This is what the entire world is demanding right now. The solution to measure a human body temperature on a go, because it has to be rapid and precise, contactless, and it must recognize people, their faces and measure temperature of a multiple people at a time. The solution we’re showcasing is provided by Dahua Technology, to whom all the credits go.
The Equipment Used / Mentioned:
- Dahua DH-TPC-BF5421-T Thermal Camera
- Dahua DH-TPC-BF3221-T Thermal Camera
- Dahua DHI-IVSS7008-1I AI Video Recorder
- Dahua DHI-NVR5216-8P-I AI Video Recorder
- Dahua JQ-D70Z Black Body Device
- Dahua RQW026-00 Camera Bracket
- Dahua DH-PFM320D-EN Power Adapter
- Dahua VCT-999 Tripod
The System To Measure Human Temperature and Recognize Faces
Essentially, the system of temperature measurement and human faces recognition consists of:
- Thermal network camera, used specifically for a temperature measurement, which is achieved by dual camera modules setup, featuring one normal camera module and one thermal camera module.
- Next we need a black body calibration device, which essentially, produces and maintains a constant temperature, that is configurable, as a reference point for the thermal camera.
- Except that, we need to recognize, capture, count and store records with people faces and their related body temperature measurements. This role is being performed by an artificially intelligent network video recorder, made for these purposes.
Unfortunately, we couldn’t get one, so this is going to be only a human body temperature measurement demonstration. In addition, you would want to get a tripods and brackets for camera and a black body device, plus what’s left is a power adapter for every listed appliance.
The goal of system is to provide a constant monitoring of a people body temperatures in a crowded and the most hazardous locations like Airports, Train Stations, Hospitals and other critically vital facilities.
The Hardware: Intent
The camera we have is Dahua DH-TPC-BF3221-T Thermal Hybrid Network Camera, that is able to measure human body temperature due to its dual camera setup, consisting of a normal camera module with an infrared LED and thermal camera module altogether in one body, this is what the technology is. The peculiarity is that the camera ignores that the people may wear masks or helmets, it just doesn’t affect the measuring accuracy. It also not measures a temperature of a hot liquids like a tea or coffee that a person could carry. The measuring ability applies to people only, with 30 max. people number in camera’s sight. Of course, there is a certain imprecision probability, but with the black body device it would not exceed more than ± 0.2-0.3 Celsius.
Black Body Calibrator
The task of a black body calibration device, essentially, is to produce and maintain a specific constant temperature, used as a reference point for the thermal camera, and it is adjustable.
On a practice – every time when a person passes through the camera’s measuring sight, the camera correlates a person’s temperature with the temperature of a black body, that produces a constant temperature, while the people temperature will always differ, and this is how the high accuracy is achieved.
On The Practice
To conclude – this is the most highly demanded equipment in a world right now due to the Covid-19 virus enormous propagation speed, while the authorities do what it takes to limit the spread of the virus, and our weapon is data. The more we know about how many of us are infected, the more we control the situation. And among the places of application there are airports, train stations, hospitals and companies that produce the most necessary, vital products. That is why in the Pipl Systems Store we have got all the reviewed today equipment available for you.
