AUTOMATIC INFORMATION ANALYSIS OF COASTAL EMERGENCY INFORMATION BY VIDEOMETRY

2019-10-25T13:14:52+02:00Categories: Computer Vision|Tags: , , |0 Comments

The spatial scales (from meters to kilometers) and temporal (hours, days, years) that characterize the coastal dynamics, make that the classical measurement techniques are limited and very expensive, to study the behavior of coastal systems. The inclusion of measurement techniques by means of video images (commonly called coastal videometry), nowadays allows to describe physical processes on a wide range of spatial and temporal scales, something unthinkable until very recently. A coastal videometry system consists in cameras installed on the coast that allow the capture of images and their spatial referencing. The products derived from the image processing give very interesting information for the different activities that are developed in the coastal areas and that depend on the waves, currents and tide (hydrodynamic conditions) as well as the configuration of the beach, dunes, channels and bars (sedimentary elements). But trying to go a step further, based on these tools, [...]

MACHINE VISION BASED SYSTEM FOR BUBBLES DETECTION IN GLASS MANUFACTURING PROCESS

2019-10-29T15:54:37+02:00Categories: Quality Control|Tags: , , |0 Comments

VIDRALA manufactures glass bottles of different colors, shapes and diameters. In the manufacturing process, bubbles may appear due mainly to the temperature and oven parameters. If their presence increases over time, it is necessary to modify the oven parameters so that the bottles have the desired quality. The goal of the system is the automatic detection of the presence of bubbles during the production process of the bottles in order to know the trend in its appearance. The system developed is flexible, so that it can be adapted to different diameters and shapes as well as different colors, as well as to the variation of the speed of the production process, up to 250 bottles / min and with a resolution capacity up to 0.1 x 0.1 mm2. Considering that the system has to work 3 shifts in a production environment, it has been robustly designed against for example, [...]
