Advanced remote nondestructive inspection system and process

摘要

A system for inspecting a test article incorporates a diagnostic imaging system for a test article. A command controller receives two dimensional (2D) images from the diagnostic imaging system. A three dimensional (3D) computer aided design (CAD) model visualization system and an alignment system for determining local 3D coordinates are connected to the command controller. Computer software modules incorporated in the command controller are employed, in aligning, the 2D images and 3D CAD model responsive to the local 3D coordinates. The 2D images and 3D CAD model are displayed with reciprocal registration. The alignment system is then directed to selected coordinates in the 2D images or 3D CAD model.

1. A system for inspecting a test article comprising:
a 3D measurement and alignment system for determining local 3D coordinates; a plurality of markers positioned on a test article responsive to position designation by the 3D measurement and alignment system; a diagnostic imaging system for a test article, said diagnostic imaging system positioned on the test article responsive to position designation by the 3D measurement and alignment system; a command controller connected to the 3D measurement and alignment system and receiving two dimensional (2D) images from the diagnostic imaging system, said 2D images including the markers; a three dimensional (3D) computer aided design (CAD) model visualization system connected to the command controller; and, computer software modules incorporated in the command controller for positioning of the 3D measurement and alignment system, designating the plurality of selected alignment points with said markers positioned responsive to the alignment points designated, aligning the 2D images and 3D CAD model responsive to the local 3D coordinates, and displaying the 2D images and 3D CAD model with reciprocal registration incorporating the markers, said alignment points thereby concurrently identified in the 2D images and local 3D coordinates, said software module for aligning incorporating a scan registration matrix derived from a calibration matrix for the 3D measurement and alignment system based on the selected alignment points on the test article.
