Public Attributes | |
TLikelihoodMethod | likelihoodMethod |
The selected method to compute an observation likelihood. | |
float | LF_stdHit |
[LikelihoodField] The laser range "sigma" used in computations; Default value = 0.35 | |
float | LF_zHit |
[LikelihoodField] Ratios of the hit/random components of the likelihood; Default values=0.95/0.5 | |
float | LF_zRandom |
float | LF_maxRange |
[LikelihoodField] The max. | |
uint32_t | LF_decimation |
[LikelihoodField] The decimation of the points in a scan, default=1 == no decimation. | |
float | LF_maxCorrsDistance |
[LikelihoodField] The max. | |
bool | LF_alternateAverageMethod |
[LikelihoodField] Set this to "true" ot use an alternative method, where the likelihood of the whole range scan is computed by "averaging" of individual ranges, instead of by the "product". | |
float | MI_exponent |
[MI] The exponent in the MI likelihood computation. | |
uint32_t | MI_skip_rays |
[MI] The scan rays decimation: at every N rays, one will be used to compute the MI: | |
float | MI_ratio_max_distance |
[MI] The ratio for the max. | |
bool | rayTracing_useDistanceFilter |
[rayTracing] If true (default), the rayTracing method will ignore measured ranges shorter than the simulated ones. | |
int32_t | rayTracing_decimation |
[rayTracing] One out of "rayTracing_decimation" rays will be simulated and compared only: set to 1 to use all the sensed ranges. | |
float | rayTracing_stdHit |
[rayTracing] The laser range sigma. | |
int32_t | consensus_takeEachRange |
[Consensus] The down-sample ratio of ranges (default=1, consider all the ranges) | |
float | consensus_pow |
[Consensus] The power factor for the likelihood (default=5) | |
std::vector< float > | OWA_weights |
[OWA] The sequence of weights to be multiplied to of the ordered list of likelihood values (first one is the largest); the size of this vector determines the number of highest likelihood values to fuse. | |
bool | enableLikelihoodCache |
Enables the usage of a cache of likelihood values (for LF methods), if set to true (default=false). |
mrpt::slam::COccupancyGridMap2D::TLikelihoodOptions::TLikelihoodOptions | ( | ) |
Initilization of default parameters.
void mrpt::slam::COccupancyGridMap2D::TLikelihoodOptions::dumpToTextStream | ( | CStream & | out | ) | const [virtual] |
This method must display clearly all the contents of the structure in textual form, sending it to a CStream.
Implements mrpt::utils::CLoadableOptions.
void mrpt::slam::COccupancyGridMap2D::TLikelihoodOptions::loadFromConfigFile | ( | const mrpt::utils::CConfigFileBase & | source, |
const std::string & | section | ||
) | [virtual] |
This method load the options from a ".ini" file.
Only those parameters found in the given "section" and having the same name that the variable are loaded. Those not found in the file will stay with their previous values (usually the default values loaded at initialization). An example of an ".ini" file:
[section] resolution=0.10 ; blah blah... modeSelection=1 ; 0=blah, 1=blah,...
Implements mrpt::utils::CLoadableOptions.
