Abstract

The Department of Civil Engineering (DCE), seat of Topography and Photogrammetry – Pisa University, is cooperating with the Excellence Centre for Telegeomatics Research of Trieste University, is developing several methods in order to evaluate road cross slope. This measurement is performed by means of instrumentation integrated on the MMS vehicle GIGI One. In particular, two different approaches are followed. The first one involves the use of a low cost monoaxial laser scanner IBEO Automotive LD GmbH, synchronized with an Applanix POS LV system. With the second one, the cross slope is computed only from inertial system data, with a simplified algorithm that describes vehicle dynamics. This paper will present an accuracy assessment of both methods. This test is carried out on two different datasets, referring to the s.s. 58 Strada Nuova per Opicina, joining Trieste to Opicina and the s.s.1 Aurelia between Rosignano and Campolecciano, near Livorno. The control compares systematically the results from the two methods and involves several single point checks by tests carried out with conventional topographic instrumentation.
