Constructor & Destructor Documentation

DrawRectangleAlgNode::DrawRectangleAlgNode ( void )

Constructor.

This constructor initializes specific class attributes and all ROS communications variables to enable message exchange.

Definition at line 4 of file draw_rectangle_alg_node.cpp.

DrawRectangleAlgNode::~DrawRectangleAlgNode ( void )

Destructor.

This destructor frees all necessary dynamic memory allocated within this this class.

Definition at line 26 of file draw_rectangle_alg_node.cpp.

Member Function Documentation

void DrawRectangleAlgNode::addNodeDiagnostics ( void ) [protected, virtual]

node add diagnostics

In this abstract function additional ROS diagnostics applied to the specific algorithms may be added.

Implements algorithm_base::IriBaseAlgorithm< DrawRectangleAlgorithm >.

Definition at line 109 of file draw_rectangle_alg_node.cpp.

void DrawRectangleAlgNode::image_in_callback ( const sensor_msgs::Image::ConstPtr & msg ) [private]

Definition at line 45 of file draw_rectangle_alg_node.cpp.

void DrawRectangleAlgNode::mainNodeThread ( void ) [protected, virtual]

main node thread

This is the main thread node function. Code written here will be executed in every node loop while the algorithm is on running state. Loop frequency can be tuned by modifying loop_rate attribute.

Here data related to the process loop or to ROS topics (mainly data structs related to the MSG and SRV files) must be updated. ROS publisher objects must publish their data in this process. ROS client servers may also request data to the corresponding server topics.

Implements algorithm_base::IriBaseAlgorithm< DrawRectangleAlgorithm >.

Definition at line 31 of file draw_rectangle_alg_node.cpp.

void DrawRectangleAlgNode::node_config_update	(	Config &	config,
		uint32_t	level
	)		`[protected, virtual]`

dynamic reconfigure server callback

This method is called whenever a new configuration is received through the dynamic reconfigure. The derivated generic algorithm class must implement it.

Parameters:

config	an object with new configuration from all algorithm parameters defined in the config file.
level	integer referring the level in which the configuration has been changed.

Implements algorithm_base::IriBaseAlgorithm< DrawRectangleAlgorithm >.

Definition at line 94 of file draw_rectangle_alg_node.cpp.

cv::Mat DrawRectangleAlgNode::processImage ( cv::Mat image ) [private]

Remove border of the image.

This method removes the border of the image
