I added a GPS star mission for light painting and virtual stich in my DJI iOS advanced 4.14 sample.
We can add a GPS star with an individual radius and with x edges.
If the star has 5 edges we add 10 points.
//MARK:- GPS Star Mission func star(radius: Double, points: Int, latitude: Double, longitude: Double, altitude: Double) -> [[Double]] { var grid: Array = [[Double]]() var coor: CLLocationCoordinate2D var angle: Float = 0 let R: Double = 6371000 for z in 0..<points { angle = 360 / Float(points) * Float(z) angle = yawControl(yaw: angle) // for +/- 180° if z % 2 == 0 { coor = self.newCoor(latitude: latitude, longitude: longitude, distance: radius, bearing: angle, radiusM: R) } else { coor = self.newCoor(latitude: latitude, longitude: longitude, distance: radius/2, bearing: angle, radiusM: R) } if z == 0 { grid = [[Double(coor.latitude), Double(coor.longitude), altitude]] } else { grid.append([Double(coor.latitude), Double(coor.longitude), altitude]) } } coor = self.newCoor(latitude: latitude, longitude: longitude, distance: radius, bearing: 0, radiusM: R) grid.append([Double(coor.latitude), Double(coor.longitude), altitude]) return grid }
//MARK:- GPS Lat func latm(latitude: Double, distance: Double, bearing: Float, radiusM: Double = 6371000) -> Double { let dr: Double = .pi / 180.0 let rd: Double = 180.0 / .pi return asin(sin(latitude*dr) * cos(distance/radiusM) + cos(latitude*dr) * sin(distance/radiusM) * cos(Double(bearing)*dr)) * rd } //MARK:- GPS Lon func lonm(latitude: Double, longitude: Double, latitudeM: Double, distance: Double, bearing: Float, radiusM: Double = 6371000) -> Double { let dr: Double = .pi / 180.0 let rd: Double = 180.0 / .pi return longitude + atan2(sin(Double(bearing)*dr) * sin(distance/radiusM) * cos(latitude*dr), cos(distance/radiusM) - sin(latitude*dr) * sin(latitudeM*dr)) * rd } //MARK:- GPS New Coordinate func newCoor(latitude: Double, longitude: Double, distance: Double, bearing: Float, radiusM: Double = 6371000) -> CLLocationCoordinate2D { let latitudeM: Double = self.latm(latitude: latitude, distance: distance, bearing: bearing, radiusM: radiusM) let longitudeM: Double = self.lonm(latitude: latitude, longitude: longitude, latitudeM: latitudeM, distance: distance, bearing: bearing, radiusM: radiusM) return CLLocationCoordinate2DMake(latitudeM, longitudeM) }
Use the front LED to swith on and off your additional light for the painting
//MARK:- Front LEDs On Off func frontLed(frontLEDs: Bool) { let FC = self.fetchFlightController() if FC != nil { let led: DJIMutableFlightControllerLEDsSettings = DJIMutableFlightControllerLEDsSettings.init() led.frontLEDsOn = frontLEDs FC?.setLEDsEnabledSettings(led, withCompletion: { (error: Error?) in if error != nil { NSLog("Error set front Led \(frontLEDs)") } else { NSLog("Set front Led \(frontLEDs)") } }) } }
