摘要
激光成像目标模拟装置是激光雷达半实物仿真系统中的关键部件,其关键技术之一是目标建模。研究了激光成像目标的建模方法,以坐标变换理论为基础建立了目标模型,并搭建实验装置对模型进行验证。通过对不同视角下扫描的部分目标信息进行数据配准,得到目标的整体信息,然后根据视点坐标变换关系,可以在空间中任意视点获得目标的信息,以供图像生成系统生成图像。实验结果与理论值相似度高,验证了建模的正确性,为激光雷达回波目标模拟器获取目标信息提供了一条可行的途径。
Abstract
LADAR target simulator is the key component of the HWIL system for LADAR,which is designed to simulate the LADAR return projection. One of the key technologies of target simulator is object modeling. The method of object modeling was performed and mathematic models were given based on coordinate transformation. The overall information of target was obtained through data registration on the part of the target information from different angles of scanning. Then according to the viewpoint of coordinate transformation, the target information was obtained by arbitrary viewpoint in the space, which was provided for image generation system to generate an image. Theoretical results agree well with the values measured experimentally. Therefore, the accuracy of modeling was verified by experiment. This method can provide a feasible way for LADAR target simulator to acquire the information of the target.
