Class Documentation

class Rosbag2Dataset : public mola::RawDataSourceBase, public mola::OfflineDatasetSource, public mola::Dataset_UI

RawDataSource for datasets in rosbag2 format.

It reads a rosbag2 file, and exposes it as a dataset with N entries, N being the number of messages in the bag. Reading them via the offline API (OfflineDatasetSource) returns empty shared_ptr observations for those messages that do not have a direct mapping to mrpt::obs classes. The dataset can be also played in an online (real-time, or with a custom time wrapping) fashion via the RawDataSourceBase API.

See example configuration files to see how to define what topics to publish, and how to optionally override the sensor poses in the local robot frame.
