absolute quadric meaning in Chinese
绝对二次曲面
Examples
- In this paper , we prove that given n images captured by a pinhole camera with varying parameters and under general motion , the number of independent kruppa constraints is 5n - 9 , and it is less than that of independent constraints from the absolute quadric by only one
本文首次从代数上严格证明了,摄像机在通常运动下当摄像机的内参数变化时,从n n 3幅图像得到的所有kruppa方程中,只有5n - 9个是独立的 - This one - constraint - less property of the kruppa equations is their inherent deficiency and is independent of camera motion . this deficiency is due to their failure of automatic enforcement of the rank - three - ness on the absolute quadric
从而, kruppa方程的独立个数比基于绝对二次曲面或基于无穷远平面的自标定方程的独立个数少1 ,这是源于kruppa方程不能保证绝对二次曲面的秩为3 ,是由kruppa方程自身的特性决定的,而与摄像机的运动无关。
