Function Documentation

ExtractLaserLineFromImage() [1/2]

void ExtractLaserLineFromImage	(	const Image &	monoImage,
		LineExtractionParameters	parameters,
		int	lineOut,
		Image &	rangeMap )

Extracts the laser line from given monoImage and stores it to lineOut of the previously allocated range map.

Attention

The rangeMap must be allocated correctly. The following constraints must be met:

• The width of monoImage and rangeMap must be equal.
• The height of rangeMap must be greater than lineOut.
• The data type of rangeMap must be float or double.

using namespace Cvb::Foundation::Metric::LaserLineExtraction;
 
// load image with laser line
auto image = Cvb::Image::Load(L"image.tif");
 
// allocate range map
int numberOfLines = 100;
auto rangeMap = std::make_unique<Cvb::Image>(image->Width(), numberOfLines, 1, Cvb::DataType::Float32Bpp());
 
// extract laser line from image and store it to 5th row in range map
int iline = 5;
LineExtractionParameters parameters = { PeakLocalizationMethod::CoG, 0.0, FIRFilter::None, 5 };
ExtractLaserLineFromImage(*image, parameters, iline, *rangeMap);

Parameters

[in]	monoImage	Mono image with laser line to be extracted.
[in]	parameters	Parameters for laser line extraction.
[in]	lineOut	Line in range map (or intensity image), where results will be stored.
[out]	rangeMap	Range map image where results are stored. It has to be allocated correctly.

Exceptions

Any	exception derived from std::exception including CvbException.

ExtractLaserLineFromImage() [2/2]

void ExtractLaserLineFromImage	(	const Image &	monoImage,
		LineExtractionParameters	parameters,
		int	lineOut,
		Image &	rangeMap,
		Image &	intensityImage )

Extracts the laser line from given monoImage and stores it to lineOut of the previously allocated range map.

Intensity values are additionally stored to intensityImage.

Attention

The rangeMap and intensityImage must be allocated correctly. The following constraints must be met:

• The width of monoImage and rangeMap (and intensityImage) must be equal.
• The height of rangeMap (and intensityImage) must be greater than lineOut.
• The data type of rangeMap (and intensityImage) must be float or double.

  using namespace Cvb::Foundation::Metric::LaserLineExtraction;
 
  // load image with laser line
  auto image = Cvb::Image::Load(L"image.tif");
 
  // allocate range map and intensity image
  int numberOfLines = 100;
  auto rangeMap = std::make_unique<Cvb::Image>(image->Width(), numberOfLines, 1, Cvb::DataType::Float32Bpp());
  auto intensityImage = std::make_unique<Cvb::Image>(image->Width(), numberOfLines, 1,
Cvb::DataType::Float32Bpp());
 
  // extract laser line from image and store it to 5th row in range map
  int iline = 5;
  LineExtractionParameters parameters = { PeakLocalizationMethod::CoG, 0.0, FIRFilter::None, 5 };
  ExtractLaserLineFromImage(*image, parameters, iline, *rangeMap, *intensityImage);

Parameters

[in]	monoImage	Mono image with laser line to be extracted.
[in]	parameters	Parameters for laser line extraction.
[in]	lineOut	Line in range map (or intensity image), where results will be stored.
[out]	rangeMap	Range map image where results are stored. It has to be allocated correctly.
[out]	intensityImage	Image where intensity values are stored. It has to be allocated correctly.

Exceptions

Any	exception derived from std::exception including CvbException.
