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

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

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 * RectificationLutInfoBlock::lut_data (  ) 

Get raw LUT data.

Use this to access the LUT.

Returns:
pointer to raw LUT data

void 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
