Resolution Requirements for Identification of Targets in Television Imagery

摘要

The purpose of this study was to empirically relate the probability of correctly identifying targets in television imagery to the number of scanning lines traversing the target. Five different targets (scaled models) were investigated: an aircraft, oil storage tanks, a bridge and two buildings. Each target was located in different positions and orientations on a scaled terrain model. A television system scanned the terrain model and presented the image on a monitor. Observers attempted to identify which one of the five targets was located within a small, inscribed area. (Author)
