Detailed Description

IntervalIntersector

This class receives streams of interval messages, sorted by end time within each stream. For each end time, it outputs the largest intervals contained in one interval of each stream. This class is general, but is designed to compute the intervals of time where a list of sensors were all stable at the same time, and can therefore be used together for calibration. The code assumes that start times of intervals are also non-decreasing. If not, it will output a reasonable answer though not an optimal one (it is impossible in that case to guarantee optimality since a later message can extend a previously output interval).

void IntervalIntersector::inputCallback ( const calibration_msgs::IntervalConstPtr &  interval_ptr, size_t  i  )

private

Interval message callback.

It puts the message on a queue. If all queues are non-empty, they are processed until one of them is empty.
