Single view methodology has been a long-standing issue of extracting metric information from a single image in the relevant disciplines. To perform metric measurements on a single image, two methods, which are based on identifying vanishing points (VPs), were employed in the study. One of the two methods is based on the cross ratio and VPs computation and the other integrates robust statistical estimators and close range techniques in a multidisciplinary concept. The estimation of object distance from a single image taken in an outdoor environment was the main concern for a practical application in the study. As the main concern of the study, accuracy analysis of distance measurements was performed to compare the performance of two techniques and experimental results are presented.
