3D scene engineering simulation and real-life scene fusion system

A three-dimensional scene engineering simulation and real-life scene fusion system (3D system) comprising:

• at least one processor;
• and
• at least one memory storing a plurality of instructions, which when executed by the at least one processor, cause the processor to:
• obtain three-dimensional coordinates of each point of a three-dimensional model of a real-life scene;
• obtain engineering data corresponding to the three-dimensional coordinates of each point analyzed according to the three-dimensional model;
• acquire location information of at least one point of the real-life scene;
• establish a correspondence between the three-dimensional coordinates of each point of the three-dimensional model and the location information of the at least one point of the real-life scene according to the acquired location information of the at least one point of the real-life scene and the three-dimensional coordinates corresponding to the at least one point;
• provide a scene fusion interactive interface on a display screen of a mobile terminal;
• acquire an image of a target scene in the real-life scene in real time in response to an operation of capturing an image on the display screen;
• acquire location information and orientation information of the mobile terminal;
• determine three-dimensional coordinates corresponding to the location information of the mobile terminal in the three-dimensional model according to the correspondence relationship and the location information of the mobile terminal;
• determine a three-dimensional coordinate range corresponding to the acquired image according to the three-dimensional model, the determined three-dimensional coordinates, the orientation information, and a size of the display screen;
• and
• merge the engineering data corresponding to the three-dimensional coordinate range into the image of the target scene according to an operation of merging the scene on the display screen to form a realistic scene engineering simulation image.
