The change in photogrammetry from analog to digital means a change from film to CCD sensor and real-time imaging became possible. It can be said that the most remarkable point of this change in photogrammetry is acceleration of real-time imaging. There are many kinds of digital still cameras on the market and these have became useful instruments in real-time imaging for stationary objects.
For moving objects, a video camera is utilized since 30 frames are acquired per second. Video camera means 8mm camera; however, an 8mm camera is an analog camera in spite of the fact that a CCD sensor is used. Thus, a change in video camera from analog to digital means a change from analog tape to digital tape and direct transmission of digital image to a computer.
This paper presents the concept of a digital video camera developed by the authors and shows examples obtained through tests.
