Improvement of precision by introducing vitality degree to the height measurement system using stereo vision

This paper describes the system to measure height of persons by using the stereo vision which installed two cameras in an indoor ceiling. In this paper, we propose introduction of the vitality degree in this system for the purpose of improvement of measurement precision. As experimental result by the proposed system, high precision about the height measurement was provided. That is, the average error was 1.05[cm] and the maximum error was 2.82[cm]. In addition, this system satisfies real time processing in simple configuration consisting of one general-purpose personal computer and a stereo camera.
