Abstract
The invention discloses an on-line detection method for cables on the basis of machine vision. The method comprises the steps as follow: image information and position information of the cables are collected; alarm information is obtained through template matching, mode recognition, defect scratch detection and positioning; the alarm information and the cable positions are combined, and the like. The on-line detection method for the cables has the advantages of high execution speed and accuracy, stable performance and the like.
Description
Technical field
The present invention relates to a kind of detection method, be specifically related to a kind of cable online test method based on machine vision.
Background technology
The making of cable comprises a plurality of continuous operations, the method of finished product detection cannot be found bad in processing procedure in time, and scope bad when finding defective products is very large, and online detection mostly is manual detection at present, workload is huge, and the criterion of sight check exists larger fluctuation.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of cable online test method based on machine vision.
Technical scheme: for solving the problems of the technologies described above, the cable online test method based on machine vision provided by the invention, comprises the following steps:
1) polygon mirror coordinates light source and linear video camera to gather the image information of four faces of cable simultaneously;
2) the length metering equipment records cable positional information of cable;
3) image information gathering is carried out to stencil matching, pattern-recognition, defect scratch detection location, obtain warning message;
4) warning message and cable position are combined, for next process, defective cable is processed.
As preferably, for the timely real-time adjusting process parameter of alert, when obtaining warning message in described step 3), send sound and light alarm.
Beneficial effect: the present invention utilizes machine vision and length metering equipment, there is execution speed fast, the advantage such as accuracy is high and stable, and can detect the defect that on cable, human eye cannot detect, online detection can be found in time bad and prevent it to expand, ensure the yield of finished product.
Embodiment
Embodiment: the cable online test method based on machine vision of the present embodiment, comprises the following steps:
1) polygon mirror coordinates light source and linear video camera to gather the image information of four faces of cable simultaneously.
2) the length metering equipment records cable positional information of cable.
3) image information gathering is carried out to stencil matching, pattern-recognition, defect scratch detection location, obtain warning message, send sound and light alarm, the real-time adjusting process parameter of alert simultaneously.
4) warning message and cable position are combined, for next process, defective cable is processed.
Wherein polygon mirror is existing prism apparatus, can the information of four faces of wire rod be pooled to a video camera by reflection, has simplified the layout of video camera and the treatment capacity of data.
Utilize detection method of the present invention can effectively control surface defects of products, reduce business economic loss.And the equipment automatically detecting alleviated reviewer's labour intensity, personnel and post have been simplified.The method of judging by Computer Image Processing also can correctly be assessed product surface quality, reduces user quality objection.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to claim scope.
Claims (2)
