Problems solved by technology

However, in terms of virtual street view experience, the current research focuses on the interior of the building, and the outdoor model of the building is rough and lacks realism (Jia Qiang. The application of virtual reality technology in real estate development [J]. Value Engineering, 2016, (16): 199- 200), affecting the performance of the Street View experience

Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The invention provides a room street view pricing method based on oblique photography and a building information model.

[0035] The main flow chart of the method is as follows figure 1 It mainly includes: (1) Realistic 3D environment modeling based on oblique photogrammetry; (2) VR scene creation based on BIM and oblique photogrammetry; (3) WTP evaluation of room street view. The specific process is as follows:

[0036] (1) Realistic 3D environment modeling based on oblique photogrammetry:

[0037] The oblique photographic modeling software uses ContextCapture, which is widely used in the market, to build a 3D environment model. The general modeling process of this software is as follows: figure 2 shown. The process mainly consists of two st...

Abstract

The invention provides a room streetscape pricing method based on oblique photography and a building information model (BIM) and belongs to the field of construction engineering technology. Accordingto the method, first, BIM software is utilized to establish a fine model of a target building, and an oblique photography measurement technology is utilized to establish a surrounding environmental model of the target building; second, the BIM and an oblique photography measurement model are subjected to model space matching, and a virtual reality scene capable of being experienced is formed; andlast, a room streetscape willingness-to-pay evaluation method based on virtual experience is proposed. Taking a six-floor residential building as an example, a room streetscape virtual experience andpricing process is displayed, and the usability of the method is proved. The method provides a new technical means for pricing of a room streetscape at a pre-sale stage in a real estate project.

Description

technical field [0001] The invention relates to the technical field of architectural engineering, in particular to a room street view pricing method based on oblique photography and building information models. Background technique [0002] In real estate projects, the quality of the street view of the room affects the pricing of the room to a certain extent. In the pre-sale stage, the house has not been built, and the street view of the room cannot be experienced, which brings difficulties to the pricing of houses with different street views. [0003] In the traditional real estate pre-sale stage, real estate developers often use sand table and architectural renderings, etc., but these technologies have certain limitations. The sand table model can only obtain a bird's-eye view image, and the architectural renderings can only Can provide a static visual experience. [0004] Through virtual reality VR technology, if users can experience the street view of the room in advan...
