Patent number: 10931901Abstract: A method and a thermal imaging device for correcting fixed pattern noise of in a video sequence of thermal images captured using a thermal imaging system are provided. The method includes receiving a sequence of thermal images captured using a thermal imaging system. The method also includes calculating a thermal image average of a plurality of the received thermal images and calculating pixel difference values between a received thermal image and the thermal image average. The method evaluates the pixel difference values in relation to an updating condition and calculates fixed pattern noise correction terms for the pixel difference values for which the updating condition is fulfilled. The method also includes correcting pixel values of a subsequently received thermal image with the fixed pattern noise correction terms to generate a sequence of thermal images having corrected fixed pattern noise.Type: GrantFiled: August 30, 2017Date of Patent: February 23, 2021Assignee: FLIR SYSTEMS ABInventor: Stefan Olsson

Patent number: 9979903Abstract: Various techniques are provided for a stray light compensation method for an infrared (IR) camera. For example, a stray light compensation method includes: capturing an IR image of a scene by an IR camera, generating a fixed pattern noise estimate FPNestt0 for time t0 using the captured IR image and a stray light model associated with the IR camera, and performing a fixed pattern noise (FPN) compensation of the captured IR image based on said FPNestt0 to obtain a stray light compensated IR image. The fixed pattern noise estimate may be generated through operations in a frequency domain representation of the captured IR image and the stray light model according to one or more embodiments.Type: GrantFiled: February 6, 2017Date of Patent: May 22, 2018Assignee: FLIR Systems ABInventors: Emanuel Johansson, Odd Larson, Stefan Olsson
