double pointCost(int x, int y)
Checks the cost of a point in the costmap.
double lineCost(int x0, int x1, int y0, int y1)
Rasterizes a line in the costmap grid and checks for collisions.
double scorePose(const geometry_msgs::msg::Pose2D &pose) override
Return the obstacle score for a particular pose.
double getResolution() const
Accessor for the resolution of the costmap.
