INTERNE SEITE - vertraulich

Area

Into the MikroKopter-OSD you will come with a "Click" on the tab "WayPoints" and on "Generator..." into the WayPoint-Generator.

https://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100814&g2_serialNumber=1

Here now you can choose the tab "Area".

With this function you can automatically generate any rectangular grid. Also, you can set any numbers of WayPoints (max. 200).
In example you could fly over an area systematically where you "lost" your Kopter before.
Or an excavation is getting mapped from the air. Also here you could fly over the area systematically and take photos.

Delete existing WPs

When creating new Waypoints the previous ones will be deleted

Create

Create Waypoints with the set values

Example 1 - Generate Waypoints + trigger camera at each Waypoint

In this example:

  • An area of approx. 120mtr x 144mtr should be overflown.
  • To fly over should be in a height of 30mtr. and with a speed of 1mtr/sec. .
  • The rows of the Waypoints flown by the Kopter should have a distance of 12mtr to each other.
  • The Kopter should stop in the rows each 10mtr. to take several pictures (for that reason that a few pictures are unclear).
  • The camera should look down.
  • The Kopter should point with the front (red outrigger) to the south.


Step 1
First at all you mark on the map the starting point. You can do that with a "left-click" on the chosen spot.
At this spot appears a marking point https://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100161&g2_serialNumber=1.

Step 2
For that reason that the Kopter should take each 10mtr a photo and the rows should have a distance of 12mtr to each other you need to set the appropriate Waypoints.
That are for the 120mtr 13 Waypoints (0mtr - 10mtr - 20mtr ... 120mtr) and for the 145mtr 13 Waypoints (0mtr - 12mtr - 24mtr ... 144mtr).
All together 169 Waypoints (of possible 200).

The settings are as follows:

  • DistanceX[m] = 10

  • #WPs in X = 13

  • DistanceY[m] = 12

  • #WPs in Y = 13

Step 3
The generated grid can be placed on the map in any orientation you like. Here you can, for example, align the orientation of the grid to a road or on the course of a field.
In this example we leave the "Rotation" on 0°.

  • "Rotation [°]" = 0°.

(!) Tipp
If you want to align the flight directions of the grid in different directions or set along a field you can change the value for the Rotation[°] as you want.
Here now some examples:

Example: 58°

Example: 90°

To enlarge click on the pictures

Step 4
Now you can set the height (30mtr) and the camrea tilt (downwards = 90°). For that reason that the Kopter need to point southwards you have to set a value of 180°.
You need to enter the values in that way:

  • Height[m] = 30

  • Cam-Nick[°] = 90

  • Direction[°] = 180

So that the Kopter can take some photos it should remain/wait 10sec. at each Waypoint:

  • Waiting Time:[s] = 10

To trigger the camera i.e. over a connected ShutterCable you need to set also a "WP event".
If the trigger should be triggered around each second you need to set here a value of 100:
(see also WP-Event)

  • WP event = 100

The remaining values are indicating:

  • Radius[m] = 10 =>

    • So that the Kopter can reach, even in windy weather, the Waypoint you shouldn't set a too small radius.
    • Once the Kopter reaches the radius of the waypoint it also begins the "waiting period" for the waypoint to expire.
  • Speed[0.1m/s] = 10

    • That is the speed the Kopter flies to the waypoints.
  • Elevation rate[0.1m/s] = 30

    • Has got no influence right now.

Step 5
Those set up Waypoints need to be generated now. It all takes is a "click" on "Create".

(!) Tipp

  • Is "Delete existing WPs" marked, with each "click" on "Create" the already existing Waypoints will be deleted on the map.
    If you take the mark out of the check-box you can place i.e. several grids one above the other or at different places on the map.


Example View:
http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100093&g2_serialNumber=7

After a "click" on the button "Create" those Waypoints will be entered automatically into the Waypoint-Editor:

http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100358&g2_serialNumber=1

After that into the map:
(On the right you can see the directions in which the Kopter flies along the Waypoints.)

http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100377&g2_serialNumber=1

Flight time

  • /!\ ATTENTION:

With so many Waypoints and a dwell time at each Waypoint the Kopter needs a long time until all Waypoints been flown.
For this example it takes whole 57 Minutes! (Exactly it's 56 Min/36 Sec.)

For that reason that the Kopter flies round about 8-20 minutes depending on the total weight with camera you should fly a Waypoint-Flight like this in more laps.
If we assume an average flight time of 12 minutes under load that would be all together a total of 5 laps.
The order would be in that way:

  • Waypoints P1 - P34 Transfered to Kopter. Lift off, after that land Kopter, change battery.
  • Waypoints P34 - P68 Transfered to Kopter. Lift off, after that land Kopter, change battery.
  • Waypoints P68 - P102 Transfered to Kopter. Lift off, after that land Kopter, change battery.
  • Waypoints P102 - P136 Transfered to Kopter. Lift off, after that land Kopter, change battery.
  • Waypoints P136 - P169 Transfered to Kopter. Lift off, after that land Kopter. DONE!

Why is the last waypoint approached again when you restart the Kopter?
This is purely a safety rule to ensure an overlap of the images.
But it shouldn't be done in this way. It can also be flown, beginning from the following waypoint.

TIPP

Who don't wants to calculate how long a flyover takes with those settings can use this Excel spreadsheet.
The flight time will be calculated automatically. Flight Time - Download

Example 2 - Generate Waypoints + Trigger camera permanently

In this example should be also a field been overflown in a range of approx. 120mtr x 144mtr and a height of 30mtr..

The Kopter should'n stop at each Waypoint and should continue flying without a stop from one Waypoint to the next instead.
Throughout the flight the camera should be triggered continuously in intervals.

The settings are almost the same as in example 1. But you need definetely less Waypoints. You just need only 2 Waypoints for each row.
That means you need 26 Waypoints for 13 rows (compared to 169 from the previous example).

Since the camera is triggered during the flight we need to choose a slower airspeed (Speed[0.1m/s]) so that the images are not getting fuzzy.
In this example we take a speed of 0.5mtr/s (~1.8km/h).

(!) Tipp:

  • For that reason that not every camera is the same the appropriate speed for clear photos should be individually identified with some test flights and at different speeds.

In addition you need to set the Waiting Time:[s] to "0". Hierbei hält der Kopter nicht mehr am Wegpunkt, sondern fliegt ohne halt direkt weiter zum Nächsten.

Since the camera is triggered during the entire flight the WP event is here not needed and you can set it to "0".

{i} (Explainations about the settings further down.)

The settings are as follows:

  • DistanceX[m] = 120

  • #WPs in X = 2

  • DistanceY[m] = 12

  • #WPs in Y = 13

  • Height[m] = 30

  • Direction[°] = 180

  • Cam-Nick[°] = 90

  • Speed[0.1m/s] = 5

  • Waiting Time:[s] = 0

  • WP event = 0

First at all you need to enter those Waypoint settings into the Waypoint-Editor:

http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100263&g2_serialNumber=1

After a "Click" on the button "Create" you need to enter those Waypoints settings into the Waypoint-Editor:

http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100364&g2_serialNumber=1

After that into the map:
(On the right you can see the directions in which the Kopter flies along the Waypoints.)

http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=100371&g2_serialNumber=1

Flight Time

With so many waypoints the Kopter needs a long time until all Waypoints are flown by.
For this example it takes only 29 Minutes! (Exactly 28 Min/24 Sec.)

Also here you should fly a Waypoint flight in several laps.

Settings Camera triggering

In Example 1 the camera was triggered at each Waypoint. Here the time was given to the WP event.

Those settings are described here: WP-Event Camera triggering

So that the camera in Example 2 is triggering during the entire flight we need to make two settings in the KopterTool and under the tab Outputs.

Those settings are described here: Permanently camera triggering

The Waypoint Flight

The settings are made and rhe Waypoints generated.

In the next step you can transfer the Waypoints to the Kopter. (Link: See Waypoint transfer)
At next you have to set the camera mount so that the camera is looking straight ahead (horizontal).

Now you can start the Kopter and you can "park" it in the air. Here you need to activate the function "Hold Height" and "PositionHold".

So that the Kopter can align itself (In this example the Kopter should point to the south) you need to activate the function "CareFree".

So that the Waypoint Flight can start up you need to set the GPS-Switch on "ComingHome".
Directly after you have switched the Kopter starts with the Waypoint Flight.

Is the Waypoint Flight done the Kopter parks at the last Waypoint. After that you can fly back and land the Kopter manually.
You also can switch the GPS to "OFF" and after that you switch back to "ComingHome". The Kopter will fly automatically back to the start point.
