Detailed Description

Recitification Lookup Table Block.

This class defines a rectification lookup table info block that can be used to define a LUT that maps rectified to unrectified pixels.

Constructor & Destructor Documentation

firevision::RectificationLutInfoBlock::RectificationLutInfoBlock	(	uint16_t	width,
		uint16_t	height,
		uint8_t	camera
	)

Constructor.

Parameters:

width	width of the image
height	height of the image
camera	camera identifier, see rectinfo_camera_t

Definition at line 47 of file rectinfo_lut_block.cpp.

References firevision::FireVisionDataFileBlock::_data, firevision::_rectinfo_lut_16x16_block_header_t::height, and firevision::_rectinfo_lut_16x16_block_header_t::width.

firevision::RectificationLutInfoBlock::RectificationLutInfoBlock ( FireVisionDataFileBlock * block )

Copy Constructor.

It is assumed that the block actually is a rectification LUT info block. Check that before calling this method.

Parameters:

block block to copy

Member Function Documentation

rectinfo_lut_16x16_entry_t * firevision::RectificationLutInfoBlock::lut_data ( )

Get raw LUT data.

Use this to access the LUT.

Returns:: pointer to raw LUT data

Definition at line 147 of file rectinfo_lut_block.cpp.

void firevision::RectificationLutInfoBlock::mapping	(	uint16_t	x,
		uint16_t	y,
		uint16_t *	to_x,
		uint16_t *	to_y
	)

virtual

Get mapping (to_x, to_y) for (x, y).

This can be used as a general method to access the RectificationInfoBlock mapping. For many models there may be a better (faster) way to access the mapping information. It performance matters (and it most probably will) exploit this and use the provided shortcut.

Parameters:

x	X pixel coordinate to get mapping for
y	Y pixel coordinate to get mapping for
to_x	Upon return contains the X pixel coordinate of the unrectified image
to_y	Upon return contains the Y pixel coordinate of the unrectified image
