Description

Red education platform based on VR technique

Technical Field

The invention relates to the field of VR (virtual reality), in particular to a red education platform based on VR technology.

Background

The red education is education by taking red as a symbolic and pragmatic place of the spirit connotation of the times. The call has the advantages of youth, national worry, self challenge, exceeding self challenge, extreme challenge and contribution to the high spirit of society. Meanwhile, the old area of revolution also needs to advance with time, and the spanning type large development is realized. Countless red army warriors are dedicated in the year so that the revolutionary and old areas of the army and the marshal are emerging with new generation of wind and cloud characters and are calling more and more deficient talents in various aspects. The red education is to educate the next generation with the red soil, build the red soil by nursing talents, nourish green life on the red soil stained by the fresh blood of the knight, and realize the sustainable development of the revolutionary old area and people.

Red education has broad and narrow meanings. The broad red education is that the educated person is subjected to certain emotional fumigation and motivation activities on the subject of all advanced character trails at home and abroad or a great spirit and a carrier thereof. The red education in the narrow sense means that the education subject purposefully, planningly and organically develops the activities which arouse and motivate the educated people by utilizing the great spirit and the vector thereof formed by Communist Party of China leading people of various groups in China in the revolution and construction practice.

The memorial hall is used as a memorial place which is established for commemorating people with excellent contribution or important historical events, and represents the spirit of the events by various aspects such as sound, light, electricity, pictures, objects and the like. The tourist provides a place for memorial great visitors to struggle and achieve great profits, and the historical fact is used for reminding the great visitors of not forgetting the pubic state and the beginnings. Therefore, the recorded historical events in the memorial hall are used for promoting the red cultural education, the historical events can be restored more vividly, and people can be more cherished the fortunes.

In the prior art, most of historical events displayed in a memorial hall are characters, videos and the like and are presented to tourists, and the tourists know the history through played videos, recorded pictures, characters and the like. However, the tourists only know the history visually and aurally but cannot well integrate into the history event, so that the environment of the historical characters at that time is not easy to be known, and the feeling of the tourists is not particularly deep, so that a virtual historical environment is required to be provided for the tourists, and the tourists can know the history more deeply.
