2D Marked Points

2D Marked Points are the point markings made on a photograph. Each 2D Marked Point has one associated Object Point (while each Object Point can have many associated 2D Marked Points, i.e. a marked point for each reference on a photo).

2D Marked Points get referenced to each other to provide PhotoModeler the light ray information it needs to solve the 3D Object Points. See also How Object Points become 3D.
