Blue ROV with Stereo Video System

[HamishC]

Hi all,
I am building a Blue ROV with an attached stereo video system (similar to the image provided) to collect fish-habitat association data. The stereo cameras are powered separately to the ROV.

I am seeking the groups input into different design ideas and issues that may occur.

Please upload images if you have built or seen an ROV with alike additions!

Cheers,
Hamish

Hi @HamishC,

A few options from a search of the forum:

• This one looks to be almost identical to the system you’ve pictured
• This uses an extended T-slot rail, with some wide lighting
• This looks to be a similar-ish housing, but isn’t explicitly about stereo vision
• Internal stereo cameras could also be an option, albeit with reduced stereo depth range
• There may be some other insights by searching the forum for photogrammetry and the like

Hi @HamishC
Eliot is right. They are in fact the same system that we built up in 2018 for doing fish surveys. Happy to give you some guidance. euan.harvey@curtin.edu.au. We are using these systems routinely. Be cautious about off the shelf stereo-video systems. Many are for stereo-vision rather than stereo-measurement and the cameras are too close. Have a look at https://www.seagis.com.au/
