Is there a “Litchi Virtual Mission” feature for Hub 2.0? I can’t find a way to export a VLM. How can I preview a mission in Google Earth without this functionality?
Litchi Mission Hub v2 has a Google Earth view and a built-in “Simulation” function (upper right corner). These new features eliminate the need for Virtual Litchi Mission.
With the Google Earth view, one can interactively view around the mission area just as you can in Google Earth.
With the new Simulation mode, one can fly the mission while watching the camera view.
Is there a Virtual Litchi Mission function that is not addressed by these two new features?
Ah… I see it now. In my defense, it’s not intuitive.
There is one VLM feature I need though-- custom camera FOV. I use Litchi mission utilities to convert the mission to a DJI mission, which I then upload to the controller for my Air 3S . I need to be able to visualize the wide AND tele camera view in Google Earth.
The mini 3 pro camera has very nearly the same FOV as the Air 3S main camera. So I can choose that drone for the Air 3S main camera.
Is there a drone choice in the menu that has a 35 degree camera FOV?
Currently the new Litchi Hub does not take into account the selected camera’s FOV in the google earth simulation.
It may be possible to support it by resizing the google earth view, and we will consider making that work in future updates.
Is there a way to change the simulation camera FOV in Hub 2.0? Currently the simulator appears to have inherited the 83 degree FOV specified in my VLM extension. How can I simulate the 35 degree FOV of my Air 3S tele lense?
as I tried to explain in my previous post, the simulation simply fills your browser window and is not trying to replicate a given FOV. Google Earth for web apps does not currently have native support for changing the FOV, unlike the desktop version.
If I can’t select the FOV of the simulation camera, how can I properly preview a mission? I won’t know what imagery my drone camera will capture. I use the VLM preview to properly frame my videos. VLM allows me to select the FOV and is reasonably accurate. Please understand I am not complaining, but for me not being able to select the FOV is a loss of functionality.
If you export the flight to KML in the new Litchi Hub, then open the KML in google earth, you should get the results you are looking for.
However please keep in mind that we don’t list the Air 3S in the Hub for now as it is not supported with our apps. Could you let us know how you’re using the Hub with your drone model? This will help us better understand your goals.
I export a litchi mission as a csv file, then I use Litchi Mission Utilities to convert it to a DJI mission. Then I copy the kmz file to the waypoint folder on my controller (I overwrite a kmz file for a mission that was created on the controller). The mission is then available for me to fly on my Air 3S. I’ve done this several times successfully.
The KML file exported from hub 2.0 does open in Google Earth, but always has a FOV of 69.72645906888526! So unfortunately, your suggestion won’t work.
My work around for this is to edit the KML file with a text editor. I do a global find and replace of:
gx:horizFov69.72645906888526</gx:horizFov>
with:
gx:horizFov35</gx:horizFov>, where “35” is the FOV of my Air 3S tele lense.
This edited file will then open in Google Earth with the desired FOV!
The original hub VLM extension with its selectable FOV made editing the file un-necessary, so the process was smoother.
It has the horizontal FOV of the drone and camera you select in your flight settings.
If you select for example Mavic 2 Zoom with 48mm lens, then it will have a narrower fov etc
Yes! The DJI Phantom 4 Pro in your drop down list has the same FOV as the Air 3S, so that eliminates the need to edit the downloaded KML.
Thank you!
