Abstract
Thermal imaging cameras for use in retaking images and methods of retaking images with thermal imaging cameras that include the creation and use of a pose template that helps guide the camera back to the position where the original image was captured.
Claims23
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 memory adapted for storing a first VL image of a target scene captured concurrently with a first IR image of the target scene at a first position, the memory adapted for storing a second IR image of the target scene;
- and
- a processor programmed with instructions to capture the first VL image concurrent with the capture of the first IR image at the first position and at a first point in time,
- the processor programmed with instructions for processing the first IR image and/or the first VL image to create a pose template, the pose template including augmented features of the first image that provide indications of the first position;
- the processor programmed with instructions to combine the pose template with a live image of the scene on the display of the pose template and the live image to assist a user in repositioning the camera to the first position in order to capture a second IR image of the target scene at or near the first position.

- a visible (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 memory adapted for storing a first VL image of a target scene and a first IR image of the target scene each captured at a first position, the memory adapted for storing a second IR image of the target scene;
- and
- the processor programmed with instructions for subtracting the first IR image from a live IR image of the scene to create a difference image to assist a user in aligning the camera with the first position in order to capture a second IR image of the target scene at or near the first position.

A method of retaking an infrared (IR) image of a scene comprising:
- selecting a first image of the scene captured with a first thermal imaging camera in a first position;
- processing the first image to identify and augment features of the first image to create a pose template;
- combining the pose template with a live image of the scene on a display of the second thermal imaging camera pointed at the scene;
- repositioning the second thermal imaging camera until features of the live image align with the pose template indicating that the second thermal imaging camera is positioned at or near the first position, wherein the features of the live image align with the augmented features of the first image;
- capturing a second image of the scene when the second thermal imaging camera is at or near the first position;
- wherein the first and second thermal imaging cameras are the same camera or are different cameras.
3 more elements
A method of retaking an infrared (IR) image of a scene comprising:
- selecting a first IR image of the scene captured with a first thermal imaging camera;
- obtaining a live IR image of the scene;
- directing a second thermal imaging camera to process the first IR image and the live IR image to display a difference IR image;
- repositioning the camera until the camera is at or near the first position using the difference image;
- wherein the first and second thermal imaging camera are the same camera or are different cameras.
