The three-dimensional virtual reality technology was introduced into the visualized substation. The virtual substation models of main electrical equipment and the whole scene were built by using 3dsMax modeling software. After the design of special events response routing and editting the corresponding script language, users can interact with virtual objects in the scene model, resulting in feelings and experiences on the ground. Compared with the real substation, the virtual substation has the advantages of low cost, interactive operation safety, and is of great significance to improve the technical level of the operators.

The existing optimization methods have the problem of image edge blur, which leads to a high degree of shadow residue. In order to address this problem, reduce the shadow residual degree, this paper designs a 3D video image processing effect optimization method supported by virtual reality technology. Coding was used to eliminate redundant data in video and eliminate image noise using median filtering. The virtual reality technology detects the image edge and determines the motion offset between the image frames. According to the motion parameters of the camera carrier obtained from the motion estimation, the feature point matching algorithm constructs the video image motion model, and uses the camera calibration technology to set the processing effect optimization mode. It is optimized by perspective projection transformation. Experimental results: the average shadow residual degree of the optimization method and the two existing optimization methods are 3.108%, 6.167% and 6.396% respectively, which proves that the optimization method combined with virtual reality technology has higher practical application value.

AbstractBackgroundThe current coronavirus disease 2019 pandemic has caused unprecedented challenges to surgical training across the world. With the widespread cancellations of clinical and academic activities, educators are looking to technological advancements to help ‘bridge the gap’ and continue medical education.SolutionsSimulation-based training as the ‘gold standard’ for medical education has limitations that prevent widespread adoption outside suitably resourced centres. Virtual reality has the potential to surmount these barriers, whilst fulfilling the fundamental aim of simulation-based training to provide a safe, effective and realistic learning environment.Current limitations and insights for futureThe main limitations of virtual reality technology include comfort and the restrictive power of mobile processors. There exists a clear developmental path to address these restrictions. Continued developments of the hardware and software set to deepen immersion and widen the possibilities within surgical education.ConclusionIn the post coronavirus disease 2019 educational landscape, virtual, augmented and mixed reality technology may prove invaluable in the training of the next generation of surgeons.
