The method proposed in the paper calculates the relative position and attitude using known geometry information of target feature points in object frame and their image points ' coordinates in image plane based on perspective theory. 该方法利用目标特征点在物体坐标系中的空间坐标及其在像平面上成像点的图像坐标,根据透视成像理论,采用针孔模型解算出目标航天器与图像传感器的相对状态。
The world hypostases ( that is, self-similarity of the part and the whole in a system ) is revealed with fractal theory which is known as the geometry of nature. 分形理论揭示了世界的本质即部分与整体的自相似性,它被誉为大自然的几何学。
From, it is known that Lyra geometry representation of metric defect has specific superiority. 可知,度量缺陷的Lyra几何表象具有特殊的优越性。
Fractal geometry is one of the best mathematical tools for people to describe and simulate various beautiful natural scenes, thus being known as the natural geometry. 分形几何为人类描述和模拟大自然中的千姿百态的自然景物提供了一种可行的数学工具。
This paper presents a simple method with which complex calculating can be avoided and next unknown node coordinate can be found from known one by using simple geometry relationship. 文章提出了一个用直线逼近渐开线的简易计算方法,这个方法避免了复杂的运算。
