Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of localization method for silk-screen halftone that the embodiment of the present invention 1 provides includes step：
S110, the halftone is shot from capture point, obtains the halftone image.
Control shoots the halftone positioned at the photographic device of the capture point, obtains the capture of the photographic device
In the range of the halftone image.
Optionally, the photographic device can be industrial CCD video camera, and be realized by way of CCD captures to described
The shooting of halftone；In other cases, the photographic device can also be cmos camera or other video cameras, and pass through phase
The capture mode answered shoots the halftone, does not influence the advantageous effect that the present invention obtains.
S120, the image information that preset anchor point is extracted from the halftone image.
The image information of the anchor point is extracted from the halftone image, determines the image of the anchor point in the net
The location of in domain picture, the anchor point is located at the fixed position on the halftone.
As an example, image recognition processing can be carried out to the halftone image, identifies the institute in the halftone image
The image information of anchor point is stated, and records location information of the image of the anchor point in the halftone image.It is appreciated that
Ground in other cases, can also meet the image-region of preset condition by directly filtering out full figure in the halftone image
As the region where the image of the anchor point, the advantageous effect that the present invention obtains is not influenced.
S130, according to the image information of the anchor point and the position of the capture point, determine the present bit of the halftone
It puts.
Position of the anchor point relative to the capture point is determined by the image information of the anchor point got,
Since the anchor point is located at the fixed position on the halftone, it may further determine that the halftone is filled relative to the capture
The position put, and since the image-taking device for obtaining the halftone image is fixed on the capture point, there is fixed capture
Region may further determine that the current location of the halftone.
S140, the position deviation for calculating the current location and preset operating position, and the halftone is adjusted to institute
State preset operating position.
According to the current location of the halftone got in step S130, with the operating position of preset halftone into
Row compares, and calculates the position deviation between the current location and the operating position, based on the position deviation, by described in
Halftone is adjusted on the operating position.
As an example, the position deviation can be between the coordinate of the current location and the coordinate of the operating position
Difference, motion vector is gone out according to the mathematic interpolation, and the halftone is adjusted to the working position according to the motion vector
It puts.It is to be appreciated that in other cases, can also determine specific path curve, such as camber line or broken line, this hair is not influenced
The advantageous effect of bright acquirement.
