3D motion evaluation apparatus, 3D motion evaluation method, and program

摘要

The three-dimensional motion evaluation apparatus 100 includes a two-dimensional image corresponding point search unit 101 and a three-dimensional motion optimization unit 102. The two-dimensional image corresponding point search unit 101 searches for a dense two-dimensional corresponding point between subsequent frames and outputs a two-dimensional motion in pixel units between frame images. The 3D motion optimization unit 102 uses the depth of a single point observed in a single frame to obtain accurate 3D motion in the real world. By optimizing the error and optimizing the error of the two-dimensional motion in this pixel unit, the three-dimensional real world motion of the object is calculated.
