Abstract: In order to improve the psychological quality of emergency rescue personnel, the psychological adaptability training contents under the conditions of high altitude, fire, earthquake and other scenes are set up, and the overall design of the system is analyzed from the perspective of the overall structure, functional modules and implementation process design of the system. At the same time, taking the high altitude psychological adaptability training course as an object, the process of system development and implementation using unity, Revit 2020 and other technologies is described from the aspects of development environment selection, scene design and introduction, key technology implementation, training assessment, system release, etc. This training method can effectively make up for the shortage of psychological training for emergency rescue personnel, and also provide a reference for the further application of VR technology in the field of emergency rescue training.
