Object Points are one of the most important items in PhotoModeler. Most projects will contain Object Points. An Object Point is a 3D location (X,Y,Z).
Object Points are central to camera station orientation and overall processing. The only type of project that may not have any Object Points is a single photo constrained project using Edges.
Object Points are created by placing Marked Points on Photographs. These Marked Points are then referenced together (in a multi-photo points-based project) to define the 3D location of the Object Point.
There are three classes of Object Point:
• Normal Object Point: created during marking. Referred to as "Object Point" and sometimes "3D Point" in the User Manual.
• Surface Draw Point: created during Surface Drawing for obtaining a 3D location in a single photograph by placing it on a 3D surface.
• Control Point: imported and marked through the Imports and Coordinate Systems Pane. A user defined XYZ location that aids in orientation, scaling, and improving accuracy.
