Optical remote sensing detection performance evaluation method

Abstract

The invention relates to an optical remote sensing detection performance evaluation method, and belongs to the technical field of remote sensing detection. The optical remote sensing detection performance evaluation index is obtained by comprehensively considering contrast-limited probability and resolution-limited probability of a target and a background; wherein the contrast-limited probabilityis obtained on the basis of considering a contrast factor of a minimum distinguishable contrast and a target background; the resolution-limited probability is obtained by considering a Johnson criterion and a target size factor. A contrast-limited probability model specifically comprises the following influence factors: noise equivalent contrast, contrast of a target and a background, atmospherictransmission, a detection system and a platform, a display system and human eyes. Compared with the prior art, objective factors are comprehensively considered to enable an evaluation result to accordwith a real scene distinguished by human eyes, the probability of discovering, identifying and confirming an interested target is obtained more visually and directly, and the target is more easily accepted by a user; as a pre-evaluation system, the method can help device system design and device model selection.
