Abstract :
This paper describes the system to measure height of human by triangulation using stereo vision which installs two cameras on the ceiling in a stably lighted room. However, there were difficult cases of extraction by the conventional technique. So, we proposed the human extraction method using optical flow, in addition to conventional technique. As an experimental result, the human´s head could be extracted in all images, and the average error was 2.5[cm]
