摘　　要：面向空间近距离操作的相对位姿测量系统(RPS)是对目标进行距离测量、位姿测量、三维重构及光学成像的有效方式。针对高精度一体化位姿测量需求,文章提出了融合激光雷达测距的单目视觉位姿测量系统,可同时具备目标距离、方位测量及三维成像等能力。经过在轨应用验证,结果表明:方位测角精度和位姿测量精度等关键指标均优于预期值,该系统主要功能性能可满足空间操作实际应用需求,可以为未来空间机动平台的目标测量系统研制提供参考。The relative target pose measurement system(RPS)for close range space manipulation is considered as an effective way for distance measurement,pose measurement,three-dimensional reconstruction,and optical imaging of target in space.In response to the demand for high-precision integrated pose measurement,this paper proposes a monocular visual pose measurement system that integrates laser radar ranging,which can simultaneously have the ability to measure target distance,orientation,and 3D imaging of targets,After in-orbit verification,the key indicators such as azimuth angle measurement accuracy and pose accuracy are beyond expectations,and the main functional performance can meet the practical application requirements of space manipulation.It can provide reference for the development of target measurement system for future space maneuvering platforms.
