1. What is tilt photography?
Tilting photography technology is a high-tech developed in the field of international mapping and remote sensing in recent years. It is equipped with multiple sensors on the same flight platform (as shown in Figure 1, the current five-lens camera is used), which is different from vertical and tilt. Capture images at angles to obtain more complete and accurate information on ground objects. The image acquired by the vertical ground angle is called the positive film (a set of images), and the image taken by the lens at a certain angle to the ground is called the oblique film (four sets of images).
