Member Typedef Documentation

typedef vpImage<unsigned char> visp_tracker::TrackerViewer::image_t

ViSP image type.

Definition at line 34 of file tracker-viewer.hh.

typedef message_filters::sync_policies::ApproximateTime< sensor_msgs::Image, sensor_msgs::CameraInfo, geometry_msgs::PoseWithCovarianceStamped, visp_tracker::MovingEdgeSites, visp_tracker::KltPoints > visp_tracker::TrackerViewer::syncPolicy_t

Synchronization policy.

This is used to make sure that the image, the object position and the moving edge sites are synchronized. This may not be the case as these informations are published on different topics. The approximate time allows light differences in timestamps which are not critical as this is only a viewer.
