Hi All, we have been working on automating our BlueROV2 using a visual navigation system. Our prototype system has been tested in a pool and we are working toward some field tests soon. The hardware and software components are diagrammed below, and some videos demonstrating early trials are availab…

Well done! Do you think it is possible to fuse in a USBL position while navigating to increase the accuracy of the mower track and starting point? Fantastic work!

Looks good. I am aiming to do the same thing. [image] Proposed Advanced Sub-Surface ROV Control Platform DIY ROVs Ok so things have moved on… The Nvidia Jetson Nano was released early 2019, making the Raspberry PI look a bit sad…I am currently porting all my python code…

Fantastic :+1:. I definitely want one when testing is completed please Rgs Grant Oz

Great work A few questions for either / both @brianh and @deepsouth to get their options for my own (all be it poor coding knowledge) benefit How well do you think this style system would work as a monocular system (with the camera down facing and assuming it is getting fed reasonable bottom image…

Hi Scott, Most SLAM systems will work with monocular systems (ORBSLAM does and I’ve tested it with some underwater video sequences and it performed reasonably). Using only a monocular camera the path/map will lack an absolute scale, but depending on your needs that may not be a major issue. The IM…

From the mapping side of things with a camera looking straight down, not sure if you have seen this? Its very cool… [image] Photogrammetry testing in Santorini with BR2 Dive Log One of our first attempts on using BR2 for photogrammetry. Here we are in Santorini trying to…

Thanks Brian and Andrew for the replies Thanks for the link Andrew I have been playing around with underwater photogrammetry for 5 year (see below) and is the main driver for the BlueROV2 so as not to be as limited as a diver with depth and duration Scott

Very impressive Scott! What did you use for the image above? How far have you got augmenting the technical capabilities of the BlueRov2?

Hi Andrew That image was done with a standard GoPro but not from a ROV (just me as a free swimming diver) I have done some photogrammetry from the ROV and good coverage is the hardest thing to get it working (hence the intrest in visual navigation ) I have a couple of projects in deeper water co…

Thanks Scott The camera looks good. Just checking you have seen this produce. Gigabit Ethernet switch powered by USB…not sure if its what you are looking for… Switch - (4) 10/100/1000Mbps RJ45 | Black Box
