My name is 
Jan Albiez, I'm from Kraken Robotics in Germany.

2
00:00:10.520 --> 00:00:16.960
My job on this cruise is to test and evaluate the 
feasibility of the SeaVision laser scanner.

3
00:00:17.400 --> 00:00:25.000
We want to test and find out how we can use 3D laser scanning to improve the science on NOAA vessels.

4
00:00:29.880 --> 00:00:32.280
Look at that. Oh my god.

5
00:00:34.040 --> 00:00:40.920
Yeah, this is amazing. I know there are people back at that are jumping up and down at the moment as well.

6
00:00:43.040 --> 00:00:47.120
First off, SeaVision is an optically guided system. So you can only scan stuff you can see.

7
00:00:47.840 --> 00:00:55.800
You aim one of the main cameras of the scanner at your target and then you sweep one of the lasers over your object.

8
00:00:56.640 --> 00:00:59.920
And while we do this, we record every image and do triangulations.

9
00:01:06.160 --> 00:01:10.840
Normally, you can only look at camera data to give you an idea of how large and how big things are.

10
00:01:11.240 --> 00:01:19.520
Laser scanning is fully metric. That means you can measure within the point cloud and we have accuracy around plus, minus one to three millimeters.

11
00:01:20.560 --> 00:01:23.920
So it allows you to actually measure, for example, the size of a stem of a coral.

12
00:01:24.640 --> 00:01:29.400
And you can come back a couple of years later and measure again and this gives you an exact number on how much this coral grows.

13
00:01:31.680 --> 00:01:33.000
Which part do you want to know?

14
00:01:33.880 --> 00:01:35.560
That stalk there. The diameter of that.

15
00:01:36.320 --> 00:01:40.840
To there? Four centimeters, roughly.

16
00:01:41.560 --> 00:01:44.600
Wow. Scientists are gonna love that.

17
00:01:48.320 --> 00:01:52.920
On the other hand, if you go for shipwreck and you want to know how much of something is still left, for example,

18
00:01:53.880 --> 00:01:59.160
or how high above the ground something is or all the things archaeologists want to know,

19
00:02:00.000 --> 00:02:03.160
you can actually really get exact numbers. You don't have to estimate anymore.

20
00:02:05.080 --> 00:02:05.080
The video footage is combined with the scans, gives a good idea of the state of the wreck at the moment.

21
00:02:11.760 --> 00:02:16.440
Sounds like this is continuing to be a good test for the scanning system and a good survey of the wreck.

22
00:02:17.480 --> 00:02:23.440
Absolutely. For me, that's actually one of the coolest days of my professional life, to be quite honest.
