Basic Photogrammetry

Up until now, we investigated two methods to address space resection (DLT, and the Empirical Method). Here, we state the last method that is useful when we have good estimation…

(11 parameter approach) As we saw in the previous section, there are several different ways to address space resection. Perhaps the most practical method is to use the equations of…

Spatial Resection is the problem to find the position and orientation of an image or a set of images in the case that there is an acceptable number of model…

One important application of collinearity equations is in the spatial intersection problem, were we estimate approximate intersection of two 3D lines to find model or ground points for a group…

We may rewrite coplanarity equations by using the following symbols In this case, this equation in a simplified form is This equation can be written in the following vector form…

In coplanarity equations, the goal is to obtain a simple and understandable mathematical form between 1- the coordinates of the photo points in two stereo images and 2- the relative…

Relative orientation is to find the rotations and transitions of an image with respect to a reference photo. So, in the problem of relative orientation, we are always faced with…

Ideal Camera An ideal camera is an empty box with an infinitesimally small opening in one of its faces. In an ideal camera, there is no distortion in the formed…

Transformations play a special role in photogrammetry, so learning the mathematical principles and their calculations helps us better understand and employ photogrammetry tools. A mapping performs the task of transferring…
