The invention relates to a sight line analysis method and device, computer equipment and a storage medium. The sight line analysis method comprises the steps: generating a corresponding bounding box according to the space coordinates of a seat model in a work space, and determining an observation point in the bounding box; and establishing a curved surface model in the working space to serve as atarget observation area, randomly distributing a preset number of target viewpoints in the target observation area, and connecting intervisibility curves between the target viewpoints and observationpoints. Therefore, manual connection of an intervisibility curve between an observation point and a target viewpoint on a stage is avoided, and the technical problem of long consumed time of sight line analysis in the prior art is solved. The other models except the curved surface model in the working space are set as the collision models, and the sight shielding condition of the observation pointis analyzed by detecting whether the intersections exist between the intervisibility curves and the collision models or not, and the analysis process does not need to be manually intervened, and manual verification and check are avoided, and the sight analysis efficiency is improved.
