Research On The Virtual Environment For The Safety Operation Of Oil-field And The Interactive Technology

As the rapid development of computer technology, virtual reality technology exists in all areas of human life. People are no longer satisfied with only roam in a virtual environment, but are eager to further interaction with the environment. With the increasing difficulty of mining of oil-field, security problems have become increasingly prominent; operators need to be trained for oil-field safety operation urgently. The virtual reality technology was used to construct a simulation system for training of oil-field safety production, and the virtual characters were added to the virtual environment that as the avatar of an operator during their operation. Therefore, virtual characters and virtual interactive objects become very important. in real life the easy interaction there is likely to became very complex in a virtual environment, because sufficient information need to be given to the virtual characters for the interaction.The virtual environment and interactive technology was introduced in this paper as well as their development situation at home and abroad. A development framework was propose for the safety operation of oil-field virtual environment. The framework was composed by four phases; they are geometric modeling, behavioral modeling, integration and scenes driving and implementation method of each phase was studied. Feature modeling was used to solve virtual characters and objects behavioral modeling, interactive information was stored in the description of objects. This method reduces the compute time and improves the speed of the system. At the same time, the operate task is divided through the method of delaminating and subsection to the characteristics of oil-field safety operation simulation system, a set of universal basic motions are summed up and a basic motion database is established. The virtual human's behaviors are planed using the basic motion. As the Smart objects and the basic motion database can reusable, the speed of the development about simulation for training of oil-fields safety task operation is greatly increased. Finally, the development technology of virtual environment and interactive technology were applied to the safety operation of oil-fields, and good result was obtained. Practical application shows that the method proposed in this paper has a certain practical value and reference value.
