ABSTRACT
This chapter describes an overview of our vision-aided automated vibrometry system. It presents some background and related work. The chapter discusses the calibration issues among the multimodal sensory components. It shows the algorithms for feature matching and distance measuring using the system. The chapter describes the adaptive and collaborative sensing approach. It provides some experimental results. The chapter provides some results on distance measuring, surface selection, auto-aiming using laser–camera alignment, and surface focusing and listening using our multimodal sensory system. It presents a dual-pan–tilt–zoom (PTZ) camera–based stereo vision system for improving the automation and time efficiency of Laser Doppler vibrometers (LDV) long-range remote hearing. The LDV works according to the principle of laser interferometry. The system consists of a single-point LDV sensor system, a mirror mounted on a pan – tilt unit (PTU), and a pair of PTZ cameras, one of which is mounted on the top of the PTU.
