DETAILED DESCRIPTION
[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0062] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0063] Reference Figures 1 to 6 The present invention discloses a bottled solution transporting device based on machine vision, comprising:
[0064] body;
[0065] A column 2 is arranged on the vehicle body in a liftable manner, and a clamping assembly for clamping the bottle body is installed on the column 2;
[0066] The clamping assembly includes a plurality of adaptive clamping parts 3, which can adaptively change according to the size of the bottle;
[0067] The adaptive clamping part 3 includes:
[0068] Mounting block 303, fixedly connected to column 2;
[0069] Two arc-shaped arms 301 are fixed to the front and rear sides of the mounting block 303 respectively;
[0070] The telescopic module is fixed to the arc-shaped arms 301 and is located between the two arc-shaped arms 301;
[0071] A mounting bracket is fixed to the movable end of the telescopic module;
[0072] A plurality of clamping members are arranged in sequence on the mounting bracket, and the clamping members and the mounting bracket are slidably arranged;
[0073] The locking mechanism is in transmission connection with the plurality of clamping members. The locking mechanism is used to fix the positions of the clamping members after the clamping members adaptively change according to the size of the bottle body.
[0074] During use, the vehicle body is moved to make the clamping assembly approach the bottle to be clamped. After the adaptive clamping part 3 is sleeved on the outside of the bottle, the mounting bracket is moved by the telescopic module so that the several clamping members on each mounting bracket are in contact with the outside of the bottle. After the clamping members are in contact with the outside of the bottle, as the mounting bracket continues to move, the clamping members slide on the mounting bracket until the several clamping members wrap the bottle. The position of each clamping member is fixed by the locking mechanism. The distribution of each clamping member matches the contour of the bottle. As the several clamping members are locked, the telescopic module continues to move the mounting bracket to generate a clamping force. Then the column 2 rises, and after the bottle is lifted, the vehicle body is moved to the designated position.
[0075] As an optional embodiment, the telescopic module includes a telescopic rod 302 , a fixed end of the telescopic rod 302 is fixedly connected to the arc-shaped arm 301 , and a movable end of the telescopic rod 302 is fixedly connected to the mounting bracket.
[0076] As an optional embodiment, the mounting bracket includes a first crossbar 304 fixed to the movable end of the telescopic rod 302 and a second crossbar 305 fixed to the first crossbar 304, with a gap being provided between the second crossbar 305 and the first crossbar 304;
[0077] The clamping member is slidably disposed within the second crossbar 305 .
[0078] As an optional embodiment, the clamping member includes:
[0079] The sliding housing 310 is slidably connected to the second crossbar 305, and a gap is provided between the sliding housings 310 of two adjacent clamping members;
[0080] A second spring 315 is coaxially sleeved outside the sliding housing 310 , one end of the second spring 315 is fixedly connected to the sliding housing 310 , and the other end of the second spring 315 is fixedly connected to the side wall of the second crossbar 305 ;
[0081] An inner sliding rod 311 is slidably disposed within the sliding housing 310. One end of the inner sliding rod 311 is fixedly connected to a sealing plate 316 and is located within the sliding housing 310. The sealing plate 316 and the inner wall of the sliding housing 310 form a piston chamber 317.
[0082] A first spring 314 is coaxially sleeved on the outer side of the inner slide rod 311 , one end of the first spring 314 is fixedly connected to the sealing plate 316 , and the other end of the first spring 314 is fixedly connected to the inner wall of the sliding housing 310 ;
[0083] The arc-shaped clamping groove 312 is fixed to the other end of the inner sliding rod 311 and is located outside the sliding housing 310;
[0084] The clamping rubber 313 is fixed to the end of the arc-shaped clamping groove 312 away from the inner sliding rod 311;
[0085] The inner sliding rod 311 and the sliding outer shell 310 are both transmission-connected to the locking mechanism.
[0086] When in use, the clamping rubber 313 contacts the bottle body. Since the surface of the bottle body is curved, the curved clamping groove 312 is set to an arc shape to better fit the contour of the bottle body. The clamping rubber 313 is elastic. On the one hand, it can change according to the contour of the bottle body, and on the other hand, it can increase the friction with the surface of the bottle body. After the clamping rubber 313 contacts the bottle body, as the second cross bar 305 continues to move, the sealing plate 316 first slides in the piston cavity 317 and stretches the first spring 314. At the same time, the sliding shell 310 can also slide relative to the second cross bar 305 to stretch the second spring 315. This arrangement can increase the moving stroke of the curved clamping groove 312 to adapt to bottles of more sizes. The gas in the piston cavity 317 is discharged. After all the curved clamping grooves 312 are moved into place, they can be locked by the locking mechanism.
[0087] After use, as the clamping force with the bottle surface decreases, the locking mechanism is unlocked, and the sliding housing 310 and the arc-shaped clamping groove 312 are reset by the first spring 314 and the second spring 315 .
[0088] As an optional embodiment, the locking mechanism includes a first locking structure and a second locking structure. The first locking structure is disposed in the second crossbar 305 and is used to fix the plurality of sliding housings 310.
[0089] The second locking structure is disposed on one side of the plurality of piston chambers 317 and is used to fix the plurality of inner sliding rods 311 .
[0090] As an optional implementation, the first locking structure includes:
[0091] An air chamber 306 is provided in the second crossbar 305 and is disposed between two adjacent sliding housings 310 ;
[0092] Two rubber membranes 307 are fixed to either side of the air chamber 306. One side of the rubber membrane 307 is in frictional contact with the corresponding sliding housing 310, and the other side of the rubber membrane 307 is disposed within the air chamber 306. When the air chamber 306 is inflated, the rubber membrane 307 is deformed and squeezes the corresponding side wall of the sliding housing 310.
[0093] A second air supply line 318 is provided in the second crossbar 305 and is in communication with the bottoms of the plurality of air chambers 306;
[0094] The second air supply assembly is connected to the middle portion of the second air supply pipeline 318 .
[0095] As an optional embodiment, the second air supply assembly includes:
[0096] The connecting block 319 is fixedly connected to the middle portion of the second cross bar 305 , and one end of the connecting block 319 is connected to the middle portion of the second air supply pipeline 318 ;
[0097] The second solenoid valve and the barometer 320 are connected to the other end of the connecting block 319. The second solenoid valve and the barometer 320 are connected to the air pump 7, which is fixed to the vehicle body.
[0098] As an optional implementation, the second locking structure includes:
[0099] One end of the first air supply pipeline 308 is connected to the plurality of piston chambers 317 , and the other end of the first air supply pipeline 308 is connected to the first solenoid valve and the barometer 309 , which are connected to the air pump 7 .
[0100] During use, initially, the first solenoid valve and barometer 309 and the second solenoid valve and barometer 320 are all in a connected state. At this time, the gas in the piston chamber 317 can be discharged through the first air supply pipeline 308. When locking is required, the air pump 7 simultaneously supplies air to the first air supply pipeline 308 and the second air supply pipeline 318, and the gas enters the piston chamber 317 and the air chamber 306.
[0101] The gas entering the piston chamber 317 pushes the sealing plate 316 to move the inner slide rod 311. The air pressure is balanced with the reaction force fed back by the bottle body, and the clamping force is increased by increasing the air pressure. After the first solenoid valve and the pressure gauge 309 are closed, the piston chamber 317 can maintain the specified air pressure.
[0102] The gas entering the air chamber 306 pushes the rubber membrane 307 to deform and squeeze the sidewall of the sliding housing 310. The frictional force secures the sliding housing 310 to the second crossbar 305. The second solenoid valve and barometer 320 are opened, allowing the air pump 7 to pump air into each air chamber 306 through the second air supply line 318. After the second solenoid valve and barometer 320 are closed, the air pressure in the air chamber 306 is maintained at the specified level.

[0111] The operation of the device can be programmed and controlled and powered by the controller and power supply 13. The device is equipped with a rear-view camera 4 and a front-view camera 8, and a visual recognition program is set in the controller to realize the functions of moving the device, grabbing the bottle, and releasing the bottle.
[0112] As an optional embodiment, the moving part includes:
[0113] Two drive wheels 9 are symmetrically arranged at the front end of the vehicle body 1 in the direction of travel. The drive wheels 9 are rotatably connected to the vehicle body 1.

[0115] The two driving wheels 9 are driven to rotate by the driving motors 10 respectively. By controlling the speed and direction of the driving motors 10 respectively, the functions of moving forward, backward, and turning of the vehicle body can be realized.

[0134] Furthermore, this device is equipped with a panoramic vision system based on the catadioptric principle, which is applied to the vehicle's autonomous navigation. With the catadioptric panoramic vision system as the core, the navigation path recognition algorithm and navigation control algorithm are researched and designed on the existing hardware platform.
[0135] The method comprises the following steps: first, analyzing the characteristics of various machine vision systems, and on this basis, summarizing the advantages of panoramic vision system over traditional machine vision system, and according to the advantages and disadvantages of various ways, selecting the panoramic vision system based on catadioptric principle as the navigation sensor of the robot, which is low in cost, fast in imaging speed, and very suitable for occasions with high real-time requirements; the panoramic vision system based on catadioptric principle uses a convex mirror with a certain surface shape to reflect the information of the environment around the robot into a camera for imaging, and obtains the environmental image in the horizontal 360° and a certain angle vertical field of view; due to the compression of the convex mirror to the scene environmental information, there is a radial distortion of the object in the imaging plane of the camera, so that some regular objects in the actual scene are deformed in imaging; according to the imaging characteristics of the panoramic vision system based on catadioptric principle, the commonly used several calibration methods of panoramic vision system are compared, and the distance and angle of the scene image in a certain actual plane parallel to the plane of the camera are calibrated through the experimental method, and the corresponding relationship between the object image points is obtained; this method does not need to know the internal and external parameters of the camera and the parameter equation of the mirror surface, has lower requirements for the installation of the system, and is convenient for calibration; second, designing the crop row environment image acquisition and processing algorithm of the panoramic vision system based on catadioptric principle, a. using Directshow technology to collect the camera image; according to the characteristics of the working environment, the collected image is preprocessed, the color correction of the collected color image is carried out by using the gray world assumption algorithm and the white balance algorithm and the diagonal correction model, and the essential color of the object is approximately restored; b. on this basis, the image is grayed by using the normalized green feature value 2xg-r-b, and then the binary image of the working environment is obtained by using the maximum inter-class variance method; c. the pulse noise points in the image are removed by using the median filter, and the ideal binary image of the surrounding environment is obtained; d.According to the characteristics of panoramic system imaging, the calibration results are used to transform the distance and angle of the target pixels to restore the spatial straight line characteristics, which is convenient for extracting the navigation path line; the third step is to use Hough transform to identify the navigation reference path, and calculate the navigation control parameters in combination with the digital compass heading angle information; on the basis of image acquisition and processing, combined with the characteristics of catadioptric panoramic vision system imaging, the direction information of the navigation reference path line is obtained by using Hough transform, and the straight line closest to the center point and the closest distance to the imaging center is selected as the navigation reference path line; combined with the initial angle information of the digital compass, the navigation control parameters are calculated; the fourth step is to design a navigation controller based on the fuzzy control method and conduct experimental verification; analyze the navigation control methods commonly used in navigation, and compare and study various methods. Based on the characteristics of the operating environment, fuzzy control is used as the navigation control method in this design because it does not require a precise mathematical model of the controlled object and is similar to human thinking. The design process of the fuzzy controller is analyzed in detail, and a two-dimensional fuzzy controller based on two-wheel differential control is designed. The input is the navigation control parameters, and the output is the rotational speed of the left and right wheels of the vehicle. The design and experimental verification are carried out using MATLAB. The results show that the fuzzy controller can accurately track the navigation path line. The fifth step is to conduct a simulated navigation control test in an indoor environment without fixed light source illumination. The overall device is debugged and navigation control tests are conducted indoors in an environment without fixed light source illumination. The results show that the system can accurately identify the navigation path line and stably track the identified navigation path line.
