This note shows that when studying geometric properties, a polynomial system is defined as a line field on a projective space such that its singular set has co dimension at least 2.
证明:在研究多项式系统的几何性质时,多项式系统应当定义成射影空间中奇点集之余维数至少为2的线场。
Based on inclusion exclusion principle of set theory, a new algorithm to calculate the whole projective area was put forward to those overlapped complex geometrical objects in any direction.
在此基础上,根据集合论中的包含互斥理论,提出了一种求取多个复杂几何形体在任意方向的投影面积的新算法。
The input of the algorithm is a set of fundamental matrices, and it is not necessary to perform any projective factorization or projective bundle adjustment.
算法中只需输入基础矩阵,不必预先进行任何类型的投影阵分解或投影束校正。
The linear array CCD is used as a sensitive component in a two-dimensional projective photoelectric aim sensor, and the latter is used in the machine tool pre-set instrument.
