Unit and Coordinate system of SDK about windows-sdk HOT 5 CLOSED

it will be unreasonable if we apply this unit

it is float, which means the value you can set 0.0000001, 0.0000002, etc

I also want to know the start point of the coordinate system. Is it a ego-centric coordinates system or it starts from where the drone taking off? Thanks!

not quite understand what you mean, if you're asking about the GPS coordinate, it should be the same as the regular definition.

Hi, there are two options for you to ask for help:

1. Post your issues on StackOverflow: https://stackoverflow.com/questions/tagged/dji-sdk, the community can help you.

2. Report your issues to [email protected], as it's our official channel for developers to request DJI Developer Support now.

For DJI Developer Support, we have the following three tiers:

• Standard

This free support is available to anyone reaching out to [email protected]. There is no guarantee for response time.

• Preferred

  This support comes with Pro membership for 99 USD per year. You can purchase it on DJI Developer Website. These requests have priority over Standard ones. Starting today, Preferred questions will be replied to within 2 to 5 business days (Monday – Friday).

• Premium

  This one-time ticket is considered high-priority and costs 499 USD per issue. You can purchase it on DJI Developer Website after you become the Pro membership developer. Starting today, Premium questions will be replied to within 1 business day (Monday – Friday). This may include communication with DJI SDK engineers, but will not involve face-to-face interaction. Time limitations apply, and please keep in mind that one question is permitted per ticket. We will do our best to resolve your issue, but there some situations demand deeper engineering efforts.

Thanks Lanyusea. I got it, the LocationCoordinate2D is in geographical unit. So the issue I met is I want to control the drone to fly around in a in-door space, so I assume I need to do some low level control. Can you tell me what should I do? How can I build the coordinate system for my experimental playground? For instance:

Waypoint waypoint = new Waypoint()
{
location = new LocationCoordinate2D() { latitude = latitude, longitude = longitude },
altitude = 20,
gimbalPitch = -30,
turnMode = WaypointTurnMode.CLOCKWISE,
heading = 0,
actionRepeatTimes = 1,
actionTimeoutInSeconds = 60,
cornerRadiusInMeters = 0.2,
speed = 0,
shootPhotoTimeInterval = -1,
shootPhotoDistanceInterval = -1,
waypointActions = new List()
};

Replace the location's LocationCoordinate2D() by DoublePoint2D?

I assume I need to do some low level control.

yes

an you tell me what should I do?

the waypoint here is not suitable for your requirement. Waypoint is designed for long-term outdoor flight task based on GPS.

For your requirement, I suggest use DJI Onboard SDK, which is designed for lowlevel control.

If you insist using Windows SDK, the https://developer.dji.com/api-reference/windows-api/VirtualRemoteController/VirtualRemoteController.html may help

Cool, thanks. I read the document you posted here. So I assume (-1, 1) corresponds to the maximum degree that the drone can perform. And the method ‘attitudechanged’ shows the range is (-180, 180), which I assume is unavailable to perform. So I was wondering the corresponding degree to (-1, 1). Btw, my drone is Mavic Air.
