importOccupancyMap3D

Import an octree file as 3D occupancy map

Syntax

map3D = importOccupancyMap3D(mapPath)

Description

map3D = importOccupancyMap3D(mapPath) imports the octree file (.ot/bt) specified at the relative or absolute file path, mapPath

Examples

Check Occupancy Status and Get Occupancy Values in 3-D Occupancy Map

Import a 3-D occupancy map.

map3D = importOccupancyMap3D("citymap.ot")

map3D = 
  occupancyMap3D with properties:

    ProbabilitySaturation: [1.0000e-03 0.9990]
               Resolution: 1
        OccupiedThreshold: 0.6500
            FreeThreshold: 0.2000

Display the map.

show(map3D)

Check the occupancy statuses of different locations and get their occupancy values.

iOccVal1 = checkOccupancy(map3D,[50 15 0])

iOccVal1 = 0

OccVal1 = getOccupancy(map3D,[50 15 0])

OccVal1 = 0.0019

iOccVal2 = checkOccupancy(map3D,[50 15 15])

iOccVal2 = 1

OccVal2 = getOccupancy(map3D,[50 15 15])

OccVal2 = 0.6500

iOccVal3 = checkOccupancy(map3D,[50 15 45])

iOccVal3 = -1

OccVal3 = getOccupancy(map3D,[50 15 45])

OccVal3 = 0.5000
