| 摘 要： | 激光雷达主动成像有别于各类被动成像的一个显著优势就是可以直接生成目标的距离图像,与常规光学图像相比距离图像具有一些不同的统计特性,当距离图像中存在多目标时统计直方图具有明显的多峰结构特征.通过对距离图像统计直方图峰值的提取实现了对距离图像的目标提取,利用最小外接矩形拟合及目标距离数据获取了目标的实际尺寸、矩形拟合度等信...

| Abstract: | Active imaging LADAR (Laser Detection And Ranging) stands out from other passive imaging systems for its function of acquiring range image of targets. Compared with traditional optical image, range image has more particular statistical characteristics, it can obviously show multi-peak structures when multiple targets exist in the range image. Target Extraction of range image could be realized by extracting peaks of its stat-histogram; and targets could be classified by the size and rectangle degree obtained by the use of minimum enclosing rectangle. Processing a real range image by using this method has obtained the anticipated result. |

| Keywords: | LADAR range image histogram peak detection minimum enclosing rectangle object classification |
