建筑无人机红外遥感测温方法研究

Research on UAV Infrared Remote Sensing Temperature Measurement Method for Building

以某位于寒冷气候区B区住宅建筑为例,基于红外遥感测温原理,开展对建筑的热环境监测实验。提出一种基于无人机红外遥感测温的室温监测方法,给出测温原理及评价标准,提出2种室温计算方法。确定基准房间的选择原则:选定南向、面积较大房间作为基准房间。确定基准区域的选择原则:每层设置1个基准区域。在2种室温计算方法中,在不增加温度传感器数量的条件下,方法2误差绝对值的平均值为0.8℃,可以提高红外遥感测温精度并减小误差绝对值离散程度。

Taking a residential building located in Zone B of a cold climate zone as an example,based on the principle of infrared remote sensing temperature measurement,the thermal environment monitoring experiment of the building is carried out.A room temperature monitoring method based on UAV infrared remote sensing temperature measurement is proposed.The principle and evaluation criteria of temperature measurement are given.Two calculation methods of room temperature are proposed.The selection principle for determining the benchmark room is to select a room facing south with a larger area as the benchmark room.The selection principle for determining the benchmark areas is to set one benchmark area for each layer.Among the two room temperature calculation methods,without increasing the number of temperature sensors,the average absolute error value of the method 2 is 0.8℃,which can improve the accuracy of infrared remote sensing temperature measurement and reduce the degree of absolute error dispersion.
