Member Function Documentation

Fill the outline of a polygon, in this case the robot footprint, in a grid.

Parameters:
footprintThe list of cells making up the footprint in the grid, will be modified to include all cells inside the footprint

Definition at line 123 of file footprint_helper.cpp.

std::vector< base_local_planner::Position2DInt > base_local_planner::FootprintHelper::getFootprintCells ( Eigen::Vector3f  pos,
std::vector< geometry_msgs::Point footprint_spec,
const costmap_2d::Costmap2D costmap,
bool  fill 
)

Used to get the cells that make up the footprint of the robot.

Parameters:
x_iThe x position of the robot
y_iThe y position of the robot
theta_iThe orientation of the robot
fillIf true: returns all cells in the footprint of the robot. If false: returns only the cells that make up the outline of the footprint.
Returns:
The cells that make up either the outline or entire footprint of the robot depending on fill

get the cellsof a footprint at a given position

void base_local_planner::FootprintHelper::getLineCells ( int  x0,
int  x1,
int  y0,
int  y1,
std::vector< base_local_planner::Position2DInt > &  pts 
)

Use Bresenham's algorithm to trace a line between two points in a grid.

Parameters:
x0The x coordinate of the first point
x1The x coordinate of the second point
y0The y coordinate of the first point
y1The y coordinate of the second point
ptsWill be filled with the cells that lie on the line in the grid
