ApproximateTime policy

Overview

This is a policy used by fkie_message_filters::Combiner to match messages coming on a set of topics, even if their time stamps do not match perfectly. It uses a modified version of the message_filters/ApproximateTime algorithm. Like its predecessor, the algorithm is not merely applying an epsilon to account for time differences, but tries to find the best possible match. Each set of grouped messages which are output by the policy, satisfies the following criteria:

Optional parameters:

Algorithm

The algorithm works as follows:
