occupancyMatrix

Convert occupancy grid to double matrix

Description

mat = occupancyMatrix(map) returns probability values stored in the occupancy grid object as a matrix.

mat = occupancyMatrix(map,'ternary') returns the occupancy status of each grid cell as a matrix. The OccupiedThreshold and FreeThreshold properties on the occupancy grid determine the obstacle free cells (0) and occupied cells (1). Unknown values are returned as –1.

Input Arguments

collapse all

Map representation, specified as a occupancyMap object. This object represents the environment of the vehicle. The object contains a matrix grid with values representing the probability of the occupancy of that cell. Values close to 1 represent a high probability that the cell contains an obstacle. Values close to 0 represent a high probability that the cell is not occupied and obstacle free.

Output Arguments

collapse all

Occupancy grid values, returned as an h-by-w matrix, where h and w are defined by the two elements of the GridSize property of the occupancy grid object.
