FIELD-OF-VIEW, DETECTION RANGE, AND FALSE ALARM TRADE-OFFS IN VISION-BASED AIRCRAFT DETECTION

摘要

This paper presents a survey of previously presented vision-based aircraft detection flight test, and then presents new flight test results examining the impact of camera field-of-view choice on the detection range and false alarm rate characteristics of a vision-based aircraft detection technique. Using data collected from approaching aircraft, we examine the impact of camera field-of-view choice and confirm that, when aiming for similar levels of detection confidence, an improvement in detection range can be obtained by choosing a smaller effective field-of-view (in terms of degrees per pixel).
