| 摘 要： | "嫦娥一号"(简称CE-1)是中国自主研制并发射的首个月球探测器,卫星搭载的传感器是一个三线阵CCD立体相机,其主要科学目标是获取月球表面三维影像。根据三线阵影像以及月面影像的特点,为了能够得到密集度较高且分布均匀的同名点对,采用了一种基于RPC近似核线约束的影像匹配方法,结果表明基于核线约束的影像匹配方法较之传统二维影像匹配总体耗时短且具有较高的精度与可靠性。

| Abstract: | CE-1 is the first lunar probe satellite,developed and launched by china,which carries Three-Line-Array stereo camera.The main scientific objective is to obtain 3D images of the lunar surface.In order to extract the image conjugate points of high density and uniform distribution,an image matching method based on RPC approximate epipolar geometry constraint was developed and implemented in this paper.It was concluded that the method mentioned in this paper had a higher accuracy and reliability and shorter time-consuming than the traditional image matching methods. |
