SPARK2022 Challenge aims to design data-driven approaches for spacecraft detection and trajectory estimation. SPARK will utilise data synthetically simulated with a state-of-the-art rendering engine in addition to data collected from the Zero-Gravity Laboratory (Zero-G Lab) facility at the University of Luxembourg. Stream 1 – Spacecraft Detection Detecting space objects: localize and classify the object by estimating its bounding box and label. Stream 2 – Spacecraft Trajectory Estimation Leveraging the knowledge of temporal data to estimate the 6DoF pose of the spacecraft.
