Fields¶

bool useOriFilter {true}

Whether or not use the filter based on orientation test.

double oriThreshold {0.2}

The threshold for the orientation test.

bool useDepthFilter {true}

Whether or not use the filter based on the depth test.

double matchingThreshold {1e4}

The absolute threshold in descriptor distance for considering a match.

double matchingRatioThreshold {0.5}

The ratio between the two lowest distances threshold for considering a match.

uint32_t lowScl1 {0}

The lowest scales in the two features to be taken into account in the matching process.

uint32_t highScl1 {6}

The highest scales in the two features to be taken into account in the matching process.

uint32_t searchAreaSize {20}

Size of the squared area where to search for a match.

uint32_t lastSeenThreshold {10}

The allowed number of frames since a certain feature was seen for the last time.

uint32_t timesSeenThreshold {5}

The minimum number of frames for a certain feature to be considered stable.

uint32_t minFeaturesToFind {30}

The minimum number of features allowed in the system.

If current number is below this value, more features will be found.

uint32_t minFeaturesToBeLost {5}

The minimum number of features allowed in the system to not be considered to be lost.

Construction¶

TMultiResDescMatchOptions()

Default constructor.

Methods¶

virtual void loadFromConfigFile(const mrpt::config::CConfigFileBase& cfg, const std::string& section)

Load all the params from a config source, in the format described in saveToConfigFile()

virtual void saveToConfigFile(mrpt::config::CConfigFileBase& target, const std::string& section) const

This method saves the options to a “.ini”-like file or memory-stored string list.
