Fields

double TOO_CLOSE_OBSTACLE {0.15}

Directions with collision-free distances below this threshold are not elegible.

double TARGET_SLOW_APPROACHING_DISTANCE {0.60}

Start to reduce speed when closer than this to target [m].

double OBSTACLE_SLOW_DOWN_DISTANCE {0.15}

Start to reduce speed when clearance is below this value ([0,1] ratio wrt obstacle reference/max distance)

double HYSTERESIS_SECTOR_COUNT {5}

Range of “sectors” (directions) for hysteresis over successive timesteps.

std::vector<double> factorWeights

See docs above.

std::vector<int32_t> factorNormalizeOrNot

0/1 to normalize factors.

std::vector<std::vector<int32_t>> PHASE_FACTORS

Factor indices [0,4] for the factors to consider in each phase 1,2,…N of the movement decision (Defaults: PHASE1_FACTORS=0 1 2, PHASE2_FACTORS= 3 4`)

std::vector<double> PHASE_THRESHOLDS

Phase 1,2,N-1…

scores must be above this relative range threshold [0,1] to be considered in phase 2 (Default: 0.75)

bool LOG_SCORE_MATRIX {false}

(default:false, to save space)

double clearance_threshold_ratio {0.05}

Ratio [0,1], times path_count, gives the minimum number of paths at each side of a target direction to be accepted as desired direction.

double gap_width_ratio_threshold {0.25}

Ratio [0,1], times path_count, gives the minimum gap width to accept a direct motion towards target.

Methods

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

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

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,...
