WebOct 7, 2024 · To do so, first we crop the recovered Single-Image depth map – to fit the ROI active tracks, backproject it to an organized point cloud and rotate it using the camera pose to align it with gravity. We then estimate the object coarse height by averaging the height values of all points within the target bounding box. http://vigir.missouri.edu/~gdesouza/Research/Conference_CDs/ACCV_2014/pages/PDF/755.pdf
