ESTABLISHMENT OF CONTROL POINTS FOR DIGITAL PHOTOGRAMMETRY TO ARCHIVE 3D MODEL OF RELICS

摘要

In a surveying of ruins, many hangovers must be quickly archived as digital data. For example, a hundred pieces of hangovers are extracted a day in Dederiyeh Cave, Syria. The detail must be recorded in each change scene for the archeologist. Digital photogrammetry is very efficient for 3D modeling. In this study, control frame is suggested to improve efficiency of digital photogrammetory. Control frame was based on polygon shape. Target of control point was located at apex of the polygon. This control frame will be efficient to setup control point. When the shape of control frame was fixed always, it is not necessary to measure 3D coordinates of all control points. Control frame was tried to design. 134,594 combination of control point were calculated. However, critical combination pattern was not found. Systematic analysis will be required to find optimum special distribution of control point.
