Whether match and can be specifically defined as with the end face of the axial workpiece 40 in benchmark image：Axial workpiece in first image
40 end face size matches with datum end face size, and the endface position and reference edge of the axial workpiece 40 in the first image
Face position matches, and the end surface shape of the axial workpiece 40 in the first image matches with datum end face shape.It needs to refer to
Go out, it is so-called in above three condition to match, can be equal or the error range in permission in it is equal.
For example, datum end face shape is circle, datum end face size is that (the end face radius i.e. in benchmark image is 100 pixels
100 pixels), the end face of benchmark carrying groove 30a the lowermosts axial workpiece 40 is corresponding in image on the basis of datum end face position
Central coordinate of circle, then it is circle, and the first image that above three condition, which can be the end surface shape of the axial workpiece 40 in the first image,
In the end face size of axial workpiece 40 be 100 pixels, and 30 the lowermost axial workpiece 40 of carrying groove in the first image
The corresponding circle in end face of benchmark carrying groove 30a the lowermosts axial workpiece 40 in the corresponding central coordinate of circle in end face and benchmark image
Heart coordinate is numerically identical.Certainly, if the bottom of carrying groove 30 is not placed with axial workpiece 40, first can also be taken
The axial workpiece 40 of corresponding position carries out position versus in the axial workpiece 40 and benchmark image of other positions in image.It needs
It points out, although only compared 30 the lowermost axial workpiece 40 of carrying groove in third condition and benchmark carrying groove 30a is most lower
The axial workpiece 40 at end, but due to the relative position relation between each axial workpiece 40 in carrying groove 30 be it is fixed, because
This only compares an axial workpiece 40 and is sufficient in theory, can also be chosen from carrying groove 30 in practice certainly more
The axial workpiece 40 of corresponding position carries out position versus in a axial workpiece 40 and benchmark carrying groove 30a.
Under the above-mentioned definition mode to match, if the end face of axial workpiece 40 in the first image and benchmark image
In the end face of axial workpiece 40 match, what is characterized is exactly end face and the reference map of the axial workpiece 40 in the first image

The radius of axial workpiece 40 be significantly less than the radius of the axial workpiece 40 in the benchmark carrying groove 30a in benchmark image, control
Device 100 can calculate the radius of the circle in the first image, and calculate the difference of itself and the radius of the circle in benchmark image, according to
The difference controls third motor drive operational platform 118 and translates, until the difference was 0 (allowing certain error) in the second image.Always
It, in moving process continuous repeating above said collection image, judge whether matching, control the second motor 112 driving workbench
The process of 118 movements determines the carrying groove 30 that imaging sensor 102 acquires until when carrying groove 30 is moved to first position
The second image in axial workpiece 40 end face and benchmark image in the end face of axial workpiece 40 match, so that it is determined that
Carrying groove 30 has moved to predeterminated position, and first position is predeterminated position.In practice, above-mentioned three kinds of positions adjustment side
Formula can carry out in a certain order, such as first carry out workbench 118 and rotate, and adjust end surface shape, then carry out workbench
118 translations, adjust separately endface position and end face size.
The method that above-mentioned control workbench 118 translates be only limitted in the first image include axial workpiece 40 end face
Axis class may also be not present in fact since carrying groove 30 can arbitrarily be placed on workbench 118 in situation in first image
The case where end face of axial workpiece 40 in the end face of part 40, such as carrying groove 30 is back to imaging sensor 102, or remove
Fortune slot 30 is located at the case where part in 102 visual field of imaging sensor does not include the end face of axial workpiece 40, at this time above-mentioned side
