What would it do differently than the flight planning tools we have now (QGroundControl, HappyKillmore's GSC, Mike O's Planner)?

Having never seen a cropcam setup I'm not sure what the general functionality you are talking about is...

The mission planning software for aerial mapping provide more options for ensuring the area coverage by calculating flight lines and way points to map a particular area with required overlaps between the photographs.

I am in the beginning stages of planning a crop survey drone.  I feel there is a real need for them, and I have had interest from several farmers in checking large fields with a plane that could take clear pictures either on disc or live feed to a recorder.  I was amazed that auto-pilots are being built that can fly a pre programmed course. 

I am very new to all of this and trying to figure out what I will need, suggestions for flying fields that are a mile long just how many trips it could conceivably make with a battery or perhaps gas model.  Any help would be appreciated.

Thanks

I assume that you know the characteristics of the software provided by http://www.lentsika.ceped.it/

I have done a few aerial geographic surveys using an autopilot in a Telemaster airframe. I did the mission planning by hand. Your efforts would be very welcome.

If you have specific questions, I'll try to answer them based on my experience.

Thanks, yes I am planning something similar to Lentsika.

Nice post,

 

As a start:

- Focal length of camera.

- Flying height above datum or photo scale for certain elevation.

- Size of photo.

- Size ans shape of area to be photographed.

- Expected diff. from nadir photo

- Overlap.

- Sidelap.

 

=> Flight pattern generation

=> Trigger settings

 

I have excel sheet that I use for this type of calculations. If you PM an e-mail adress, I can send it

In case the excel workbook might be of interest also to others, here it is.

 

The spreadsheet is not advanced, just something I made for fast calculations when planning aerial photo missions. I start by calculating the distance between flight lines and each triggerpoint/photo. (Input; camera parameters, flight height and -speed, etc). Then the waypoints are built to correspond. 

Note; I originally developed this for the T3-4 competition for my EasyUAV, (EZStar using a flexipilot autopilot). It has the ability to loop over waypoints, so I just used 6 or 7 waypoints which was looped over a number of times. I do not know how this will relate to programming of other ap's.

 

The resulting flight-pattern can be viewed here: http://diydrones.com/profiles/blogs/t3-round-4-map-a?id=705844%3ABl...

You might find the attached excel file useful also.
