A Practical Geometric Calibration Method for a large-Scale High-Precision Measurement System in 3-D space for Human Posture

摘要

A Practical Geometric Calibration Method for a large-Scale High-Precision 3-D Position Sensing System for Human Posture is developed; the proposed method enables us easily to set up the sensing system; then the applicable areas and circumstances are extended extremely. In this Paper, we try to consider 3-D position sensing system with 1-D mark direction sensitive devices, which can be used to determine the position of three bright spot fixed to Human head in a large-Scale 3-D space. This approach, is based on an engineering mathematical closed form technique for the perspective of determining the related parameter to the formula of the point of interest in 3-D space with possible large scale extension, with a simple automatically calibration arrangement for the sensing system placed in the measuring space related to 7 referential point. We believe that this practical system will be very helpful to human related movement research.
