Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a defect labeling method according to an embodiment of the present invention.
As shown in fig. 1, the defect labeling method according to the embodiment of the present invention may include the following steps:
and S1, acquiring the product image, and acquiring the defect type and the defect coordinate in the product image.
Specifically, a product image needing to be marked with a defect is obtained, and the type of the defect is obtained, wherein the defect comprises: air bubbles, scratches, black spots, etc. And establishing a coordinate system according to the size of the product image, for example, establishing the coordinate system by using the upper left corner of the product image as a coordinate origin. The coordinates of the position where the defect sits are obtained, for example, when the type of the defect is a scratch, the coordinates of the start point to the end point of the scratch are obtained, and the coordinates of the scratch in the middle of the start point to the end point can also be obtained.
And S2, acquiring the defect area according to the defect type and the defect coordinate.
According to one embodiment of the present invention, acquiring a defect region according to a defect type and defect coordinates includes: determining a marking mode according to the defect type; acquiring a marking element according to the marking mode and the defect coordinate; and connecting the marking elements to obtain the defect area.
In an embodiment of the present invention, the labeling method includes: closed region mark and broken line mark, wherein, closed region mark includes: one or more of rectangular, circular, and polygonal.
Specifically, a marking mode is determined according to the defect type, for example, when the defect type is a bubble, a closed area marking mode is adopted for marking the defect, and when the defect type is a scratch, a broken line marking mode is adopted for marking the defect. After the labeling manner is determined, the labeling elements are obtained according to the coordinates of the defect, for example, as shown in fig. 2 and fig. 3, all the labeling elements are connected to obtain a defect area, where fig. 2 shows a closed area labeling manner, a dotted line part in the drawing shows a defect area, and fig. 3 shows a broken line labeling manner.
The determination mode of the labeling element is as follows: and acquiring the coordinate with the maximum transverse coordinate and the maximum longitudinal coordinate in the defect coordinates, and acquiring the coordinate with the minimum transverse coordinate and the minimum longitudinal coordinate in the defect coordinates, so that the type of the defect can be roughly determined, and the defect coordinates are used as marking elements to draw a defect area.
Of course, a plurality of defect coordinates, not limited to the maximum coordinate and the minimum coordinate, may be obtained to more accurately determine the defect type. For example, when the defect type is a bubble, the bubble is approximately circular, and at this time, the farthest distance in the defect coordinates is obtained as a diameter, and a circle drawn by taking the center of the diameter as a dot is taken as a defect area.
And S3, when the defect coordinate is not completely in the defect area, modifying the defect area to make the defect completely in the defect area.
According to one embodiment of the present invention, modifying the defect area to make the defect completely within the defect area when the defect coordinates are not completely within the defect area includes: acquiring a defect coordinate which is not in a defect area; and moving the marking element of the defect area corresponding to the defect coordinate, and driving the line segment connected with the marking element to move so as to enlarge the defect area.
Further, according to an embodiment of the present invention, when the defect coordinates are completely within the defect area, the defect area is labeled as a defect and stored.
Specifically, whether the defect coordinate is completely located in the defect area is determined, for example, whether the defect coordinate is located in the defect area may be determined by comparing the sizes of the defect coordinates, and when the defect coordinate is not located in the defect area, the corresponding label element of the defect area is moved, it is noted that the label element corresponding to the defect coordinate is a label element on a line segment corresponding to the defect coordinate, for example, point a in fig. 4 is a label element corresponding to the defect coordinate of point B, and an arrow indicates the moving direction of the defect area, so that the defect is completely located in the defect area, the defect labeling is completed, and the defect label is stored.
According to one embodiment of the invention, when the number of defect coordinates which are not in the defect area is larger than a preset number threshold, the defect area is deleted, and the defect area is obtained again. The preset quantity threshold value can be calibrated according to actual conditions.
That is, when most of the defect is not within the defect area, the current defect area is deleted and the defect area is redrawn according to the defect type and the defect coordinates.
In conclusion, the defect labeling method of the invention acquires the product image and acquires the defect type and the defect coordinate in the product image; acquiring a defect area according to the defect type and the defect coordinate; when the defect coordinates are not completely within the defect region, the defect region is modified so that the defect is completely within the defect region. The defect marking method can meet different marking requirements of product defects, increases marking diversity, increases drawing fault tolerance rate and reduces marking time by changing the defect area.
