A three-dimensional visual analysis method and system

Abstract

The invention provides a three-dimensional visual analysis method and system, and the method comprises the steps: receiving the three-dimensional sight point coordinates, sent by an eye movement capturing device, of each participant in a virtual reality environment in real time; And carrying out visual analysis on the three-dimensional space coordinates of the sight points of all the participants.The technical problem that in the prior art, three-dimensional space elements which cannot affect spatial cognition and the three-dimensional space positions of sight points cannot be subjected to three-dimensional space positioning is solved; the technical effect of positioning and identifying the spatial elements influencing spatial cognition and the three-dimensional spatial positions of the sight points in the three-dimensional space is achieved; The method alleviates the problem that the sight line, the sight distance and the group superposition analysis cannot be carried out on the spatial cognitive experiment data in the prior art, and achieves the technical effect that the sight line, the sight distance and the group superposition analysis of the spatial cognitive experiment datacan be carried out in the three-dimensional basic model.

Description

technical field [0001] The invention relates to the technical field of spatial cognition, in particular to a three-dimensional visualization analysis method and system. Background technique [0002] The quality and value of architectural and urban space environments are determined by people's spatial cognition and use experience. How to analyze people's cognitive mechanism and usage through technical means is one of the main problems in the study of spatial cognition. There are three difficulties in traditional research methods. First, real architectural and urban research samples are distributed all over the world, and the environment is complex, making it difficult to implement ideal experimental research. Second, it is impossible to conduct testing and evaluation for unbuilt buildings and cities. In addition, recruiting a large number of people to be tested Has a certain degree of difficulty. With the rapid development of virtual reality technology, large-scale building...

Problems solved by technology

It is difficult to capture viewpoints and analyze viewpoint distribution in three-dimensional space. Therefore, it is impossible to accurately display the spatial elements that affect spatial cognition and the spatial position of viewpoints.

[0005] (2) Obvious motion sickness in the immersive virtual reality environment: At present, immersive virtual reality experiments are mostly controlled by head-mounted displays and joysticks. There is no movement. Under the synergistic effect of the vestibular system and the visual system, when the participants move in the virtual reality environment, they will often be accompanied by reactions such as dizziness and nausea, which will have a certain impact on cognitive experiments.

[0006] (3) The authenticity of the virtual reality cognitive experiment model is poor: in the past, the virtual reality experiment of spatial cognition is to build a simple three-dimensional model, and the surface material is textured or no material

There may be some differences in the experimental results due to the large difference from the real environment
