Determination of the Road Surface Microtexture. Chapter 12
This thesis deals with a noncontact measurement technique involving active vision, called triangulation under laser plane lighting. This optomechatronic method consists in projecting a laser sheet on an object or a surface under test, and analyzing the intersecting curve on an image taken by a camera. It allows making a wide variety of dimensional, noncontact and nondestructive, measurements (length, area, volume, diameter, curvature, reverse engineering. The original approach of the work is that the focus is brought on the determination of specific, restricted dimensional information on objects of diverse, but a priori known, shapes with the objective of achieving metrological performances in agreement with the industrial requirements. Furthermore, ambulatory instruments-i.e. devices that are at least portable or even handheld-are exclusively selected, using low-cost components. Another objective is to obtain systems for which an industrial transposition to innovative instrumental products is eventually feasible. The text is divided in two distinct parts, both strongly correlated. The first one deals with all the theoretical aspects of the method. The second part describes four innovative applications [among which] the determination of the road surface microtexture.
