Visual probability determination method and device, computer equipment and storage medium

The invention relates to a visual probability determination method and device, computer equipment, a storage medium and a computer program product. The method can be applied to various scenes such as cloud technology, artificial intelligence, intelligent traffic and auxiliary driving. The method comprises the following steps: in the presence of a shielding object which affects a satellite to position a to-be-positioned object, scaling the shielding object based on object parameters of the shielding object to obtain error modeling data; according to the object parameters and the error modeling data, constructing a shielding object fuzzy region including the external contour of the shielding object; based on a linear signal propagation path between the satellite position of the satellite and the candidate position of the to-be-positioned object, determining an intersection relation between the linear signal propagation path and the obscuring object fuzzy region; according to the intersection relation, the visua
