使用ceres库的关键是构造costfunction,ceres官方搭建的costfunction,同样有一个类表示,名为PoseGraph3dErrorTerm,具体如下所示: classPoseGraph3dErrorTerm{public:PoseGraph3dErrorTerm(constPose3d&t_ab_measured,constEigen::Matrix<double,6,6>&sqrt_information):t_ab_measured_(t_ab_measured),sqrt_information_...

Existing skeleton-based 3D human pose estimation methods only predict joint positions. Although the yaw and pitch of bone rotations can be derived from joint positions, the roll around the bone axis remains unresolved. We present PoseGraphNet++ (PGN++), a novel 2D-to-3D lifting Graph Convolutio...

Hi, the pose graph optimization is only needed for loop closures. If you can do without loop closures, you could disable them with --no_loop_detection. To debug the "Cholesky failure" error, could you please check the CMake settings of your g2o build for BUILD_WITH_MARCH_NATIVE? It sho...
