Abstract: In this paper, we propose a new method to measure area using only a single CCD camera in different distances. Two parallel laser beams are established to serve as the basis for horizontal length measurement. A single horizontal scanning line of the CCD image is only required for the area measurement. Based on the pixel numbers between two projected points within a CCD image, which represent the resolution of horizontal length, the actual area can be derived by counting the pixel numbers occupied by the image of the object to be measured on the CCD image. Our research results are merited with quick measurement speed, simple system structures and there will be no necessity to adopt image recognizing or signal analysis techniques to calculate the area from different photographing distances.
