OpenCV with external camera – check

June 9, 2010

I’ve managed to get the external camera working with Processing and OpenCV on my mac. I thought it would be more difficult as I tried it about a month or so ago and it didn’t work. Oh well, it works now so I don’t care. I hope it just carries on working right up to the end of the show.

This image shows that the ‘index’ needs to be changed to indicate which camera input to work with when there is more than one available:

So this is one thing ticked off my To Do list.

I’ve also now been booked onto a slot for using the laser machine next week. If all goes to plan I’ll have a nice panel to use for my plinth which should then match with my sculpture as the same pattern will be cut into it. That way there is some correlation between the two and will be easier to identify that they are part of the same installation.

I’m also slightly concerned about how heavy the sculpture will be. It is meant to be wall mounted but the brackets I am thinking of using may not hold it up. Not to mention screwing the front (pattern cut) panel to the back (blank) panel.

I’ve just been reading that if drilling, a fixed or lathe drill is best for metal. For aluminium a fast speed rate but slow feed rate is best. Which means that the drill bit should be spinning really fast but should be pushing down through the material relatively slowly (I think). Handy info on drilling can be found here: http://www.diyfaq.org.uk/powertools/drillfaq.htm

Ideally it would be good to do this at the 3D resource center but then I’d have to leave the parts there through the week and won’t be able to do anything in between the Wednesdays. Not really an option.

There’s a DIY type shop at the corner of my road. I think I’ll pop in there to ask them what kind of stuff they can do. They might even be able to cut all my plinth parts for me and then I can assemble those at home and hopefully (if my car is fixed in time) drive it to uni when needed.  When it comes to this stuff I haven’t really got much experience. I’ve only ever really put some flat-packed wardrobes up. They came out well and are still standing so it’s a good sign I say. Oh and theres the random wood works I did when in school – that was fun. But back then it didn’t matter so much if things didn’t line up all that straight.

I’m also going to have a rifle through some of last year’s show plinths at uni. There might be something that can be recycled.

I think I should sleep now, I have a feeling tomorrow is going to be another looong day.
