Paper Abstract

Modern digital technology allows image data transfer over the internet protocol, which provides real time observation and more frequent air quality studies can be carried at multi locational simultaneously. The objective of this study is to evaluate the suitability of using internet protocol camera to transfer image data, and then these data were analysed using a developed algorithm to determine air quality information. The concentrations of particulate matter of size less than 10 micron (PM10) were collected simultaneously with the image data acquisitions. The atmospheric reflectance components were subtracted from their corresponding recorded radiance values for algorithm regression analysis. The proposed algorithm produced high correlation coefficient (R) and low root-mean square error (RMS) values. The efficiency of the present algorithm, in comparison to other forms of algorithm, was also investigated. Based on the values of the correlation coefficient and root-mean-square deviation, the proposed algorithm is considered superior. The accuracy of using IP camera data was compared with a normal digital camera, Kodak DC290 data in this study. This preliminary study gave promising results of air quality studies over USM campus by using internet protocol data.
