Automatic Inspection of Cage Integrity with Underwater Vehicle
This thesis is a preliminary study for the initiative to develop an autonomous AUV for
use in aquaculture. A micro-ROV is used to test the concept of inspecting net integrity
in sh cages by analyzing video feed from a video camera. Software is developed, including an interactive GUI, thruster control, and the analysis algorithms. A laser
module is also developed to measure the distance between the ROV and sh cage using
two laser line generators. The conclusion is that checking for net integrity with a camera and computer vision software is a viable option in a future AUV. The laser module works well, providing reliable distance measurements for the ROV.
