# Camera Trigger System 2.0

Stage 1. TRIGGER SYSTEM

We need a new way to trigger our cameras using arduino, raspberry PI or Beagleboard or custom PCB that simply closes a loop which will activate the triggers the cameras ([url removed, login to view] stereo cable). The loop is stereo so essentially will be in two stages, line 1 is focus line 2 is shutter. The focus loops for 1 second followed by shutter for 1 second.

Stage 1.1 Gyro function:

The trigger needs a tolerance factor so that it only is released when we are in a certain pitch and roll range, as we don't want to take photos whilst banking or climbing

Close loop if the following constraints comply (ignore my crude code)

int maxPitch = 3 // in degrees

int maxRoll = 5 // in degrees

1. Pitch =<maxPitch

2. Roll =<maxRoll

We also need a LED with red light or green light so we know if the system is level and ready to fire or in a status of pitch or roll.

Stage 1.2 GPS Trigger Function

The trigger will only fire when at a set GPS grid point, predetermined in a system. This part is hard to explain but not too difficult to apply if you you can think outside the square and know Math.

What I require is a static grid of gps points around the world that I would always refer to, evenly spaced 300m apart (if this number could be defined as an int that I could change later it would be awesome but not essential to get the ball rolling).

A generic grid means all the photos will be in the same spot to allow for me to update the database with new photos as the years go on.

If the GPS position is within say 50m of a point (also refined as an Integer) it will close the loop.

I am not a math expert, however I found a few ways of doing this by doing a google search. If the value matches one of the results of a math equation that gives us the 300m spacing then the loop closes. This also could be as a certain decimal spacing in the Lat / Lon cordinate. I.e. every .00267 degrees from 0. so S0.0 E0.0 becomes [url removed, login to view] [url removed, login to view], [url removed, login to view], E0.00534. The only problem with this is the lng will change depending where you are latitudinally (the earth is a sphere).

We also need LEDs telling us when the GPS is within a distance that it can take photos. We do all our surveys along one of these Lat or lon lines, so essentially one will be on green if we are in the area needed, whilst the other flashes green as we pass the lines.

Stage 1.3 GPS Logging

Every time a trigger is activated, a time, date, altitude, and bearing is stamped onto an SD or Flash drive.

Stage 1.4 LCD (optional)

Have an LCD display instead of the LED's, including distance from closest point and current pitch and roll. This will allow us to know if we are going off the track we need to be travelling along, and how far to run until next point.

Stage 1.5 PCB

This trigger system implemented in a custom PCB (optional), no case needed.
