The Covid-19 pandemic created an urgency to develop and deploy solutions such as Thermal cameras for mass fever detection at public places to mitigate the spread of the virus. Hence, there was a need for a vendor with rich capabilities in camera design, calibration, system integration along with AI capabilities.
One of the customers wanted to design and develop a high end AI- driven thermal camera that can be placed at the entry of public places such as offices, malls, airports etc. for mass fever detection, detecting sick and infectious people and other use cases such as social distancing, mask detection, etc.
Selection of optical Camera: Achieving HDR feature (>100Db) with 1080p/ 4K image sensor.
Selection of IR cut filter and narrow FOV lens.
Selection of Thermal Camera: The selection of camera bridge was challenging, hence VVDN used crosslink FPGA to convert 14 bits CMOP to MIPI-CSI interface.
Selection of Audio DSP: Hardware complexity (placement of mic, angle of arrival, reduction of noise) for different applications.
Software: Creating the APIs for various thermal camera parameters.
Integration of all the modules (Thermal camera, Optical camera, audio DSP, SSD, Wi-Fi, Bluetooth, LTE, Display port, Type C power delivery, USB hub, POE, etc.)
Taking the requirement from the customer, VVDN designed, developed and manufactured the thermal camera that can be used for high-accuracy, high-throughput, AI-driven mass fever detection systems. With an ultra-high definition optical imager, as well as its high-accuracy radiometric thermal imager, the camera can measure body temperature with high accuracy. The camera developed by VVDN has a supercomputer-grade AI Accelerator as well as different sensors that can also be used to run advanced AI-driven detection such as detecting people coughing, sneezing, etc depending on the use case and requirements. VVDN also developed one blackbody calibrator that can be paired with the camera simply via bluetooth or ethernet for highest precision and measurement accuracy.
The cameras have connectivity through ethernet,LTE/4G,and Wi-Fi. As the subject walks through the screening area, the camera captures the temperature and indicates the difference between the subject’s and the black body’s predetermined temperature. If the high fever is detected, the camera sends the notification over the cloud and management console to take necessary action.
