height
Description
Examples
Query Ground Surface Heights Using Surface Manager
Create a tracking scenario object.
scene = trackingScenario;
Specify the terrain as magic(4)
and define the boundary of the terrain as a square centered at the origin.
terrain = magic(4)
terrain = 4×4
16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1
boundary = [-100 100; -100 100]; groundSurface(scene,Terrain=terrain,Boundary=boundary);
Obtain the surface manager object.
manager = scene.SurfaceManager
manager = SurfaceManager with properties: UseOcclusion: 1 Surfaces: [1x1 fusion.scenario.GroundSurface]
Get the heights of the surface at the origin and its four corners.
height0 = height(manager,[0 0]')
height0 = 8.5000
height1 = height(manager,[-100 -100]')
height1 = 16
height2 = height(manager,[-100 100]')
height2 = 4
height3 = height(manager,[100 -100]')
height3 = 13
height4 = height(manager,[100 100]')
height4 = 1
Input Arguments
manager
— Surface manager
SurfaceManager
object
Surface manager, specified as a SurfaceManager
object.
positions
— Positions of surface to query
2-by-N matrix of real values | 3-by-N matrix of real values
Positions of the surface to query, specified as a 2-by-N matrix of real values or a 3-by-N matrix of real values, where N is the number of positions.
If the IsEarthCentered
property of the tracking scenario is
specified as:
false
— Each column of a 2-by-N matrix represents the x- and y-coordinates of a position in meters. Each column of a 3-by-N matrix represents the x-, y-, and z-coordinates of a position in meters. Note that the z-coordinate is irrelevant for surface height querying.true
— Each column of the 2-by-N matrix represents the latitude and longitude of a position in degrees, in the geodetic frame. Each column of the 3-by-N matrix represents the latitude in degrees, longitude in degrees, and altitude in degrees of a position, in the geodetic frame. Note that the altitude is irrelevant for surface height querying.
Output Arguments
h
— Heights of queried positions
N-element vector of real values
Heights of queried positions, returned as an N-element vector of real values in meters, where N is the number of queried positions.
