摘　　要：通过在光电设备正前方增加一个标定矩形块,对图像进行一系列的图像处理,得出不同目标的像素值个数,以及标定矩形块的像素值个数;然后将光电图像目标与目标特征数据库中存储的目标通过尺度不变特征变换(SIFT)方法匹配,进而得出目标的实际面积;最后通过比例关系以及目标角度计算出目标距离。In this paper,a calibration rectangular block is set right ahead of the photoelectric equipment,and a series of image processing are performed,then the pixel numbers of different targets and calibration rectangular block are fetched,secondly the photoelectric image targets and targets stored in target feature database are matched through scale-invariant feature transform(SIFT)method,then the actual area of the taget is obtained,finally the target distance is calculated through proportional relation and target angle.

关 键 词：光电图像 目标特征数据库 图像处理 SIFT匹配
