Abstract

A system and method to inspect flaws associated with a part. The system includes a first image capturing device configured to capture a first set of images of the part and a computer operably associated with first image capturing device and configured to receive and analyze the first set of images. The method includes treating the part with a magnetic particle and fluorescent penetrant processing, capturing a first set of images of an outer surface of the part with the first image capturing device, and identifying a part defect with an algorithm associated with the computer.

First claim

What is claimed is:

1. A quality control inspection system, comprising:
a first image capturing device configured to capture a first set of images of a part;
a second image capturing device configured to capture a second set of images of the part at an angle relative to the first image capturing device;
a computer operably associated with the first image capturing device and the second image capturing device, the computer being configured to receive and analyze both the first set of images and the second set of images, and configured to identify a part flaw with an image of a part devoid of flaws stored within a database; and
a lighting system operably associated with the computer, the lighting system being configured to illuminate the part;
wherein the first set of images comprises an image having at least an edge of the part;
wherein the first set of images are corrected by an angle based upon the edge of the part;
wherein the lighting system is controlled by the computer to provide light consistency; and
wherein the part is pretreated with a magnetic particle and fluorescent penetrant.

2. The system of claim 1 , wherein the part is a helicopter metallic component.

3. The system of claim 1 , wherein the first image capturing device is a camera.

4. The system of claim 1 , further comprising:
a visual display operably associated with the computer, the visual display being configured to display the first set of images.

5. The system of claim 1 , wherein the inspection system is a mobile device.

6. The system of claim 5 , wherein the inspection system is a smartphone.

7. A method, comprising:
treating a part with a magnetic particle and fluorescent penetrant processing;
illuminating the part with a lighting system;
capturing a first set of images of an outer surface of the part with a first image capturing device;
detecting an edge of the component from the first set of images;
correcting an angle orientation of the first set of images based upon the edge of the component;
capturing a second set of images of the outer surface of the part with a second image capturing device spaced apart from and at an angle relative to the first image capturing device;
relaying the first set of images and the second set of images to a computer;
controlling a consistency of the lighting system with the computer;
identifying part flaws with an algorithm associated with the computer by comparing the first set of images and the second set of images with an image of a second part devoid of flaws; and
displaying the first set of images and the second set of images on a display operably associated with the computer.

8. The method of claim 7 , further comprising:
capturing a background image; and
suppressing the background image from the first set of images.

9. The method of claim 7 , wherein the part is a metallic helicopter component.

10. The method of claim 7 , further comprising:
storing any flaws in the part in an image archive.

11. The method of claim 7 , further comprising:
displaying the first set of images on a display operably associated with the computer.

12. The method of claim 7 , wherein the computer is portable.

13. A method, comprising:
treating a helicopter component with a magnetic particle and fluorescent penetrant;
illuminating the helicopter component with a lighting system;
capturing a first set of images of an outer surface of the helicopter component with a first image capturing device;
detecting an edge of the helicopter component from the first set of images;
correcting an angle orientation of the first set of images based upon the edge of the helicopter component;
capturing a second set of images of the outer surface of the helicopter component with a second image capturing device spaced apart from and at an angle relative to the first image capturing device;
relaying the first set of images and the second set of images to a computer;
controlling a consistency of the illumination with the computer;
identifying a type of the helicopter component;
identifying part flaws with an algorithm associated with the computer by comparing the first set of images and the second set of images with an image of a second helicopter component devoid of flaws; and
displaying the first set of images and the second set of images on a display operably associated with the computer.

14. The method of claim 13 , wherein the identifying a part defect is achieved by identifying surface and subsurface structural deficiencies on the outer surface of the helicopter component caused by the magnetic particle and fluorescent penetrant processing.

15. The method of claim 13 , wherein identifying a type of the helicopter component is achieved autonomously by the computer.

16. The method of claim 13 , wherein identifying a type of the helicopter component is achieved manually by a user.
