Abstract
Sometimes it is necessary to measure the length of an object or its distance from a particular location when it is difficult to access the location of the object even not at all accessible. In this paper we proposed an image based measurement technique of such an object and its distance. The technique is very simple, only a digital camera, a wooden bar and three LASERs of intense beam are necessary. Entire measurement is taken ignoring the focal length of the camera but the result provides above 95% accuracy. Such measurement technique; for example is essential for a civil engineer to take approximate measurement before work plan even for a zoologist to measure the size of a wild animal which cannot be caught.
