world2local

Convert world coordinates to local coordinates

Since R2019b

Syntax

xyLocal = world2local(map,xy)

Description

xyLocal = world2local(map,xy) converts an array of world coordinates to local coordinates.

Examples

Convert World Coordinates in Occupancy Map to Local Coordinates

Create an empty occupancy map with a width and height of 10 meters.

map = occupancyMap(10,10);

Get local coordinates from world coordinates.

[xWorld,yWorld] = meshgrid(0:0.5:2);
xyLocal = world2local(map,[xWorld(:) yWorld(:)]);

Input Arguments

map — Map representation

occupancyMap object | mapLayer object | multiLayerMap object | signedDistanceMap object

Map representation, specified as a occupancyMap, mapLayer, multiLayerMap, or signedDistanceMap object.

xy — World coordinates

n-by-2 vertical array

World coordinates, specified as an n-by-2 vertical array of [x y] pairs, where n is the number of world coordinates.

Output Arguments

xyLocal — Local coordinates

n-by-2 vertical array

Local coordinates, specified as an n-by-2 vertical array of [x y] pairs, where n is the number of local coordinates.

Introduced in R2019b

R2023a: Signed Distance Map Support

The world2local function now supports the signedDistanceMap object as a new map representation for the map argument.
