Principle of Body Temperature Screening Smart Camera

2021-10-14

Body Temperature Screening Smart Camera contains two major functions, one is imaging and the other is temperature measurement.

Let me talk about the principle of temperature measurement. Objects above absolute zero will emit infrared radiation energy, and the temperature is proportional to the infrared wavelength.

The imaging principle is that the light reflected by the human body is converted into a raw image through the photoelectric sensor of the camera, and each pixel contains the three primary color components of rgb. This information is processed by the CPU, transmitted to the framebuffer of the monitor, and displayed on the monitor.

The two functions are superimposed and used to mark the body temperature on the basis of imaging. As you can see, a camera, connected to a monitor, can display a portrait on the screen and mark the body temperature of the human body.
