JUDGMENT OF VOLUME FROM PHOTOGRAPHS OF COMPLEX, IRREGULAR SHAPES AvCIR 61-18

摘要

Accident investigation procedures involve estimates or judgments or damage to the aircraft. One aspect of these postcrash observations of particular relevance to crash injury studies is the reduction in volume of the occupiable area. It has been proposed that a panel of analysts, working from photographs, could provide more accurate and reliable estimates of such characteristics than would a single field investigator working under uncontrolled conditions. The present study examines the feasibility of making judgments of volume reduction, a three-dimensional problem, from two-dimensional representatives of objects, and attempts to identify the perceptual factors that might influence such judgments.
