Related work Multi-view 3D human pose: Markerless motion capture has been investigated in computer vision for a decade. These are effective because fast linear algorithms exist for the computation of the re-lationships, allowing their computation to form the kernel of RANSAC-based matching algorithms. RPC cameras are approximated with perspective cameras, which then are bundle-adjusted by our pipline. The resolution of these images is around 30 cm per pixel. Exercises If you perform Multi-view Stereo on these images and cameras, the reconstructed point cloud will be in a local ENU coordinate system. We provide this accompanying toolset [VisSatToolSet] to convert the points' coordinates to the global coordinate system, i.e., (UTM east, UTM north, altitude), and report its accuracy by comparing to the ground-truth. github.io/mvpose/.
