ABSTRACT
When the position and inclination (exterior orientation element) of a camera at the time of photography are searched for
by conventional photogrammetry, the standard point ground coordinates must be known, and time and labor are needed
for the survey or installation work. In recent years, development of the device which determines the position and
inclination of a camera at the time of photography using GPS and the fiber optical gyroscope has been achieved. However,
the price of such device is also high and it is hard for it to be used widely generally. This study is a fundamental study in
which the accelerometer and the inexpensive vibration gyroscope were used, and the information about the position and
inclination of a camera at the time of photography was acquired, and was examined in connection with the application to
the photogrammetry of an inertial navigation system. The camera used was a general single lens reflex camera. By this
experiment, we could get various basic data required in order to make it apply to the photogrammetry. Moreover, by
searching for the position and inclination of a camera with the accelerometer and the vibration gyroscope, and treating as
an exterior orientation element of a camera, simple photogrammetry could be performed. Consequently, rough form or
position relating to a photographic subject could be expressed. The apparatus used in this experiment has also
accomplished technical progress fast every day, and is considered to be able to give more accurate results.
