Diseño y construcción de un dispositivo electrónico de monitoreo infrarrojo para supervisión de temperatura de niños menores a 3 años.

Abstract

The aim of this graduate research project was the design and construction of an electronic infrared monitoring device for monitoring temperature of children under 3 years of age. The prototype was developed using two cameras to capture images, one for RGB images and the other for thermal images. The system is controlled by the Raspberry Pi 3 microcontroller and the child's measured temperature is displayed through the graphical interface created. If a child’s temperature exceeds the established threshold of greater than 37 degrees Celsius, a text message will be sent to the cell phone of the person responsible for the child, indicating that they have a fever. Several techniques were used to execute system operation and the creation of Source Code, including histogram of oriented gradients (HOG) for human detection, as well as methods such as parallelism, threads and multiprocessing, these techniques are based on Python programming language, which is the chosen software since it allows for the creation of readable codes, saving resources and time. After analyzing the different devices on the market, it was concluded that the implemented device is a child-friendly technological device, which measures physical status and is capable of alerting the person responsible for the infant about their body temperature. After the performance tests and the calculated errors such as the mean absolute error (MAE) and the mean square error (RMSE), it was established that the device meets the necessary requirements. It is recommended that a machine learning algorithm be developed that is capable of determining the region of interest through thermal imaging, as this would reduce the hardware design with the RGB camera not essential.
