Embodiment
Referring to Fig. 1, the utility model provides a kind of double laser beam plane positioning system based on image interpretation, and this system comprises first turntable 2, second turntable 3, reflecting prism 4 and IMAQ and processing unit; Reflecting prism 4 places between first turntable 2 and second turntable 3; IMAQ and processing unit are arranged on the light path after reflecting prism 4 reflections; IMAQ and processing unit comprise the graphics processing unit 6 that image acquisition units 5 and image acquisition units 5 connects, and image acquisition units 5 can be that for example the equipment that can catch image such as video camera or CCD all is fine.Graphics processing unit 6 can be the computing machine that contains image mending, comparison and/or interpretation function.
Should also comprise turntable angle display unit 1 based on the double laser beam plane positioning system of image interpretation; Turntable angle display unit 1 links to each other with second turntable 3 with first turntable 2 respectively.
The principle of work of the utility model in laser doppler velocimeter system is:
The utility model is when work; Twin-laser 7 is separately fixed on first turntable 2 and second turntable 3, and light beam carries out imaging system, the computer acquisition light beam image after reflecting through reflecting prism 4; Image interpretation software is handled two light beam images, obtains two angle of beams relations.When two light beams were parallel after reflecting prism 4 reflections, two positions of light beam in image overlapped fully, at this moment, thought that two laser instrument 7 emitted light beams are that conllinear is aimed at.Revolving table position with this moment is with reference to zero degree, rotates double axle table, can obtain arbitrarily two laser beam angles.The angle of light beam is to obtain through the turntable angle calculation.
