Abstract
In Japan, there are many kinds of historical structures which are temples, shrines, private house and so on. Such structures should be observed by landscape architects or researchers due to conservation of landscape assets. With this objective, a software which can be operated as a measurement tool was developed in this investigation. The algorithm of the software is constituted by photogrammetric theory, and assumed the measurement of the historical structures by using a smartphone. The smartphone can be performed taking images and positioning by using GPS. Therefore, a field survey of a historical structure was performed by using only the smartphone, and measurement for the structure was attempted by using the developed software. The traditional photogrammetry was required some ground control points (GCP) or scale factor in measurement space. Nevertheless, the software can be operated by using only taking images and positioning data. As a result, the measurement of the historical structure was realized, and checking accuracy for the measurement was performed. As the further work, measurement accuracy will be improved by resolve of some problems, and user interface of the software will be arranged. These issues should be resolved due to the software will become operational tool for landscape field survey.
