Feature class
Sparse feature class used to collect measurements.
Contents
- Reference
This feature class allows for holding of all tracking information for a given feature. Each feature has a unique ID assigned to it, and should have a set of feature tracks alongside it. See the FeatureDatabase class for details on how we load information into this, and how we delete features.
Public functions
- void clean_old_measurements(const std::vector<double>& valid_times)
- Remove measurements that do not occur at passed timestamps.
- void clean_invalid_measurements(const std::vector<double>& invalid_times)
- Remove measurements that occur at the invalid timestamps.
- void clean_older_measurements(double timestamp)
- Remove measurements that are older then the specified timestamp.
Public variables
- size_t featid
- Unique ID of this feature.
- bool to_delete
- If this feature should be deleted.
- std::unordered_map<size_t, std::vector<Eigen::VectorXf>> uvs
- UV coordinates that this feature has been seen from (mapped by camera ID)
- std::unordered_map<size_t, std::vector<Eigen::VectorXf>> uvs_norm
- UV normalized coordinates that this feature has been seen from (mapped by camera ID)
- std::unordered_map<size_t, std::vector<double>> timestamps
- Timestamps of each UV measurement (mapped by camera ID)
- int anchor_cam_id
- What camera ID our pose is anchored in!! By default the first measurement is the anchor.
- double anchor_clone_timestamp
- Timestamp of anchor clone.
- Eigen::Vector3d p_FinA
- Triangulated position of this feature, in the anchor frame.
- Eigen::Vector3d p_FinG
- Triangulated position of this feature, in the global frame.
Function documentation
void ov_core::
Remove measurements that do not occur at passed timestamps.
| Parameters | |
|---|---|
| valid_times | Vector of timestamps that our measurements must occur at |
Given a series of valid timestamps, this will remove all measurements that have not occurred at these times. This would normally be used to ensure that the measurements that we have occur at our clone times.
void ov_core::
Remove measurements that occur at the invalid timestamps.
| Parameters | |
|---|---|
| invalid_times | Vector of timestamps that our measurements should not |
Given a series of invalid timestamps, this will remove all measurements that have occurred at these times.
void ov_core::
Remove measurements that are older then the specified timestamp.
| Parameters | |
|---|---|
| timestamp | Timestamps that our measurements must occur after |
Given a valid timestamp, this will remove all measurements that have occured earlier then this.
