1. Foreword In the past two years, the requirements and difficulty of graduation projects and graduation defenses have continued to increase. Traditional graduation projects lack innovation and highlights, and often fail to meet the requirements for graduation defenses. In the past two years, junior students and junior students have constantly told Senior Xiaohong to do […]

Install orb_slam2, vins_mono, orb_slam3 in ubuntu18melodic environment to run the euroc data set and use evo to evaluate
Foreword Recently, I used orb_slam2 modified by Dr. Gao Xiang to generate a dense point cloud, and then used an octree to generate a two-dimensional raster map for navigation. However, the effect of the created map is not very good and the drift is too serious. On the left is the image generated by cartographer, […]

In Sarscape version 5.6, external control points are imported, precise orbit files are written, and GACOS is used for atmospheric phase.
PART1: Import external GCP points into SARscape for orbital refinement https://www.cnblogs.com/enviidl/p/16524645.html During SAR processing, GCP point files are sometimes added. The control points used in SAR processing are divided into two categories: geometric control points (Geometry GCP) used to correct geographical location and control points (Refinement GCP) used for orbit refinement. . Orbital refinement control […]
