Abstract
In this paper we describe advanced contactless method for the precise posture head measurement using two digital cameras with a special stand. Three main important requirements are needed for the successful measurement.
The method is designed for use in neurology to discover relationships between some neurological disorders (such as disorders of vestibular system) and postural head alignment. The main goal of this study is to compare possibilities of the method with callibration. and validation tests.
It means with the special accurate protractor in case of the head inclination and head flexion/extension and with the stepper motor including planet gearbox in case of the head rotation. The results are presented for all cases.
It was experimentally checked that the accuracy of this method in order of tenths of degrees and therefore this method satisfies the general physicians' requirement for the accuracy of the measurement about 1-2 degrees.
