摘要

The Rashid-1 lunar rover represented the first attempt by the United Arab Emirates to explore the surface of the Moon. The mission of Rashid-1 was supposed to begin only a few hours following the planned landing by the iSpace Hakuto-R M1 lunar lander inside the Atlas crater of the Moon. Unfortunately, the lander was unable to successfully complete the landing maneuver and it crashed on the surface of the Moon destroying both itself and its payloads in the process. In this paper, we present the characterization of the optical image acquisition systems onboard the Rashid-1 rover which consisted of two wide-field ( 82 ∘ × 82 ∘ $82^{\circ } \times 82^{\circ }$ ) identical cameras aptly named CAM-1 and CAM-2 and mounted on the front and back of the rover respectively. Additionally, a third high resolution optical imager (CAM-M) with a spatial resolution of approximately 27 μm/pixel was placed on the front of the rover and was tasked with obtaining what would have been, at that time, the highest resolution in-situ images ever taken of the lunar regolith. We discuss the basic calibration processes such as the thermal, radiometric, color, distortion and perspective corrections of the three optical systems. We also provide an overview of both the onboard as well as the ground processing steps that were set up to receive and examine the images the rover would have sent from the lunar surface.
