Abstract
A highly accurate and low-cost mobile platform for multiple object temperature measurement in 3D coordinate positions is introduced. The key idea relies on not only a combination of a 3D optical depth sensor and the 2D infrared thermal imager but also a determined distant-dependent compensation model. As a result, a cost-effective yet wider (>100.0∘C) temperature measurement range under the fluctuation of working distant shift is realized with a low standard deviation of 0.16°C at the working distance of 1.0 m. Accurate temperature measurement at different positions of objects along the suitable working distance is also demonstrated.
