The invention provides a method and system for measuring a downward inclination angle of a plate-shaped antenna based on mobile phone information fusion, and the system comprises a basic measurement module which is used for shooting an antenna image through a mobile phone, eliminating parameters related to the distance in a camera imaging principle, and solving the downward inclination angle of the antenna through combining IMU data and the specific model information of the antenna; the virtual holding pole module is used for shooting an image of a checkerboard of the virtual holding pole module in the gravity direction through a mobile phone, solving a gravity vector on the image and obtaining a downward inclination angle after error correction; and the image length-width ratio solving module is used for photographing from the front side of the antenna to obtain the length-width ratio of the antenna on the image when the model of the antenna is unknown, replacing the dimension ratio of the real antenna with
