AI Infrared Thermal Camera for Temperature Detection

AI Infrared Thermal Camera for Temperature Detection

A thermographic camera (also called a thermal imaging camera/thermal imager) is a unit that develops an image using infrared radiation. Instead of using the normal “400–700” nanometer range of the visible light camera, infrared cameras are able to capture wavelengths from about 1,000 nm (1 μm) to about 14,000 nm (14 μm). The use of developing and studying the aforementioned data that these cameras obtain is called thermography. This data can be used for rapid diagnosis or processed through software for further analysis, precisions, and report dissemination.

The Infrared Fever screening system represents innovative technology in the arena of public safety for managing access control and recognizing early warning signs of illness. The AI thermal cameras involved multi-AI technologies with deep learning can identify non-human heat sources and provide rapid, precise, and secure body temperature detection. The IR thermal camera can be used to detect Elevated Body Temperature, individuals with abnormal temperature in the skin in key areas, especially the corner of the eye and forehead, will be selected for additional screening, which can help to reduce and slow the spread of the virus, especially in pandemic such as COVID-19.

What is AI Infrared Thermal Camera

Unlike the common camera, the image is formed by visible light, the thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process that is called thermal imaging. Artificial intelligence (AI) thermal image processing combines advanced algorithmic technology with machine learning and computer vision to measure the infrared wavelength emanated from 3D object surfaces, and detect the heat given off by an object or a person, and then converts the temperature information into an image in the form of heat. All objects that have a temperature above absolute zero emit heat, and thermal imaging is all about converting that infrared light into electric signals and creating an image using that information.

IR Thermal Camera for Fever ScreenThe incontrovertible awareness of infrared (IR) thermometer technology and its principles is its accurate temperature detection, and it will not be affected by light and can give a clear picture in darkness. When the temperature is gauged by an IR camera the infrared energy emitted by the observed object is translated into an electrical signal in the unit through the optical system of the thermal sensor. The temperature reading of the signal is displayed, usually on a color screen, panel pc, or computer.

The most important factors of temperature are the emissivity, the field of view, the distance to the surface. Emissivity, all objects will reflect, transmit, and emit energy, and only the emitted energy can indicate the temperature of the object. Therefore, all infrared cameras must be adjusted to read only the emitted energy. Measurement errors are usually caused by infrared energy reflected by other light sources. With bi-spectral thermal camera integrated with the AI-enabled temperature detection system technologies, the automatic calibration can adjust the ambient circumstance and temperature, and technology, such as a blackbody calibrator is used as the reference level of radiation thermometry for the emissivity correction, which minimizes the surface temperature error and enables accurate temperature detection. 

IR Thermal Camera Algorithms for Temperature Detection

Due to the irregular shapes of human bodies, and a lack of consistency in body types, Multi-algorithms are used in the IR thermal scanners for temperature detection. In order to circumvent the geometric limitations of the inclusion of useless data in the camera image, a segmentation algorithm may be applied to the selected areas of the body. Segmentation is the process that is performed by separating an object on an image using pixel-level or object-level properties of the pictured object. These image properties can be orientation borders, texture, pixel intensity differences inside certain geometries. Also, an integrated AI thermal camera system provides precise surface temperature detections. The calibration is automated to adjust for the current camera applications, and that sufficiently reduces the surface temperature errors. 

Fever Screen System with Thermal Camera Advantages

With thermal cameras, you will have a distinct performance advantage that will enhance your screening and safety. Thermal cameras can be AI-enhanced, possess machine learning capabilities, use database systems, and have auto-calibration capabilities. AI thermal cameras can scan multiple people at the same time, it does not require any tactile activation (no contact temp registry), and it can come with a plethora of mounting options. With your advanced ability to recognize elevated body temperatures (EBT), you can decrease your risk of spreading disease. Also, other highlighted features are that it is contactless, safe, and provides fast Temperature Detection. Additionally, auto-detect and warnings of abnormal body temperature do accompany thermal camera utilizations with auto-calibration. The AI-enabled thermal camera can be integrated with different hardware platforms, including touch screen panel pc with different sizes, mobile computers, tablet pc, monitor, and more.   

Thermal Imaging Camera Application

With temperature detection applications you will find that there are a plethora of features, benefits, limitations, and applications from these products on the market. There’s manifold of areas where this technology can be used: aerospace, automotive industry, glass industry, chemical industry, electronics, medicine, plastics, and metallurgy. Specifically, the aerospace industry uses thermal cameras for security purposes. The plastics industry uses thermal cameras to help them save money in investing in thermoplastic operations (die casting and extrusion).

IR Thermal temperature detection

For body temperature detection, thermal cameras are widely used as a passage gate entrance access controller in community, office building, hotel, scenic spot, transportation junction or another public service area for fever screening, and it can be equipped in the mobile device, panel pc, computer and more. Additionally AI model applied multi-algorithms can detect if someone is wearing a facial mask or not at the same time detect the temperature very accurately. Thermal cameras do not function well through the glass, steam, dust, smoke, wind, sunlight, etc. It blocks the optical system of the instrument and affects accurate temperature measurement.
