Abstract

A method for inspecting an object includes determining guide image data of the object from a determined orientation, the guide image data including a guide image pixel array and a pixel property for at least one guide image pixel in the guide image pixel array. The method also includes receiving inspection image data indicative of an inspection image and associating the inspection image data with the guide image data with a processor of a computing device. Additionally, the method includes determining a property of the object based on the guide image data and the associated inspection image data.

First claim

We claim:

1 . A method for inspecting an object, the method comprising:
determining guide image data of the object from a determined orientation, the guide image data including a guide image pixel array and a pixel property for at least one guide image pixel in the guide image pixel array; receiving inspection image data indicative of an inspection image; associating the inspection image data with the guide image data with a processor of a computing device; and determining a property of the object based on the guide image data and the associated inspection image data.

2 . The method of claim 1 , wherein determining guide image data of the object from the determined orientation comprises determining guide image data based on a three-dimensional (3D) model of the object.

3 . The method of claim 1 , wherein determining guide image data of the object from the determined orientation comprises determining guide image data based on an image of a control object.

4 . The method of claim 1 , wherein the pixel property is an area of the guide image pixel, a distance of the guide image pixel, a color of the guide image pixel, an inclination of the guide image pixel, or a combination thereof.

5 . The method of claim 4 , wherein the guide image data includes a second pixel property for at least one guide image pixel in the guide image pixel array, wherein the second pixel property is a location of the guide image pixel.

6 . The method of claim 1 , wherein the pixel property is a set of distances of the guide image pixel.

7 . The method of claim 1 , wherein the inspection image data comprises an inspection image pixel array, and wherein associating the inspection image data with the guide image data comprises associating the pixel property of at least one guide image pixel with a corresponding inspection image pixel in the inspection image pixel array.

8 . The method of claim 7 , wherein determining the property of the object based on the guide image data and the associated inspection image data comprises:
designating a portion of the inspection image pixels through a user input; and determining the property of the designated portion of the inspection image pixels based on the pixel properties corresponding to the inspection image pixels.

9 . The method of claim 1 , wherein associating the inspection image data with the guide image data comprises:
determining transform data indicative of an inspection image orientation relative to the determined orientation associated with the guide image data of the object; and adjusting the inspection image data or guide image data in response to the determined transform data.

10 . The method of claim 1 , comprising initiating a maintenance action of the object in response to determining the property of the object.

11 . The method of claim 1 , wherein the object is a gas turbine engine rotor blade.

12 . The method of claim 11 , wherein the inspection image is generated with a borescope camera or an endoscope camera.

13 . An inspection system, comprising:
a visual image recording device configured to generate an inspection image of an object; and a computing system comprising a processor, the computing system configured to:
receive inspection image data indicative of the inspection image;
determine guide image data of the object from a determined orientation, the guide image data including a guide image pixel array and a pixel property for at least one guide image pixel in the guide image pixel array;
associate the inspection image data with the guide image data with the processor; and
determine a property of the object based on the guide image data and the associated inspection image data.

14 . The inspection system of claim 13 , wherein the computing system is configured to determine guide image data based on a three-dimensional (3D) model of the object.

15 . The inspection system of claim 13 , wherein the computing system is configured to determine guide image data based on a 3D scan of a control object.

16 . The inspection system of claim 13 , wherein the pixel property is an area of the guide image pixel, a distance measurement of the guide image pixel, a color of the guide image pixel, an inclination of the guide image pixel, or a combination thereof.

17 . The inspection system of claim 13 , wherein the pixel property is a set of distance measurements of the guide image pixel.

18 . The inspection system of claim 13 , wherein the pixel property is an area of the guide image pixel.

19 . The inspection system of claim 13 , wherein the computing system determines the property of the object based on the guide image data and the associated inspection image data by:
designating a portion of inspection image pixels of the inspection image through a peripheral device; and determining the property of the designated portion of the inspection image pixels based on the pixel properties corresponding to the inspection image pixels.

20 . The inspection system of claim 13 , wherein the object is a gas turbine engine rotor blade.
