Computer VR technology has been widely used in landscape design. This paper analyzes the auxiliary use mode and detail optimization process of this technology in landscape design, and gives the comparative experiment of indoor and outdoor landscape design. Firstly, landscape design planning and design based on VR technology; secondly, the detailed optimization process of the combination of VR and VR-GIS is analyzed; finally, aiming at the problem of poor energy-saving effect of traditional methods, the energy-saving optimization design of data acquisition system is carried out. The data collector in the data acquisition system uses the method of contrast image of visual image to collect data, so it consumes a lot of power in the process of using. Therefore, the data collector and control power system are optimized, which can effectively reduce the energy consumption. In the process of virtual image establishment, edge correlation operator is used to calculate correlation, so as to achieve low power consumption. On this basis, the auxiliary use and detail optimization in landscape design are given by using Lumion virtual reality (VR) platform. The experimental results show that the visual modeling error of this method is stable between 1 and 3%, the error is small and the stability is good; the average rendering time of batch objects is about 8.9 s, which is an efficient auxiliary use and detail optimization method for VR landscape design.

计算机VR技术已被广泛用于景观设计中。本文分析了该技术在景观设计中的辅助使用方式和细节优化过程，并给出了室内外景观设计的对比实验。首先，基于虚拟现实技术的景观设计规划设计；其次，分析了VR与VR-GIS结合的详细优化过程。最后，针对传统方法的节能效果较差的问题，进行了数据采集系统的节能优化设计。数据采集​​系统中的数据采集器采用可视图像的对比图像的方法来采集数据，因此在使用过程中会消耗大量的电能。因此，对数据收集器和控制电源系统进行了优化，可以有效降低能耗。在虚拟图像建立过程中，使用边缘相关算子来计算相关性，以实现低功耗。在此基础上，利用Lumion虚拟现实（VR）平台给出了景观设计中的辅助使用和细节优化。实验结果表明，该方法的视觉建模误差稳定在1-3％之间，误差小，稳定性好。批处理对象的平均渲染时间约为8.9 s，是VR景观设计的一种有效的辅助使用和细节优化方法。利用Lumion虚拟现实（VR）平台给出了景观设计中的辅助使用和细节优化。实验结果表明，该方法的视觉建模误差稳定在1-3％之间，误差小，稳定性好。批处理对象的平均渲染时间约为8.9 s，是VR景观设计的一种有效的辅助使用和细节优化方法。利用Lumion虚拟现实（VR）平台给出了景观设计中的辅助使用和细节优化。实验结果表明，该方法的视觉建模误差稳定在1-3％之间，误差小，稳定性好。批处理对象的平均渲染时间约为8.9 s，是VR景观设计的一种有效的辅助使用和细节优化方法。
