Understanding JDBC Metadata By Kyle Brown, Knowledge Systems Corporation In the previous article in this series, we stopped in the middle of building a set of classes that comprise a vendor-indepe
不同像平面坐标系下Brown畸变系数转换 记 u , v u,v u,v为像素为单位的坐标,f为焦距,单位也是像素。 记 x , y x,y x,y为理想坐标。本文推导两种情况下的Brown畸变系数转换关系: 相同坐标系定义、不同的坐标单位(像素坐标与归一化坐标)的畸变系数关系坐标系原点相同、y轴方向相反的坐标系之间畸变系数关系 像素坐标与归一化坐标的畸变系数的关系推导 像素为单位的畸变
