Embodiment
The utility model is described in detail with case study on implementation below in conjunction with the accompanying drawings.
Use motor coupler（7-4）Two tested motors are linked up, are placed on conveyer belt（6）On.
Ultrasonic transmitter（1）Detection sound wave is constantly sent, works as conveyer belt（6）On testee enter default scope
It is interior, ultrasonic wave module by testee " it was found that " signal feeds back to breast board controller via data wire（3-1）, then by breast board control
Device processed（3-1）Breast board will be controlled（3-2）Stretch out.
Breast board controller（3-1）Sending signal makes fence device（3）Power supply（3-7）It is powered, in coil（3-6）Effect
Under, surrounding produces magnetic field, and mutually exclusive according to magnetic pole of the same name, magnetic force will repel bar magnet downwards by spring（3-5）, then
Draw scalable intelligent breast board（3-2）Extend downwardly from, play the iris action to target object.
In fence device（3）Lower end fixed in position pressure sensor（3-3）, when testee arrival predeterminated position, and
Press sensor（3-3）When, sensor will be sent to electrical axis picture recognition module by signal by data wire " in place "
（2）, electrical axis picture recognition module（2）Control laser shot-light（2-2）Launch laser beam.Now testee reaches default
Test position, camera（2-1）The center of face motor coupler, the laser shot-light of the right and left auxiliary positioning（2-2）Face
And the rotating shaft of a little higher than motor（7-3）, light projection can be formed location spot on black baffle plate (5)（8-1）.Electrical axis
Picture recognition module（2）With location spot（8-1）For the center of circle, motor shaft is established as radius using the distance slightly larger than motor shaft length
Region to be identified（8-2）.
Subsequent electrical axis picture recognition module（2）Pass through camera（2-1）Picture is gathered, go forward side by side row threshold division and spy
Determine the extraction of region contour pixel.Following steps will be executed for program：Using fixed threshold dividing method to two electricity to be detected
The original image of machine shaft coupling enters row threshold division, obtains binary map.Then neighborhood Contour extraction is carried out to the binary map, specifically
Way is whether the gray scale for checking eight adjacent pixels of current pixel belongs to a certain specified range（The model being previously set
Enclose）, the scope is to distinguish profile point and non-profile point, by the binary map of Threshold segmentation principle formation only edge contour.
Then, the binary map in the range of the motor shaft fringe region is preserved, and detects whether electrical axis align：(1) with row
The average value of electrical axis pixel point coordinates in image is calculated for unit, generation identifies the straight line of electrical axis horizontality, and
The slope of straight line is calculated, if slope is equal, or error then enters step (2) in allowed band, otherwise illustrates electrical axis not
Alignment；(2) average value of all phase vegetarian refreshments position coordinateses on same root motor shaft is calculated again, if calculating electrical axis pixel seat
Mark average value is equal or error is in allowed band, then it is assumed that electrical axis align, and meet the requirements.
When judged result is not line up, electrical axis picture recognition module（2）Output control signal, make spray gun power supply
