The authors are studying the analysis of color airial photographs by using the Ube Tech. College Picture Information Processing System, U-PIPS. A lot of results of this research they reported were mainly taken out of chromatic characteristics in a photograph. In order to improve region segmentation abilities, they are willing to get height or depth informations concerning with the object. It is necessary for this to process two different photographs, in these photographs, same objects are taken at several centi-meters apart i.e., stereo-photographs. As the first step in this scheme, they investigated stereo-photographs of building-brocks because of its simplicity in shape. Two photographs were taken at about 20 centi-meters apart. Next co-ordinates of all vertexes were measured individually in these photographs. Dimensions of building-blocks were calculated from measured coordinates and compared with actual dimensions. There were small defferences in these dimensions. After some investigations it was found that these errors were mainly caused by measuring errors of coordinates of vertexes.
