The DIMS project (Dark matter and Interstellar Meteoroid Study) is an international collaboration with a twofold scientific goal: the search for hypothetical macroscopic dark matter candidates and the study of meteoroids of interstellar origin. To pursue these objectives, DIMS deployed highly sensitive CMOS cameras, that were operated from 2021 to 2025 in central Japan and at the Telescope Array site in Utah.
In this contribution we present the architecture of the pipeline developed for the analysis of DIMS observations of meteor events, that includes custom astrometry and elliptical aperture photometry, together with the adaptation of the PRISMA fireball network pipeline to the DIMS case. We discuss the preliminary results of multi-station triangulation, atmospheric dynamic model, and reconstructions of pre-atmospheric orbits of a selected sample of events. In particular, we focus on the search of interstellar meteor candidates and the assessment of measurement uncertainties.
