[0063] Please refer to Figure 3 , Figure 3 is a flowchart of the projection-based interactive unit conversion memory enhancement method in an embodiment. It should be noted that the present specification provides method operation steps as described in the embodiments or flowcharts, but more or fewer operation steps can be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one of the many execution orders, and does not represent the only execution order. In actual system or product execution, the method order can be executed in sequence or in parallel (such as parallel processor or multi-threaded processing environment). As shown in Figure 3 The flowchart at least includes the following steps 310:

[0064] Step 310: Projecting a unit conversion image at a first position corresponding to a plurality of article display cabinets, the unit conversion image displaying a unit conversion relationship formula, the unit conversion relationship formula being used to represent the conversion relationship between a plurality of unit symbols, the plurality of unit symbols corresponding one-to-one to the articles stored in the plurality of article display cabinets; the unit conversion relationship formula further comprising unit values corresponding to the plurality of unit symbols respectively; the projection position of the unit symbol is in the surrounding area of the corresponding article display cabinet.

[0065] A plurality of article display cabinets can be pre-placed in a space, and different articles can be respectively stored in the plurality of article display cabinets. The articles can be articles with unit symbols, and the unit symbols refer to basic units for measurement. The unit symbols of the articles are generally used to quantitatively represent the size of the same quantity, and the same quantity refers to a set of quantities that can be arranged in order of size and are related to each other, and the same quantity has the same unit symbol. For example, the unit symbol corresponding to a hard disk is TB, the unit symbol corresponding to a U disk (USB flash disk) is GB, and the unit symbol corresponding to an SD card (Secure Digital Memory Card) is MB.

[0066] Further, the unit categories corresponding to articles of different categories can be different. For example, the unit category corresponding to articles of a storage device category can be a storage space unit, and the articles of the storage device category can include but are not limited to hard disks, U disks, SD cards, etc., and the corresponding unit symbols can be TB, GB, and MB, respectively. Alternatively, the unit category corresponding to articles of a money category can be an amount unit, and the articles of the money category can include but are not limited to renminbi, US dollars, and euros, and the corresponding unit symbols can be yuan, US dollars, and euros, respectively. Alternatively, the unit category corresponding to articles with length characteristics can be a length unit, and the articles with length characteristics can include but are not limited to tables, pencils, and bottle caps, and the corresponding unit symbols can be meters (m), decimeters (dm), and centimeters (cm), respectively.

[0067] Further, the unit symbols corresponding to articles of the same category can be converted with each other.

[0068] The projection device can project a unit conversion image at a first position corresponding to the plurality of article display cabinets.

[0069] The first position refers to a position at which the projection device projects the unit conversion image in a real space, and the first position can be above the plurality of article display cabinets or below the plurality of article display cabinets, which is not limited herein.

[0070] The projection of the unit conversion image can include a unit conversion relationship, and the unit conversion relationship can be used to represent the conversion relationship between the plurality of unit symbols. The conversion relationship between the plurality of unit symbols refers to the relationship between different unit symbols converted with each other through a certain conversion ratio.

[0071] The plurality of unit symbols in the unit conversion relationship can correspond to the articles stored in the plurality of article display cabinets one by one, and the projection position of the unit symbols is in the surrounding area of the corresponding article display cabinet.

[0072] Further, the unit conversion relationship also includes unit values corresponding to the plurality of unit symbols respectively, wherein the unit value refers to a specific numerical value, and the numerical value is followed by a unit symbol used to represent the category of the object represented by the numerical value.

[0073] In some embodiments, the unit values can be pre-set, such as pre-setting the unit value corresponding to TB as 1 and the unit value corresponding to GB as 1024. The unit values can also be configured by user adjustment, such as adjusting the unit value corresponding to TB as 2 or adjusting the unit value corresponding to GB as 1025, which is not limited herein.

[0074] The unit values are determined according to the conversion relationship between the unit symbols. After the unit value corresponding to a certain unit symbol is changed, the unit values corresponding to other unit symbols are also changed accordingly according to the conversion relationship and the changed unit value corresponding to the certain unit symbol. For example, when the unit value corresponding to TB is changed from 1 to 2, according to the conversion rule and the changed unit value corresponding to TB, the unit value corresponding to GB is changed to 2048 and the unit value corresponding to MB is changed to 2048*1024.

[0075] As shown in Figure 4 , the display schematic diagram of the unit conversion image provided in an embodiment is shown in Figure 4 . Figure 4 In the display schematic diagram, the projection position 401 of the unit symbol corresponding to the object 1 can be located below the object display cabinet storing the object 1, the projection position 402 of the unit symbol corresponding to the object 2 can be located below the object display cabinet storing the object 2, the projection position 403 of the unit symbol corresponding to the object 3 can be located below the object display cabinet storing the object 3, and the first position 404 corresponding to the plurality of object display cabinets can be located below the plurality of object display cabinets. The projection device can project the unit conversion image at the first position 403. Further, the first position 403 can be determined by the projection position 401, the projection position 402 and the projection position 403. The unit conversion image includes the unit conversion formula, and the unit conversion formula includes the unit values corresponding to the unit symbols in addition to the unit symbols corresponding to the respective objects, such as the unit value corresponding to TB being 1, the unit value corresponding to GB being 1024, and the unit value corresponding to MB being 1024*1024.

[0076] In some embodiments, in the projected set of unit symbols capable of being converted to each other, the unit symbol representing a larger unit can have a relatively large size displayed at the projection position corresponding thereto. The display size can be represented by the area occupied by the unit symbol in the unit conversion image. As shown in Figure 5 , the storage space of TB is larger than the storage space of GB, which is larger than the storage space of MB, and in Figure 5In this context, TB has a larger display size than GB, which in turn has a larger display size than MB. By displaying different unit symbols at their corresponding projection positions with different sizes, users can quickly distinguish the unit sizes of different unit symbols under the same measurement standard.

[0077] In some embodiments, different unit symbols can be represented by different colors. For example... Figure 6 As shown, TB is displayed in black, GB in gray, and MB in a lighter gray than GB. By displaying different unit symbols in different colors, users can quickly distinguish between them, improving the intuitiveness of the unit conversion image. Optionally, TB and GB can be the same color, different from MB. Using the color of a particular unit symbol to distinguish it from other unit symbols in the unit conversion image can highlight that unit symbol, making it easier for users to quickly view specific unit symbols.

[0078] In this embodiment, unit conversion images are projected at first positions corresponding to multiple item display cabinets. The unit conversion images display unit conversion relationships, which are used to characterize the conversion relationships between multiple unit symbols. Each unit symbol corresponds one-to-one with an item stored in a multiple item display cabinet, and the projection position of the unit symbol is located in the surrounding area of ​​the corresponding item display cabinet. The unit conversion relationship also includes the unit values ​​corresponding to each of the multiple unit symbols. The unit symbols corresponding to the items can be projected into the surrounding area of ​​the item display cabinet, and the conversion relationships between each unit symbol are displayed intuitively, enhancing the intuitiveness of unit conversion and making the learning process more vivid and interesting. This effectively improves the user's learning enjoyment and efficiency, and makes it easier for the user to find the unit symbol of the corresponding item in each item display cabinet, thus improving the user experience.

[0079] In some embodiments, such as Figure 7 As shown, a projection-based interactive unit conversion memory enhancement method is provided, which includes the following steps:

[0080] Step 710: Obtain the item information corresponding to the items stored in each item display case.

[0081] Optionally, the item information includes, but is not limited to, the item name, the item unit, and the item purpose, etc., without specific limitations.

[0082] In some embodiments, the item information is pre-stored in the information storage system of the projection device, and the required item information can be directly obtained from the information storage system, and the item information carries the identification information of the corresponding item display cabinet. In the case of multiple item display cabinets, the projection device pre-stores a library of identification information of multiple item display cabinets. When the item information of a certain item display cabinet is required, the projection device matches and compares the identification information of the item display cabinet with the corresponding identification information in the item information library one by one, so as to obtain the item information stored in the item display cabinet. Since the item information is pre-verified and stored in the information storage system, the accuracy of the item information is ensured, and the management of the item information is facilitated.

[0083] In some embodiments, the item information can be obtained by capturing the image of the item stored in the item display cabinet through the camera in the projection device, obtaining the item image, and identifying the item contained in the captured image. The item information is obtained by identifying and analyzing the captured image, which does not depend on pre-stored data, can identify and process unknown or newly appeared items, and improves the flexibility and applicability of the system.

[0084] Step 720, determining the unit symbol corresponding to each item according to the item information corresponding to each item.

[0085] It can be understood that the item information corresponding to each item contains the unit symbol of the item, and the unit symbol corresponding to each item is determined from the item information corresponding to each item.

[0086] It should be noted that the unit symbol corresponding to each item can be determined according to the size and / or capacity of the item in its use field and the standardization requirement of the use field. Taking TB, GB and MB as examples, the use field is the computer field, and the selection of the unit symbol mainly depends on the size of the storage capacity and the industry convention and standardization requirement. TB is usually used to represent a very large storage capacity, such as enterprise-level hard disk, data center storage device or cloud storage service, etc. When the storage capacity reaches or exceeds 1000 GB, it is more intuitive and convenient to use TB as the unit. GB is suitable for medium-sized storage devices, such as personal computer hard disk, mobile hard disk, USB flash disk, etc. MB is used when the storage capacity is small, such as the size of some small files or the memory size in early computer systems. Therefore, hard disks, USB flash disks and SD cards can be placed in the item display cabinet, and the corresponding unit symbols are TB, GB and MB, respectively.

[0087] Step 730, generating a unit conversion relationship according to the unit symbol corresponding to each item, and generating a unit conversion image containing the unit conversion relationship.

[0088] After determining the unit symbol corresponding to each item, a unit conversion relationship is generated according to the unit symbol corresponding to each item, and a unit conversion image containing the unit conversion relationship is generated. In the unit conversion relationship, in addition to the unit symbol corresponding to each item, the unit value corresponding to each unit symbol and the relationship connector are also included.

[0089] Optionally, the unit value can be automatically configured according to a conventional standard, or manually preset by the user. In the conventional standard, in order to speed up the conversion calculation between units and avoid the use of decimals or fractions, a unit symbol representing a larger range is usually assigned a smaller unit value, so that the values of other smaller units are sequentially increased by a fixed multiple, thereby establishing an intuitive and efficient unit conversion relationship. By manually presetting the unit value, the user can customize the unit conversion relationship in the case where a specific unit value is set for a certain unit symbol. Taking TB, GB, and MB as examples, in the conventional standard, the unit value corresponding to the unit symbol TB representing the largest storage capacity is preset to 1, so that the unit value corresponding to GB is 1024, and the unit value corresponding to MB is 1024*1024, thereby generating the conversion relationship 1TB=1024GB=1024*1024MB. In the case of manual presetting by the user, the unit value corresponding to GB can be set to 1, and the conversion relationship generated at this time is 1 / 1024TB=1GB=1024MB.

[0090] In some embodiments, the unit conversion relationship includes at least one sub-conversion relationship, and the sub-conversion relationship is used to represent the conversion relationship between the unit symbols corresponding to the items stored in two adjacent item display cabinets. Taking the conversion relationship 1TB=1024GB=1024*1024MB as an example, it contains three sub-conversion relationships: 1TB=1024GB, 1024GB=1024*1024MB, and 1TB=1024*1024MB. Among them, 1TB=1024GB is used to represent the conversion relationship between TB and GB, 1024GB=1024*1024MB is used to represent the conversion relationship between GB and MB, and 1TB=1024*1024MB is used to represent the conversion relationship between TB and MB. Through the design of the sub-conversion relationship, the projection device can flexibly handle the conversion requirements between various units, and it is also convenient for the user to view the conversion relationship between any two unit symbols, thereby improving the user experience.

[0091] At step 740, a unit conversion image is projected at the first positions corresponding to the plurality of product display cabinets. The unit conversion image displays a unit conversion relationship formula. The unit conversion relationship formula is used to represent the conversion relationship between a plurality of unit symbols. The plurality of unit symbols correspond to the products stored in the plurality of product display cabinets one by one. The unit conversion relationship formula further includes unit values corresponding to the plurality of unit symbols respectively. The projection position of the unit symbol is in the surrounding area of the corresponding product display cabinet.

[0092] It can be understood that after the unit conversion image containing the unit conversion relationship formula is generated, the unit conversion image can be projected at the first positions corresponding to the plurality of product display cabinets. The first positions depend on the projection positions of the unit symbols, and the projection positions of the unit symbols are in the surrounding area of the corresponding product display cabinet. The surrounding area can be the upper edge of the corresponding product display cabinet, or the lower edge of the corresponding product display cabinet, which is not limited here.

[0093] In the embodiments of the present application, the unit conversion image is projected at the first positions corresponding to the plurality of product display cabinets. The unit conversion image displays a unit conversion relationship formula. The unit conversion relationship formula is used to represent the conversion relationship between a plurality of unit symbols. The plurality of unit symbols correspond to the products stored in the plurality of product display cabinets one by one. The projection position of the unit symbol is in the surrounding area of the corresponding product display cabinet. The unit conversion relationship formula further includes unit values corresponding to the plurality of unit symbols respectively. The unit symbol corresponding to the product can be projected in the surrounding area in the product display cabinet, and the conversion relationship between the unit symbols is intuitively displayed, which enhances the intuitiveness of unit conversion, makes the learning process lively and interesting, and thus effectively improves the learning pleasure and efficiency of the user. In addition, the user can easily find the unit symbol of the corresponding product in each product display cabinet, and the user experience is improved.

[0094] Please refer to Figure 8 , Figure 8 FIG. 1 is a flowchart of determining the first positions corresponding to the plurality of product display cabinets in an embodiment. As shown in Figure 8 , the above method further includes the following steps:

[0095] At step 810, the images corresponding to the plurality of product display cabinets are captured by a camera.

[0096] Optionally, the camera can include but is not limited to a mini camera, an infrared camera, a high-pixel camera, a zoom lens camera, etc., which is not limited here.

[0097] In some embodiments, the images corresponding to the plurality of product display cabinets can be captured by the camera. The images can include the plurality of product display cabinets, the products stored in each product display cabinet, etc.

[0098] At step 820, the multiple product display cabinets contained in the image are identified to obtain the position information of each product display cabinet.

[0099] In some embodiments, after the image corresponding to the multiple product display cabinets is collected, the multiple product display cabinets contained in the image are identified to obtain the position information of each product display cabinet. Through the identification of the position information of each product display cabinet, the accurate positioning of each product display cabinet is realized, which helps to quickly find each product display cabinet.

[0100] The position information of the product display cabinet refers to the position of the product display cabinet in the display area. The position information can be represented by coordinates or positioning points. In the case of being represented by coordinates, the position information can include the coordinate origin and the position in the horizontal direction and the vertical direction.

[0101] Optionally, the coordinate origin can be the starting position of the first product display cabinet on the left upper side, or the center projection point of the projection device, which is not specifically limited here.

[0102] Optionally, there are various image recognition methods, including but not limited to shape-based recognition method, edge detection, deep learning method, attention mechanism, etc., which are not specifically limited here.

[0103] The shape-based recognition method is a technology that uses the geometric shape information of the target object in the image for recognition. It realizes accurate recognition of the target object through image preprocessing, shape feature extraction and shape matching steps.

[0104] Edge detection refers to detecting the places where the brightness or grayscale value in the image changes significantly, i.e., the edge part of the image, which usually corresponds to the outline of the object, the boundary of different regions, etc. It is important feature information in the image. The purpose of edge detection is to extract these edge information from the image to provide a basis for subsequent processing such as image segmentation and target recognition. The grayscale value refers to the brightness or grayscale level of each pixel in the image, while the grayscale is a quantitative representation of the brightness of the image, describing the brightness level of each pixel in the image.

[0105] The deep learning method simulates the way the human brain processes and analyzes data. By constructing a deep neural network structure, it automatically learns the complex features in the data and performs prediction, classification, recognition, etc. based on these features. For example, a convolutional neural network (CNN) is constructed to realize automatic learning and feature extraction of image data. The attention mechanism introduces a weight distribution mechanism in the neural network, so that the model can automatically learn and focus on the key areas or features in the input image.

[0106] A neural network is a mathematical or computer model consisting of a large number of interconnected nodes that perform computations. It learns by using interconnected nodes in a hierarchical structure similar to that of the human brain and is able to recognize and classify images.

[0107] Taking deep learning methods as an example, after acquiring images corresponding to multiple display cases, the images are first preprocessed. Preprocessing steps include image resizing and normalization to ensure the consistency of the input data. Next, a convolutional neural network (CNN) in deep learning is used to extract features from the preprocessed images. Based on the feature extraction, a detection framework is used to identify the display cases. The detection framework can accurately locate the position of each display case in the image using the features extracted by the CNN. Based on the output of the detection framework, the position information of each display case is obtained. This position information is usually represented in coordinate form, accurately describing the location of each display case in the image.

[0108] Step 830: Determine the projection position for each item display cabinet based on the location information corresponding to each item display cabinet; the projection position is used to project the unit symbol corresponding to the item stored in the item display cabinet.

[0109] In some embodiments, the projection position for each item display cabinet can be determined based on the acquired location information corresponding to each item display cabinet. The projection position is used to project the unit symbol corresponding to the item stored in the item display cabinet, and the projection position is located in the surrounding area of ​​the corresponding item display cabinet.

[0110] In some embodiments, after determining the location information corresponding to each item display case, the layout of multiple item display cases is analyzed to determine the space around each display case that is suitable as a projection area. This area should be large enough to clearly project the unit symbol corresponding to the item without affecting the viewer's viewing of the items in the display case or affecting the display effect of other display cases.

[0111] After determining the projection position based on the location information corresponding to each item display case, by projecting the unit symbol onto the surrounding area of ​​the item display case, users can easily see the unit symbol corresponding to the items stored in each item display case.

[0112] Taking the items stored in three display cases as examples, with the unit symbols TB, GB, and MB respectively, and the surrounding area being the area below the display cases, as follows: Figure 4 As shown, the projection position 401 of the unit symbol corresponding to item 1 shows the unit symbol TB corresponding to item 1, the projection position 402 of the unit symbol corresponding to item 2 shows the unit symbol GB corresponding to item 2, and the projection position 403 of the unit symbol corresponding to item 3 shows the unit symbol MB corresponding to item 3.

[0113] It can be understood that a projection position is arranged around each article display cabinet, and the projection position is used to project a unit symbol corresponding to an article stored in the article display cabinet. It should be noted that the unit symbols corresponding to the articles stored in the plurality of article display cabinets can be converted.

[0114] In some embodiments, when the unit symbols corresponding to the articles stored in any two article display cabinets are the same, the unit values corresponding to the articles stored in the two article display cabinets are also the same.

[0115] At step 840, a first position corresponding to the plurality of article display cabinets is determined according to the projection positions corresponding to each article display cabinet.

[0116] In some embodiments, the first position corresponding to the plurality of article display cabinets can be determined according to the projection positions corresponding to each article display cabinet. After the corresponding projection position of each article display cabinet is determined, a unit value corresponding to each unit symbol is projected in front of the unit symbol according to the unit symbol corresponding to each projection position, and a connection relationship symbol is projected between all adjacent projection positions to clearly show the logical relationship between the unit values and the unit symbols. The area occupied by each unit symbol, the unit value corresponding to the unit symbol, and each connection relationship symbol is defined as the first position.

[0117] A unit conversion image is projected in the first position, and the unit conversion image displays a unit conversion relationship formula. The unit conversion relationship formula displays the unit symbols projected in the projection positions corresponding to each article display cabinet and the unit values corresponding to the unit symbols. A connection relationship symbol is displayed between the projection positions corresponding to any two article display cabinets. The spacing between the unit symbols, the unit values, and the connection relationship symbol is determined by the size of the unit symbols, the unit values, and the connection relationship symbol.

[0118] Alternatively, the connection relationship symbol can be an equal sign or other symbols having a connection relationship, which is not specifically limited here.

[0119] The size of the unit symbols, the unit values, and the connection relationship symbol can be represented by the area occupied by the unit symbols, the unit values, and the connection relationship symbol in the unit conversion image.

[0120] Similarly, taking the unit symbols corresponding to the articles stored in the three article display cabinets as TB, GB, and MB for example. Please refer to Figure 9 , Figure 9 is a schematic diagram of the first position where the unit conversion image is located in an embodiment. As Figure 9 shown, after the unit symbols are projected and displayed in the projection positions corresponding to each article display cabinet, a unit conversion relationship formula can be generated according to the conversion relationship between the unit symbols, and the unit conversion relationship image is displayed in the first position. Figure 9The unit conversion relationship image in the first position contains the unit conversion relationship formula "1TB = 1024GB = 1024*1024MB". The unit conversion relationship formula contains unit symbols "TB, GB, and MB" and unit values "1, 1024, and 1024*1024" corresponding to each unit symbol, and uses a connection relationship symbol "=" for connection. It can be seen that in the case of smaller unit values "1, 1024", the interval between "1TB, =", and "1024GB" is larger than the interval between "1024GB, =", and "1024*1024MB". In the unit conversion relationship image, the unit symbols "TB, GB, and MB" and their corresponding unit values "1, 1024, and 1024*1024" are more visually clear and understandable through adaptive display layout. This layout design not only enhances the user experience, but also ensures the accurate display of the unit conversion relationship formula.

[0121] In the embodiments of the present application, the images of multiple product display cabinets are captured by the camera, and the position information of each display cabinet is obtained by identifying the images, and then the projection position corresponding to each display cabinet is determined, and finally the first position corresponding to the multiple display cabinets is determined. This process not only realizes the identification and positioning of the display cabinet, but also intuitively displays the unit symbols corresponding to each product around the corresponding product display cabinet through projection, improving the visualization and accessibility of information. At the same time, determining the first position provides convenience for displaying the unit conversion relationship image, which helps users quickly understand and compare the conversion relationship between different units.

[0122] In some embodiments, in the case where unit conversion cannot be performed between the unit symbols corresponding to any two products, an error information is projected and displayed at the first position. The error information is used to prompt that the unit conversion cannot be performed between the unit symbols corresponding to the two products.

[0123] The case where unit conversion cannot be performed usually occurs when the physical quantities represented by the unit symbols corresponding to two products are different and there is no explicit conversion relationship. For example, the unit of one product is "meter" (length unit), and the unit of another product is "terabyte" (TB) (storage space unit). Since they measure completely different physical quantities, there is no direct conversion relationship between them. In this case, if an attempt is made to convert between the unit symbols of the two products, the projection device can display an error information at the first position to prompt the user that the conversion between the two units cannot be performed.

[0124] Optionally, the display of the error information can be a pop-up window or an error icon, which is not limited here.

[0125] Please refer to Figure 10 , Figure 10This is a schematic diagram illustrating the display of error information at a first location in one embodiment. For example... Figure 10 As shown, item 1 corresponds to the unit symbol "TB", item 2 corresponds to the unit symbol "GB", and item 3 corresponds to the unit symbol "cm". It is understandable that the unit symbols "TB" and "GB" can be converted, generating the unit conversion formula "1TB = 1024GB". However, the unit symbols "TB" and "cm", and "GB" and "cm" cannot be converted. Error messages can be displayed in error display area 701, such as... Figure 10 In the error message 1001, it displays "Error! TB and cm, GB and cm cannot be converted".

[0126] In this embodiment, an error message is displayed when any two unit symbols cannot be converted, enhancing the accuracy and reliability of unit conversion information and avoiding misleading information caused by incorrect unit conversion. It also improves the user experience, allowing users to quickly identify unit symbols that cannot be converted to each other.

[0127] In some embodiments, at a second position corresponding to each unit value, a value adjustment control corresponding to each unit value is projected and displayed; in response to a trigger operation on the first value adjustment control, the adjusted unit value corresponding to the first value adjustment control is obtained; the first value adjustment control can be any value adjustment control; based on the adjusted unit value corresponding to the first value adjustment control and the conversion relationship between multiple unit symbols, other unit values ​​in the unit conversion image are adjusted.

[0128] The second position refers to the location where the numerical adjustment controls are displayed, which is situated in the area surrounding each item display case.

[0129] Optionally, the second position can be located on the outer perimeter of the display case or on the outer perimeter of the unit value corresponding to the unit symbol projected at the projection position; no specific limitation is made here.

[0130] Optionally, the numerical adjustment control can be a gear or a slider control; no specific limitation is made here.

[0131] Optionally, the trigger operation can be a gear selector or a sliding touch operation; no specific limitation is made here.

[0132] Each unit value has a corresponding second position. At each unit value's second position, a value adjustment control is projected to display the corresponding unit value. This value adjustment control can be used to adjust its corresponding unit value.

[0133] The user can operate any numerical value adjustment control through a trigger operation. The projection device can obtain an adjusted unit value corresponding to the first numerical value adjustment control in response to the trigger operation on the first numerical value adjustment control, and adjust the unit value corresponding to the first numerical value adjustment control in the projection. The first numerical value adjustment control is any numerical value adjustment control.

[0134] In some embodiments, the projection device captures the trigger gesture action of the user through the camera, and analyzes the trigger gesture action of the user by using image recognition technology. The analyzed trigger gesture action of the user is matched with a set of gesture actions for triggering the numerical value adjustment control preset in the projection device one by one. If the matching is successful, the projection device obtains the adjusted unit value of the numerical value adjustment control corresponding to the user trigger gesture action according to the analyzed trigger gesture action of the user, and adjusts the unit value corresponding to the numerical value adjustment control. If there is no matching, it means that the trigger gesture action of the user is not used to adjust the numerical value adjustment control.

[0135] After the projection device changes the unit value corresponding to the first numerical value adjustment control in the unit conversion relationship in the unit conversion image, the projection device can adjust other unit values of the unit conversion relationship in the unit conversion image according to the obtained adjusted unit value corresponding to the first numerical value adjustment control and the conversion relationship between the plurality of unit symbols.

[0136] Taking the numerical value adjustment control as a gear and the trigger operation as a dial gear as an example. Please refer to Figure 11 , Figure 11 is a schematic diagram of adjusting the unit value in an embodiment. As shown in (a) of Figure 11 , a numerical value adjustment control is arranged at each second position corresponding to a unit value. For example, a first numerical value adjustment control 1101 is arranged at the second position corresponding to the unit value "1". The first numerical value adjustment control 1101 can adjust the corresponding unit value "1". For example, the user changes the unit value "1" to "2" by dialing the first numerical value adjustment control 801. After obtaining the changed unit value "2", the related adjustment module in the projection device can adjust other unit values of the unit conversion relationship in the unit conversion image according to the changed unit value "2" and the conversion relationship between "TB", "GB", and "MB". Figure 11As shown in (b) in FIG. 11, the adjustment unit value "1024" is changed to "2048", and the adjustment unit value "1024*1024" is changed to "1024*2048". The second position corresponding to each unit value is provided with a value adjustment control, such as the first value adjustment control 1101, to allow the user to directly change the unit value by operating the control and trigger the related adjustment module in the projection device to automatically update other unit values in the unit conversion relationship formula, greatly improving the convenience and intuitiveness of user operation, and enhancing the interactivity between the user and the projection display content, making the display of unit conversion information more flexible and dynamic, and improving the overall user experience.

[0137] In the embodiments of the present application, the second position corresponding to each unit value is provided, and the value adjustment control is projected and displayed, allowing the user to directly adjust the unit value. This not only enhances the interactivity between the user and the unit conversion information, allowing the user to flexibly adjust the unit value as needed, but also ensures that other unit values can be automatically and accurately adjusted after any unit value in the unit conversion relationship formula is changed, thereby maintaining the correctness and consistency of the unit conversion relationship.

[0138] In some embodiments, the background adjustment control corresponding to the unit conversion relationship formula is projected and displayed at the third position corresponding to the plurality of article display cabinets; in response to a triggering operation on the background adjustment control, a background parameter is obtained, the background parameter including a background image or a background color of the unit conversion relationship formula; and the background of the unit conversion relationship formula in the unit conversion image is adjusted according to the background parameter.

[0139] The third position refers to the position of the background adjustment control, which is located in the surrounding area of the plurality of article display cabinets.

[0140] Optionally, the third position can be above the plurality of article display cabinets, or to the right of the plurality of article display cabinets, which is not limited here.

[0141] Optionally, the background adjustment control can be a slider or a list selection control, which is not limited here.

[0142] Optionally, the triggering operation on the background adjustment control can be sliding or clicking, etc., which is not limited here.

[0143] The third position corresponding to the plurality of article display cabinets is provided with the background adjustment control corresponding to the unit conversion relationship formula, which can be used to adjust the background in the unit conversion relationship in the unit conversion image.

[0144] The user can operate the background adjustment control through a triggering operation. The projection device can obtain a background parameter in response to the triggering operation on the background adjustment control. The background parameter includes a background image or a background color of the unit conversion relationship formula. According to the obtained background parameter, the projection device can adjust the background of the unit conversion relationship formula in the unit conversion image.

[0145] In some embodiments, the projection device captures the user's triggering gesture action through the camera, and analyzes the user's triggering gesture action by using image recognition technology. The analyzed user's triggering gesture action is matched with a set of gesture actions preset in the projection device for triggering the background adjustment control one by one. If the matching is successful, the projection device obtains the adjusted background parameter according to the analyzed user's triggering gesture action, and adjusts the background of the unit conversion formula in the unit conversion image according to the adjusted background parameter. If the matching is not successful, it indicates that the user's triggering gesture action is not used to adjust the background adjustment control.

[0146] For example, refer to Figure 12 , Figure 12 is a schematic diagram of adjusting the background of the unit conversion relationship formula in an embodiment. As shown in (a) of Figure 12 , the background adjustment control 1201 is displayed at the third position corresponding to the plurality of article display cabinets. The background adjustment control 1201 displays options for background color adjustment and background image adjustment. In response to a triggering operation on the background color adjustment control, an adjusted background color is obtained. According to the adjusted background color, the background color of the unit conversion relationship formula in the unit conversion image can be adjusted, as shown in (b) of Figure 9 . After adjusting the background color of the unit conversion relationship formula in the unit conversion image, the background color of the unit relationship conversion formula changes from white in (a) to gray in (b). Similarly, in response to a triggering operation on the background image adjustment control, an adjusted background image is obtained. The background image of the unit conversion relationship formula in the unit conversion image can be adjusted. By setting the background adjustment control 1201 at the third position corresponding to the plurality of article display cabinets, and providing options for background color adjustment and background image adjustment, the user can adjust the background color and background image of the unit conversion relationship formula in the unit conversion image according to personal preferences or environmental needs. The readability and aesthetics of the unit conversion information are improved, and the interactivity of the user interface is also enhanced.

[0147] In the embodiments of the present application, the background adjustment control is set at the third position corresponding to the plurality of article display cabinets, allowing the user to personalize the background of the unit conversion relationship image, enhancing the visual appeal and readability of the unit conversion information. Through the background adjustment control, the user can adjust the background of the unit conversion relationship formula, thereby achieving better visual presentation effect, and improving the user's visual experience.

[0148] In the embodiments of the present application, the unit conversion relationship is helped to remember by projecting the unit conversion image, the intuitiveness of unit conversion is improved, and the learning efficiency of the user is improved.
