This research aims to explore the potential of low cost video camera for 3D
modelling of large historical monuments. As we know, photos extraction is a fundamental
issue in any photogrammetric project. In fact, cost and time are dependent on photo
extraction method. Usually, photos are taken one by one assuring that every object point is
on two photos at least. This operation is time consuming in large scenes modelling. In the
other hand, video record is a simple operation and requires short time comparing to
traditional photo shooting. Then, it will be useful to suggest an approach to use video
recordings as a source of photos required for 3D modelling.
In the present study, we will evaluate the capability of two video cameras. The first
one is a commercial independent camera and the second is associated with a mobile
phone in the extraction of photos required for 3D modelling of a relatively large objects. It
should be noted that the resolution of video frames in mobile phone cameras (comparing to
professional ones) is less than the resolution of ordinary photos. Hence, 3D models
resulting using these frames will be good for applications that don’t require high precision.
