In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
As shown in fig. 1, a mechanism for obtaining a diameter of a casing by visual recognition includes:
an industrial camera 2 provided with a depth-of-field lens, which shoots a sausage casing 3 irradiated by light;
the control processor (not shown) processes the image captured by the industrial camera 2 to obtain the diameter size of the casing 3.
In the prior art, an array CCD industrial camera and an upper computer are used for measuring the diameter of the sausage casing, the array CCD is used for non-contact measurement, the array CCD is placed in a light path, a measured object is placed in the light path in front of the CCD, and light emitted to the CCD is partially blocked by an object, so that a signal output by the CCD has a notch, obviously, the width of the notch and the size of the object have a one-to-one correspondence relationship, and the upper computer processes the notch to obtain the number of CCD pixels corresponding to the notch, thereby calculating the diameter (width) of the measured sausage casing. However, such a caliper has the following problems: (1) in the measuring method, the cost of the CCD is expensive, and the application of the sausage casing diameter measuring equipment is limited to a certain extent; moreover, the CCD light sensitive area has certain size limitation, which directly limits the size of the measured sausage casing, thereby limiting the measurement of the diameter of the sausage casing. (2) In this measurement method, only the diameter of the flat casing is measured, and the flat casing needs to be closely attached to the flat plate during measurement, but the measurement method has a large error in the measurement of the diameter of the casing in the suspended state and the inflated state, and is not suitable for measuring the diameter of the casing in the suspended state and the inflated state. (3) When measuring the diameter of a flat casing, if there is residual air inside the flat casing, the measurement may also be inaccurate.
The industrial camera 2 photographs the casing 3 irradiated with light, and the casing can be irradiated with light by a light source built in the industrial camera or by a light source 1 provided separately. The light source provides light irradiation for the casing, so that the view of the industrial camera 2 provided with the depth-of-field lens is clearer, the influence of the light darkness of the ambient light is avoided, and the definition of a shot image is ensured.
In the technical scheme, the industrial camera 2 provided with the depth-of-field lens is adopted, so that the diameters of casings 3 to be measured in different states, such as flat casings, casings in an inflated state or casings in a suspended state, and the like, can be measured, and the diameters of casings 3 to be measured in different sizes (the size of the casings 3 to be measured is limited by the view finding width of the depth-of-field lens) can be measured, so that the application range is wide, and the measurement precision is high.
As a preferable scheme, the depth of field lens in the industrial camera 2 is a large depth of field lens, and the industrial camera 2 provided with the large depth of field lens is used for taking a high-frequency picture of the aerated casing passing through at high speed in real time, wherein the large depth of field lens is a telecentric lens with the depth of field of 25mm or more.
In the technical scheme, the industrial camera 2 provided with the depth-of-field lens shoots the casing 3, and the depth-of-field lens collects parallel images of the casing 3; the size of the image shot by the lens with the large depth of field is the same no matter the distance of the shot target is far and near, so the technical scheme has no limitation on the shooting time and can realize real-time shooting.
Specifically, by adopting the industrial camera 2 equipped with a lens with a large depth of field, the diameter of the casing 3 conveyed at the fastest conveying speed in the current industrial production can be measured. In the technical scheme, in order to improve the measurement efficiency, the casing 3 passing at a high speed is shot at a high frequency, the passing speed of the casing 3 depends on the highest shooting frequency (namely, frame rate) of the industrial camera 2, and the higher the shooting frequency of the industrial camera 2 is, the higher the allowable casing passing speed is.
At present, the high-frequency industrial camera 2 captures a motion track of a high-speed moving object at a high-frequency shooting speed, can capture pictures which cannot be captured by naked eyes, and is an important tool for an industrial production line. The basic parameters of the high-frequency industrial camera 2 are related to the model of the machine, the signals are different, and the basic parameters are also different, such as the imported i-speed 3 of olympus, the resolution of which is 1280 x 1024 at 2000 frames/second, and the maximum frame rate is 150000 frames/second; and for example, the home-made Qianyou wolf 2F-16 with the highest resolution of 16M (4600 multiplied by 3440) supports the shooting speed of 65000 frames/second in small picture. By adopting the industrial camera 2 with a proper frame rate, the passing speed of the casing 3 can be effectively improved, and the detection efficiency of the diameter of the casing 3 is improved.
The frame rate of the cameras is related to pixels, and generally, the higher the resolution is, the lower the frame rate is, and the frame rates of industrial cameras of different brands are slightly different; the required resolution of the industrial camera can be calculated according to the size of the casing 3, the resolution to be achieved and the performance of the used software, and different industrial cameras are selected according to the temperature, humidity, interference condition and lighting condition which need to be considered in the field environment. Therefore, the industrial camera 2 with an appropriate frame rate may be selected according to actual shooting requirements.
In the technical scheme, the processing process of the image by the control processor is basically the same as the processing process of the image by the diameter measuring instrument for measuring the diameter of the casing by using the CCD industrial camera in the prior art, and the technical scheme does not improve the processing of the image by the control processor.
The mechanism for acquiring the diameter of the casing by utilizing visual identification can be applied to various occasions needing measuring the diameter of the casing, and has wide application range. For example, diameter measurements can be made on the casing 3 during the casing production process; the diameter of the sausage casing 3 can also be measured after production and before shrinkage; the method can be applied to single equipment for measuring the size of the casing; the device can also be applied to equipment for humidifying or spraying oil on the inner part and the outer part of the sausage casing, and the diameter change of the sausage casing after the humidifying or spraying oil is detected; and so on.

In this embodiment, the rotating speeds of the first winding wheel 42 and the second winding wheel 43 are controlled to enable the sausage casing 3 between the extrusion head 41 and the winding device to pass through quickly, so that the measuring speed of the diameter of the sausage casing 3 is increased, and the sausage casing production equipment can be adjusted in real time according to the measured diameter of the sausage casing 3 to ensure that the produced sausage casing 3 meets the requirements.

As shown in fig. 3, in order to measure the diameter of the casing 3 after production and before casing shrinkage, the casing 3 is unwound from the casing drum 54 to the casing shrinkage device 51 under the driving of the unwinding device, the casing 3 between the unwinding device and the casing shrinkage device 51 is inflated to form a cylinder, and the suspended inflated casing 3 between the unwinding device and the casing shrinkage device 51 is measured by the mechanism for obtaining the diameter of the casing through visual recognition.
