Description

Technical Field

[0001] The present invention belongs to the field of construction technology (the entire life cycle of BIM engineering construction), and in particular relates to a BIM engineering solution display method and system that integrates multiple display modes and customized paths. Background Art

[0002] In the railway survey and design industry, from bidding, planning and design, construction to delivery and acceptance, each link needs to present and report the BIM (Building Information Modeling) plan or results. The two most commonly used methods are PPT and animated video. PPT is often assisted by text and two-dimensional static pictures. The text and pictures intelligently display a certain angle of the scene, and even a wide-angle lens cannot fully display the scene; its defect is that it cannot intuitively display the relative position of the three-dimensional space and lacks three-dimensional dynamic effects. Although animated videos can present three-dimensional effects, they have the defects of being unable to realize human-computer interaction in three-dimensional scenes, viewing is not free, and unable to zoom in on parts. Therefore, it is necessary to propose a new BIM engineering plan display method that integrates two-dimensional, three-dimensional, and video.

[0003] Integrate 2D text, pictures, videos and other media into 3D BIM scenes, package BIM solution results by customizing display routes, display methods and display effects, and finally present users with an immersive and technological report, so that design solutions or results are easier to be recognized. It solves the problem of how to make BIM solution report more accurate, easier to understand and accept, more technological and more exciting in a short time. In addition, the time and content of general reports are limited, and the effect of the report directly affects the listeners' evaluation of BIM solutions and results. How to leave a deep impression on users in a short time can not only make the report more colorful, but also use advanced technical means to give leaders and experts (listeners) a psychological and visual sense of novelty.

[0004] Traditional PPT presentations are mostly assisted by text and two-dimensional drawings, using two-dimensional methods to express three-dimensional principles and effects, but the problems and defects are:

[0005] (1) It is difficult to clearly and intuitively express the intertwined relationship of three-dimensional space in two dimensions; (2) The intertwined relationship of multiple schemes in three-dimensional space is not clearly and intuitively expressed; (3) For non-industry or non-professionals, the drawings are difficult to read and understand, and it is difficult for listeners to understand the design scheme in a short period of time; (4) The BIM design effect can only be imagined in three dimensions, and it is impossible to truly immerse yourself in and intuitively view the design effect; (5) It is impossible to interactively customize the local details of the design effect.

[0006] Traditional video presentation methods mostly use animated video streams to present solution results. Although they are intuitive and clear, they still have the following disadvantages:

[0007] (1) Listeners cannot customize their viewing of any detail space; (2) Listeners cannot adjust the playback time of the video stream; (3) Listeners cannot zoom in and out of a specific part; (4) Listeners cannot customize the 3D display route; (5) Listeners cannot mark key points in the 3D scene.

[0008] The difficulty of solving the above problems and defects is: since each method has its own technical characteristics, directly solving the defects of each method is not enough to solve the problem. Therefore, consider integrating two-dimensional pictures and videos into the BIM three-dimensional scene, and then combining the advantages of each method through technical means to achieve better results.

[0009] The significance of solving the above problems and defects is that this method solves the problems in the traditional BIM scheme or results reporting process, which only rely on two dimensions and cannot intuitively display the relative position of three-dimensional space, cannot realize human-computer interaction in three-dimensional scenes, lacks three-dimensional dynamic effects, and cannot customize the viewing of any space of the scheme, cannot mark key points, and the report display is not free. It can integrate two-dimensional pictures and animated videos into three-dimensional BIM scenes; can customize the report display route, including route editing management and route point management; can set the report display effect, including point dwell time, display method, and local display effect. It achieves the purpose of integrating the advantages of various single display methods into one, and effectively enhances the effect of report display. Summary of the invention

Then follow the steps below:

[0161] (1) Create a report presentation route, enter the route name (such as the central waiting hall B1 exit floor lobby plan report route) and route code to form a basic report presentation route.

[0162] (2) By interactively roaming in the scene, route points are added to the report display route.

For example, add an inward route point to the exit A of the central waiting hall to facilitate viewing the internal structure of the hall from the exit. After the adjustment is completed, the final report display route is formed.
