Optronics and Sensors

Development of processing algorithms for obtaining useful information from different heterogeneous sensors

Optronics and Sensor laboratory is in charge of developing methodologies and algorithms for exploiting and fusing the data coming from different sensors to obtain useful information for a particular application.

The laboratory counts with a wide variety of sensors including high definition cameras, infrared cameras (MWIR, LWIR), multispectral cameras, dual gimbals with visual and infrared cameras, 2D and 3D LIDARs with several ranges, object-detection radars including a SAR (Synthetic Aperture Radar). All these sensors can be mounted onboard different aerial platforms depending on their size and weight and the specific application. Depending on the application, it is possible to remotely control and adjust the parameters of these devices from a ground control station for an optimal data acquisition.

The laboratory members have experience in the design and development of real-time data processing systems with sensors onboard manned and unmanned vehicles. In the case of manned aircrafts, they have experience on certifying the installation of the developed equipments according to the DO-160 rule.

Regarding specific applications, the laboratory members have used cameras for the automatic detection and tracking of mobile objects, especially for traffic surveillance and wildlife monitoring in nature reserves. They have also performed automatic forest fire monitoring using infrared images taken from manned helicopter, for sending the data of interest to ground personnel. Infrared cameras have also been used in precision agriculture applications for the estimation of vegetation indices, and also for the inspection of wind turbines blades. They have also built 2D mosaics from terrain images taken from UAVs, as well as 3D digital elevation models. LIDAR-based detection systems have been developed for improving the safety in airport critical areas such as runways, and they have also been used for 3D models reconstruction. In the different applications, graphical user interfaces have been developed for data visualization and applications control.
