Method and apparatus for inspecting countersinks using composite images from different light sources

摘要

Method and apparatus for measuring dimensionality of a component are disclosed herein. At least a first image may be collected from a first camera of an aperture or a first precision countersink of the component. The first camera may be in a first position and may operate in one or more luminance environments. At least a second image may be collected from a second camera of the aperture or a second precision countersink of the component. The second camera may be in a second position and may operate in an alternative lighting environment to differentiate characteristic features including hole and countersink against their intersection with the component. Positional and process refinement parameters may be calculated for, and provided to, one or more numerically controlled mechanisms, based on the collected first and second images.

1. A method for measuring dimensionality of a component, the method comprising:
collecting at least a first plurality of images from a first camera of a first precision countersink of the component, wherein each of said first plurality of images is collected using a different light source of a plurality of light sources, and wherein a first image of said first plurality of images is captured by said first camera when a first light source of said plurality of light sources is activated and a second light source of said plurality of light sources is inactivated, and a second image of said first plurality of images is captured by said first camera when said second light source of said plurality of light sources is activated and said first light source of said plurality of light sources is inactivated, wherein said first camera comprises a first lens and is attached to and housed within a housing, and wherein said first lens is circumferentially shielded by a first end portion of a first elongate hollow tube that extends from said housing, said first elongate hollow tube further comprising a second end portion that comprises a first mirror and a first opening; generating a composite image of said first precision countersink using said first plurality of images, wherein generating said composite image of said first precision countersink comprises superimposing said first plurality of images; calculating positional and process refinement parameters for one or more numerically controlled mechanisms associated with said first precision countersink, based on dimensionality of said first precision countersink in said generated composite image; and feeding back said positional and process refinement parameters to provide adaptive control of said one or more numerically controlled mechanisms.
