Geometric distortion is an error on an image, between the actual image coordinates and the ideal image coordinates which would be projected theoretically with an ideal sensor and under ideal conditions.
Geometric distortions are classified into internal distortion resulting from the geometry of the sensor, and external distortions resulting from the attitude of the sensor or the shape of the object.
Figure 9.3.1 schematically shows examples of internal distortions, while Figure 9.3.2 shows examples of external distortions.
Table 9.3.1 shows the causes of internal and external distortions and the types of distortions.
