Photogrammetry includes several parts

Over the article summarizes the basic idea of photogrammetry technology and means of implementation.

Photogrammetry is to complete the measurement through photography, its task is to get the actual three-dimensional coordinates of the corresponding target from the two-dimensional coordinates of the image point, to complete the measurement, and then processed to have a map, three-dimensional reconstruction and other applications.

The main ideas and methods of traditional photogrammetry are introduced below. Since the geometric part of computer vision and photogrammetry are solving the same problems, and since computer vision is clearly a much more widely used discipline nowadays, I will try to link the two disciplines by briefly describing the corresponding chapter in computer vision after each chapter.

Still a student, my level is limited, so please bear with me.
