我在用isprs.ign.fr上下载的带标定参数的航空图像时,对给出的标定参数有些不解。标定参数如下:
Here is detailed example of one of these files (in green: internal calibration parameters, in red: external calibration parameters)0 -> type of distortion modelisation (0 : distorsion-free ; 1 : grids; 2 : radial polynom)
0 -> modelisation of athmospheric refraction (0: no ; 1: yes)
117 110 107 110 111 119 110 0 -> char[8] the name of the camera (in this particulare case: "U N K O W N")
23 5 2001 11 4 33 -> day month year hour minut second of the frame acquisition
44299 -> mean elevation of the ground (in mm)
595489745 243440215 -> Lambert coordinates of the center of the local tangent reference frame to the survey (in mm)
1 -> Lambert area
1318659 626485 1439146 -> Perspective center in ground local coordinates (en mm)
5746267 -> Focal length (*10^3 pixels)
-189837937 981791672 6831520 -> first line of the rotation matrix passing from image to object space (*10^9)
981789202 189879137 -5989650 -> second line of the rotation matrix
-7177751 5570050 -999958726 -> third line of the rotation matrix
9000 9000 -> pixel size in the focal plane (*10^3, in microns)
1180 1067 -> image size: row, line (in pixels)
-883000 -501000 -> Principal point of autocollimation (*10^3, in pixels)其中主点(红色部分)参数的位置太不合理了。不知道有哪位大侠能帮忙解释一下呀
