PARALLAX CORRECTION IN THERMAL IMAGING CAMERAS

摘要

A method and apparatus for reducing parallax offset in a combination infrared and visible light camera. A thermal imaging camera comprises at least two modes of operation for correcting parallax offset, and is designed to shift at least one of the visible light and infrared images by a predetermined amount. The amount of the shift is dependent at least on the mode of operation. The mode of operation may be manually selected by the user via a user interface on the camera.

主权项

1. A portable, hand-held thermal imaging camera comprising:
an infrared (IR) lens assembly having an associated IR sensor for detecting thermal images of a target scene; a visible light (VL) lens assembly having an associated VL sensor for detecting VL images of the target scene; a display adapted to display at least a portion of the VL image or at least a portion of the IR image; a processor; and a user interface; wherein the camera comprises at least two modes of operation, selectable via the user interface, and wherein, when switched from one mode of operation to the other, the processor shifts at least one of the VL and IR images by a predetermined amount.
