Method for determining condensation risk at surface area of object, involves determining pixel rating characteristic from vapor pressure value, pixel saturation vapor pressure value and ambient air moisture value

摘要

The method involves receiving a composite thermal image of a scene using a thermal imaging camera (1). An ambient air moisture value or an ambient temperature value is determined for determining environment saturation vapor pressure value. A pixel saturation vapor pressure value is determined from the vapor pressure value. A pixel rating characteristic is determined from the vapor pressure value, the pixel saturation vapor pressure value and the ambient air moisture value, where the characteristic characterizes condensation risk at a pixel assigned region of the scene. An independent claim is also included for a thermal imaging camera comprising a receiving unit and a calculation unit.
