Abstract

|
|
| In conventional X-ray-CT inspection of objects generated from a computer-aided design (CAD) model, a 3D CT reconstruction of the object is compared with the reference CAD model. This is a cost inefficient and tedious procedure, unsuitable for inline inspection. In this work, we propose an inspection scheme based on a limited set of radiographs, which are dynamically acquired during the scanning procedure. An efficient framework is described to determine the optimal view angle acquisition from a given CAD model and to automatically estimate the object pose in 3D with a fast, iterative algorithm that dynamically steers the acquisition geometry to acquire the optimal set of projections. We demonstrate the principle of our method on simulated data. |
