中文摘要： 在红外热成像探测中,待测目标大都包括部分光学厚表面或处于光学厚材料构成的外界障碍之中,使得目标体热像探测成为一个难题.本项目提出一种基于光纤束层析及红外多目视觉的融合视觉目标探测方法,该方法拟采用红外多目视觉重构目标表面光学薄区域及光学厚区域边界特征点空间坐标及通带辐射强度.对于光学厚区域保留多目视觉通带辐射强度重构结果;对于光学薄区域利用光纤束层析,以多目视觉重构出的区域边界点及通带辐射强度为约束,结合有限视角及有遮挡物的光学层析算法,基于信息融合理论进行目标内部通带辐射强度及相应温度分布等红外信息的三维重建.项目进行红外融合视觉的理论、算法及实验研究,并初步解决其在目标立体热成像应用中的关键问题。项目的研究在工业、军事、航空等领域具有重要科学意义.其成果可用于构建红外体热像探测设备,通过选择以不同温度辐射峰值波长为中心的通带,可满足高、中、低温各种红外目标的空间探测需求.

英文摘要： In the field of infrared thermal testing, the targets to be detected usually have surfaces partly consisting of optical thick region or are enclosed by the outside obstacles of optical thick material;therefore the volume thermography for targets becomes a problem . The project proposes a fusion vision testing approach for target, which is based on optical fiber bundle tomography (OFBT) and infrared multi-view vision (MV). The approach utilizes infrared MV to reconstitute the spatial coordinates and passband radiation intensity of the boundary points between the optical thick regions and the optical thin regions of the target's surface. The reconstituted passband radiation intensity distribution of the optical thick regions is reserved; for the optical thin regions, we reconstruct the three-dimensional distributions of inner passband radiation intensity and temperature based on OFBT and the theroy of information fusion, which combines an algorithm under the limited-view and obstacle conditions with a restriction of the coordinates and passband intensity of the bundary points reconstituted by infrared MV. The poject makes the researches on theory, algorithms and experiments of the infrared fusion vision (IFV), and solves the key problems of the applications of IFV to the three-dimensional thermography.
