摘要: The present invention relates to a method and device for measurement of diameter cylindrical objects (2) with longitudinal axis from distance. A according the invention, comprises following steps: generating an illuminated line intersection (10) substantially object by light source (6), being perpendicular axis, capturing image this means camera (12), optical (15) which is oriented towards inclined respect (10), having two extremities corresponding (2), calculating based on image, calculation supposition that projections are tangents (2). elements.
