This paper treats parameter estimation and performance bounds for multi-spectral model-based non-contact temperature measurement techniques. Based on Planck's law and different models for the unknown emissivity, different signal models for the interrogation results of a hot object with a multispectral camera are discussed. Based on these models, estimators and Cramér-Rao lower bounds for the unknown...
In this paper we present a proof of concept for non-contact extraction of vital signs using RGB and thermal images obtained from a smart phone. Using our method, heart rate, respiratory rate and forehead temperature can be measured concurrently. Face detection and tracking is leveraged in order to allow natural motion of patients. Heart rate is estimated via processing of visible band RGB video using...
This paper describes the process of the development and improvement of the altitude and vertical velocity estimation algorithm. The previous method was developed by authors two years back. After a diagnosis of pressure temperature drift caused by the main IMU, the additional barometric sensor was introduced. Based on readings from this reference component, three main modifications were developed to...
In this paper, we study a method for non-contact measurement of human oral breathing. First, we propose a method for estimation of the state of oral airflow strength based on the change in temperature of oral cavity. Here, we suppose that the strength of oral breathing can be classified as four kinds of state. Next, we conducted simulation experiments to evaluate our proposed method using facial thermal...
The calculation of energy efficiency of buildings has carried out based of the measurements (external and internal building temperature, emissivity of the outer and inner surfaces of the wall) and the appropriate construction parameters. The aim of this paper is to show the impact of changes of emissivity on the accuracy of the temperature of building materials and heat flux construction. The experiment...
A FLIR SC5000 IR thermovision camera was used for analyzing the temperature distribution on the gold surface of the test devices (Schottky diode). The goal was to estimate the values of the temperature in various areas on the surface of the test device. In order to increase the emissivity, the surface was covered with a spray paint, a solution allowing to obtaining better estimations of the surface...
In many mobile robot application, navigation is a critical issues. This paper deals with the localization and building problem in an unknown indoor environment. We propose an exploration based on the use of the sensorial data provided by one CCD camera and odometer system. In this paper, the first part of our study is linked to the problem of Vehicle Model and the algorithm model. The second part...
