Dataset construction and quality assessment of on-board compression for lunar orbiter optical images — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: In lunar exploration missions, obtaining high-resolution optical imagery data from lunar orbiter cameras is crucial for both scientific research and engineering tasks. However, due to the limitations of satellite design, such as onboard storage capacity and downlink bandwidth constraints, satellite imagery typically needs to be compressed onboard prior to transmission. Before satellite launch, it is essential to test the parameters related to onboard compression, and the construction of compression test datasets plays a vital role in this procedure. In this study, a high-resolution optical imagery dataset specifically designed for lunar scenes is constructed to evaluate the onboard compression quality of lunar orbiter images. The dataset considers the information on lunar scenarios, including lunar time phase, illumination conditions and topography characteristics. We performed a quality assessment on the dataset. The results indicate that as the compression ratio increases, the image Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
