alternativeLaneletPoses()

auto traffic_simulator::lanelet_wrapper::pose::alternativeLaneletPoses

(

const LaneletPose &

reference_lanelet_pose

)

-> std::vector<LaneletPose>

Retrieves alternative lanelet poses based on the reference lanelet pose.

This method computes alternative lanelet poses in the previous and next lanelets relative to a given reference lanelet pose. It recursively explores the neighboring lanelets until no further alternatives are found. The decision of whether a pose belongs to a previous or next lanelet is based on the s value of the reference pose:

• If s is negative, the pose is assumed to be on the previous lanelet.
• If s exceeds the lanelet length, the pose is assumed to be on the next lanelet.
• If s is within the valid range of the lanelet (from 0 to the lanelet's length), the reference lanelet pose is returned directly.

Parameters

reference_lanelet_pose

The reference pose on a lanelet, used to determine its position and compute alternatives in neighboring lanelets.

Returns

A vector of alternative LaneletPose objects representing poses in the neighboring lanelets, or the reference pose if no alternatives are found.

Note

If s value under 0, it means this pose is on the previous lanelet.

If s value overs it's lanelet length, it means this pose is on the next lanelet.

If s value is in range [0,length_of_the_lanelet], return lanelet_pose.

If s value under 0, it means this pose is on the previous lanelet.

If s value overs it's lanelet length, it means this pose is on the next lanelet.

If s value is in range [0,length_of_the_lanelet], return lanelet_pose.

canonicalizeLaneletPose() [1/2]

auto traffic_simulator::lanelet_wrapper::pose::canonicalizeLaneletPose

(

const LaneletPose &

lanelet_pose

)

-> std::tuple< std::optional< LaneletPose >, std::optional< lanelet::Id >>

Canonicalizes a given LaneletPose by adjusting the longitudinal position (s) to ensure it lies within the bounds of the specified lanelet. If the position is out of bounds, it traverses to previous or next lanelets to find the canonicalized position.

If the provided pose has a longitudinal position (s) less than 0, the function traverses to previous lanelets until a valid position is found or no previous lanelets exist.

If the longitudinal position (s) exceeds the length of the current lanelet, the function traverses to next lanelets until the position is valid or no next lanelets exist.

Parameters

lanelet_pose

The input LaneletPose to canonicalize, containing a lanelet ID and longitudinal position (s).

Returns

A tuple where:

• The first element is an optional canonicalized LaneletPose (std::nullopt if canonicalization fails).
• The second element is an optional lanelet ID where the process stopped (std::nullopt if successful).
