Nizkocenovni računalniški sistem za slikovno podvodno opazovanje

Diplomska naloga rešuje problem spremljanja sidra plovila in zagotavljanja, da je plovilo varno zasidrano. Vse trenutne rešitve ta problem rešujejo s spremljanjem lokacije samega plovila, kar v veliko primerih ni dovolj zanesljivo. Vizualno spremljanje sidra pa je brez potapljanja trenutno nemogoče. Naš sistem ta problem rešuje z bojo, ki je z jeklenico pripeta na sidro. V boji je GPS modul, ki spremlja lokacijo boje v realnem času. Ta modul je priključen na računalnik Raspberry Pi, na katerem teče spletni strežnik, preko katerega lahko z mobilno napravo dostopamo do teh podatkov. Na strežnik se povežemo preko mobilne dostopne točke. Preko UTP kabla je na Raspberry Pi povezana še IP kamera, ki je pod vodo nekaj metrov nad sidrom, obrnjena proti sidru. Preko razvite spletne aplikacije se lahko povežemo na strežnik, kjer lahko spremljamo lokacijo sidra v realnem času, dobimo opozorilo če se sidro preveč premakne, in pa spremljamo sidro preko videa iz kamere.

Abstract

This thesis is solving the problem of monitoring our vessels anchor and ensuring that our vessel is safely anchored. All current solution solve this problem by monitoring the position of the vessel itself, which is in many cases not reliable enough. Visual monitoring of the anchor, however, is impossible without diving. Our system solves this problem with a buoy attached to the anchor with a cable. Inside is a GPS module that tracks its position in real time. This module is connected to a Raspberry Pi computer running a web server through which we can access this data with a mobile device. We connect to the server through a mobile access point. An IP camera is also connected to the Raspberry Pi via an UTP cable, which is under water a few meters above the anchor, facing the anchor. We can connect to the server through our developed web application, where we can monitor the location of the anchor in real time, get a warning if the anchor moves too much, and monitor the anchor visualy via video from the camera.
