2015/5/12
During recent years the direct sensor orientation with GPS and IMU has gained popularity. These systems allow the determination of
all exterior orientation elements without using ground control point...
FUNDAMENTAL PRINCIPLES OF IMAGE ORIENTATION USING ORTHOGONAL PROJECTION MODEL
orthogonal projection orientation model
<
2015/3/24
The central perspective model is generally used in photogrammetry because of the high reliability, but it has a weak point
that the initial values of orientation parameters are necessary due to the n...
