The vision measurement device of the ship geometry of contact, device is surveyed using 4 industrial cameras to hull geometry size
Amount, with specificity;The Chinese patent of Application No. 201310698709.9 proposes a kind of regarding for plate shaping limit curve
Feel measurement apparatus, device carries out taking map analysis using vision camera to deformable material, curved edge degree is calculated, so as to draw material
Expect forming limit curve, method is easy to use;The Chinese patent of Application No. 201410275227.7 propose it is a kind of complete into
As vision measurement device, the device equally uses the desk-top measuring method of loading, complete the axiality of axial workpiece, circular runout,
The measurement of cylindricity etc.;The Chinese patent of Application No. 201510395713.7 proposes a kind of face of cylinder based on 3D vision
Radius measurement method, method obtains the three dimensional point cloud on the face of cylinder by dimensional visual measurement system, then spreads out into
Two dimensional surface data, are then based on the sort algorithm of angle by two-dimensional development into one-dimensional point sequence, are carried out according to one-dimensional point sequence
Ellipse fitting and circle are fitted, so as to obtain radius, this method anti-noise ability is strong, precision is higher.Foregoing invention employs vision
E measurement technology is used as measuring method, although complete the measurement to target, but can not realize on-line real-time measuremen and statistical
Analysis, it is impossible to feedback is monitored to process capability, it is impossible to adapt to produce in enormous quantities.
Therefore the online total detection in real time of needle-valve part and monitoring are realized, as enterprise's urgent need to solve the problem.Carry on the back herein
Under scape, the present invention is based on machine vision metrology technology, realizes efficient to needle-valve, high-precision non-contact measurement and sorting,
Can statistical measurement data in time, for the timely feedback of lathe, and the assembling of later stage fuel injector and security have it is important
Meaning.
