Description
Technical field
The present invention relates to belt conveyor technical fields, and in particular to a kind of rubber conveyer belt ponding automatic testing method.
Background technique
Belt conveyor is mechanical as a kind of continuative transport, and because it has, carrying capacity is strong, continuous operation is steady, convenient for certainly
The advantages that dynamic control, is widely used among the engineering fields such as coal mine, harbour, power plant's transport.Rubber conveyer belt is belt conveyor
The critical component of traction and carrying.When open-air atmosphere uses belt conveyor, the rainy day can form ponding on rubber conveyer belt.Such as
Fruit can cause very big influence without removing water process to the material on rubber conveyer belt.
Summary of the invention
The purpose of the present invention is to propose to a kind of rubber conveyer belt ponding automatic testing method based on machine vision, with automatic
The problem of detecting glue conveyer belt ponding.
The technical solution adopted to achieve the purpose of the present invention is as follows:
A kind of rubber conveyer belt ponding automatic testing method, comprising steps of
Read the image I of the rubber conveyer belt of camera acquisition；
Gray level image G is converted by the image I；
Area-of-interest is intercepted from the gray level image G；
Threshold value T is obtained by rubber conveyer belt rubber areas；
Binaryzation is carried out to rubber conveyer belt sunk area using the threshold value T, the image B after obtaining binaryzation；
White pixel point statistics is carried out to the image B after binaryzation, according to statistical result, exports judging result.
When the number of white pixel point is greater than N, it is judged as there is ponding, N is the image pixel of rubber conveyer belt sunk area
The 50% of point sum.
Area-of-interest is intercepted from gray level image G from described, is according to rubber conveyer belt actual condition, from grayscale image
It not will form outside rubber conveyer belt sunk area and rubber conveyer belt sunk area as intercepting ponding easy to form in G
The rubber conveyer belt rubber areas of ponding.
Described obtains threshold value T by rubber conveyer belt rubber areas, is the gray scale using rubber conveyer belt rubber areas
Threshold value T is arranged in the average value of value.
The present invention is based on machine vision techniques, and the image of rubber conveyer belt is acquired by the camera of fixed position, is utilized
The method of image procossing detects ponding situation automatically, solve the fields such as harbour, power plant, coal mine it is outdoor using rubber conveyer belt when
The automatic test problems of ponding.
Detailed description of the invention
Fig. 1 is the operational flowchart of rubber conveyer belt ponding automatic testing method of the present invention；
Fig. 2 is the image of camera collection in worksite；
Fig. 3 is the water detection result figure obtained using the method for the present invention.
Specific embodiment
The specific embodiment of summary of the invention is illustrated with reference to the accompanying drawing.
As shown in Fig. 1, rubber conveyer belt ponding automatic testing method proposed by the present invention, comprising the following steps:
Step 1, the live image I as shown in Figure 2 of camera acquisition is read；
Step 2, gray level image G is converted by image I；
Step 3, according to rubber conveyer belt actual condition, interested two regions are intercepted from gray level image G, respectively
The sunk area ROI of ponding easy to form-con(water accumulation part shown in Fig. 2, a rectangle of 100 depressed area of rubber conveyer belt
Region 10) and sunk area ROI-conOutside not will form the rubber areas ROI of ponding-rub(water accumulation part shown in Fig. 2 is left
Side forms a rectangular area 20 on slope on rubber conveyer belt)；
Step 4, pass through rubber areas ROI-rubThreshold value T is arranged in the average value of gray value；
Step 5, using T, to sunk area ROI-conCarry out binaryzation, the image B after obtaining binaryzation；
Step 6, to the image B after binaryzation, white pixel point statistics is carried out, (N is when the number of white pixel point is greater than N
Sunk area ROI-conThe 50% of image slices vegetarian refreshments sum), it is judged as there is ponding, is otherwise judged as no ponding.
To the result after Fig. 2 detection as shown in figure 3, white area is pools zone in Fig. 3.
Operation of the present invention is easy, algorithm is simple, and calculation amount is small, execution efficiency is high, speed is fast, and algorithm of the present invention can
To realize in embedded systems, such as realized by ARM, DSP, FPGA, it, can also be by upper to further increase arithmetic speed
Machine software realization.
The present invention is practical using the operating condition of rubber conveyer belt, and binarization threshold is arranged, ensure that the validity of correcting algorithm
And accuracy.
The method of the present invention is not limited to rubber conveyer belt ponding and detects automatically, applies also for other based on machine vision
Non-destructive testing in.
One embodiment of the present invention has been described in detail above, rather than limitation of the present invention, related technology are led
The technical staff in domain without departing from the spirit and scope of the present invention, can also make it is various transformation and variation so as to
To obtain corresponding equivalent technical solution, therefore all equivalent technical solutions should be included into patent protection of the invention
Range.
