| 摘 要： | 发展红外成象导引技术对于提高命中精度和作战有效性具有重要的意义。本文研究了采用红外成象传感器对军舰目标要害部位的自动瞄准和定位问题，提出并用软件实现了一套实时处理方案。选定目标吃水线下方为瞄准点，采用形心跟踪和帧帧相关匹配的多模方式，分别用于处理目标溢出视场前和溢出视场后的情况，能在目标处于各种姿态下可靠地选择瞄准点并保证定位精度，对６８帧红外目标图象的仿真实验取得了令人满意的结果。

| Abstract: | Development of infrared imaging guidance technology is of greatimportance to improve pointing accuracy and fight effectiveness.The problem ofautomatic aiming and location of critical parts of warship targets by means ofinfrared image sensors are studied in this paper. A real-time processing project is proposed and realized in software. The selecting aimpoint is below the waterlineof the waterline target .Centroid Tracking is applicable to the target image is ofsignificant size of field of view,while frame-to-frame correlation to overflowed.The project can select the aimpoint reliably and ensure the location accuracy re-gardless of the target postures.A satisfactory result is obtained through thesimulation test with 68 frames of infrared images used. |
