Description
Technical Field
[0001] This invention relates to the technical field of intelligent suitcase item planning and placement method and system, and particularly to an intelligent suitcase item planning and placement method and system. Background Technology
[0002] Traditional vehicle trunk placement relies on user experience and judgment, requiring repeated trial and error to adjust item positions, which is time-consuming and laborious. Irregularly shaped items are difficult to arrange effectively, resulting in insufficient space utilization. Furthermore, when the trunk is cluttered, the overall center of gravity may shift, or items may be compressed, potentially causing noise or damage while driving. For example, haphazardly stacked items often lead to wrinkled clothing, damaged electronics, or wasted time searching for items due to disorganization. While existing smart trunks offer features like location tracking and weighing, they lack systematic optimization of the packing process, failing to address core pain points such as disorganized item categorization and inefficient space allocation. Therefore, a smart trunk item planning and placement method and system are urgently needed to solve these existing technological problems. Summary of the Invention
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a method and system for planning and placing items in an intelligent suitcase.
[0004] In a first aspect, embodiments of the present invention provide a method for planning and placing items in an intelligent suitcase, including:
[0005] Obtain the user's item placement instructions, scan the items to be placed, and obtain the characteristic data of the items to be placed;
[0006] Obtain the remaining space data of the suitcase, and perform space matching calculations based on the characteristic data of the items to be placed and the remaining space data of the suitcase to obtain the optimal placement scheme for the items to be placed.
[0007] The optimal placement scheme for the items to be placed is presented to the user in multiple modes, and the user plans and places the items based on the optimal placement scheme.
[0008] Furthermore, the luggage to be placed is scanned to obtain its feature data. Specific methods include: scanning all items using external LiDAR and roof-mounted binocular cameras to obtain the size of each item, and analyzing the material type and weight estimation results of the items based on a CNN classification model.
[0009] Furthermore, after obtaining the size, material, and estimated weight of the item to be placed, the system will perform data fusion on the item's feature data, reconstruct the item's three-dimensional data, obtain the item's three-dimensional reconstruction result, and send the item's three-dimensional reconstruction result to the user's vehicle system or mobile APP through the spatial engine.
[0010] Furthermore, after the 3D reconstruction results of the item are sent to the user's vehicle infotainment system or mobile app, the user can view and confirm whether the scanned material and estimated weight are correct on the vehicle infotainment system or mobile app; if the scanned material and estimated weight are incorrect, the user can modify the corresponding information in the pop-up interface on the vehicle infotainment system or mobile app.
[0011] Furthermore, a spatial matching calculation is performed using an improved BLF algorithm on the feature data of the items to be placed and the remaining space data of the suitcase. Specific methods include:
[0012] Initialize the remaining space list, divide the remaining space of the suitcase into multiple three-dimensional rectangular regions, and record the coordinate range, remaining size and load-bearing capacity of each region;
[0013] The items are sorted according to the placement rules, which include the item's own attribute rules and user-preset placement rules.
[0014] To place an item, first select candidate remaining space, traverse the remaining space list, and filter out spaces that meet the size and weight constraints; then filter suitable spaces based on the shape of the item; next, evaluate the placement position by using the bottom left alignment principle; finally, update the remaining space. After the item is placed, divide the original remaining space into new subspaces, update the remaining space list, delete spaces that are completely occupied, and add newly generated subspaces.
[0015] Perform iterative optimization, repeatedly placing items until all items are placed or no feasible solution is found.
[0016] Furthermore, when performing spatial matching calculations, constraint adjustment priorities are added. These constraints include at least: fragile item pressure resistance constraint adjustment, center of gravity stability constraint adjustment, and ease of retrieval constraint adjustment. After adding constraint adjustment priorities, the stability and space utilization of the evaluation placement location are optimized according to the constraint adjustment priorities. When the item is heavy, the remaining space at the bottom is selected first. When the item is fragile, the shock-absorbing layer or area with less pressure is selected first. The fragmentation degree of the remaining space after the item is placed is calculated, and the placement scheme with the least fragmentation is selected.
[0017] Furthermore, the optimal placement scheme for the items to be placed is presented to the user via video and voice. Specifically, the method of presenting the optimal placement scheme via video includes: transmitting the optimal placement scheme to be placed to the vehicle's infotainment screen for display, generating a 3D semi-transparent trunk model on the screen; numbering the order in which the items are placed, and displaying the arranged items on the 3D semi-transparent trunk model; highlighting prohibited areas with a special color; and calculating and displaying the distribution of the center of gravity and pressure of the arranged luggage in the 3D trunk model.
[0018] Secondly, the present invention also discloses an intelligent suitcase item placement system, characterized in that it includes: a unit for acquiring feature data of items to be placed, a unit for calculating the optimal placement scheme, and a unit for displaying the optimal placement scheme; wherein:
[0019] The item feature data acquisition unit is used to acquire the user's item placement instruction, scan the item to be placed, and obtain the item feature data.
[0020] The optimal placement scheme calculation unit is used to obtain the remaining space data of the suitcase, perform space matching calculation based on the characteristic data of the items to be placed and the remaining space data of the suitcase, and obtain the optimal placement scheme of the items to be placed.
[0021] The optimal placement scheme display unit is used to display the optimal placement scheme of the item to be placed to the user in multiple modes, and the user plans and places the item based on the optimal placement scheme.
[0022] Thirdly, the present invention also discloses an electronic device, comprising:
[0023] One or more processors;
[0024] Memory, used to store one or more programs;
[0025] When the one or more programs are executed by the one or more processors, the one or more processors implement the placement method.
[0026] Fourthly, the present invention also discloses a computer-readable medium storing a computer program, characterized in that the computer program, when executed by a processor, implements the steps in the placement method.
[0027] This invention provides a smart suitcase item placement planning method. It obtains user item placement instructions, scans the items to be placed to obtain their characteristic data, acquires remaining suitcase space data, and performs space matching calculations based on the item characteristic data and remaining space data to obtain the optimal placement scheme. The optimal placement scheme is then displayed to the user in multiple modes, allowing the user to plan and place items accordingly.

Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0032] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.
[0033] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.
[0034] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.
[0035] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.
[0036] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.
[0037] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a method and system for planning and placing items in an intelligent suitcase.
[0038] This embodiment discloses a method for planning and placing items in an intelligent suitcase, such as... Figure 1 ,include:
[0039] S100. Obtain the user's item placement instruction, scan the item to be placed, and obtain the feature data of the item to be placed; in this embodiment, the luggage to be placed is scanned to obtain the feature data of the luggage to be placed. The specific method includes: scanning all items through the vehicle's external lidar and roof-mounted binocular camera to obtain the size of each item, and analyzing the material type and weight estimation results of the item based on the CNN classification model.
[0040] Specifically, when a user has a lot of luggage to store in the trunk, they can input the command for intelligent luggage placement planning into the space optimization engine via voice or a mobile app. Upon receiving the command, the space optimization engine controls the external LiDAR and roof-mounted dual-lens camera to scan all the luggage. The scan results, including the dimensions of the items (length × width × height), the material type analyzed using a CNN classification model, and weight estimation, are output to the space optimization engine.
[0041] In this embodiment, after obtaining the size, material, and estimated weight of the item to be placed, data fusion is performed on the item's feature data to reconstruct its three-dimensional data, resulting in a three-dimensional reconstruction result. This result is then sent to the user's in-vehicle infotainment system or mobile app via a spatial engine. Once the three-dimensional reconstruction result is sent to the user's in-vehicle infotainment system or mobile app, the user can view and confirm whether the scanned material and estimated weight are correct. If the scanned material or estimated weight is incorrect, the user can modify the corresponding information through a pop-up interface on the in-vehicle infotainment system or mobile app.
[0042] Specifically, after receiving the object's dimensions, material, and estimated weight, the spatial engine performs data fusion and reconstructs the object's 3D data internally. The scan results are then sent to the vehicle's infotainment system or a mobile app. Users can view and confirm the accuracy of the scanned material, estimated weight, etc., on the infotainment system or mobile app. If the scanned material or estimated weight is incorrect, the user can input relevant information in a pop-up interface on the infotainment system or mobile app. The user's input information is then transmitted to the spatial engine.
[0043] S200. Obtain the remaining space data of the trunk, and perform space matching calculations based on the characteristic data of the items to be placed and the remaining space data of the trunk to obtain the optimal placement scheme for the items to be placed; specifically, the trunk's ToF sensor scans the dimensions of the trunk or the remaining space dimensions (if there are other items in the trunk) and outputs them to the space engine. After receiving the scanned dimensions of the trunk space, the space engine performs trunk space modeling within the engine. After the space engine completes the modeling of the relevant items and trunk space, it performs space matching calculations based on the dimensions of the items and the trunk space.
[0044] In this embodiment, a spatial matching calculation is performed using an improved BLF algorithm on the feature data of the items to be placed and the remaining space data of the suitcase. The specific method includes:
[0045] Initialize the remaining space list, divide the remaining space of the suitcase into multiple three-dimensional rectangular regions, and record the coordinate range, remaining size and load-bearing capacity of each region;
[0046] The items are sorted according to placement rules, which include rules based on the items' inherent attributes and user-preset placement rules. For example, users can input the type of items on the vehicle's infotainment system or mobile app, such as whether the glass is fragile, cannot be subjected to heavy pressure, or needs to be frequently accessed. This information is also input and transmitted to the spatial engine.
[0047] To place an item, first select candidate remaining space, traverse the remaining space list, and filter out spaces that meet the size and weight constraints; then filter suitable spaces based on the shape of the item; next, evaluate the placement position by using the bottom left alignment principle; finally, update the remaining space. After the item is placed, divide the original remaining space into new subspaces, update the remaining space list, delete spaces that are completely occupied, and add newly generated subspaces.
[0048] Perform iterative optimization, repeatedly placing items until all items are placed or no feasible solution is found.
[0049] In some preferred embodiments, when performing spatial matching calculations, constraint adjustment priorities are added. These constraints include at least: fragile item pressure resistance constraint adjustment, center of gravity stability constraint adjustment, and ease of retrieval constraint adjustment. After adding constraint adjustment priorities, the stability and space utilization of the evaluated placement location are optimized according to the constraint adjustment priorities. When the item is heavy, the remaining space at the bottom is selected first. When the item is fragile, the shock-absorbing layer or area with less pressure is selected first. The fragmentation degree of the remaining space after the item is placed is calculated, and the placement scheme with the least fragmentation is selected.
[0050] Specifically, the spatial matching calculation employs an improved BLF algorithm (Bottom-Left-Fill with Genetic Optimization), increasing space utilization to over 92% and reducing calculation time to less than 3 seconds (for a scenario with 10 items). During spatial matching calculation, constraints are prioritized: protection against crushing fragile items (e.g., glass items should be placed on the top layer), center of gravity stability (XYZ axis moment balance equations), and ease of access (frequently used items should be placed near openings). This is combined with information input by the user on the vehicle's infotainment system or mobile app for further evaluation.
[0051] S300. The optimal placement scheme for the items to be placed is displayed to the user in multiple modes, and the user plans and places the items based on the optimal placement scheme.
[0052] In this embodiment, the optimal placement scheme for the items to be placed is displayed to the user via video and audio. Specifically, the method of displaying the optimal placement scheme via video includes: transmitting the optimal placement scheme to the vehicle's infotainment screen for display; generating a 3D semi-transparent trunk model on the vehicle's infotainment screen; numbering the order in which the items are placed; displaying the arranged items on the 3D semi-transparent trunk model; highlighting prohibited areas with a special color; and calculating and displaying the distribution of the center of gravity and pressure of the arranged luggage in the 3D trunk model.
[0053] In this embodiment, the optimal placement scheme for the items to be placed is displayed to the user via voice. Specifically, the spatial engine generates text information about the placement order and transmits it to the vehicle's voice system. Upon receiving the text, the voice system provides voice guidance, such as: "Please place the blue suitcase (60x40x30cm) at the bottom; place the cat carrier in the groove on the left side panel; do not place heavy objects on the brown suitcase." The user can then follow the voice guidance to place the items in the suitcase.
[0054] This embodiment provides a smart suitcase item placement planning method. By obtaining the user's item placement instructions, the method scans the items to be placed to obtain their characteristic data; it also obtains the remaining space data in the suitcase, and performs space matching calculations based on the item characteristic data and the remaining space data to obtain the optimal placement scheme for the items; the optimal placement scheme is then displayed to the user in multiple modes, allowing the user to plan and place their items accordingly. This invention achieves an integrated solution for item size recognition, space matching calculation, and placement strategy generation, automatically generating placement schemes and providing them to the user, saving time and manpower, maximizing suitcase space utilization, and monitoring the overall center of gravity of the items to provide safety reminders and assurances.
