Studies on 3D Reconstruction Camera Based on Monocular Vision

针对飞行器执行在轨服务获取空间多维图像的需求,提出了基于单目视觉的三维重构相机技术,利用基于亮度法体素着色原理实现空间目标的三维重构。搭建地面试验,设计模拟圆轨道和椭圆轨道多种试验,验证了在200 m范围内伴飞状态下,实现对目标的高分辨率三维重构图像,重构精度为0.105 m,为识别空间目标特征部位奠定技术基础。

In order to meet the needs of aircraft to obtain multi-dimensional space images when performing on-orbit service,the 3D reconstruction camera technology based on monocular vision was put forward,and 3D reconstruction of space objects was realized by using voxel coloring principle based on brightness method.The ground experiment was set up,and various experiments simulating circular orbit and elliptical orbit were designed.It was verified that the high-resolution 3D reconstructed image of the target could be realized in the state of accompanying flight within 200 m,and the reconstruction accuracy was 0.105 m,which laid a technical foundation for identifying the characteristic parts of the space target.
