Closed type augmented and virtual reality system and method

The invention provides a closed type augmented and virtual reality system. The closed type augmented and virtual reality system is characterized by comprising a first processing unit (101), a fusion unit (102), a data unit (103), a display unit (104), a first switch (105), a second switch (106) and a live-action camera (107). The invention further provides a corresponding method. By means of the closed type augmented and virtual reality system and method, a real scene and a virtual scene are obtained in a control mode, the processing unit carries out corresponding processing according to the obtained conditions, and therefore integration of the augmented reality and virtual reality functions is achieved, the obtained real scene is fused into the virtual scene, and due to the closed type augmented reality, external disturbance is small, all-perspective displaying is achieved, the amount of information is large, and information is convenient to understand.
