a method of visual analysis of the three-dimensional models provided by three-dimensional scanners to determine the three-dimensional visual reliability and three-dimensional visual precision for better anthropometric data collection outcomes.
