In a thermal imaging camera (), an infrared image data stream () of infrared images () is captured during a random movement of the thermal imaging camera (), and the infrared images () are combined into a higher-resolution infrared image ().

Method for preparing images in non-visible spectral ranges, and corresponding camera and measuring arrangement

In the case of a measuring device for recording a sequence of individual images () in a non-visible spectral range, a method for generating an SR image () having an image resolution that is higher than an image resolution of the individual images () is provided, wherein, for the individual images (), a displacement vector field () is determined with a calculation of the optical flow and the individual images () are segmented into segments () with regard to the values of the displacement vector field (), and an optimization method is carried out for calculating the SR image () from the individual images () with variation parameters individually assigned to the segments ().

Method for generating super-resolution images having improved image resolution and measuring device

For a thermal imaging camera (), features are extracted from a series of at least two infrared images () or visible images () associated therewith by a feature analysis, and an optimal correspondence between features extracted from the images () is determined, and a translation vector () that relates the pixels of the first infrared image () to pixels of the second infrared image () is determined for the image positions () of the corresponding features.

Image processing method and thermal imaging camera

In a thermal imaging camera for acquisition of thermographic images of a measurement object, an electronic evaluation unit is integrated into the thermal imaging camera; it is designed for recognition of corresponding partial regions of the acquired thermographic images, and with it, the acquired images can be assembled into an overall image by overlapping the corresponding partial regions and displayed. The acquisition of the images preferably takes place during the swiveling of the thermal imaging camera over the solid angle region of the desired overall image.
