Thermal imaging camera and method for constructing a thermographic image

In a thermal imaging camera (30) for acquisition of thermographic images (32, 32a, 32b, 32c, 32d, 32e) of a measurement object (49), an electronic evaluation unit (80) is integrated into the thermal imaging camera (30); it is designed for recognition of corresponding partial regions of the acquired thermographic images (32, 32a, 32b, 32c, 32d, 32e), and with it, the acquired images (32, 32a, 32b, 32c, 32d, 32e) can be assembled into an overall image (50) by overlapping and stitching together the corresponding partial regions and displayed. The acquisition of the images (32, 32a, 32b, 32c, 32d, 32e) preferably takes place during the swiveling of the thermal imaging camera (30) over the solid angle region of the desired overall image (50).
