6 . The method of claim 1 , further comprising determining one or more properties of the object based on the pixel property of each pixel in the one or more pixel arrays comprises:

designating a portion of the inspection image through a user input; and

determining the property of the designated portion of the inspection image based on the pixel properties corresponding to the one or more pixel arrays designated in the inspection image.

7 . The method of claim 6 , comprising initiating a maintenance action of the object in response to determining the one or more properties of the object.

8 . The method of claim 1 , wherein the inspection image is generated with a borescope camera or an endoscope camera.

9 . An inspection system, comprising:

a visual image recording device configured to be inserted through a borescope opening of a gas turbine engine and generate an inspection image of a three-dimensional (3D) object; and

a computing system comprising a processor, the computing system configured to: receive the inspection image of the 3D object, the inspection image comprising a plurality of inspection image pixels and a corresponding location of each of the plurality of inspection image pixels;

determine an orientation of the object in the inspection image relative to the visual image recording device via a 3D pose recovery regression;

create a simplified two-dimensional (2D) image of the object in the determined orientation; and

project properties of a three-dimensional model in the determined orientation onto one or more pixel arrays that collectively form a property map, wherein the corresponding location of each of the plurality of inspection image pixels and the determined orientation are used from the inspection image to form the property map and align the property map with the inspection image, wherein the corresponding location of each of the plurality of inspection image pixels is associated with the simplified 2D image to aid in aligning the property map with the inspection image, wherein each pixel in the one or more pixel arrays include a pixel property representing a physical characteristic of the object, and wherein each pixel in the one or more pixel arrays is aligned with the corresponding location of each pixel in the one or more pixel arrays.
