With the increasing complexity of construction project management, more and more automatic and intelligent construction schedule management methods are concerned by the traditional management field. However, the existing mainstream methods are limited by high cost and complex use, which are difficult to apply to complex construction schedule management scenarios. By comparing the characteristics of various kinds of 3D reconstruction technology, this study built a collaborative management system of construction schedule based on deep learning 3D Reconstruction Technology (DLR-P). By collecting the real-time image information of the construction site, the system completes the reconstruction from two-dimensional information to three-dimensional information, and realizes the automatic control of the construction progress combined with BIM dynamic model technology. In view of the system, this study conducted a case study in the construction site of a project in Banan District of Chongqing, and analyzed the data in the process of system operation. The results show that the average 3D reconstruction time of construction schedule collaborative management system (DLR-P) based on deep learning 3D reconstruction technology is 61 seconds, which can meet the basic schedule management requirements, realize the automatic management of construction schedule, and effectively improve the efficiency of construction schedule management. Compared with the existing management mode, it has great advantages in the operation cost and convenience.
