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? costly-mold-testing-with-ogden-utah-infrared-home- inspections
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
The Solution
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
