Photogrammetry with gluonpilot

[Tom]

Hi Alex,

Which auto mode did you use in gluonmapper? The one based on timestamps or the one based on CHDK data?

Hi Tom,

I have used the one based on timestamps ( Gluonpilot log+ any camera).

Hi Alex,

This method tries to find the first Gluonpilot trigger in the log + the first JPEG and calculates the time offset. It cannot compensate for the delay of the camera, so you have to add this delay manually. Assuming the camera delay is between 1 and 2 seconds, would that improve a lot?

After several hours of analysis/investigation I have found the issue.

Now I have a very nice excel file with the following columns name : image name (eg. : IMG_6023.jpg) , Latitude , longitude, altitude, pitch, roll, yaw.

I want to insert automatically on the picture exif the corresponding info from the excel file, but I cannot find the right program. If you have some ideas please tell me.

Thank you,
Alex

P.S. This post is a little offtopic , sorry for that.

GluonMapper does this

GluonMapper does this

Mmmm .... it will be great !! Can you give some guidelines ?

What is the format of the excel file , what column it must have ?

Thank you.

Good evening,

After couple of flights (almost no wind) I am really impressed by Z-type survey, a very nice feature!!

I want to test it also on windy days to see how well the wing is doing the turns.



What it could be nice to implement for photomapping purpose :

1. Area covered by the photomapping - value displayed while building the survey polygon;
2. to have on the *.KML file the real flight pattern and the programmed one ( imagine the 2 pictures from above overlapped).

P.S. Also very interesting features for photomapping here:

Good evening,

I had made some more flight using the Z-type survey , I can say only that is the best thing invented since the wheel .

By changing the camera parameters I have improved the picture quality :



The majority of my flights were done over a flat land but what will happen if I will decide to fly over a hill ?

The ideea is like this : I start the flight at the bottom of the hill and I want that during the photomapping flight to cover all the hill.

By having 100m altitude as relative (in the Build route section) I can assure a flight at 100m altitude all over?

In another words, I want to "copy" the profile of the hill at 100m altitude "offset", is possibe?

Thank you,
Alex

The relative altitude will refer to the home position when the module started up. So no matter what, the altitude will be constant during flight. If you want to follow the altitude of the hilll, you would need to change the altitude per waypoint manually.
Of course it will try to reach the target altitude as soon as possible... Here we don't have any high hills to practice

Good evening,

More results done using X5 wing:



Now i'm quite satisfied about the 2D stitch results (Microsoft ICE).

The thing to be improved now is regarding the flightplan route.

Due to the fact that I do not have an estimation of the length/width /area covered/total length of the flightplan sometimes I am realizing during the flight that is not enough "juice" in the battery left and I must abord the mission.

Tom, please tell me that this request is on the to do list



Thank you,
Alex
