Abstract

Automatic apparatus for the measurement of human body temperature using an IR temperature sensor and the video camera to guide the direction of the measurement. The invention consists in the incorporation of the automatic detection of human faces in the field of vision of the camera that, based on this data, changes the direction of the sensor by IR to measure the temperature and thus obtains the precise parameter of the body temperature of the person within the field of view of the camera. As a result, high-resolution thermal imaging cameras could be dispensed with in the field of automatic control of human body temperature. This invention can be widely used for mass monitoring of human body temperature in order to detect people with fever. (Machine-translation by Google Translate, not legally binding)

DESCRIPCIÓNDESCRIPTION

Aparato automático para medición sin contacto de la temperatura corporal humana mediante sensor de temperatura por infrarrojos (IR), con la función de cambiar la dirección del sensor y de la cámara para establecer la direccionalidad de la mediciónAutomatic device for non-contact measurement of human body temperature by infrared (IR) temperature sensor, with the function of changing the direction of the sensor and the camera to establish the directionality of the measurement

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se encuadra en el ámbito de sistemas de control automatizado de la temperatura corporal humana y detección de personas con fiebre.The present invention falls within the scope of automated control systems for human body temperature and detection of people with fever.

El objeto principal de la presente invención es el aparato que realiza la medición precisa, rápida y fiable de la temperatura corporal humana, sin contacto y utilizando sensor de temperatura por IR con la función de su guiado automático sobre la persona objeto de control de temperatura.The main object of the present invention is the apparatus that performs the precise, fast and reliable measurement of human body temperature, without contact and using an IR temperature sensor with the function of its automatic guidance on the person subject to temperature control.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

La fiebre es un síntoma que muchas veces indica la presencia en el cuerpo humano de una infección bacteriana o viral. Por consiguiente, la medición de la temperatura corporal humana se considera un método estándar para detectar la presencia de la infección bacteriana o viral. Los servicios de vigilancia epidemiológica a menudo implementan controles masivos de temperatura de personas que desean acceder a los lugares concurridos durante brotes de enfermedades o epidemias.Fever is a symptom that often indicates the presence in the human body of a bacterial or viral infection. Therefore, measurement of human body temperature is considered a standard method to detect the presence of bacterial or viral infection. Epidemiological surveillance services often implement massive temperature controls of people who want to access crowded places during outbreaks of disease or epidemics.

Entretanto, es muy importante no obstaculizar el flujo de personas ni crear aglomeraciones que podrían aumentar el riesgo de contagio.In the meantime, it is very important not to obstruct the flow of people or create crowds that could increase the risk of contagion.

Actualmente, este tipo de control se realiza a menudo por medición manual de la temperatura corporal de todos los individuos en los puntos de acceso. Esto aumenta el riesgo de propagación de la enfermedad, ya que el empleado de control entra en contacto con gran número de personas a lo largo de su jornada laboral. También se utilizan con frecuencia las cámaras termográficas que son muy costosas y tienen baja precisión de medición. Currently, this type of monitoring is often performed by manual measurement of the body temperature of all individuals at the access points. This increases the risk of spreading the disease, since the control employee comes into contact with large numbers of people throughout his working day. Thermal imaging cameras are also frequently used, which are very expensive and have low measurement precision.

Otra solución que ofrecen los fabricantes de las cámaras termográficas son los sistemas que analizan la imagen térmica obtenida por la cámara, complementan las imágenes termográficas con los datos de temperatura corporal de cada individuo y alertan al detectar a personas con temperatura elevada (por ejemplo, SEEK SCAN™ de la empresa SEEK thermal o Telpo Smart de Telpo).Another solution offered by the manufacturers of thermal imaging cameras are systems that analyze the thermal image obtained by the camera, complement the thermal images with the body temperature data of each individual and alert when detecting people with high temperature (for example, SEEK SCAN ™ from SEEK thermal or Telpo Smart from Telpo).

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

Nuestra solución permite prescindir de las costosas cámaras termográficas de alta resolución usando solo sensor de temperatura por IR con el campo de visión reducido.Our solution allows you to do without expensive high resolution thermal imaging cameras by using only IR temperature sensor with reduced field of view.

En lugar de medir la temperatura en un campo amplio de visión con la cámara termográfica de alta resolución que realiza el escaneo para detectar a personas y medir su temperatura corporal, sugerimos utilizar la imagen de la cámara para determinar la posición de los individuos con respecto al aparato y guiar el sensor de temperatura por IR al punto del espacio correspondiente para medir la temperatura corporal de los individuos en el campo de visión de la cámara.Instead of measuring temperature in a wide field of view with the high resolution thermal imaging camera that scans to detect people and measure their body temperature, we suggest using the camera image to determine the position of individuals relative to the apparatus and guide the IR temperature sensor to the corresponding space point to measure the body temperature of individuals in the field of view of the camera.

Esto permite reducir considerablemente el precio del sistema y aumentar la precisión de la medición.This makes it possible to considerably reduce the price of the system and increase the precision of the measurement.

El sistema está compuesto por cámara (6), mecanismo para variar la dirección de medición de la temperatura y del sensor de temperatura por IR (5) y computadora (7) que procesa la imagen de la cámara y dirige el sensor hacia el punto requerido. Fig.1The system is composed of a camera (6), a mechanism to vary the direction of temperature measurement and the IR temperature sensor (5) and a computer (7) that processes the camera image and directs the sensor to the required point. . Fig. 1

El aparato funciona del siguiente modo: se analiza la imagen en el campo de visión (1) de la cámara (6), se detecta la presencia y la posición de la cara (3) de la persona (2) mediante uno de los algoritmos que son de conocimiento público, y acto seguido, se cambia la dirección del sensor de la temperatura (4) para medir la temperatura corporal de esta persona. Fig. 1The device works as follows: the image is analyzed in the field of view (1) of the camera (6), the presence and position of the person's face (3) are detected (2) using one of the algorithms that are public knowledge, and immediately afterwards, the direction of the temperature sensor (4) is changed to measure the body temperature of this person. Fig. 1

Por lo tanto, una importante particularidad de la invención es la medición de la temperatura corporal mediante sensor de temperatura por IR con la posibilidad de guiado automático de la dirección de la medición. La dirección de la medición requerida se calcula en base a procesamiento de la imagen de la cámara en la cual se detecta el posicionamiento de la persona con relación a este aparato.Therefore, an important particularity of the invention is the measurement of body temperature by means of an IR temperature sensor with the possibility of automatic guidance of the measurement direction. The direction of the required measurement is calculated based on image processing of the camera in which the positioning of the person relative to this apparatus is detected.

La dirección del sensor por IR para la medición de la temperatura puede ser modificada usando cualquier método, como, por ejemplo, un sistema de espejos, lentes, giro del sensor, etc.The direction of the IR sensor for temperature measurement can be changed using any method, such as a system of mirrors, lenses, rotating the sensor, etc.

La cámara puede ser fija; también puede mover su campo de visión de forma independiente al sensor de la temperatura o en conjunto con este sensor.The camera can be fixed; You can also move your field of view independently of the temperature sensor or in conjunction with this sensor.
