Three-dimensional scene dynamic modeling method and system for radio frequency simulation darkroom

Abstract

The invention discloses a three-dimensional scene dynamic modeling method and system of a radio frequency simulation darkroom. The method comprises the following steps: establishing a three-dimensional model and loading the three-dimensional model into a scene by adopting a self-established model library and/or a dynamic self-established model; planning the sizes of the radio frequency simulation darkroom in the length direction, the width direction and the height direction; based on the length, width and height dimensions of the radio frequency simulation darkroom, calculating the position and dimension characteristics of the main reflection region according to a Fresnel formula; and generating a three-dimensional feature cloud picture of the main reflection region according to the position and size features of the main reflection region. Dynamic generation of the three-dimensional scene is realized by utilizing the self-built model library and the dynamic self-built model, the modeling speed is improved, automatic region division and performance calculation of related regions are completed based on the three-dimensional scene model, real-time automatic generation of the model is realized, and the performance calculation part is combined with the real-time dynamic model, so that the real-time dynamic generation of the model is realized. And the confidence coefficient of the calculation result is increased.

Description

technical field [0001] The invention relates to the field of radio frequency simulation, in particular to a three-dimensional scene dynamic modeling method and system for a radio frequency simulation darkroom. Background technique [0002] The radio frequency simulation darkroom belongs to the semi-physical simulation test simulation system, which has the characteristics of high investment cost and long construction period. The construction of this type of experimental simulation system should be more cautious to prevent the performance from failing to meet the expected requirements due to insufficient demonstration work in the early stage. [0003] The existing pre-demonstration process for the construction of a radio frequency simulation darkroom mainly includes structural model design, performance calculation and analysis, etc. The structural model design is mainly based on 3D modeling software, the design cycle is long, and it is impossible to automatically model accord...
