  • Thermal imaging camera and method for the determination of the lens parameters of an IR interchangeable lens of a thermal imaging camera
    Patent number: 8247770
    Abstract: In a thermal imaging camera (1) with an IR sensor arrangement (2) and an interchangeable IR lens (5), an image processing unit (12) and a data processing unit (13) are provided with which at least one feature (8, 9) can be extracted from a recorded IR image (6) and a numerical value (14) can be derived from this feature, wherein the numerical value (14) is determined by the distortion of the interchangeable IR lens (5), and a mapping (16) of lens characteristics (17, 18, 19) with the determinable numerical values (14) is stored.

  • METHOD FOR THE EXTRACTION OF AN IR-IMAGE AND THERMAL IMAGING CAMERA
    Publication number: 20110199489
    Abstract: A thermal imaging camera (1) which, in order to extract IR-images (2) from a stream of crude data (12) of crude IR-images (3), performs a compensation (21) of pixel measurements (6) of the crude IR-images (3) with pixel-background values (8) pixel by pixel, with a new calculation (19) of the pixel-background value (8) being performed when the variation of the pixel measurements (6) in the measurement sequence of the crude data stream (12) for the pixels exceeds a lower limit for variations.
