The analysis of technological scheme for creation of façade plans of architectural monuments which are subject restoration by a digital survey and laser scanning is presented. Attention is accented on insufficiency of information at the use only of laser scanning. At the same time, there is possibility not only to get necessary information for the further architectural measuring but also increase accuracy of obtaining co-ordinates of object points due to the redundant amount of control points at joint treatment of processing of survey and scanning.
The analysis of a priori accuracy of determine spatial co-ordinates of facade plans of architectural constructions that made by a digital survey and laser scanning and which are subject restoration is presented. The attention is focused on influence of the investigated errors of laser scanning and digital camera.
