Resource: Wildlife Speed Cameras: Measuring animal travel speed and day range using camera traps

Travel speed and day range are metrics usually derived from telemetry or direct observations. A new (open access) paper in Remote Sensing in Ecology and Conservation,...

Here's a set of tools that could be applicable to this idea

 https://github.com/pfr/VideoSpeedTracker

Hi Steph - just to follow up on your post: @MarcusRowcliffe , James Durrant and I have been working on a bit of software to implement the "computer vision" techniques that are mentioned in that paragraph. You can see a demonstration of it in action here. It requires camera-trappers to "calibrate" their camera traps during setup (or take-down), by taking pictures of a standard object (for example, we use a 1m pole held vertically) at different distances. The calibration takes ~10 mins per location. From this, you can reconstruct the paths that animals take infront of cameras, the total distance they travelled, and therefore their speed.

Hi Steph,

Only just discovered this site, so I'm a bit late to the game.

I'd love to hear what your main take-aways were from this meeting!

Best,

Louise

Hi Louise, 

Welcome! Unfortunately, an uncomfortably busy calendar meant I ended up missing this gathering. However, I'm sure that @SteffenOppel @Tomswinfield  or @ali+johnston (I think you were all involved?) might be kind enough to jump in here and share some of their key take aways from this discussion?   

Steph

Camera traps reveal mysteries of nature

Roland Kays
Sharing personal 'best of' animal pictures is a favorite pastime of many camera trappers. A prolific camera trapper himself, Roland Kays has pulled together more than 600 images collected by 152 researchers from 54...

Discussion: Self-powered camera trap

Back in April I read about this project out of Columbia University for a self-powered camera that uses the light hitting the sensor to power the camera. It's a cool idea, and...

I was initially thinking of dozens or maybe even hundreds of nodes coming back to a central wired connection point. I wonder if something like Google's project Loon could work in place of an on-the-ground network.

But stepping back from the tech for a moment, really the problem we're trying to solve here is being able to have remote monitoring cameras that don't need anyone to go out to change batteries or memory cards. After salaries, vehicles/transportation is the top expense at pretty much all of the conservation partners we have. Anything we can do to reduce the travel (and the time of the people as well) is huge.

So, in terms of power, does the "classic" solution with a set of solar panel cells on top of the box have some major flaws? I'm pretty sure I've seen self-powered meteo stations looking like this positioned along motorways/higways (don't remember what country or even a continent was it :-) Not being an expert in photo-voltaics, I would risk saying that a purposely-designed cell pointing up, directly at the sun, will have better efficiency than a re-purposed CMOS censor :-)

And indeed, talking to something overhead (either the baloons or Facebook's drones - forgot the name - or maybe even satellites?) would be probably much simpler than ground-based communication. If we had big enough energy budget, the communication channel would be "relatively easy" to implement...

Some camera trap manufacturers offer solar power as an add-on or option off the shelf. I agree that using the image seems like a solution looking for a problem.

thanks for this very interesting post! i was also trying to develop an inexpensive camera trap but with not good results. i think the use of a PIR sensor can give more battery life than motion detection via software. Can you give more details about the components you used please?

Thanks
Paolo

Hi Sorry been away, I'll list more about parts etc.. In the mean time the Pi Zero has just had an upgrade..
