[0002] With the acceleration of urbanization and the continuous improvement of people's requirements for the quality of living environment, environmental art design has become increasingly important in shaping comfortable, beautiful and functional spaces. Traditional environmental art design methods usually rely on the designer's experience, hand-drawn sketches and simple two-dimensional or three-dimensional modeling software, which has many limitations in data collection, model construction, design analysis and data management.

[0003] In the data collection stage, traditional methods often have low accuracy and cannot accurately obtain key information such as space size, material properties, and pedestrian flow, resulting in an insufficiently solid design foundation. The model building process is cumbersome and time-consuming, and it is difficult to respond to design modifications in real time, which limits the designer's creativity and efficiency. Design analysis relies heavily on subjective judgment, lacks quantitative indicators and scientific evaluation methods, and is difficult to accurately evaluate the pros and cons of design solutions. In addition, data storage is scattered and chaotic, and it is difficult to find and manage, which can easily cause data loss or damage, affecting the continuity and reliability of design work.

[0079] In order to more intuitively demonstrate the advantages of the environmental art design system based on BIM technology of the present invention, the following comparison is set to compare with the traditional design method.

[0080] Comparative Example 1, Traditional Urban Park Landscape Design:

[0081] Data collection:

[0082] Using conventional measuring tools, such as tape measures and levels, the spatial dimension acquisition accuracy is about 0.1 meters;

[0083] The material attribute classification is relatively rough, with about 10 types;

[0084] The flow of people is estimated manually, which has a large error of about 20%;

[0085] Ambient noise values ​​were not collected.

[0086] Model construction:

[0087] It took about 2 days to build the model based on hand sketches and simple 3D modeling software;

[0088] The model is difficult to modify and cannot be updated in real time.

[0089] Design Analysis:

[0090] The evaluation relies on the designer's experience, lacks quantitative indicators and simulation effects, and takes a long time, about 1 week.

[0091] Data Storage:

[0092] Data is stored in a decentralized manner in the form of paper files and electronic documents, making it difficult to find and manage.

[0093] Comparative Example 2, Traditional Commercial Pedestrian Street Design:

[0094] Data collection:

[0095] Mainly relying on manual measurement, the spatial dimension accuracy is about 0.08 meters;

[0096] There are about 15 types of material attributes;

[0097] The flow of people is counted through sampling survey, with an error of about 15%;

[0098] Ambient noise values ​​were not systematically collected.

[0099] Model construction:

[0100] Using general 3D modeling software, it took about 3 days to build the initial model;

[0101] Model modification is complicated and updates are not timely.

[0102] Design Analysis:

[0103] The evaluation mainly relies on qualitative analysis and takes about 10 days, which makes it difficult to accurately evaluate the efficiency of space utilization and artistic innovation.

[0104] Data Storage:

[0105] Data storage is chaotic and lacks unified management.

[0106] Comparative Example 3, Traditional Residential Community Landscape Design:

[0107] Data collection:

[0108] With the help of simple measuring tools, the spatial dimension accuracy is about 0.07 meters;

[0109] There are about 12 types of material attributes;

[0110] The method of counting people flow is inaccurate, with an error of about 18%;

[0111] No environmental noise value was collected.

[0112] Model construction:

[0113] Using traditional modeling techniques, it takes about 2.5 days to build the model;

[0114] Model adjustments are difficult and updates are slow.

[0115] Design Analysis:

[0116] It mainly relies on subjective judgment, the evaluation period is about 8 days, and it is impossible to provide quantitative evaluation results. Data storage:

[0117] Data storage is scattered and prone to loss and damage.

[0118]

[0119]

[0120]

[0121] From the above data comparison, it can be seen that the environmental art design system based on BIM technology of the present invention is obviously superior to the traditional design method in terms of data collection accuracy, model construction efficiency, design analysis speed and accuracy, and data management.

[0122] In the implementation, it is possible to accurately collect various environmental data, quickly build and update the BIM model in real time, and provide quantitative design analysis results in a short time, providing designers with accurate and efficient design tools. At the same time, powerful data storage and management functions ensure the security and convenience of data.

[0123] In the comparison example, the traditional design method has problems such as low data collection accuracy, difficulty in model construction and modification, lack of quantitative indicators and long time consumption in design analysis, and chaotic data storage and management, which seriously affect the design quality and efficiency.

[0124] In terms of data collection, high-precision spatial dimension measurement, rich and detailed material attribute classification, accurate human flow statistics and inclusion of environmental noise values ​​provide comprehensive and accurate basic information for design. This is in sharp contrast to the rough data collection methods in traditional design methods, overcoming the defects of inaccurate and incomplete data in traditional methods, making the design basis more scientific and reliable.

[0125] In the model building phase, the system of the present invention realizes fast and efficient model generation and can respond to modifications in real time, greatly shortening the design cycle and improving work efficiency. The drawbacks of the traditional design of long modeling process and difficulty in real-time updating have been fundamentally improved here, and designers can explore and optimize design solutions more flexibly to meet customer demand changes in a timely manner.

[0126] In terms of design analysis, this system can provide quantitative evaluation results in multiple dimensions including space utilization efficiency, cost budget and artistic innovation in a short period of time, and simulate various scenarios at the same time, providing strong support for design decisions. In contrast, traditional design mainly relies on experience and subjective judgment, lacks accurate quantitative evaluation and simulation effect display, resulting in insufficient scientificity and accuracy of design decisions.

[0127] In terms of data storage, the system of the present invention not only has large-capacity storage capacity, but also achieves high-speed reading and high compression ratio, while ensuring data security and convenient management. The traditional data storage method is scattered and chaotic, which is not only difficult to find and manage, but also prone to the risk of data loss and damage.

[0128] In general, the environmental art design system of the present invention has achieved full process optimization and innovation from data collection to design analysis to results display and data storage by relying on the powerful functions of BIM technology. It has brought a new working mode and higher design quality to the field of environmental art design, and can better meet customers' diverse and high-quality needs for environmental art design.

[0129] In the future development, with the continuous advancement and application expansion of BIM technology, the system of the present invention is expected to further integrate more advanced technologies, such as artificial intelligence-assisted design, virtual reality immersive experience, etc., to create more possibilities for environmental art design. At the same time, we also expect that this system can be applied and verified in a wider range of practical projects, and continuously promote the environmental art design industry to move towards digitalization, intelligence, and efficiency, and contribute to creating a better living environment and urban landscape.
