Thermal imaging amends overtness of the objects in a dark environment by identifying the objects infrared radiation and then engendering an image predicated on temperature information. Near infrared illumination, low light imaging is withal most commonly used night vision technologies. Contrary to these two methods thermal imaging works in environments without any light. Thermal imaging can also penetrate obscurants such as smoke, fog and haze.
In thermal imaging all objects emanate heat as a element of their temperature. The warmth radiated by question is kenned as its heat signature. As a rule one can verbalize, the sultrier a Question is the more radiation it emanates. A thermal camera is basically a warmth sensor that is fit for recognizing infinitesimal contrasts in temperature. The contrivance accumulates the heat from objects in the scene and engenders an image predicated on information about the temperature differences. Since items are rarely an indistinguishable temperature

Due to the image resolution and better quality and less cost there will be more demand to thermal imagery. Few applications are given below:
Agriculture: Estimating water stress in crops, Planning irrigation scheduling, Disease and pathogen recognition in plants, determining natural product yield, surveying the developing of organic products, Bruise identification in foods grown from the ground.
Automotive safety: Detection and tracking of pedestrians, and also other vehicles, using a small thermal camera mounted in the front of a car (or train).
Building inspection: Thermal cameras are helpful in recognizing electrical issues, moisture in buildings. Using thermal cameras it is easy to scan the complete building to detect building envelope, plumbing issues, presence of moisture in building envelopes, either from leakage or condensation and water
