Abstract:
Continuous and on the fly heat monitoring in industries like manufacturing and chemical is of compelling research nowadays. The recent advancement in IR thermal sensors unfold the possibilities to fuse the thermal information with other low cost sensor (like optical camera) to perform area or volumetric heat measurement of any heated object. Recent development of affordable handheld mobile thermal sensor as a smart-phone attachment by FLIR encouraged the researcher to develop thermal monitoring system as smart-phone application. In pursuit of this goal we present a light weight system with a combination of optical and thermal sensors to create a thermal dense 3D model along with area/volume measurement of the heated zones using smart-phone. Our proposed pipeline captures RGB and thermal images simultaneously using FLIR thermal attachment. Estimates the poses for RGB and depth images, 3D models are generated by tracking the features from RGB images. Back-projection is used to colour t
he 3D points to represent both in RGB as well as an estimated surface temperature. The final output of the system is the detected hot region with area/volumetric measurement. Experimental results demonstrate that the cost effective system is capable to measure hot areas accurately and usable in everyday life.
