BIWI 头部姿态估计数据集
收藏资源简介:
BIWI 又称 Biwi Kinect Head Pose Database,是一个用于研究头部姿态估计的数据集。该数据集由 1.5 万张图像组成,共有 20 位志愿者参加了数据的收集,6 名为女性,14 名为男性,其中 4 人被记录了两次。数据的每一帧都有一幅深度图像、相应的 rgb 图像(像素均为 640*480)以及标注。头部姿势范围包括了 +- 75° 偏转和 +- 60° 俯仰。 ground truth 以头部 3D 位置和旋转的形式提供。
BIWI, also referred to as the Biwi Kinect Head Pose Database, is a dataset designed for head pose estimation research. It comprises 15,000 images collected from 20 volunteers, among whom 6 are female and 14 are male, with 4 participants being recorded twice. Each frame contains a depth image, the corresponding RGB image with a resolution of 640×480 pixels, and corresponding annotations. The head pose ranges cover ±75° of yaw and ±60° of pitch. The ground truth is provided in the form of the 3D position and rotation of the head.
