[0002] A mobile power supply device can be used to rent multiple mobile power supplies to provide terminal charging services to users. Specifically, users can rent a mobile power supply from a mobile power supply device by scanning a code or other methods; after use, they can return the rented mobile power supply by pressing the return button on the mobile power supply device and putting the mobile power supply back into the mobile power supply device. However, the current return method of mobile power supply devices has certain problems, resulting in a poor user experience. For example, there are cases where the user has already put the mobile power supply into the mobile power supply device, but the timer is still deducting the fee. Specifically, it may be due to system errors, the power bank is plugged in the wrong way or not plugged in tightly, the user needs to click twice to confirm the termination of charging but actually does not click twice, etc., which causes the user to think that the return is successful, but in fact it is not successful, and the background does not stop billing, resulting in a poor user experience.

The preset area is an area near the multiple power bank placement slots of the target power bank device. This allows for image capture during the process of returning the newly added power bank. Furthermore, upon identifying that at least one of the multiple images to be identified contains a preset biometric feature, target biometric information corresponding to the target subject is extracted based on the at least one image to be identified. This allows for biometric capture of the target subject during the process of returning the newly added power bank. Subsequently, the target biometric information is matched with rental biometric information corresponding to multiple rental subjects to obtain the target subject corresponding to the target biometric information. This allows for matching the biometric features of the target subject to determine the rental subject corresponding to the newly added power bank. Finally, a return instruction for the target subject is sent to a target server, causing the target server to update the target interaction status corresponding to the target subject to a stopped billing state. This avoids the situation where a power bank has been placed but backend billing is still ongoing. This effectively assists in determining the return of the power bank, thereby improving the user experience.

[0078] S201: When the target object places a new mobile power supply into any vacant power supply placement port of the target mobile power supply device, an image of a preset area is captured to obtain a plurality of images to be recognized.

[0079] In a specific embodiment, the target object may refer to an object that currently needs to return a power bank. The target object may be any one of multiple rental objects. The any rental object may refer to an object that rents any of the at least one rental power bank. The at least one rental power bank may refer to a preset power bank among multiple preset power banks that has been rented and not returned. The multiple preset power banks may refer to power banks provided for rent by multiple preset power bank devices.

[0080] In a specific embodiment, the newly added mobile power supply may refer to the mobile power supply currently returned by the target object. The newly added mobile power supply may be any one of the at least one rented mobile power supply.

[0081] In a specific embodiment, the target mobile power device may be a preset mobile power device into which the newly added mobile power device is placed. The target mobile power device may be a preset mobile power device corresponding to the target object among multiple preset mobile power devices corresponding to the power rental system. Specifically, the power rental system may include multiple rental terminals and a preset mobile power device corresponding to each rental terminal; the target terminal may be the rental terminal corresponding to the target object; and the target mobile power device may be a preset mobile power device corresponding to the target terminal.

[0082] In a specific embodiment, the target mobile power supply device may include multiple mobile power supply slots and at least one mobile power supply to be rented. Any mobile power supply slot may be used to place a preset mobile power supply. The at least one mobile power supply to be rented may be the preset mobile power supply placed in the mobile power supply slot. Any vacant power supply slot may be any slot among the multiple mobile power supply slots that does not contain a preset mobile power supply.

[0083] In a specific embodiment, the preset area may refer to an area near the multiple mobile power supply placement ports of the target mobile power supply device. Specifically, the preset area may be an area near the multiple mobile power supply placement ports of the target mobile power supply device and outside the multiple mobile power supply placement ports. Exemplarily, the image acquisition module of the target terminal may be set in front of the multiple mobile power supply placement ports of the target mobile power supply device, and the image acquisition module may be set upward so that the image acquisition area of the image acquisition module may be the preset area; or the image acquisition module may include multiple image acquisition units, each of which may capture the image of the area in front of the corresponding mobile power supply placement port; or alternatively, the image acquisition module may include multiple image acquisition units, and the multiple image acquisition units may capture images corresponding to the preset area from multiple different angles.

[0084] In a specific embodiment, the multiple images to be identified may refer to images of multiple preset areas collected during the process of inserting a new mobile power supply.

[0085] In a specific embodiment, upon recognizing that a target subject has inserted a new power bank into any vacant power port of a target power bank device, the target terminal may capture an image of a preset area to obtain multiple images to be recognized. Specifically, the target terminal may include an image capture module; upon recognizing that a target subject has inserted a new power bank into any vacant power port of a target power bank device, the image capture module in the target terminal may capture an image of the preset area.

[0086] In a specific embodiment, the target terminal may activate an image acquisition module to capture images to be identified upon detecting the presence of a preset mobile power supply in a preset area. Specifically, upon detecting the presence of an object in the preset area, the image acquisition module may be activated to capture an image of the preset area, thereby obtaining an image of the preset area; power supply identification processing may be performed on the image of the preset area to obtain a first identification result; and upon the first identification result indicating the presence of a preset mobile power supply in the image of the preset area, the image acquisition module may be activated to capture the multiple images to be identified.

[0087] In a specific embodiment, the target terminal may input a preset area image into a preset power source recognition model to perform power source recognition processing and obtain a first recognition result. Specifically, the preset power source recognition model may be obtained by training a preset machine learning model based on a sample image dataset corresponding to multiple preset mobile power sources.

[0088] S203: When it is identified that at least one of the multiple images to be identified has a preset biometric feature, target biometric feature information corresponding to the target object is extracted based on the at least one image to be identified.

[0089] In a specific embodiment, the preset biometric feature can be set according to actual application needs. Optionally, the preset biometric feature can include a palm print feature.

[0090] In a specific embodiment, the at least one image to be identified may refer to an image having a preset biometric feature among the multiple images to be identified.

[0091] In a specific embodiment, the target biometric characteristic information may represent the biometric characteristics of the target object. Specifically, the target biometric characteristic information may include palm print characteristic information of the target object.

[0092] In a specific embodiment, palmprint recognition can be performed on the multiple images to be identified to obtain a second recognition result. If the second recognition result indicates that at least one of the multiple images to be identified contains a preset biometric feature, a first target extraction image can be selected from the at least one image to be identified. Accordingly, feature extraction processing can be performed on the first target extraction image based on the feature extraction dimension corresponding to the preset biometric feature to obtain the target biometric feature information. Specifically, the first target extraction image can be selected from the at least one image to be identified based on preset image selection conditions. Exemplarily, the preset image selection conditions may include the corresponding image brightness being greater than the preset brightness, or the corresponding palmprint area ratio being greater than the preset area ratio, etc. Furthermore, when the second recognition result indicates that at least one of the multiple images to be recognized contains a preset biometric feature, a first target extraction image can be selected from the at least one image to be recognized; the first target extraction image can be segmented, and the image area corresponding to the preset biometric feature in the first target extraction image can be segmented from the first target extraction image to obtain a second target extraction image; and feature extraction processing can be performed on the second target extraction image from the feature extraction dimension corresponding to the preset biometric feature to obtain the target biometric information.

[0093] S205: Matching the target biometric information with the rental biometric information corresponding to the plurality of rental objects to obtain the target object corresponding to the target biometric information.

[0094] In a specific embodiment, the rental biometric information corresponding to any rental object may represent the biometric characteristics of any rental object. Specifically, the rental biometric information corresponding to any rental object may include palm print feature information corresponding to any rental object.

[0095] In a specific embodiment, during the process of any rental object renting a preset mobile power supply, a third preset prompt page can be displayed to prompt the rental object to collect biometric information; in response to the biometric collection instruction for any rental object, a feature collection image corresponding to any rental object can be obtained; the feature collection image is subjected to feature extraction processing to obtain the rental biometric information corresponding to any rental object. Accordingly, the rental biometric information corresponding to any rental object and the object identification information corresponding to the rental biometric information and any rental object can be stored. Furthermore, the rental biometric information corresponding to any rental object can be encrypted to obtain encrypted rental biometric information; accordingly, the encrypted rental biometric information can be stored in a local storage or uploaded to the cloud to improve system security.

[0096] In a specific embodiment, a request may be made to a target server to obtain rental biometric information corresponding to multiple rental objects; the target biometric information and the rental biometric information corresponding to the multiple rental objects are matched to obtain object identification information of the target object corresponding to the target biometric information.

[0097] In a specific embodiment, the plurality of rental objects may include at least one target rental object. The at least one target rental object may be a rental object from the plurality of rental objects that rents at least one target rental mobile power supply. The at least one target rental mobile power supply may be a preset mobile power supply rented from a target mobile power supply device from the at least one rental mobile power supply.

[0098] In a specific embodiment, the above step S205 may include:

[0099] Perform matching processing on the target biometric feature information and the target rental feature information to obtain a target matching result;

[0100] When the target matching result indicates that the target rental feature information includes rental biometric feature information that matches the target biometric feature information, the target rental object corresponding to the target matching result is used as the target object.

[0101] In a specific embodiment, the target rental feature information may refer to the rental biometric feature information corresponding to at least one target rental object among the rental biometric feature information corresponding to multiple rental objects. The target rental feature information may be stored in a local memory corresponding to the target terminal.

[0102] In a specific embodiment, the target matching result may be used to indicate whether there is rental biometric characteristic information in the target rental characteristic information that matches the target biometric characteristic information.

[0103] In a specific embodiment, the target terminal may obtain the target rental feature information from a local memory and perform matching processing on the target biometric feature information and the target rental feature information to obtain a target matching result. If the target matching result indicates that the target rental feature information contains rental biometric feature information that matches the target biometric feature information, the target rental object of the rental biometric feature information that matches the target biometric feature information indicated by the target matching result may be used as the target object.

[0104] In the above embodiment, the target terminal matches the target biometric information and the target rental feature information to obtain a target matching result. When the target matching result indicates that there is rental biometric information matching the target biometric information in the target rental feature information, the target rental object corresponding to the target matching result is used as the target object. This eliminates the need to request the rental biometric information of other rental objects other than the target rental feature information from the target server, thereby reducing the number of interactions between the target terminal and the target server, and the matching process does not need to rely on the network, thereby improving the feature matching efficiency. Secondly, it can avoid the situation where the biometric information is attacked and leaked during the interaction process, thereby improving the security of the system.

[0105] In a specific embodiment, the above method may further include:

[0106] If no preset biometric feature is found in any of the multiple images to be identified, a second preset prompt page is displayed;

[0107] acquiring at least one target biometric image;

[0108] extracting collected biometric information corresponding to the target object based on at least one target biometric image;

[0109] Accordingly, the target biometric information and the rental biometric information corresponding to the multiple rental objects are matched to obtain the target object corresponding to the target biometric information, including:

[0110] The collected biometric information is matched with the rental biometric information corresponding to the plurality of rental objects to obtain the target object.

[0111] In a specific embodiment, the second preset prompt page can be used to prompt the target object to collect at least one target biometric image. The at least one target biometric image can be an image containing the biometric characteristics of the target object.

[0112] In a specific embodiment, when the above-mentioned second recognition result indicates that none of the multiple images to be recognized have the preset biometric features, a second preset prompt page is displayed to prompt the target object to move the corresponding part to be collected to the preset area, so that the image acquisition module can collect at least one target biometric image.

[0113] In a specific embodiment, the collected biometric information corresponding to the target object may refer to the biometric information of the target object obtained by re-collection.

[0114] In a specific embodiment, a third target extraction image can be selected from at least one target biometric image based on preset image selection conditions; accordingly, feature extraction processing can be performed on the above-mentioned third target extraction image to obtain the collected biometric information corresponding to the target object.

[0115] In a specific embodiment, the collected biometric information and the rental biometric information corresponding to each rental object are matched to obtain the object feature information corresponding to the collected biometric information; accordingly, the rental object corresponding to the object feature information obtained by the above matching can be used as the target object.

[0116] S207: Sending a return instruction for the target object to the target server, so that the target server updates the target interaction state corresponding to the target object to a stop-billing state.

[0117] In a specific embodiment, the return instruction may be used to instruct the target server to update the target interaction state.

[0118] In a specific embodiment, the target interaction state may refer to the rental state of the newly added mobile power bank rented by the target object. The target interaction state may include a rental billing state, a stop billing state, or a returned state. The stop billing state may be used to indicate that the corresponding preset mobile power bank is in a state where billing has stopped and the return detection result is awaited.

[0119] In a specific embodiment, the target terminal may send a return instruction carrying object identification information corresponding to the target object to the target server; upon receiving the return instruction, the target server may update the target interaction state corresponding to the target object to a stop billing state.

[0120] In a specific embodiment, the return instruction may include a first return instruction. The first return instruction may include target biometric information.

[0121] In a specific embodiment, the above step S207 may include:

[0122] When the target matching result indicates that there is no rental biometric information matching the target biometric information in the target rental feature information, a first return instruction is sent to the target server, so that the target server matches the target biometric information and the rental biometric information corresponding to multiple rental objects, obtains the target object corresponding to the target biometric information, and updates the target interaction status to a stop billing status.

[0123] In a specific embodiment, when the target matching result indicates that there is no rental biometric information matching the target biometric information in the local memory of the target terminal, the target terminal can send a first return instruction carrying the target biometric information to the target server; accordingly, when the target server receives the above-mentioned first return instruction, it can obtain the rental biometric information corresponding to multiple rental objects from the cloud. Then, the target server can match the target biometric information with the rental biometric information corresponding to the multiple rental objects to obtain the target object corresponding to the target biometric information, and can update the target interaction state corresponding to the target object to the stop billing state. Specifically, in the process of any rental object renting a preset mobile power supply, the rental biometric information corresponding to any of the above rental objects can be stored in the local memory of the terminal corresponding to the above-mentioned preset mobile power supply, and the rental biometric information corresponding to any of the above rental objects can be uploaded to the cloud storage.

[0124] In a specific embodiment, the return instruction may include a second return instruction. The second return instruction may include the target biometric information and first object identification information corresponding to the target object. The first object identification information may refer to the object identification information corresponding to the target object matched by the target terminal based on the target rental feature information stored in the corresponding local memory.

[0125] In a specific embodiment, the above step S207 may include:

[0126] A second return instruction is sent to the target server so that the target server matches the target biometric information with the rental biometric information corresponding to the multiple rental objects, obtains the second object identification information corresponding to the target biometric information, and updates the target interaction state to a stop billing state when the second object identification information is the same as the first object identification information.

[0127] In a specific embodiment, the second object identification information may refer to the object identification information corresponding to the target object matched by the target server based on the rented biometric information stored in the cloud.

[0128] In a specific embodiment, if the target matching result indicates that the target rental feature information contains rental biometric information that matches the target biometric information, the target terminal may use the rental biometric information that matches the target biometric information in the target rental feature information as the first object identification information; the target terminal may send a second return instruction carrying the first object identification information to the target server. Upon receiving the second return instruction, the target server may match the target biometric information with the rental biometric information corresponding to multiple rental objects to obtain second object identification information corresponding to the target biometric information; if the second object identification information is identical to the first object identification information, the target server may update the target interaction status to a stop-billing status.

[0129] In a specific embodiment, the above method may further include:

[0130] Receive the return confirmation instruction sent by the target server;

[0131] Display the return confirmation result.

[0132] In a specific embodiment, the return confirmation instruction may be sent by the target server when the return detection result sent by the target mobile power device is the first detection result. The return confirmation instruction may include the device identification information corresponding to the target mobile power device and the power identification information of the newly added mobile power. The return detection result may be obtained by the target mobile power device performing a return detection on the newly added mobile power after receiving the return detection instruction sent by the target server. The return detection instruction may be sent by the target server when receiving the return instruction. The return confirmation instruction may include the return confirmation result corresponding to the newly added mobile power. The return detection result may include the first detection result and the second detection result; the first detection result may be used to indicate that the above-mentioned newly added mobile power has been returned to the target mobile power device; the second detection result may be used to indicate that the above-mentioned newly added mobile power has not been returned to the target mobile power device. The return confirmation result may be used to indicate that the newly added mobile power is in a returned state.

[0133] In a specific embodiment, when the target terminal receives a return confirmation instruction carrying a return confirmation result sent by the target server, the target terminal can display the above return confirmation result based on the display module of the target terminal to prompt that the newly added mobile power supply is in a returned state.

[0134] In a specific embodiment, the above method may further include:

[0135] Receive unreturned instructions sent by the target server;

[0136] The first preset prompt page is displayed.

[0137] In a specific embodiment, the target server may send the non-return instruction when receiving the second detection result of the return detection result sent by the target mobile power device. The non-return instruction may be used to indicate that the newly added mobile power supply has not been returned to the target mobile power device.

[0138] In a specific embodiment, the first preset prompt page can be used to prompt the target object to return the rented mobile power supply corresponding to the target object.

[0139] In a specific embodiment, when the target terminal receives the non-return instruction sent by the target server, it can display a first preset prompt page based on the display module of the target terminal to prompt the target object to return the rented mobile power supply corresponding to the target object.

[0140] In a specific embodiment, when the first preset prompt page is displayed, the target object can take out the above-mentioned newly added mobile power supply and re-insert the above-mentioned newly added mobile power supply into any vacant power supply placement port in the target mobile power supply device; accordingly, when the target object re-inserts the newly added mobile power supply into any vacant power supply placement port of the target mobile power supply device, the target mobile power supply device can re-perform a return detection on the newly added mobile power supply, and when the return detection result is the first detection result, the first detection result can be sent to the target server, so that the target server, upon receiving the first detection result, sends a return confirmation instruction to the target terminal to prompt that the newly added mobile power supply is in a returned state.

[0141] In the above embodiment, during the process of a target subject placing a newly added power bank into any vacant power bank slot of a target power bank device, an image of a preset area is captured to obtain multiple images to be identified, wherein the preset area is an area near the multiple power bank slots of the target power bank device. This allows for image capture during the process of returning the newly added power bank. Furthermore, upon identifying that at least one of the multiple images to be identified contains a preset biometric feature, target biometric information corresponding to the target subject is extracted based on the at least one image to be identified, thereby enabling biometric capture of the target subject during the process of returning the newly added power bank. Subsequently, the target biometric information is matched with the rental biometric information corresponding to the multiple rental subjects to obtain the target subject corresponding to the target biometric information. This allows for matching the biometric features of the target subject, thereby determining the rental subject corresponding to the newly added power bank. A return instruction for the target subject is then sent to a target server, causing the target server to update the target interaction status corresponding to the target subject to a stopped billing state. This avoids the situation where a power bank is placed but backend billing is still ongoing, effectively assisting in determining the return of the power bank, and thereby improving the user experience.
