The invention relates to a projector network intelligent upgrading module and control platform system. The projector network intelligent upgrading module and control platform system comprises a PROCAMS (projector-camera system), a synchronization control bus and a control platform system. The PROCAMS comprises a projector, a digital camera, an FPGA and an embedded machine. Multiple PROCAMSs are connected through a control bus to form a projector network intelligent upgrading module. A control platform is cross platform software, can run on a PC or a tablet computer, and controls and coordinates each PROCAMS through the control bus. The main research content of the system comprises "a PROCAMS self-calibrating technology", "a multi-PROCAMS automatic stacking enhancement technology", "a multi-projection multi-camera free curved surface splicing fusion correction technology", "multi-PROCAMS control platform software development" and "a multi-projection display phase synchronization technology". According to the system provided by the invention, conventional low-level projectors with excessive production power are upgraded to high-quality extensible PROCAMS equipment, a high-end engineering projector can be replaced on many occasions, new applications can also be developed, and its application can promote upgrading, innovation and development of the projection product industry.
