Grid-type demarcation method based on video monitoring early-warning area of mobile phone client

A grid-type demarcation method based on a video monitoring early-warning area of a mobile phone client belongs to the technical field of video monitoring. The method comprises the following steps that step 1, the mobile phone client acquires a monitoring image of the monitoring area from a monitoring terminal; step 2, the mobile phone client establishes M*N cells by adopting the monitoring image as a background; step 3, the mobile client acquires a current early-warning level of each cell from the monitoring terminal; step 4, the mobile phone client colors each cell according to the early-warning levels of the cells; step 5, a user adjusts the early-warning levels of the cells through the mobile phone client and feeds the early-warning levels back to the monitoring terminal; and step 6, the monitoring terminal generates an early-warning image according to the early-warning level of each cell of the monitoring image. According to the early-warning area demarcation method, the monitoring area is divided into th
