Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
The invention provides a belt detection method, as shown in fig. 4, the belt detection method comprises the following steps: receiving an image of the belt 10 to be detected, which is acquired by an image acquisition device; identifying an image of a belt end 11 location of the belt 10 from the received image; acquiring a characteristic value of the belt joint 11 part from the image of the belt joint 11 part; and comparing the characteristic value with a pre-stored standard value, and judging whether the position of the belt joint 11 is abnormal or not according to a comparison result.
The structure of the belt joint 11 of the belt 10 is shown in fig. 2, the belt joint 11 is a connection position of belt buckles of the front and rear belt sections, and a mandrel 12 is arranged between the two belt buckles in a penetrating manner, so that the two belt sections are connected.
As can be seen from fig. 2, the width of each belt segment is reduced at the belt buckle portion, so that the side of the belt segment is inclined at an angle, and thus the side of the belt end 11 portion forms a triangular opening, which is shown as angle a in fig. 2.
The belt detection method of the invention acquires and analyzes the image of the belt 10, and judges whether the image is the image of the belt joint 11 part or not by identifying the shape of the edge of the belt joint 11 part of the belt 10, namely the shape of the edge of the triangle, thereby realizing the identification of the belt joint 11 part.
In one embodiment, the features used for identification include a triangular opening at the edge of belt 10, and the angle a of the included angle of the edge of belt 10. When any edge of the belt 10 is recognized to have a triangular opening with an angle a, the pattern is recognized as an image of the belt joint 11.
In the running process of the belt 10, the belt joint 11 may be cracked due to excessive tension, so that the included angle of one side is changed, and therefore, the above embodiment can avoid misjudgment caused by the above situation.
In another embodiment, the features used for identification include a triangular opening at the edges of both sides of belt 10, and the angle a of the included angle of the edges of belt 10. Only when the triangular opening with the angle a appears at both side edges of the belt 10, the pattern is recognized as an image of the belt joint 11.
In the operation process of the belt 10, the part of the belt 10 other than the belt end 11 may be cracked due to the excessive tension, and at this time, the edge of the position where the belt is cracked may generate a triangular opening, so that the above embodiment can avoid the misjudgment caused by the above situation.
In another preferred embodiment, the features used for identification include a triangular opening in the edges of both sides of belt 10, and the angle a of the included angle of either side edge of belt 10. That is, when a triangular opening is recognized at both side edges of the belt 10 and the opening angle at either side is a, the image is recognized as an image of the belt end 11.
After the image of the belt joint 11 is recognized, the characteristic value of the belt joint 11 portion is obtained from the image of the belt joint 11 portion.
First, the center line of the belt 10 and the two side edges of the belt end 11 are determined from the image of the belt end 11, and then the distances from the two side edges of the belt end 11 to the center line of the belt 10 are determined.
As shown in fig. 3, the feature values include: the distance t from one side edge of the belt 10 at the belt end 11 to the centerline of the belt 10, and the distance p from the other side edge of the belt 10 at the belt end 11 to the centerline of the belt 10.
Comparing the characteristic value with a pre-stored standard value comprises: comparing a distance t from one side edge of the belt joint 11 of the belt 10 to the center line of the belt 10 with a pre-stored standard value d to obtain a first difference value; and comparing the distance p from the other side edge of the belt joint 11 of the belt 10 to the center line of the belt 10 with a pre-stored standard value d to obtain a second difference value.
As shown in fig. 5, the absolute value of the difference between the distance t from one side edge of the belt end 11 to the center line of the belt 10 and the standard value d is calculated, and the difference between the distance p from the other side edge to the center line of the belt 10 and the standard value d is calculated. If any difference exceeds the threshold value, the belt joint 11 is determined to be abnormal.
If the absolute value of the difference between the distance t from one side edge of the belt joint 11 to the center line of the belt 10 and the standard value d is greater than the threshold value, or the absolute value of the difference between the distance p from the other side edge to the center line of the belt 10 and the standard value d is greater than the threshold value, it is determined that an abnormality occurs in the belt joint 11.
If the absolute value of the difference between the distance t from one side edge of the belt joint 11 to the center line of the belt 10 and the standard value d is less than or equal to the threshold, or the absolute value of the difference between the distance p from the other side edge to the center line of the belt 10 and the standard value d is less than or equal to the threshold, it represents that the difference is within a reasonable error range or the belt 10 is within a reasonable deformation range, it is determined that the belt joint 11 is not abnormal, and the belt detection method continues to repeatedly acquire new images.
Wherein the identification features and the pre-stored standard values are obtained by the following method: before the belt 10 starts to work, acquiring an image of a belt joint 11 part of the belt 10 as an initial image; the identification features and standard values of the belt 10 are obtained from the standard images and recorded.
Wherein, the shape and the angle a of the edge of the belt 10 are recorded and used as the identification characteristics of the image for identifying the belt joint 11; the distance d from the edge of the belt 10 at the belt end 11 to the center line of the belt 10 is obtained and recorded as a standard value stored in advance.
The specific method for obtaining the standard value comprises the following steps: obtaining the distance d from one side edge of the belt joint 11 to the center line of the belt 101And obtaining the beltDistance d from the other side edge of the joint 11 portion to the center line of the belt 102Get d1And d2The average value of (d) is defined as a standard value d.
