TECHNICAL FIELD
[0001] The present application relates to the technical field of shared bicycle parking management, and in particular to a shared bicycle parking management method. BACKGROUND
[0002] Shared vehicles such as shared bicycles and shared power-assisted bicycles, as a product of the sharing economy, bring great convenience to people's travel. However, shared transportation tools not only cause interference to road traffic, but also affect the city appearance while facilitating people's travel.
[0003] In order to solve the problem of random parking, the common means at present is to set a dedicated parking pile or a landmark with an electronic tag on the road, and the shared bicycle cooperates with the parking pile or detects and identifies the landmark, so as to realize orderly parking. However, setting the parking pile or the landmark not only has high construction cost, but also causes certain damage to the municipal road and occupies public space. SUMMARY
[0004] The purpose of the present application is to provide a shared bicycle parking management method capable of managing users to return the bicycle in an orderly manner without occupying or damaging the existing road surface.
[0005] To solve the above problems, the present application provides a shared bicycle parking management method applied to a shared bicycle and a server, wherein the shared bicycle is provided with an information manager for communication to the server, a trigger for detecting whether a foot support is opened, and a camera for shooting the ground, and the foot support is located within the shooting range of the camera.
[0006] The method comprises a user use stage, if the trigger detects that the foot support is in an opened state, the camera shoots to obtain a feature image and transmits the feature image to the information manager, and the information manager temporarily stores the feature image after converting the feature image into a gray image.
[0007] If the user issues a return instruction, the information manager transmits the gray image to the server, the server compares the foot support pattern in the gray image with a standard pattern in terms of similarity, if the similarity does not meet the requirement, the user is prompted that the foot support is not opened in place, if the similarity meets the requirement, the server searches for straight line patterns around the foot support pattern, selects a plurality of straight line patterns for angle measurement, and determines whether to allow the user's return request according to whether the angle measurement result meets the requirement.
[0008] Compared with the prior art, the above scheme firstly detects the state of the foot prop through the trigger, so that the camera only shoots the feature image when the foot prop is unfolded; and then the information manager converts the feature image into a gray image, which not only makes the shape pattern in the feature image more obvious, but also helps to reduce the data volume. After the user issues a return command, the server first compares the foot prop pattern with the standard image in terms of similarity, and confirms that the gray image meets the requirements; considering that the parking area of the shared bicycle is usually a sidewalk paved with tiles, the straight line pattern around the foot prop pattern is searched and selected, and the straight line pattern represents the tile joint; if the angle measurement of the straight line pattern meets the requirements, it means that the shared bicycle is in an aligned state relative to the tile joint, and the user is allowed to return the bicycle at this time; if the angle measurement of the straight line pattern does not meet the requirements, it means that the shared bicycle is in an inclined state relative to the tile joint, and the user is not allowed to return the bicycle at this time or is reminded to move the bicycle, so that the bicycle can be returned in an orderly and tidy manner without occupying or damaging the existing road surface.
[0009] As a preferred, when the server searches the straight line pattern around the foot prop pattern, if parallel straight line patterns are searched, the parallel straight line patterns are selected for angle measurement, and the parallel straight line patterns have a higher probability of being tile joints, so they can be more accurately used as reference patterns for angle measurement.
[0010] As a preferred, when the server searches the straight line pattern around the foot prop pattern, if no parallel straight line patterns are searched, the longest straight line pattern among all the searched straight line patterns is selected for angle measurement, and the longer the straight line pattern, the higher the probability of being a tile joint, so it can be more accurately used as a reference pattern for angle measurement.
[0011] As a preferred, when the server searches the straight line pattern around the foot prop pattern, if no straight line pattern is searched, the user is required to take a feedback image with a mobile phone, and the feedback image is transmitted to the server before the user is allowed to return the bicycle, so that it is suitable for some scenarios where there are no tiles or the tiles are too large to capture the tile joints.
[0012] As a preferred, the trigger is a proximity switch arranged at the lower part of the shared bicycle, and the detection end of the proximity switch is opposite to the foot prop, and the foot prop is made of metal, so that the state of the foot prop can be accurately detected.
[0013] As a preferred, the camera is arranged adjacent to the foot prop on the shared bicycle, and the camera is covered by the foot prop when the foot prop is retracted, so that the camera is protected during the driving of the shared bicycle. BRIEF DESCRIPTION OF DRAWINGS

[0019] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present application will be described clearly and completely below by combining the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. In addition, it should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.
[0020] Please refer to Figs. 1-3 The embodiments of the present application provide a shared bicycle parking management method, which is applied to a shared bicycle 2 and a server 1. The shared bicycle 2 is provided with an information manager 21 for communication to the server 1, a trigger 22 for detecting whether a kickstand 24 is opened, and a camera 23 for shooting the ground. The kickstand 24 is located within the shooting range of the camera 23.
[0021] The method comprises a user use stage. If the trigger 22 detects that the kickstand 24 is in an opened state, the camera 23 shoots to obtain a feature image and transmits the feature image to the information manager 21. The information manager 21 temporarily stores the feature image after converting the feature image into a gray image.
[0022] If the user issues a return command, the information manager 21 transmits the grayscale image to the server 1, the server 1 compares the foot support 24 pattern in the grayscale image with the standard pattern, if the similarity does not meet the requirements, it prompts the user that the foot support 24 is not opened to the position, if the similarity meets the requirements, the server 1 searches the straight line pattern around the foot support 24 pattern, and selects several straight line patterns for angle measurement, and decides whether to allow the user's return request according to whether the angle measurement result meets the requirements.
[0023] The above scheme first detects the state of the foot support 24 through the trigger 22, which ensures that the camera 23 only shoots the feature image when the foot support 24 is opened; then the information manager 21 converts the feature image into a grayscale image, which not only makes the shape pattern in the feature image more obvious, but also helps to reduce the data volume. After the user issues a return command, the server 1 first compares the foot support 24 pattern with the standard image for similarity, and confirms that the grayscale image meets the requirements; considering that the parking area of the shared bicycle 2 is mostly a sidewalk paved by tiles, therefore, by searching and selecting the straight line pattern around the foot support 24 pattern, the straight line pattern represents the tile joint, if the angle measurement of the straight line pattern meets the requirements, it means that the shared bicycle 2 is in the aligned state relative to the tile joint, at this time the user is allowed to return the bicycle; if the angle measurement of the straight line pattern does not meet the requirements, it means that the shared bicycle 2 is in the inclined state relative to the tile joint, at this time the user is not allowed to return the bicycle or is prompted to move the bicycle, thereby realizing orderly return without occupying or damaging the existing road surface.
[0024] More specifically, the trigger 22 and the camera 23 are both electrically connected to the information manager 21 through wires, and the information manager 21 is a micro circuit board provided with a communication module. In the user's non-use stage, the trigger 22 and the camera 23 are both in the disabled state; while in the user's use stage, the information manager 21 controls the trigger 22 to be in the enabled state.
[0025] The user can issue a return command through a mobile phone, or a return button can be provided on the shared bicycle 2, and the user presses the return button to issue a return command; after the information manager 21 transmits the grayscale image to the server 1, the server 1 compares the foot support 24 pattern in the grayscale image with the standard pattern for similarity, if the similarity is less than 80%, the similarity does not meet the requirements, prompting the user that the foot support 24 is not opened to the position; if the similarity is greater than or equal to 80%, the similarity meets the requirements, and the server 1 starts searching the straight line pattern around the foot support 24 pattern. The above-mentioned standard pattern refers to the foot support 24 pattern in the grayscale image when the foot support 24 is completely opened.
[0026] In the server 1 searches the straight line pattern around the foot support 24 pattern, at least one straight line pattern is selected for angle measurement, and the length of the straight line pattern is more than 1 / 2 of the height of the foot support 24. If the angle between the selected straight line pattern and the horizontal line is within ±20°, or the angle between the selected straight line pattern and the vertical line is within ±20°, it is determined that the shared bicycle 2 is aligned with the tile joint, and the user is allowed to return the bicycle. If the angle between the selected straight line pattern and the horizontal line is outside ±20°, or the angle between the selected straight line pattern and the vertical line is outside ±20°, it is determined that the shared bicycle 2 is misaligned with the tile joint, and the user is not allowed to return the bicycle and is reminded to adjust the angle of the shared bicycle 2.
[0027] In the present embodiment, when the server 1 searches for a straight line pattern around the foot support 24 pattern, if a parallel straight line pattern is found, the parallel straight line pattern is directly selected for angle measurement. The probability of the parallel straight line pattern being a tile joint is higher, so it can be more accurately used as a reference pattern for angle measurement. Further, when the server 1 searches for a straight line pattern around the foot support 24 pattern, if no parallel straight line pattern is found, the longest straight line pattern among all the searched straight line patterns is selected for angle measurement. The longer the straight line pattern, the higher the probability of being a tile joint, so it can be more accurately used as a reference pattern for angle measurement.
[0028] As an improvement to the above embodiment, when the server 1 searches for a straight line pattern around the foot support 24 pattern, if no straight line pattern is found, the user is required to take a feedback image with a mobile phone, and the feedback image is transmitted to the server 1 before allowing the user to return the bicycle, so that it is suitable for some scenarios where there are no tiles or the tiles are too large to capture the tile joint.
[0029] In the present embodiment, the trigger 22 is a proximity switch arranged at the lower part of the shared bicycle 2, and the proximity switch is located at the front side of the foot support 24. The detection end of the proximity switch is arranged opposite to the upper part of the foot support 24. The foot support 24 is made of metal material, so that when the foot support 24 is turned towards the ground and expanded, the proximity switch will be triggered by detecting the approach of the foot support 24, and send a corresponding signal to the information manager 21. The information manager 21 controls the camera 23 to collect the feature image.
[0030] In the present embodiment, the camera 23 is installed at the lower part of the shared bicycle 2 and located behind the foot support 24. When the foot support 24 is retracted, it covers the camera 23, thereby protecting the camera 23 during the driving of the shared bicycle 2.
[0031] Although the present disclosure discloses as above, the protection scope of the present disclosure is not limited to this. Various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and these changes and modifications shall fall within the protection scope of the present disclosure.
