This is a simple wrapper to <code><a rd-options="lidR:filter_poi" href="/link/filter_poi?package=TreeLS&version=2.0.2&to=lidR%3Afilter_poi" data-mini-rdoc="lidR:filter_poi::filter_poi">filter_poi</a></code> that takes as input relative values instead of absolute time stamps for filtering <code>LAS</code> object based on the gpstime. This function is particularly useful to check narrow intervals of point cloud frames from mobile scanning data.

High performance algorithms for manipulation of terrestrial 'LiDAR' (but not only) point clouds for use in research and forest monitoring applications, being fully compatible with the 'LAS' infrastructure of 'lidR'. For in depth descriptions of stem denoising and segmentation algorithms refer to Conto et al. (2017) <doi:10.1016/j.compag.2017.10.019>.
