The Problem
Current infrared camera technology makes it difficult to identify points of interest due to: Thermal and Visible Images are inconsistent
Thermal Images do not look similar to visible light images
Especially in low contrast images it can be difficult to see the “edges”

E.g. Where is this man’s chin?

This is how other people fixed this problem
Control Image A visible light (VL) image taken using a separate VL camera built into
the IR camera
E.g. FLIR ThermaCam® P65
Does not offer automatic alignment or merging of images
Laser Pointer Laser allows user to manually point laser into area of interest
E.g. FLIR ThermaCam® E65
The laser is not visible in the IR spectrum
Problematic if there is a large hot or cold spot
Hard to identify exact area of interest
Kirk R. Johnson, Thomas McManus, and John W. Pratten
Their solution Combine both solutions
The title of the patent
Visible Light and IR Combined Image Camera with a Laser Pointer
This is new! Offers automatic alignment of VL images and images corrected for
parallax error
Can blend VL and IR images
Higher contrast => Allows for cheaper, higher quality IR imaging
Uses a laser pointer to identify area of interest as well as align the images
