  • 摘要:In recent years, laser scanning measurements have been widely used to detect topographic and urban features. In this article, we present a method to integrate mobile laser scanning (MLS) data and panoramic images for producing a textured surface model within a fluvial environment. We also describe the use of the textured surface model to characterize and interpret changes caused by high discharges. The accuracy of MLS-based digital terrain models (DTM) and change detection is evaluated by using static terrestrial laser scanning (TLS) measurements as a reference. The laser scanning data was measured with the mobile mapping system developed in co-operation with the Finnish Geodetic Institute and Aalto University. The boat-based system (BoMMS) has been specially developed for fluvial geomorphology and river mapping. We created panoramic image mosaics by combining sequences of digital images. These methods are suitable for collecting detailed data when traditional methods are unable to gather the data needed for fluvial modelling. The paper also presents a process chain for combining these data sources.
