The invention discloses a viewing screen judgment method and system and electronic equipment. The viewing screen judgment method comprises the following steps: an acquisition step: acquiring image data through a camera; a face data obtaining step: obtaining face data in the image data through a face detection algorithm according to the image data; a key point information acquisition step of acquiring key point information of the face data through a face key point detection algorithm according to the face data; a face orientation obtaining step: obtaining an Euler angle of the face data througha PnP algorithm according to the key point information and a standard face template, and obtaining a face orientation of the face data according to the Euler angle; and a judgment step: judging whether the user watches the screen or not according to the face orientation and the horizontal distance from the face to the screen. According to the invention, in a scene that only a common RGB camera issmall in space, whether a
