Compared with images generated based on visible light,
IR images boast the features of high background and low
contrast. In an IR image, background radiation occupies a
big part of dynamic display scope and the target object
occupies less dynamic display scope. If this object emits
weak IR ray, it will be submerged among the dark
background and difficult to be identified. To resolve the
problem, the IR image must be enhanced and
preprocessed. The thermal imaging camera allows an
image mode to be preset according to the temperature
distribution differences of a specific environment or
scenario so as to highlight the object:
