Detailed Description

Scanline Grid.

A grid as scanline points. The crossings of the lines are the scanline points.

Definition at line 36 of file grid.h.

Constructor & Destructor Documentation

firevision::ScanlineGrid::ScanlineGrid	(	unsigned int	width,
		unsigned int	height,
		unsigned int	offset_x,
		unsigned int	offset_y,
		ROI *	roi = `NULL`,
		bool	horizontal_grid = `true`
	)

Constructor.

Parameters:

	width	width of grid
	height	height of grid
	offset_x	x offset between lines
	offset_y	y offset between lines
	roi	the grid will only be calculated within the roi (if NULL the roi will be from 0,0 to width,height). The object will be deleted by ScanlineGrid!
	horizontal_grid	if true x will be increased before y

Member Function Documentation

bool firevision::ScanlineGrid::finished ( ) [virtual]

Check if all desired points have been processed.

Returns:: true if all pixels that the model defines have been iterated.

Implements firevision::ScanlineModel.

Definition at line 147 of file grid.cpp.

Referenced by firevision::GradientClassifier::classify().

unsigned int firevision::ScanlineGrid::get_margin ( ) [virtual]

Get margin around points.

Models that do not use margins shall return zero. It shall be guaranteed that in this margin region around a point there is no other point that has been or will be returned in a full iteration.

Returns:: margin around a point.

Implements firevision::ScanlineModel.

Definition at line 169 of file grid.cpp.

const char * firevision::ScanlineGrid::get_name ( ) [virtual]

Get name of scanline model.

Returns:: name of scanline model.

Implements firevision::ScanlineModel.

Definition at line 162 of file grid.cpp.

point_t firevision::ScanlineGrid::operator* ( ) [virtual]

Get the current coordinate.

Returns:: current point in image that is shall be processed.

Implements firevision::ScanlineModel.

Definition at line 74 of file grid.cpp.

point_t * firevision::ScanlineGrid::operator++ ( int ) [virtual]

Prefix ++ operator.

Advances to the next point but returns the old point.

Returns:: pointer to next point

Implements firevision::ScanlineModel.

Definition at line 139 of file grid.cpp.

point_t * firevision::ScanlineGrid::operator++ ( ) [virtual]

Postfix ++ operator.

Advances to the next point and returns the new point.

Returns:: pointer to new point

Implements firevision::ScanlineModel.

Definition at line 132 of file grid.cpp.

point_t * firevision::ScanlineGrid::operator-> ( ) [virtual]

Get pointer to current point.

Returns:: pointer to current point

void firevision::ScanlineGrid::reset ( ) [virtual]

Reset model.

Resets the set of processed points.

void firevision::ScanlineGrid::set_robot_pose	(	float	x,
		float	y,
		float	ori
	)			`[virtual]`

Set the robot's pose.

Parameters:

	x	robot's x coordinate on field in meters
	y	robot's y coordinate on field in meters
	ori	robot's orientation. Looking towards the opponent goal is zero rad, with positive values pointing to the right, negative to the left.

void firevision::ScanlineGrid::set_roi ( ROI * roi = NULL ) [virtual]

Set the region-of-interest.

If not NULL the scanlines gets only calculated within the ROI

Parameters:

roi
