Abstract: A training data augmentation method for three-dimensional (3D) pose estimation includes collecting foot coordinates of each of persons appearing in a two-dimensional image, estimating a ground plane in a three-dimensional space based on the collected foot coordinates, generating three-dimensional pose data by moving or rotating at least one person or moving or rotating the ground plane based on two basis vectors perpendicular to a normal vector of the ground plane, mapping the 3D pose data to two-dimensional pose data based on a focal length of a camera obtained by capturing the two-dimensional image and a principal point of coordinates of the two-dimensional image, and acquiring a pair of the 3D pose data and two-dimensional pose data as training data.
