摘要

The objective of this paper is to enable CCD camera for area measuring while recording images simultaneously. Based on an established relationship between pixel number and distance in this paper, we can derive the horizontal and vertical length of a targeted object, and subsequently calculate the area covered by the object. Because of the advantages demonstrated, the proposed system can be used for large-area measurements. For example, we can use this system to measure the size of the gap in the embankments during flooding, or the actual area affected by the landslides. Other applications include the surveying of ecosystems by inspecting how widely spread is a certain type of life form. For places which are difficult or impossible to reach, this system can be particularly useful in performing area measurements. Experiments conducted in this paper have indicated that different shooting distances and angles do not affect the measuring results.
