Dynamic reconfiguration of a compact active stereovision system with digital electromagnetic actuators

Abstract : In active-stereovision measurement systems, there is usually only one static configuration for the measuring process. In this paper, a new miniaturized system which can switch dynamically between two active stereovision setups is presented. This system can change its internal configuration in less than 25 ms and consequently can extract 3D shape information that would not be accessible with only one static configuration. This configuration switch is realized by using two discrete positions digital electromagnetic actuators. The miniaturization is achieved by integrating flexible image guides connected to a compact optical probe. An experimental prototype has been designed, manufactured and tested. Experimental results are presented to demonstrate the feasibility of this new proposed system.
