The invention discloses an oblique photography-based sensitive point influence degree analytical method. According to the method, an image capturing unit, a position tracking unit, an attitude companion module, a data guiding unit, a data receiving module, a three-dimensional analysis module, a data recording unit, an information importing module, a key data analysis module and a human-machine interaction interface are adopted; the image capturing unit, the position tracking unit and the attitude companion module transmit information to the three-dimensional analysis module through the data guiding unit; the three-dimensional analysis module is connected with the data recording unit and the key data analysis module; and the key data analysis module is connected with the information importing module. According to the oblique photography-based sensitive point influence degree analytical method of the invention, the oblique photography technology is adopted to establish a true and accurate terrain and landform model; an explosion coverage range is analyzed and predicted according to the model; and therefore, staff can be facilitated to perform targeted protection according to an explosion influence area, protection costs and protection efficiency are greatly reduced, time consumed by unnecessary protection is decreased, and high security and reliability can be realized.
