As shown in fig. 1, the region between a and B is an observed region, and the observation point is point C. The angle between the field of view of point a and the vertical line passing through point C is called the tilt angle. For a camera, a point a is the nearest end point of an observed region, a point B is the farthest end point of the observed region, object distances between the point a and the point B are greatly different, and an object distance between the point a and the point B is greater than that of the point a, so that generally, in an obtained picture, a resolution is higher than that of the point B, the picture resolution is not uniform, and the whole picture also has a certain geometric distortion.
