Abstract
In this paper, we propose a remote monitoring system of joint coordinates for comfort dummy in a passenger car. The dummy is designed to serve as a linkage structure for the lumbar joints. we can get rotation measurement information of each joints and calculate each joint's coordinate using homogeneous transformation matrices. In order to convert the dummy coordinates to the absolute coordinate in a passenger car, three vision cameras are attached on the eyes and forhead locations of the dummy and triangulation algorithm was adopted. This 3-dimensional stereo vision system capture a view when the dummy was seated at the driver's seat and calculate the location of the steering wheel in the passenger car by triangulation algorithm. This 3-D stereo vision system successfully capture the position of the steering wheel in a passenger car and the triangulation algorithm successfully convert the local coordinate informations of the dummy posture to absolute coordinate of the passenger car.
