Abstract
A coordinate locating device comprising a support structure removably connectable to a wearable sensor device being worn by an individual. The support structure comprising a planar surface. The device includes a plurality of different fiducial marker components connected to the planar surface. The plurality of different fiducial marker components includes a set of fiducial markers connected to the planar surface in a non-collinear configuration relative to each other to define a three-dimensional (3D) space of pixels in an image. The plurality of different fiducial marker components includes a distance calibration fiducial marker connected to the planar surface and being configured to define a distance calibration length of pixels in the image, the distance calibration fiducial marker being perpendicular to the planar surface and defining a calibration length to locate a point of origin of motion sensing by the wearable sensor device. A system and method are also provided.
