What does tilt photogrammetry mean?

Tilt photography is a high-tech developed in the field of international surveying and mapping in recent years. It subverts the limitation that orthophoto images can only be taken from a vertical angle. By carrying multiple sensors on the same flight platform, images are collected from five different angles, one vertical angle and four inclined angles, and users are introduced into the real intuitive world that conforms to human vision. Aerial tilt images can not only truly reflect the ground characteristics, but also embed accurate geographic information, richer image information and more advanced user experience through advanced positioning technology, which greatly expands the application field of remote sensing images and makes the industrial application of remote sensing images deeper. The introduction and application of oblique image technology will also greatly reduce the high cost of three-dimensional city modeling. I hope it helps you.
