摘要： A method for capturing motion of an object, the method comprising: installing at least one marker on the object; bringing the object having the at least one marker installed thereon in an acquisition volume; arranging at least two event-based light sensors such that respective fields of view of the at least two event-based light sensors cover the acquisition volume, wherein each event-based light sensor has an array of pixels; receiving events asynchronously from the pixels of the at least two event-based light sensors depending on variations of incident light from the at least one marker sensed by the pixels; and processing the events to position the at least one marker within the acquisition volume and capture motion of the object.
