Minimum Technical Specification For Human Body Temperature Screening System

June 10, 2020 by Uttam Pegu Leave a Comment

Continuing with my previous post about “Not upto the mark”  technical specification for human body screening system in India, I thought I would try to put up specifications which are minimum technical requirement for such systems. It may not be complete and totally exhaustive list, but I think this could be good enough to start with.

  1. It should be dual camera system ie It should have both Thermal Camera and Visual Camera.  Why ? Because : Thermal camera is to measure human body ( face skin) temperature measurement and the visual camera for face detection. Face Detection and Face Recognition are two different thing altogether and should not be confused with one another. Automatic face detection helps identify the person who has high body temperature.
  2. Thermal Camera resolution must be 384X288 Pixels or higher, Why ? While Thermal Cameras with both 80X80 pixels and 160X120 Pixels may be able to detect high body temperature in a human face which is of approx 8-14CM width and 10-17CM in height ( just a general figure) with suitable length, but 384X288 Pixels will out form and offer more flexibility than 160X120 Pixels / 80X80 Pixels ones. Higher resolution Thermal camera require at least 1GBPS Ethernet which may be expensive.

Fever Screening Tender Specification in India

June 2, 2020 by Uttam Pegu Leave a Comment

Recently, I came across a tender specification of which says smart thermal camera with real-time video and body temperature screening system which made me think about body temperature screening systems being sold or deployed in India.

Here is the screenshot of the tender document which outlines the specification of the “Body Temperature Screening System”

Body Temperature Screening

The specification number 1 and 2 makes sense as they are going to be useful for record keeping as well as any future analysis.

Visual Camera in Body Temperature Detection System

Fever Detection System

Almost all “premium version” of elevated body temperature detection system available in the market seems to have both visual and thermal camera in it. I think, main reason to put this visual camera is to identify the person without any human intervention in case he or she is detected with elevated body temperature. While, this argument may not hold true if she is wearing a mask or veil, but still it can give some desirable features to elevated body temperature measurement system

Both the Thermal Camera and the visual camera are places in such a way that their field of view ( FOV ) overlap each other so as to detect the face using visual camera while sensing the temperature using the thermal camera. The visual image will be used to detect a face, then this face area will be identified in the corresponding thermal image. Then the temperature of that area will be measured using the thermal camera. … Continue Reading about Visual Camera in Body Temperature Detection System
