Three-dimensional measuring method and three-dimensional measuring apparatus

摘要

After calibration for three-dimensional measurement has been completed, specification of a range of height to be measured is accepted, and using a homography matrix corresponding to the specified range on each of the images A0 and A1 from respective cameras, a range is extracted where a point included in the viewing fields of both of the cameras appears among points in the specified height range. Further, the extracted range is color-displayed as a measurable range on each of the images A0 and A1.
