The invention provides a head posture data acquisition system and method. The system comprises a first camera shooting unit, an inertial measurement unit and a second camera shooting unit, the inertial measurement unit is worn on the head of a user and used for collecting posture data of the head of the user. The first camera shooting unit and the inertial measurement unit are fixedly arranged together, and are used for collecting image data of an orientation area of the inertial measurement unit; the first camera unit faces the direction back to the head of the user; the second camera shooting unit is arranged at a position directly facing the head of the user and is used for collecting image data of a facing area of the user; the first camera unit is used for calibrating a target conversion relation between a coordinate system where the inertial measurement unit is located and a coordinate system where the second camera unit is located so as to determine posture data of the head of the user under the coordinate system where the second camera unit is located. The method can effectively obtain the training data of the head posture, and guarantees the training precision of the head posture estimation model.

    本发明提供了一种头部姿态数据采集系统及方法,该系统包括:第一摄像单元、惯性测量单元和第二摄像单元;惯性测量单元佩戴于用户头部,用于采集用户头部的姿态数据;第一摄像单元与惯性测量单元固设在一起,用于采集其朝向区域的图像数据;第一摄像单元的朝向为背对用户头部的方向;第二摄像单元设置于正对所述用户头部的位置,用于采集其朝向区域的图像数据;第一摄像单元用于对惯性测量单元所在坐标系与第二摄像单元所在坐标系之间的目标转换关系进行标定以便于确定第二摄像单元所在坐标系下用户头部的姿态数据。本发明可有效获取头部姿态的训练数据,保证头部姿态估计模型的训练精度。
