THE EXAMPLE OF USING THE XIAOMI CAMERAS IN INVENTORY OF MONUMENTAL OBJECTS - FIRST RESULTS

At present, digital documentation recorded in the form of raster or vector files is the obligatory way of inventorying historical objects. Today, photogrammetry is becoming more and more popular and is becoming the standard of documentation in many projects involving the recording of all possible spatial data on landscape, architecture, or even single objects. Low-cost sensors allow for the creation of reliable and accurate three-dimensional models of investigated objects. This paper presents the results of a comparison between the outcomes obtained when using three sources of image: low-cost Xiaomi cameras, a full-frame camera (Canon 5D Mark II) and middle-frame camera (Hasselblad-Hd4). In order to check how the results obtained from the two sensors differ the following parameters were analysed: the accuracy of the orientation of the ground level photos on the control and check points, the distribution of appointed distortion in the self-calibration process, the flatness of the walls, the discrepancies between point clouds from the low-cost cameras and references data. The results presented below are a result of co-operation of researchers from three institutions: the Systems Research Institute PAS, The Department of Geodesy and Cartography at the Warsaw University of Technology and the National Museum in Warsaw.
