| 发明名称 | 3D motion recognition method and apparatus | ||
| 摘要 | Disclosed are a three-dimensional motion recognition method and an apparatus using a motion template method and an optical flow tracking method of feature points. The three dimensional (3D) motion recognition method through feature-based stereo matching according to an exemplary embodiment of the present disclosure includes: obtaining a plurality of images from a plurality of cameras; extracting feature points from a single reference image; and comparing and tracking the feature points of the reference image and another comparison image photographed at the same time using an optical flow method. | ||

| 主权项 | 1. A three dimensional (3D) motion recognition method through feature-based stereo matching, comprising: obtaining a plurality of images from a plurality of cameras; extracting feature points from a single reference image; and comparing and tracking the feature points of the reference image and another comparison image photographed at the same time using an optical flow method; wherein the optical flow method is capable of modifying a size and a shape of a window used in the optical flow method by using previous information. | ||
