The traditional sorting method uses manual sorting, which results in low sorting efficiency and is prone to errors and waste. Cauliflowers of different varieties and specifications have different sorting requirements. Although the existing cauliflower sorting system has introduced a semi-automatic auxiliary screening device, it cannot optimize sorting according to user needs to meet specific sorting requirements and lacks traceability.

The driven wheel is set at the feeding end, and the cauliflower enters the feeding end in turn at a certain distance. A detection box is set at a distance from the driven wheel. In order to achieve a higher sorting accuracy, a row of cauliflowers can be set on the conveyor belt. If the camera collects an image every 1s for processing, the speed of the seed conveyor belt can be adjusted by adjusting the speed of the three-phase asynchronous motor through the inverter of the motor drive device, so as to ensure that the camera will not lose the cauliflower image after each image acquisition, and avoid missed inspection.

The driven wheel is set at the feeding end, and the cauliflower enters the feeding end in turn at a certain distance. A detection box 2 is set at a distance from the driven wheel.

The industrial camera is connected to the system controller through a data line.

[0030] The light source is an important component of the machine vision recognition part. A suitable light source will affect the quality of the collected image and thus affect the processing accuracy and efficiency of the entire system. The LED lighting and industrial camera are installed on the top of the detection box 2. The LED lighting is a ring light source. The ring light source is set to the lens of the industrial camera CCD to ensure that the light source is vertically irradiated. The lens of the industrial camera is facing the cauliflower on the conveyor belt. During automatic control, the camera automatically takes a picture every 1s, which can also be adjusted according to actual needs.

[0031] The sorting management terminal 1 includes a user interaction module, an image recognition module, a data storage module and a system controller. The user interaction module is used to obtain user identity authentication information, and obtain the cauliflower sorting size parameters, color parameters, compactness parameters and weight parameters input by the user, and visually display the operation status information and abnormal warning information of the current intelligent sorting line. The user interaction module includes a liquid crystal display, a server, an input keyboard and a fingerprint recording device.

The server and the system controller are connected through a connecting line, and relevant data logic processing can be realized. The user can input the corresponding parameter information through the input keyboard. The fingerprint recording device is used to record the user's fingerprint identity information, which is convenient for subsequent identity information verification.

[0032] The image recognition module is connected to the user interaction module. The image recognition module includes an image preprocessing module and a pest and disease recognition module. The image preprocessing module is used to filter, reduce noise and enhance the collected image, and transmit the obtained feature data to the pest and disease recognition module. The pest and disease recognition module is used to extract features and classify and identify cauliflower pests and diseases using a machine learning algorithm. The data storage module includes a sorting database, which is used to store detection and sorting data. The system controller is electrically connected to the user interaction module, the image recognition module and the data storage module. The system controller is used to verify the user's identity according to the verification information input by the user, and send a control signal to the sorting device according to the image recognition result and the size judgment result, and control the sorting device to classify and sort the cauliflower. The pest and disease information sorted can also be used to count the pest rate of cauliflower, which is convenient for subsequent planting optimization. The pest and disease identification module includes a feature extraction module and a classification identification module. The feature extraction module is used to convert the collected RGB image into the HSV color space, and the pixels in the HSV image are clustered into multiple color approximate regions using the K-means algorithm. Based on the results of the K-means clustering, the saliency map is calculated. The classification identification module is used to identify and classify pests and diseases based on the saliency image features using the convolutional neural network model. Specifically, based on the results of the K-means clustering, the color contrast between each pixel and the surrounding pixels is calculated according to the distance in the HSV color space, the calculated contrast value is normalized to the range of 0-1 to obtain the saliency value, the saliency value is used as the new pixel value to obtain the saliency map, and the saliency image features are input into the convolutional neural network model for identification.

[0033] Image preprocessing requires filtering and noise reduction, and the filtering adopts an adaptive filtering algorithm. After preprocessing the image data, its target features need to be extracted and then classified and identified. The convolutional neural network model adopts the VGG model.

[0034] In this embodiment, the image recognition module also includes a feature classification module, which is connected to the preprocessing module. The feature classification module is used to perform target segmentation on the preprocessed image, obtain the size information and hole information of the currently detected cauliflower according to the segmentation result, and compare the size information and hole information with the size threshold parameters and the number and area threshold of the holes uploaded by the user, and classify and sort the cauliflower according to the comparison result. The size information and hole information refer to the outer contour circumference of the cauliflower and the number of closed holes and the pixel area of ​​the holes, respectively. For example, if the outer contour circumference is greater than the preset threshold N and the number of closed holes and the pixel area of ​​the holes are less than the preset threshold M, the cauliflower is judged to be qualified in terms of compactness (greater than the preset threshold).

[0035] When performing target segmentation on the preprocessed image, the threshold processing technology is used to convert the image into a binary image, and then the morphological operation and region growing algorithm are used to connect the hole target area of ​​the cauliflower as the initial area. The GrabCut algorithm is used for iterative segmentation, and the size and number of the segmented image area are used to judge the compactness of the cauliflower.

[0036] like Figure 2 As shown, the sorting device includes multiple groups of primary sorting ports and multiple groups of secondary sorting ports, each of which is provided with a first sorting baffle 3, each of which is provided with a second sorting baffle 4 and a falling material collection bucket, and the front end of the primary sorting port and the front end of the secondary sorting port are both provided with a beam-type photoelectric switch, and the sorting baffle is controlled by a baffle driving mechanism, and the beam-type photoelectric switch and the baffle driving mechanism are both electrically connected to the system controller. Among them, the baffle driving mechanism includes a rotating shaft 5, a gear 6, a tooth plate 7 and a cylinder, the rotating shaft 5 is fixedly connected to the sorting baffle, the end of the rotating shaft 5 is fixedly connected to a gear 6, the gear 6 is meshed with the tooth plate 7, one end of the tooth plate 7 is fixedly connected to the piston rod of the cylinder, and the control end of the cylinder is electrically connected to the system controller. The cylinder drives the piston rod to move, driving the tooth plate 7 to move forward and backward, thereby driving the gear 6 meshed with the tooth plate 7 to rotate, and the rotation of the gear 6 drives the rotating shaft 5 to rotate, thereby causing the sorting baffle to rotate a certain angle.

[0037] A sorting baffle is installed at each sorting port. The sorting baffle can be controlled by the cylinder to rotate a certain angle, and then the cauliflower is picked. The cylinder is provided with a pressure regulating valve, which can adjust the force and speed of the sorting baffle opening and closing. When the sorting baffle is opened, it will block and pick the cauliflower on the conveyor belt. When it is closed, the cauliflower will be directly sent to the secondary sorting port or the falling material collection bucket. And when the sorting baffle is closed, it is flush with the baffle plate to avoid affecting other cauliflowers on the conveyor belt. When the cauliflower passes through the photoelectric switch or weight sensor in turn, the photoelectric switch or weight sensor will capture the passing signal and weight signal of the cauliflower and send it to the system controller. The system controller records and calculates the weight and position information of the cauliflower to determine which sorting port each cauliflower should be sent to. When the cauliflower is transported to the sorting port, the sorting baffle will open in advance to accept the cauliflower, and drive the sorting baffle to close the sorting port after entering the sorting port. In this way, accurate grading of product quality and weight can be achieved quickly.

[0038] The sorting device also includes a sorting mechanical arm 8, on which a teaching pendant is provided, and the bottom end of the sorting mechanical arm 8 is fixedly mounted on a rotating drive platform, and the rotating drive platform adjusts the rotation angle according to the control signal sent by the teaching pendant, and the rotating drive platform includes a turntable, on which a first rotating arm is provided, and the end of the first rotating arm is connected to the front end of the second rotating arm through a rotating joint, and a pneumatic clamp is fixedly installed at the end of the second rotating arm, and the turntable and the rotating joint are built with a driving motor for driving the turntable to rotate horizontally and the rotating joint to rotate longitudinally, so that cauliflower with pests and diseases can be grasped according to different needs. The collected image is processed to screen out unqualified cauliflower with pests and diseases, and then the teaching pendant receives the control signal of the system controller, and then controls the servo motor to send a pulse signal, controls the movement of the mechanical arm, and the grasping end of the mechanical arm reaches the position of the unqualified cauliflower to realize the operation of removing it.

[0039] The sorting robot arm 8 is arranged upstream of the sorting port, and each secondary sorting port is pre-set with a weight range for receiving cauliflowers. The cauliflowers entering the range will be sorted into the material collection bucket by the corresponding sorting baffle. The number of sorting ports determines the number of cauliflower grades. In this embodiment, three secondary sorting ports are arranged. When the cauliflowers are sorted, the disease and insect pest information of the cauliflowers is first obtained through the image recognition module, and the disease and insect pest cauliflowers are removed by the sorting robot arm 8. For the remaining cauliflowers, the primary sorting port performs initial sorting according to the compactness parameter and color parameter of the cauliflowers recognized by the image recognition module. In this embodiment, there are two primary sorting ports. When the compactness and color are both greater than the preset threshold, they are sorted into the primary sorting port A, when the compactness is greater than the preset threshold and the color is less than the preset threshold, they are sorted into the primary sorting port B, when the compactness is less than the preset threshold and the color is greater than the preset threshold or when the compactness and color are both less than the preset threshold, they are sorted into the secondary sorting port arranged at the end for weight screening.
