ToF相机在空间非合作目标近距离测量中的应用

针对已有测量手段在空间非合作目标近距离测量中的问题，本文主要分析了ToF（Time-of-Flight）相机在空间应用中的可能性。首先总结了空间非合作目标近距离测量现状及已有测量手段；随后介绍了ToF相机的原理及发展，并以非合作目标典型特征为例对其性能指标进行分析；接着将ToF相机与现有空间近距离测量手段进行性能比较；并对其中的关键技术进行梳理；最后对ToF相机的未来发展趋势及其在空间中的应用进行展望。

Application of Time of Flight Camera for Relative Measurement of Non Cooperative Target in Close Range

According to the problem existing the measurement instruments in the measurement of the non-cooperative target in close range, this paper analyzes the possibility of the time-of-flight (ToF) camera in space application. Firstly, the research status of the relative measurement of the non-cooperative targets in close range and the existing measurement methods are summarized. Secondly, the principle and development of the ToF cameras are introduced and the typical feature of the non-cooperative targets is chosen as an example to analyze the performance indices of the ToF cameras. Thirdly, the ToF cameras and the existing measurement methods in close range are compared in terms of the performance and the key techniques involved are sorted out. Finally, the development trends of the ToF cameras and their applications in space are prospected.
