All the research described in the previous sections is devoted to perform a step forward the state-of-the-art of surveying methods and procedures.


Indoor mapping

The research carried out at our group aims to be a step forward in improving methods and procedures for indoor navigation and mapping. Currently, the generation of this information is a technological trending topic.  We have low quality solutions at very reasonable cost (few hundred euros), but good performance positioning and mapping in interiors is still expensive (tens of thousands of euros) and requires very long acquisition campaigns.

We are working in a new low-cost modular, multi-sensor acquisition and processing platform. The platform uses the newest Commercial-of-the-Shelf sensors and process data under geodetic criteria (redundancy, heterogeneity and rigour).

Road inspection

Road traffic safety is one of the key issue for policy makers and authorities, which is required to be addressed for enabling safe and comfortable movement of goods, people and services. The safety of road users may be affected by the existence and condition of road geometry and physical factors present along the route corridor. These factors are required to be located, measured, classified and recorded in a timely, cost effective manner in order to schedule their maintenance and proper management of the road networks. The use of Mobile Laser Scanning (MLS) system overcomes the limitations existing in current road safety inspection methods by enabling rapid and cost effective acquisition of accurate information about road and its infrastructure. The acquired 3D information facilitates the comprehensive monitoring and evaluation of road infrastructure elements to identify any risk elements along the route corridor.

The main objective of the research carried out in CTTC regarding this topic aims to develop a set of methodologies and algorithms to locate, classify and measure the road infrastructure elements and any deformation existing in them, based on 3D data acquired using MLS system.

One of the most recent application of our work is related to the application of remote sensing techniques to aquiculture. In join collaboration with UPC and IRTA we studied the potential of clorophyll-a estimation from Sentinel 2 imagery to monitor the distribution and amount of phytoplankton in Ebro Delta’s bay.
