Abstract
Three-dimensional target configurations attached to the head, neck, and pelvis of human volunteer subjects undergoing impact acceleration and vibration experiments are acquired by at least two cameras. Linear displacement and orientation parameters are derived from the digitized data film by a least squares algorithm. In order to minimize low frequency errors, it is necessary to calibrate individual high-speed cameras to determine points in the film plane. In addition, it is required to know how these cameras are located and oriented in the laboratory reference system. This paper will describe the procedure and the dedicated apparatus for camera calibration, discuss problems, and compare three surveying methods used to locate and determine camera orientation.
