Description

Technical Field

[0001] The present invention relates to the technical field of landscape design, and in particular to a method for restoring landscape design effects based on BIM technology. Background Art

[0002] Landscape engineering is the most widely implemented part of urban park project construction. The multi-level design and diversified use functions of park projects increase the complexity of landscape engineering design. Accurately restoring the landscape design effect is one of the key control links in the project construction process, which affects the final formation effect and use function of the entire park.

[0003] The traditional landscape effect method has the following disadvantages: 1. The traditional method restores the landscape design effect by using local effect drawings + construction plan drawings. The design effect display cannot be adjusted dynamically, is not intuitive enough, is too one-sided, and cannot display the overall project design effect;

[0004] 2. The accuracy of the local renderings is not high, and they only roughly restore the design effect. They cannot perfectly correspond to the construction plan. After the construction is implemented, there is a large deviation from the renderings;

[0005] 3. The different understandings of the drawings and renderings by the various parties involved led to a long time to finalize the project landscape design plan;

[0006] 4. During on-site implementation, it is necessary to build a landscape sample area. There will be great changes in the implementation process, resulting in waste of manpower and material resources and delays in the construction period. The final shaping effect is difficult to control, which increases construction costs and delays the construction period. The construction plan and construction proofing are roughly confirmed. The analysis efficiency is low and the analysis effect is poor, which seriously restricts the progress of the project construction. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0008] To this end, the present invention provides a method for restoring landscape design effects based on BIM technology.

[0015] Step 6: Conduct landscape dynamic analysis by adjusting different tree species, tree shapes and planting locations to further adjust the landscape design plan;

[0016] Step 7: Read the vegetation model through the dyn file and output the vegetation coordinate points;
