The invention discloses a motion tracking system for tracking the motion of a subject in an environment, and the system comprises an imaging device adapted to be worn by the subject; an accelerometeradapted to be worn by the subject; and a processor configured to receive a series of images of the environment captured by the imaging device and to form, in dependence on the images an estimate of the subject's position in the environment, and to receive acceleration data from the accelerometer and to, form an estimate of the motion of a part of the subject's body carrying the accelerometer in dependence on the acceleration data and the estimated position. 一种跟踪受试体在环境中的运动的运动跟踪系统，该系统包括：被适配为由所述受试体穿戴的成像设备；被适配为由所述受试体穿戴的加速度计；以及处理器，其被配置为接收由所述成像设备捕获的所述环境的一系列图像，并根据所述图像形成所述受试体在所述环境中的位置的估计，以及从所述加速度计接收加速度数据，并根据所述加速度数据和所估计的位置，形成携带所述加速度计的所述受试体的身体的部位的运动的估计。
