Simple Correction Methods of Infrared Thermography for Building Exterior Surfaces

摘要: AbstractThere is a need to improve the accuracy of infrared thermography for measuring temperature distribution building exterior surfaces. Thermography useful ventilation and thermal analysis, as well understanding city urban heat island phenomenon. The key in correcting images quantify accurately reflected contribution surrounding surfaces that atmosphere. Two new methods are proposed here measured by thermography. first simplified version aluminium mirror method developed Datcu et al (2005). second temperature-based using surface temperatures at one or more points on same surface. We present two series specially designed experiments evaluate other commonly used/default methods. can be used effectively cor...
