Binocular structured light technology is widely employed in high-precision 3D reconstruction due to its reliability and accuracy. However, it has inherent limitations, including partial point cloud loss resulting from limited perspectives, occlusions, and uneven illumination. To address this issue, this study proposes a monocular–binocular fusion completion framework.

1. Introduction 1.1. Geometric Models of SAR Images The synthetic aperture radar (SAR) geometric model plays a foundational role in high-precision geolocation processes, encompassing geometric correction, stereo positioning, block adjustment, and three-dimensional reconstruction of SAR imagery [1,2,3,4]. Geometric models of SAR imagery are generally divided into two categories: rigorous and non-rigorous.
