ABSTRACT:
This paper is about the evaluation of a digital non-metric reflex camera (Canon D30) for low cost applications in archaeology,
architecture and cultural heritage. At present digital cameras of different geometric qualities are being routinely used for this
purposes. The Canon D30 digital camera is a professional camera with a CMOS sensor of 3.2 Mp. Although camera resolution is
relatively low, compared with more recent amateur cameras, the sensor is slightly smaller in size than conventional 35 mm film
format. The focal length/angle of view conversion factor is approximately 1.6x compared to full frame 35 mm film format. This
property makes very interesting the use of this camera in cultural heritage photogrammetric applications, where both accuracy…
