The development of unmanned aerial vehicle(UAV)technology has expanded the scope and efficiency of data acquisition.Using UAV to obtain infrared images of heating buildings and establish its three-dimensional thermal infrared model with the help of three-dimensional reconstruction technology can realize a comprehensive,non-invasive,and efficient on-site evaluation of the overall heat loss of heating buildings.This paper proposed an infrared image acquisition method based on UAV technology,which is used for three-dimensional reconstruction to study the heat loss of heating buildings,and determine the optimal flight distance range of 5~20 m and the shooting angle range of infrared camera 0°~45°.It also identified the calculation methods of different flight distances and spatial resolution,and provided feasible experimental methods to obtain high-precision and high-resolution infrared images of building facades for the UAV thermal infrared method and to study the heat loss of buildings.
