As shown in fig. 6 and 7, the software construction process is as follows:
1) initial environmental scenario establishment
The initial environment is the first scene seen by the user wearing the virtual reality head-mounted display device, and possibly the first time the user experiences the virtual reality environment. In order to adapt to the virtual reality environment as soon as possible, it is important to weaken the gap between the virtual environment and the real environment.
2) Training hall scene establishment
The function of the training hall is set for the user to make a training scene selection function. The environment of the training hall refers to the picture information of the training center hall to carry out three-dimensional reconstruction, so that functionally, on one hand, a user is continuously transited to a relatively familiar scene, and on the other hand, discomfort caused by sudden conversion from a small space to an outdoor open space is avoided.
3) Radiation field scene creation
The method comprises the steps of obtaining visual data configuration virtual scenes of the radiation field from a random forest algorithm, selecting a target plant area and a region, loading an elevation map of the corresponding region through a Unity3D, leveling the ground by using a terrain system of Unity3D, importing models such as virtual plants, facility equipment and the like which are manufactured by 3DsMax modeling, and importing the models to finish building of an environment model of the radiation field.
4) Interactive interface design
Design of guiding interface
And designing a use flow according to the initial environment interaction, and dividing the interface into an initial interface, an introduction interface, a holder laser/level function cognition prompt interface, a holder function key cognition prompt interface, a holder trigger key cognition prompt interface, a virtual space cognition prompt interface, a new hand course quitting prompt interface and a warning interface.
Training hall interface design
Through the analysis of the functions of the training hall, the training hall mainly completes four parts, namely selection of decontamination equipment, selection of decontamination rooms, setting of a simulated environment and starting of a training button. We separate the user interface usage distance into three main sections, the left selecting functions for the decontamination apparatus. In order to enable a user to select a decontamination device to be used more intuitively, a silhouette model of the decontamination device is combined with a scene photo and text description of the decontamination device to assist the user in selecting. The right side is a scene specific environment setting function, and if special training of a high and medium radioactive room is required, parameters such as operation time, a radiation dose absorption warning value and the like are required to be set. The upper side of the middle column is provided with a plurality of selectable room types, and a user can select different training subjects, press a training starting button at the lower part of the middle part after selecting the training subjects and start decontamination training.
Thirdly, design of decontamination operation room interface
The interactive interface functions of the decontamination operation room mainly comprise: displaying a radiation value interface; displaying the decontamination time; the decontamination effect is displayed; a radiation absorbed dose cue; the level turns off and on function; return to the training lobby function and exit from the training function. Through analyzing and combing the functions, the main interactive interface function of the decontamination operation room is roughly divided into two parts, one part is the function needing to be paid attention to at any time and comprises radiation value interface display; displaying the decontamination time; the decontamination effect is displayed; radiation absorbed dose cues. The other part is an interface and a key for stage observation and use, and comprises score analysis interface display; the level turns off and on function; return to the training lobby function and exit from the training function.
5) Holder design and implementation
The holder is divided into two parts, namely a holder body, a trigger key and a function key state receiving part. The holder body has two functions, namely a trigger and a function key module, and a gun body state sensing module.
The holder positioning equipment is realized by adopting a TRACKER module in an HTCVIVE virtual reality set, and the general principle is that 24 photoelectric sensors on the module receive infrared rays emitted by the HTCVIVE virtual reality set positioning equipment, the information such as the position of the TRACKER module is judged according to the difference of the received infrared ray intensity and the gyroscope shape , and a virtual TRACKER model is generated at the same position of the virtual world. And because the holder is rigidly connected with the TRACKER module, the position of the virtual decontamination equipment model is generated according to the position information of the TRACKER module. The trigger and the function key module are realized by adopting an encapsulated external mini HID keyboard module with a wireless device because wireless control is required to be realized. In addition, a battery module and a state display LED diode are arranged.
