Infrared camera

The technology we want to use in our final design is the infrared  camera. This technology can easily scan how many people inside one car. Let me do a simple introduction about the thermographic camera.

A thermographic camera (also called an infrared camera or thermal imaging camera) is a device that forms an image using infrared radiation. Similar to a common camera that forms an image using visible light.  

Generally speaking, the higher an object's temperature is, the more infrared radiation is emitted as black-body radiation. A special camera can detect this radiation in a way similar to the way an ordinary camera detects visible light. It works even in total darkness because ambient light level does not matter. This makes it useful for rescue operations in smoke-filled buildings and underground.

Images from infrared cameras tend to have a single color channel because the cameras generally use a sensor that does not distinguish different wavelengths of infrared radiation. Color cameras require a more complex construction to differentiate wavelength and color has less meaning outside of the normal visible spectrum because the differing wavelengths do not map uniformly into the system of color vision used by humans.
