Building construction management method and system based on two-dimensional code

The embodiment of the invention relates to the technical field of building construction management, and particularly discloses a building construction management method and system based on a two-dimensional code. According to the embodiment of the invention, a plurality of construction management stages are divided through staged analysis; analyzing the stage planning data, and dividing the stage planning data into a plurality of material entering sub-stages; when the material enters the field, obtaining a field entering monitoring video, and identifying and scanning the two-dimensional code image; performing entering material identification on the entering monitoring video, and recording material identification data; and when the material is abnormal, an entry abnormal alarm is given. Material entering monitoring, two-dimensional code image recognition and scanning and current entering data matching can be performed, entering material recognition and material recognition data recording are performed on an en
