GPS/INS offset in camera calibration
« on: April 21, 2019, 01:14:50 PM »
"GPS/INS offset tab can be used to indicate the position of the GPS/INS unit relatively to the camera center (in the camera coordinate system). " where is the camera center?the lens center?or the cmos‘s center?

Hello Charles,

I think that it can be said that center of perspective is the camera center that is the origin of the coordinate system related to the camera in which the GPS/INS offsets are measured.

Hello Charles,

How to determine that center of perspective,  the length of sensor center plus  focal length?
