Standard measurement scale and markers for defining standard measurement scale |
摘要 |
A standard scale used in a photogrammetric measurement system has a polygonal plate having three apexes which are arranged to define a reference plane, where each of the apexes defines a reference point. Another standard scale has a light-guide plate member which has three light-emitting spots for defining reference points. Yet another standard scale has a frame member, and reference-point-forming elements, for defining reference points, arranged on the frame to define a reference plane. A marker used in a photogrammetric measurement system for defining a standard scale has a light-guide plate having a light emitting spot for defining a reference point. Another marker has a polygonal-pyramidal-shaped optical assembly formed from light-guide plates, including a core layer containing fluorescent substances, such that an apex of the optical assembly is defined by an emission of fluorescent radiation therefrom.
