Patent ID: 8531562

Claim:
A method for marking a hot spot on an object, the hot spot being identified by infrared (IR) imaging, and the method comprising: viewing the hot spot on a blended image of the object being shown on a display of the camera, the blended image being an IR image of the object, captured through an IR lens, overlaid upon a visible light (VL) image of the object, captured through a VL lens of the camera, the VL lens being located on the camera with respect to the IR lens, such that an optical axis of the VL lens is offset from, and approximately parallel with, an optical axis of the IR lens to create a parallax error; registering the IR image of the object and the VL image of the object to correct the parallax error; and viewing a marking spot on the displayed blended image, the marking spot being in the visible light spectrum and projected by a pointer of the camera onto the object, the pointer being located on the camera in a fixed position to project the marking spot along a trajectory that is approximately equal to the optical axis of the VL lens; and re-positioning the pointer to project the marking spot onto the hot spot of the object by moving the camera while monitoring a movement of the marking spot on the displayed blended image until a location of the marking spot coincides with a position of the hot spot on the displayed blended image.
