Syntax

xy = grid2local(map,ij)

Description

xy = grid2local(map,ij) converts a [row col] array of grid indices, ij, to an array of local coordinates, xy.

example

Examples

This example uses:

Open Live Script

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

map = binaryOccupancyMap(10,10);

Get local coordinates from grid indices.

[i,j] = meshgrid(1:5);
xyLocal = grid2local(map,[i(:) j(:)]);

Input Arguments

collapse all

Map representation, specified as a binaryOccupancyMap object. This object represents the environment of the robot. The object contains a matrix grid with binary values indicating obstacles as true (1) and free locations as false (0).

Grid positions, specified as an n-by-2 vertical array of [i j] pairs in [rows cols] format, where n is the number of grid positions.

Output Arguments

collapse all

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