We understand virtual stages as dynamic three-dimensional simulations aimed at 3D environment viewing. These scenarios will form the basis for later three-dimensional reconstruction of large movie or TV stages where the aim is to have a foundation that simulates the reality in order to create huge fictitious structures.
Technology used and main advantages
The technology used to obtain virtual stages varies greatly. The main purpose is to obtain textured triangular meshes from large cloud points of the reality, meaning the technologies or methods for obtaining them range from Mobile Mapping, terrestrial laser scanning, survey pack, drones, etc.
Mobile Mapping is the ideal technology for data acquisition over large surface areas. Whenever there are areas where this technology cannot be used, either because the roads are pedestrian only or too narrow, this technology is implemented alongside traditional technologies such as total station or GPS, as well as faster and more modern ones like terrestrial laser scanning and survey pack.
Laser scanning is used for points of interest to obtain highly precise cloud points as it is small and compact and can work in difficult-to-access areas. We obtain cloud points and 3D meshes with real colour as the equipment we use has a built-in RGB sensor.
Survey pack makes it possible to obtain cloud points indoors and in narrow areas; it’s the best solution for linear paths needing less precision.
Drones or unmanned aerial vehicles. Whenever the elements subject of study are in areas where the law allows inspection flights, this is the best solution for obtaining Digital Terrain Models and/or rooftops or high-altitude areas as no other equipment can get there to record the data.
