- Research Areas
The application of inspection systems and 3D reconstruction inside of cavities and pipes is an important aspect in many practical applications. Harsh environments (fog, smog, soot) limit the application of optical systems (laser, computer vision,…). Ultrasonic measurements are less corrupted and can still be applied in such scenarios. By transmitting and receiving short ultrasonic pulse-waves, structures of varying sice are reconstructed according to the arrival time of echos. However, the structures under observation often lead to multiple echos; this and other distortions reduce the effective range resolution and introduce artifacts in the reconstruction.
Furthermore, irrelevant echo pulses shall be canceled, by considering multiple measurements. Finally the algorithm developed will be applied to various real-world-measurements to evaluate the quality of the reconstruction.
