Bosch has launched a human skin temperature detection solution that features built-in Artificial Intelligence (AI). The intelligent solution assists businesses to react to and predict possible infections. Data from the Human Skin Temperature Detection solution from Bosch provides actionable insights that can minimise virus spread by accurately identifying people with elevated skin temperature at checkpoints in office buildings, manufacturing plants and airports.
During the COVID-19 pandemic, businesses need to stay open to serve customers, generate revenue, pay employee salaries and contribute to the economy while keeping people safe. The Human Skin Temperature Detection solution from Bosch is a contactless screening tool that can scan employees, customers, visitors and contractors for elevated skin temperature. By leveraging critical data, business owners and security operators can take the right predictive measures to safeguard people’s health.
Bosch offers Intelligent Video Analytics, a form of AI, as standard in video security cameras. This data-driven approach, coupled with its ability to build high-quality hardware platforms, has enabled Bosch to swiftly develop a solution that detects elevated skin temperatures and offers businesses an option to reduce disruption as the coronavirus pandemic persists.
The camera’s thermal module is precise and has a radiometric accuracy of +/- 0.5 °C / 0.9 °F, meaning the Human Skin Temperature Detection solution is among the devices that comply with the stringent norms of the FDA’s April 2020 Emergency Use Authorisation (EUA) Enforcement Policy for Telethermographic Systems guidelines and has been tested by an independent third-party lab for accuracy, stability and drift per International Electrotechnical Commission IEC80601-2-59:2017 test setup.
The solution provides a contactless measurement within a range of 2.5-4.5 metres. It also contributes to the maintenance of proper physical distancing in areas where people must pass through a checkpoint, such as in airports, commercial buildings or manufacturing plants.
TheHuman Skin Temperature Detection solution is offered as a kit that contains a DINION IP thermal 9000 RM camera combined with a smart VIDEOJET decoder 7000 that also acts as a direct monitor output, a temperature reference device (blackbody), a special control keyboard and specific software that helps to detect anomalies in human skin temperature.
The camera’s built-in AI or Intelligent Video Analytics detects faces in the field of view, and the decoder’s embedded thermal algorithm will locate the hotspots on the face. For reliable screening, individuals need to face the camera, remove glasses, hats and other head and face coverings, and remain still. The solution will quickly detect multiple facial hotspots and indicate if an individual has an elevated skin temperature. The system has an intuitive interface allowing operators to access temperature alarms, temperature histograms, quick snapshot replay and alarm threshold configurations via a USB keyboard, without the need for an additional computer or software.
Safeguarding people’s health involves processing sensitive data. The Human Skin Temperature Detection solution from Bosch offers a special GDPR compliant public self-service mode. This self-service mode will cover the person’s face and hide the screen’s absolute temperature data. By default, the decoder will automatically erase stored historical data after four hours to ensure the latest data is used for reference, and sensitive data is not unnecessarily retained.
Depending on the application, operators can choose from three alarm profiles to achieve high screening accuracy: absolute, relative or automatic alarm thresholds. In a controlled environment, such as inside a building, operators can use the absolute alarm threshold. This profile measures the absolute skin temperature of the hottest spots on the face and triggers an alert when the preconfigured threshold is reached or exceeded. When skin temperature may vary due to environmental conditions, like air temperature, operators can apply the relative alarm threshold. With this profile, the alarm temperature threshold is based on the average temperature of multiple persons plus x degrees. For applications that need to scan large numbers of people daily, operators can choose the automatic alarm threshold. This profile provides an alarm whenever the skin temperature is within a configurable fraction (alarm ratio) of the hottest previously observed values. The alarm threshold is automatically based on the rolling average of the population previously observed. All profiles offer either manual or automatic face detection.
The solution’s built-in AI filters possible false triggers caused by heat sources like a cup of coffee. The system continuously monitors all temperature data (both historical and current). If there are too many deviations, a new threshold is estimated so that an operator can update system settings accordingly.
The Bosch Human Skin Temperature Detection solution provides an accurate tool that leverages critical data, assisting business owners and security operators to take the right predictive measures to safeguard people’s health and help businesses stay open.
