Problems solved by technology

However, since 3D display requires operations such as image matching, depth map calculation, point cloud acquisition, 3D modeling, and model rendering, the amount of calculation is huge. Although the technology is relatively mature, modeling is difficult, complex, and real-time. The authenticity is not good, and there are many limitations and deficiencies in the application, resulting in low drawing efficiency and poor real-time interactivity in the actual 3D display

Abstract

The invention discloses a three-dimensional oil flow VR online measurement and display system and a working method thereof. The system comprises a hardware system and a software system matched with the hardware system. The hardware system comprises a data acquisition subsystem, a data transmission subsystem, a test interaction display subsystem and a three-dimensional graphic workstation. The software system comprises a synchronization and data acquisition module, an oil flow calculation module, a real-time three-dimensional drawing calculation module, a three-dimensional modeling and rendering module and an interaction control and display module. The three-dimensional graphic workstation divides the display of the whole test into two stages, namely a three-dimensional real-time display stage and a three-dimensional modeling display stage. In the three-dimensional real-time display stage, a virtual viewpoint drawing technology is adopted, and the real-time performance can be met; and in the three-dimensional modeling display stage, an offline modeling mode is adopted, so that comprehensive and accurate information can be achieved, and a displayed three-dimensional target model is fine and attractive.

Description

technical field [0001] The invention relates to the technical field of oil flow test, in particular to a three-dimensional oil flow VR online measurement and display system and a working method thereof. Background technique [0002] As the most traditional and important display and measurement technology of surface friction stress in flow display, oil flow method is an important means to solve practical engineering problems. In the basic research of modern fluid mechanics and aerodynamics, the surface friction stress distribution is the best way to describe the state of the turbulent boundary layer, and it is also one of the most important physical quantities to describe the state of the turbulent boundary layer; The understanding of unsteady flow and turbulence phenomena is limited, but the solution to these problems is particularly important and urgent in engineering practical applications. Therefore, the flow field display based on the oil flow method is extremely importa...
