Recording posture and movement is important for determining risk of musculoskeletal injury in the workplace, but existing motion capture systems are not suited for field work. Estimates of the 3-D relative positions of four 0.10 m cubes from the Kinect were compared to estimates from a Vicon motion capture system to determine whether the hardware sensing components were sensitive enough to be used as a portable 3-D motion capture system for workplace ergonomic assessments. The root-mean-squared errors (SD) were 0.0065 m (0.0048 m), 0.0109 m (0.0059 m), 0.0057 m (0.0042 m) in the x, y and z directions (with x axis to the right, y axis away from the sensor and z axis upwards). These data were collected over a range of 1.0-3.0m from the device covering a field of view of 54.0 degrees horizontally and 39.1 degrees vertically. Requirements for software, hardware and subject preparation were also considered to determine the usability of the Kinect in the field.
记录姿势和运动对于确定工作场所肌肉骨骼损伤的风险很重要，但现有的运动捕捉系统不适合现场工作。本研究比较了 Kinect 对四个 0.10 米立方的 3D 相对位置的估计与 Vicon 运动捕捉系统的估计，以确定硬件感应组件是否足够灵敏，可作为用于工作场所人体工程学评估的便携式 3D 运动捕捉系统。x、y 和 z 方向的均方根误差（SD）分别为 0.0065 米（0.0048 米）、0.0109 米（0.0059 米）和 0.0057 米（0.0042 米）。这些数据是在距离设备 1.0-3.0 米的范围内采集的，设备的水平视场为 54.0 度，垂直视场为 39.1 度。还考虑了软件、硬件和主体准备的要求，以确定 Kinect 在现场的可用性。
