A method for calibrating a part of the same image - velocimeter and part of the same image - velocimeter

摘要

The invention relates to a method for calibrating a part of the same image - velocimeter (10), in particular of a stereo - part of the same image - velocimeter, the at least one camera (60) and a passage (12) for a fluid, comprises, comprising the steps of: intersecting of a first laser beam (20) with a second laser beam (22) in an overlapping within the passage (12), detecting at least a position of the zone of a beam - position of the laser beams (20, 22), receiving a first image and of at least one second image by means of the zone of the camera (60) and calibration of the part of the same image - velocimeter on the basis of the at least one of the position detected and the at least one image.
