Method for generating panorama in three-dimensional scene based on UE4 and displaying panorama on mobile terminal

The invention discloses a method for generating a panorama in a three-dimensional scene based on UE4 and displaying the panorama on a mobile terminal, and relates to the technical field of three-dimensional panorama display. The method comprises the following steps: S1, obtaining the world coordinate position of a virtual character in a three-dimensional scene; S2, initializing parameters of a panoramic image Actor generated by a three-dimensional scene; S3, generating a panorama picture in the three-dimensional scene; S4, creating an HttpRequest request, and uploading the panorama picture data UpFileRawData to a cloud server according to a POST mode; S5, using Krpano analysis to generate panorama material resources in the cloud server, the analyzed panorama supporting VR roaming; S6, generating a two-dimensional code picture, storing the two-dimensional code picture to the cloud, and returning a two-dimensional code picture path to a UE4 client; S7, acquiring a returned two-dimensional code picture path by t
