[0025] For ease of understanding, the following embodiments use a scaffolding safety training device based on virtual reality technology as the execution subject to illustrate the scaffolding safety training method based on virtual reality technology provided by the present invention. The scaffolding safety training device based on virtual reality technology includes smart glasses, a handheld controller, a motion capture device, a host and a software system, etc. By establishing intuitive virtual construction scenes such as scaffolding safety-related training, assessment, and accidents, the training of safety content related to the erection and dismantling of scaffolding in construction projects with high site requirements and cost requirements is completed, so that trainees can learn safety knowledge such as scaffolding erection, inspection, and dismantling in a virtual environment, improve the ability to detect safety hazards, thereby avoiding construction safety risks and reducing training costs.

[0026] In the embodiment of the present invention, users can obtain a strong sense of immersion and a more realistic and rich experience in the virtual environment of a nuclear power building through a virtual reality helmet display or a wearable human-computer interaction device, thereby greatly enhancing the trainees' sense of presence and achieving the same training effect as actual installation training.

[0027] In the embodiment of the present invention, computers and sensors can be used as training equipment to miniaturize the training system. No real venue is required for training, and multiple people can train repeatedly in a virtual scene, with low system operation and maintenance costs. Since virtual reality technology uses digital technology, it can simulate the collapse scene during scaffolding construction, and there will be no casualties when trainees undergo simulated training, and no environmental pollution will be generated.

[0028] In the embodiment of the present invention, a variety of scaffolding construction models and surrounding supporting construction site environment models are constructed through three-dimensional modeling technology, so that users can experience learning in person as if they were on the scene, thereby enhancing the user's sense of involvement and reality.

Specifically, in a virtual environment, a 3D multi-scene scaffolding construction site is produced. Students build scaffolding independently according to different situations on site. The system will record the student's operation errors. If there are too many operation errors, the built part will collapse and it will be judged as an operation failure. The corresponding score will be deducted, and the construction progress will not increase. If the total score of the construction is lower than the set value, the construction is judged to be a failure and re-learning is required.

[0031] The scaffolding safety training method based on virtual reality technology provided by the embodiment of the present invention builds a scaffolding three-dimensional model in response to the scaffolding operation instruction input by the user through the VR handle device, wherein the scaffolding operation instruction is an operation instruction for instructing the scaffolding construction; if the scaffolding operation instruction is an erroneous operation, the operation score corresponding to the scaffolding operation instruction is subtracted from the total score to obtain the current construction total score; if the current construction total score is less than a preset threshold, it is determined that the scaffolding construction has failed, and the scaffolding three-dimensional model is controlled to collapse. This solution applies virtual reality technology to VR safety training for building scaffolds, reduces the safety risks of scaffolding training, enhances the real experience of trainees, and reduces the cost of safety training.

[0032] In an optional embodiment, the scaffolding safety training method based on virtual reality technology further includes: When a video viewing operation instruction input by a user is received, the corresponding scaffolding-related video is played, and the video viewing operation instruction is an operation instruction for instructing to watch a specified video.

The spatial sense and physical collision algorithm properties of virtual reality technology are used to truly restore the feeling of weightlessness and dizziness caused by falling from a high altitude. After experiencing this, students will have a higher sense of safety.

[0042] In one embodiment, 3D modeling software (such as Blender, Maya) is used to create a realistic high-altitude environment, and the realism of the environment is enhanced through fine textures and dynamic lighting effects, and environmental effects such as clouds and wind are added to increase the sense of immersion; a physics engine (such as Unity Physics, PhysX) is used to achieve accurate collision detection and response, simulate the rigid body dynamics of objects, and ensure that the movement of objects in the air and on the ground complies with the laws of physics; a physics engine is used to simulate free fall motion, ensure that the changes in acceleration and velocity comply with the acceleration of gravity, and consider the influence of air resistance to make the motion more realistic.

[0044] In one embodiment, environmental sound effects such as wind and whistling are added to enhance the sense of immersion; 3D spatial audio technology is used to match the sound source with the position in the virtual environment.

[0045] In some embodiments, the feeling of weightlessness is simulated by precisely controlling the acceleration changes of the virtual camera; during the free fall, the details of the ground and other objects are gradually reduced to simulate visual defocus and blur.

[0046] In some embodiments, flickering or rapidly changing visual effects are added during the falling process to simulate dizziness; motion blur effects are added to make the vision more unstable; and the virtual camera is slightly shaken to simulate involuntary head movements.

[0047] In the embodiment of the present invention, adjusting audio parameters according to the user's head position may include but is not limited to adjusting volume, audio source position and direction.

[0048] The scaffolding safety training method based on virtual reality technology provided by the embodiment of the present invention uses the spatial sense and physical collision algorithm properties of virtual reality technology to truly restore the feeling of weightlessness and dizziness caused by falling from a high altitude, so that users can intuitively experience safety accidents and increase safety awareness.
