[0040] Embodiment 1

[0041] As Figures 1-5 shown, an automatic vehicle photo dispensing system provided in this embodiment includes:

[0042] A handling module 3, and the handling module 3 is used to handle vehicles;

[0043] A positioning module 1, the positioning module 1 is arranged on one side of the grasping module 6, and the positioning module 1 is used to position the parking position of the handling module 3;

[0044] Vehicle information input module 4, which is used to read the vehicle information of the vehicle parked in the positioning module 1;

[0045] Photographing module 2, which is arranged on one side or above the positioning module 1 and is used to take pictures of the vehicle parked in the positioning module 1;

[0046] Printing module 5, which is connected to the photographing module 2 and is used to print the pictures taken by the photographing module 2;

[0047] Inspection module, which is used to inspect the pictures printed by the printing module 5;

[0048] Grabbing module 6, which is used to grab the pictures that pass the inspection into the vehicle;

[0049] Control module, which is used to connect the handling module 3, the positioning module 1, the vehicle information input module 4, the photographing module 2, the printing module 5, the inspection module and the grabbing module 6.

[0050] Specifically, the handling module 3 can adopt an existing AGV conveying trolley. The AGV conveying trolley is controlled by the control module to transport the vehicle to the corresponding position along a fixed walking route. The AGV conveying trolley realizes automatic driving through a laser navigation, magnetic stripe navigation or gyroscope guiding system, without manual operation, and can complete the handling task of goods according to the preset path. In addition, the AGV conveying trolley also has an automatic charging function and will automatically return to the charging station for charging when the power is insufficient.

[0051] The positioning module 1 includes a positioning platform 11 and optoelectronic sensors 7. The positioning platform 11 is arranged on one side of the grabbing module 6. The number of optoelectronic sensors 7 is two groups. Detection lines 12 and parking lines 13 are provided on the positioning platform 11, and the detection lines 12 and the parking lines 13 are distributed at intervals on the positioning platform 11. The two groups of optoelectronic sensors 7 respectively correspond to the detection lines 12 and the parking lines 13. Specifically, the optoelectronic sensor 7 is a sensor based on the photoelectric effect and can convert the optical signal into an electrical signal. Its working principle is that the optical signal emitted by the light source irradiates the object to be detected. According to the different characteristics of the object to the light, the optical signal changes, and finally the optical detector receives and converts it into an electrical signal. The positioning platform 11 is fixed to the ground. The detection line 12 cooperates with a group of optoelectronic sensors 7 to detect that the AGV conveying trolley moves to the positioning platform 11. This group of optoelectronic sensors 7 sends a signal to the control module, and the control module controls the AGV conveying trolley to decelerate and stop, so that the AGV conveying trolley stops moving in front of the parking line 13 to prevent the vehicle information input module 4, the photographing module 2 and the grabbing module 6 from not working properly.

[0052] The vehicle information entry module 4 is set on one side of the positioning platform 11. The vehicle information entry module 4 includes a barcode scanner. The barcode scanner 43 is set on one side of the positioning platform 11, and the scanning end of the barcode scanner 43 faces the positioning platform 11. The barcode scanner 43 is used to scan the vehicle VIN code. Scanning the vehicle VIN code by the barcode scanner 43 is a technology that uses optical character recognition (OCR) technology to quickly read the vehicle identification number (VIN code) by means of a camera. The VIN code is the unique identity identifier of the vehicle, containing key information such as the vehicle manufacturer, production year, and vehicle model. By scanning the VIN code, detailed vehicle information such as the place of origin, brand, model, model year, displacement, and number of seats can be quickly obtained, thereby improving work efficiency and accuracy. Specifically, the VIN code recognition technology is usually based on OCR technology. The VIN code image is captured by a mobile phone camera, and the vehicle information is automatically parsed using image processing algorithms. This method not only improves the speed of data entry but also reduces errors that may occur during manual input. For example, the traditional manual entry method takes about 30 seconds to enter a 17-digit VIN code, while using the barcode scanner 43, the recognition can be completed in less than 1 second.

[0053] Considering the different positions of the vehicle VIN code, corresponding horizontal adjustment structures 41 and height adjustment structures 42 are set, such as existing lead screw assemblies. The horizontal adjustment structure 41 and the height adjustment structure 42 are formed by the cooperation of two groups of lead screw assemblies. Among them, the two groups of lead screw assemblies are respectively arranged vertically and horizontally. The horizontally arranged lead screw assembly is fixed on the slider of the vertically arranged lead screw assembly, and the barcode scanner 43 is fixed on the slider of the horizontally arranged lead screw assembly. The barcode scanner 43 is driven to move in the horizontal and vertical directions by driving the corresponding lead screw to rotate, and the driving motor is controlled by the control module.

[0054] The photographing module 2 includes a first photographing component 22 and a second photographing component 21. The first photographing component 22 is disposed on one side of the positioning module 1, and the second photographing component 21 is disposed above the positioning module 1. The first photographing component 22 and the second photographing component 21 are respectively used for taking a stereoscopic photograph and an overhead photograph of the vehicle, and both the first photographing component 22 and the second photographing component 21 are connected to the printing module 5. Specifically, the first photographing component 22 and the second photographing component 21 have the same structure. The first photographing component 22 includes a first gantry 221 and two first cameras 222. The first gantry 221 is fixed in front of the vehicle, and the two first cameras 222 are respectively fixed on the left and right sides of the top end of the first gantry 221, and both the two first cameras 222 are disposed facing the vehicle direction. The second photographing component 21 includes a second gantry 211 and two second cameras 212. The two columns of the second gantry 211 are respectively fixed on both sides of the middle of the positioning platform 11, the cross beam of the second gantry 211 is located above the middle of the positioning platform 11, and the two second cameras 212 are fixed on the cross beam of the second gantry 211, and the two second cameras 212 are disposed facing the top of the vehicle.

[0055] The printing module 5 includes a printer, and the printer is respectively connected to the vehicle information input module 4 and the photographing module 2. The printer receives the photograph and the vehicle information and prints the corresponding photograph and the vehicle information. The printer is an existing printer and will not be elaborated here.

[0056] The inspection module includes a visual image analysis module, and the visual image analysis module inspects the photograph. Specifically, images of the vehicle are obtained through the first camera 222 and the second camera 212, and then the images are preprocessed by the control module, including operations such as smoothing filtering and image enhancement, to improve the quality and clarity of the images. The shape features of the vehicle are extracted, and one or more classifier models are established according to known standards and rules. These models will be trained according to the known product image data set to learn how to distinguish qualified products from unqualified products and how to identify various defects. The trained models and algorithms are used to detect and identify new product images. The system will automatically analyze the images, search for vehicle information that conforms to the preset rules, and perform classification and determination. According to the recognition result, the vehicle information and the photograph of the corresponding photographed vehicle are printed out, grabbed by the grabbing module 6 to the transfer table 8, and the visual image analysis module analyzes whether there are inconsistencies, printing quality problems, passing vehicle verification, photograph integrity, ink shortage and discoloration of the photograph, etc. through machine vision. If there is no problem, the grabbing module 6 grabs the photograph and puts it into the vehicle. The algorithms and models mentioned here are all existing algorithms and models, such as the intelligent vision detection technology of Yingtaide Technology (Shenzhen) Co., Ltd., the review of saliency object detection methods based on deep learning, and the algorithms and models recorded in the principle of machine vision detection technology - machine vision detection solution - machine vision detection system.

[0057] The grasping module 6 includes a grasping manipulator, which includes a base, a first rotating arm 61, a second rotating arm 62, a third rotating arm 63, a fourth rotating arm 64, and a vacuum chuck 65. The base is fixed between the positioning module 1 and the printing module 5. The first rotating arm 61 is connected to the base through a first rotating motor. The second rotating arm 62 is connected to the first rotating arm 61 through a second rotating motor. The third rotating arm 63 is connected to the second rotating arm 62 through a third rotating motor. The fourth rotating arm 64 is connected to the third rotating arm 63 through a fourth rotating motor. The vacuum chuck 65 is connected to the fourth rotating arm 64. Specifically, the grasping manipulator realizes multi-angle movement through the first rotating arm 61, the second rotating arm 62, the third rotating arm 63, and the fourth rotating arm 64, so that it can adsorb the photo from the printer to the transfer cabinet and then adsorb and place it into the vehicle from the transfer cabinet. The number of vacuum chucks 65 is four or five. If the number is four, they are distributed in a rectangle. If the number is five, four are distributed in a rectangle and the remaining one is located in the middle of the four. Through such a setting, firm adsorption of the photo is achieved.

[0058] A transfer table 8 is provided between the grasping module 6 and the printing module 5. The top plane of the transfer table 8 is provided with a negative pressure chuck, and the inspection module is installed on the top of the transfer table 8.

[0059] An automatic vehicle photo placement system in this embodiment uses the handling module 3 to move the vehicle to the positioning platform 11. The positioning module 1 detects the in-place information of the vehicle. After receiving the in-place information sent by the positioning module 1, the control module controls the vehicle information entry module 4 to read the vehicle information of the vehicle's VIN code (if the vehicle has no VIN code, the vehicle information entry module 4 does not work and directly extracts the vehicle information corresponding to the vehicle from the vehicle information pre-stored in the control module). At the same time, it controls the photographing module 2 to take a photo of the vehicle, uses the machine vision system to process and identify the photo, obtains the correspondence between the vehicle appearance and the corresponding vehicle information, prints the photo and the vehicle information onto the photo through the printing module 5, grabs the photo to the transfer table 8 through the grasping module 6, and the inspection module uses the machine vision system to inspect to avoid putting photos with inconsistencies or printing quality problems. After the photo is qualified, it grabs the photo into the vehicle through the grasping module 6; the above entire process can be automated without manual intervention, improving the photo placement efficiency, ensuring the photo inspection is in place, and preventing vehicle photos from being missed and placed into the vehicle.
