The present invention relates to a subdivision stream type loading method of equipment high density scenes. The method is characterized by comprising the following steps of 1) splitting the high density scene pictures to obtain a plurality of subdivision high density scene pictures, and naming the all subdivision high density scene pictures orderly; 2) establishing a subdivision picture model according to the subdivision high density scene pictures, and establishing an index catalog at a server terminal according to the subdivision picture model and the names; 3) adopting a set partitioning in hierarchical trees algorithm to transform the subdivision picture model into a plurality of progressive code streams; 4) after the communication between a client and the server terminal is established, according to the request scene range information of a user at the client and the data of the progressive code streams, feeding back the corresponding index catalog to the client; 5) using the client to mount the received index catalog to a local catalog according to a network file protocol, and obtaining the high density scene data according to the demands of the user. Compared with the prior art, the subdivision stream type loading method of the equipment high density scenes of the present invention has the advantages of high precision, good practicality, etc.
