The invention relates to a monitoring point optimization method and device fusing a GIS technology and face recognition, and a terminal. According to the method, the GIS technology and the face recognition technology are adopted to realize
grid management of a monitoring area; data is provided for abnormal track line identification through equipment parameter information and
monitoring data of monitoring equipment; according to the
monitoring data and the snapshot data, a track speed and an abnormal track line are analyzed, a monitoring blind area in a monitoring area is identified, virtual
point location construction is carried out on the abnormal track line, a construction recommendation numerical value is obtained, a monitoring range map after accurate monitoring
point location construction optimization is obtained, the coverage rate and monitoring efficiency of a monitoring network are remarkably improved, and the monitoring efficiency of the monitoring network is improved. The monitoring blind area is effectively reduced, and the construction and operation cost of the
monitoring system is reduced; the technical problems that traditional monitoring
point location layout depends on artificial experience and on-site investigation, the efficiency is low, and it is difficult to ensure that a monitoring network can comprehensively cover a key area, and consequently resources are wasted are solved.
