Abstract
In this paper, a monitoring system based on thermopile array sensors is designed for real-time refreshing of thermograms in a web interface. To address the problem of inconspicuous heat map of the main target caused by the interference of the detection environment and the small temperature difference between the target to be measured and the background, a dynamic color mapping processing scheme is proposed to make the heat map of the main target displayed more clearly by continuously adjusting the contrast between the main target and the background color. The experimental results show that the method can achieve dynamic refreshing of the thermogram through a multi-device browser, the correlation of measurement data is greater than 85% compared to handheld thermometers, and the effective transmission distance is about 30 m in open range, which can effectively enhance the portability and safety of staff during COVID-19 temperature screening.
