Through digital design to create Komatsu Garden red tourism landscape, so that the design is more scientific and convenient. Specific research conclusions are as follows. 1) Research is more efficient The OSGB model is generated through the UAV surveying and mapping operation, which can save a large amount of site survey and research time in the early stage. The designer can directly view the high-precision model of the site in the computer, which takes only 40 minutes in the process of designing aerial survey in Komatsu Park. The aerial survey of Komatsu Garden was completed. The interior industry used Dajiang Smart Map to generate a complete model, which can measure the height difference angle slope anywhere in the village to assist the design. (2) The model is more accurate In the traditional design process, the site model also needs to be designed according to CAD independent modeling. In the digital design process, the UAV aerial survey model is directly used, and the error can be controlled to within centimeters, and the model stack is designed in the later stage. The addition process is more able to completely embed Plant 1 into the scene model. (3) More accurate analysis In the past, the analysis diagram in the design process is mostly drawn by PS, AI and other software, thanks to the complete site model, through data conversion, can be directly into the plant 1 to GIS for analysis or directly to the point cloud file analysis, get. The analysis chart is more specific, diverse and accurate. (4) The program is more scientific Thanks to accurate analysis and complete model, after embedding the design scheme into the real model, the scheme can also be adjusted according to the actual site. Usually, most of the construction personnel are required to adjust the scheme according to the site. With the blessing of digital real-life model, the scheme can be more scientific and accurate. (5) Show more convenient Through various display methods, designs can be displayed in VR glasses, mobile phones, computers and other mobile terminals. While convenient display, more people's opinions and suggestions can be obtained, so that designs can enter the Internet instead of stopping with designers. Net, let the design become the design of the masses, let the design really come from the hands of the masses. (6) Meet the needs of rural reconstruction Today, with the increasing efforts of the national rural revitalization, this set of plans is very suitable for the rural renovation design. First of all, most of the rural basic data are missing and the budget is insufficient, which is made up by generating a complete model. Secondly The rural terrain is complex and the site survey is difficult. This problem can also be solved well with the help of unmanned aerial vehicles. Finally, most villages are mainly transformed, which can be realized by modifying the model, eliminating the tedious process of site model restoration.
