摘要：

In analytical photogrammetry picture point measurements are done with analytical tools or comparators. Measured comparator coordinates are first transformed to picture coordinates and then to object coordinates. Nowadays, direct transformation of digitally captured picture coordinates to object coordinates is ideal. The main advantage of Direct Linear Transformation (DLT) method is that it does not require a calibrated camera or indicator signs. In this study, necessary process steps to be followed in order to calculate camera parameters belonging to a picture pair on a test field are demonstrated on a sample.
