Via #OPG_AO: Robust trajectory triangulation for UAV visual localization via iteratively reweighted least squares https://bit.ly/4jWSeXc #ImageMetrics #ThreeDimensionalReconstruction 💡⚛️

A 3D plot shows various trajectories labeled with different styles and colors. The "target" path is marked with turquoise star shapes. The "observer" path is shown with small blue circles. "PLLs" utilizes a green dash-dot line, "Optim" with a dashed magenta line, and "IRLS" indicated with a solid blue triangle. The axes are labeled x(m), y(m), and z(m) with numbers ranging from 0 to 100. The legend is located in the top right.
