Question

Q. 4. Us ing the principle of collinearity equations, explain why one photo is not adequate to struct the 3D object space (X, Y & Z) of any point? In this case, what is you alternative in order to reconstruct 3D object space? Q. 5. In order to produce up-to-date contour maps, surveying department at Muscat ality plan to conduct an aerial survey project using unmanned aircraft for an area Municip that is approximately 20 km by 80 km. Different scenarios may be executed in order to accomplish the project according to the required specifications depending of camera information and ground control network within the area of interest. S the necessary steps needed for each scenario possible. tate all

Answer 1

4. Collinearity equations are generally a combination of two different equations. It is widely used in photogrammetry. A photo is constructed when the three points- optical centre, object and image point coincide. Thus the two dimensional central protection is constructed. So we can see all the image and object points will be concurrent, thus a set of 2D equations will generate from the central protection. But this one photo will be either on any 2D plane. So no 3D object space can be generated from it.

In order to construct 3D object space, we may create 3 different 2D images on three different 2D planes. When the three axes of central projection will coincide, then it will figure a 3D object space.
