Method, device and equipment for constructing entity model in virtual reality environment

Abstract

The invention discloses a method, a device and equipment for constructing an entity model in a virtual reality environment. The method comprises the steps of: acquiring a connection relationship amonga plurality of key position points on an entity to be tested which is placed in an optical motion capturing environment; acquiring position information of a standard measurement object with a plurality of reflective marking points in a preset coordinate system, wherein the standard measurement object is placed at one key position point; calculating to generate coordinate data of the key positionpoint according to the position information; and generating a three-dimensional digital model of the entity to be tested according to the coordinate data and the connection relationship. By adopting the method, the device and the equipment, a mode of pre-establishing the optical motion capturing environment is adopted, an optical motion capturing measurement tool is adopted and a marking means ofrecording the key position points quickly and accurately is employed for manufacturing a three-dimensional data model of the entity structure efficiently and precisely, and the time consumption is farless than that of the traditional physical measurement methods.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a method, device and equipment for constructing a solid model in a virtual reality environment. Background technique [0002] In the virtual reality environment, in the instance that needs to be combined with the user's sense of touch, it is necessary to build a specific architectural structure environment, and make a digital model of a three-dimensional structure that is exactly the same as the architectural structure in the virtual reality environment, and make it consistent with the virtual reality environment. The location of the structure in . [0003] Generally speaking, the establishment of a virtual reality 3D model needs to refer to the reference data provided by the architectural plan and related drawings. Due to the construction accuracy of the construction project and various restrictions on the site environment, there will always be inevitable problems in the specific ...

[0003] Generally speaking, the establishment of a virtual reality 3D model needs to refer to the reference data provided by the architectural plan and related drawings. Due to the construction accuracy of the construction project and various restrictions on the site environment, there will always be inevitable problems in the specific architectural structure environment and design. Even if this data difference meets the accuracy requirements of engineering buildings, in a virtual reality environment that requires users to directly perform physical contact and visual measurement, it will still be unable to fully match the 3D model, which may cause users to experience visual and actual differences. The error of the distance may cause bumps, bumps or accidental touches

[0004] Generally speaking, in order to calibrate this deviation, in the existing scheme, the staff is usually required to wear a virtual reality head display, enter the construction environment, and measure the data deviation of each individual building unit by touching or using measurement tools. Calibration, in a slightly larger building environment, this calibration work needs to be repeated, the workload increases with the size and complexity of the building structure, and it takes a long time to be accurate, especially for non-standard buildings, such as slopes (Not at right angles to each other), the difficulty increases with curved and curved surfaces and other irregular shapes, often time-consuming but not ideal results
