Photogrammetry with gluonpilot

[fba]

About the blurred image, the rotational acceleration is no good when the diaphragm camera is open, so is better put the camera in the center of gravity (very lovely point for Gluon module, batteries etc, It´s a party point, ). As general, shutter speed works fine between 1/500s and 1/1000s.

There are other good cameras you can buy from second hand like Sony NEX-5, Olympus Pen, Panasonic GF1... and aren't Cannon (so no CHDK). All have fixed shutter speed an a medium sensor size but more heavy. For any camera you choose I think is good to store picture at RAW format. You have time to lose quality later. There are shops (no publicity) who sell ready breakboard with microcontroller to read PWM (from Gluonpilot) and switch on IR LED or optocoupler (I don´t tested today). Optocoupler is a good option to handle your camera shutter board if it hasn´t IR remote controller.

I will remove publicity if it's not allowed ¿?. This is the switch for PPM or PWM.

It would be good it everyone could let the gluonpilot users know which triggering devices they have used with gluonpilot and if it functioned according to their expectations.

I have tested the CHDK method & camremote. They both worked good, but I'm thinking of switching from CHDK to IR-or another triggering method because the CHDK method is more complex and only works with older camera models.

Thanks for the info. This seems to make sense. But most people have no clue about the image sensor size. Maybe we should include some info for standard cameras such as a canon powershot.

Tom,

here is a nice tool used on Ardupilot Mission Planner :

Exactly what I was thinking! I'll see if I can put something similar into the next release!

[Tom]

Doesn't this look better?

I do feel their calculation of the overlap is incorrect... Any experts?

[Tom]

Overlap was correct, I made a mistake, it's fixed

Screenshot showing my exact data.

I use a canon ixus 120HS with a CHDK script. It shoots 1 photo per 1,7seconds meaning I get a 30% overlap.

Tom, you're moving fast , indeed it's looking nice.

More informations about the image sensor format can be found here :

Also to better understand the numbers i put on some comments on the image posted by you:

Tom, if you will have time can you do/post some flights / flightslogs , for flights done with the autopilot ? I want to see how well is following the paths,waypoints in different wind condition.

Tom , any idea when you will release this new tool?

[Tom]

Now in the new beta release
