Query: A Cloud-Edge-Terminal Collaborative System for Temperature Measurement
  in COVID-19 Prevention   To prevent the spread of coronavirus disease 2019 (COVID-19), preliminary
temperature measurement and mask detection in public areas are conducted.
However, the existing temperature measurement methods face the problems of
safety and deployment. In this paper, to realize safe and accurate temperature
measurement even when a person's face is partially obscured, we propose a
cloud-edge-terminal collaborative system with a lightweight infrared
temperature measurement model. A binocular camera with an RGB lens and a
thermal lens is utilized to simultaneously capture image pairs. Then, a mobile
detection model based on a multi-task cascaded convolutional network (MTCNN) is
proposed to realize face alignment and mask detection on the RGB images. For
accurate temperature measurement, we transform the facial landmarks on the RGB
images to the thermal images by an affine transformation and select a more
accurate temperature measurement area on the forehead. The collected
information is uploaded to the cloud in real time for COVID-19 prevention.
Experiments show that the detection model is only 6.1M and the average
detection speed is 257ms. At a distance of 1m, the error of indoor temperature
measurement is about 3%. That is, the proposed system can realize real-time
temperature measurement in public areas.
