A method for remote non-destructive inspection, NDI, comprising: placing a NDI scanner mountable to a test article at a local site; placing a local positioning system, LPS, positioned adjacent the test article; connecting the NDI scanner, LPS and a three dimensional, 3D, computer aided design, CAD, visualization application for a CAD model of the test article to a remote command controller; designating with the LPS through the command controller a correct position for the NDI scanner on the test article; receiving scan data from the NDI scanner and creating 2D scan images; wherin the method includes calibrating the LPS for transmission of 3D coordinates of the test article to the remote command controller; calculating in the remote command controller a scan registration matrix for 2D data from the NDI scanner to 3D coordinates; calculating in the remote command controller an inverse scan registration matrix for 3D coordinates in the CAD model to display in the 2D scan images; displaying the CAD model and 2D scan images with reciprocal registration of selected points; and, re-directing the LPS responsive to a selected point in the 2D scan image or CAD model with a set of 3D coordinates from the command controller; and wherein the method includes: placing at least three 3D alignment marks (45a, 45b, 45c), defining 3D location reference calibration points, on the test article within the scan region; and computing the scan registration matrix based on at least three corresponding 2D scan image registration points (45a', 45b' and 45c') and the at least three 3D location reference calibration points (45a, 45b, 45c) to provide direct mapping between 2D pixel coordinates of the NDI scan data and the 3D coordinate system of the test article. placing a NDI scanner mountable to a test article at a local site; placing a local positioning system, LPS, positioned adjacent the test article; connecting the NDI scanner, LPS and a three dimensional, 3D, computer aided design, CAD, visualization application for a CAD model of the test article to a remote command controller; designating with the LPS through the command controller a correct position for the NDI scanner on the test article; receiving scan data from the NDI scanner and creating 2D scan images; calibrating the LPS for transmission of 3D coordinates of the test article to the remote command controller; calculating in the remote command controller a scan registration matrix for 2D data from the NDI scanner to 3D coordinates; calculating in the remote command controller an inverse scan registration matrix for 3D coordinates in the CAD model to display in the 2D scan images; displaying the CAD model and 2D scan images with reciprocal registration of selected points; and, re-directing the LPS responsive to a selected point in the 2D scan image or CAD model with a set of 3D coordinates from the command controller; and wherein the method includes: placing at least three 3D alignment marks (45a, 45b, 45c), defining 3D location reference calibration points, on the test article within the scan region; and computing the scan registration matrix based on at least three corresponding 2D scan image registration points (45a', 45b' and 45c') and the at least three 3D location reference calibration points (45a, 45b, 45c) to provide direct mapping between 2D pixel coordinates of the NDI scan data and the 3D coordinate system of the test article. placing at least three 3D alignment marks (45a, 45b, 45c), defining 3D location reference calibration points, on the test article within the scan region; and computing the scan registration matrix based on at least three corresponding 2D scan image registration points (45a', 45b' and 45c') and the at least three 3D location reference calibration points (45a, 45b, 45c) to provide direct mapping between 2D pixel coordinates of the NDI scan data and the 3D coordinate system of the test article.
