Abstract: A light projection apparatus includes an information obtaining module, a processing module, and a projection module. The information obtaining module is configured to obtain environment information and status information of a first object. The processing module is configured to determine, based on the status information, that the first object is a potentially dangerous object; determine a potentially dangerous area of the first object; determine a to-be-projected area based on the potentially dangerous area and the environment information, where the to-be-projected area is an area in which there is no light projection and light projection is allowed; and determine whether the to-be-projected area is within a projection range of the projection module. In response to a first result determined by the processing module, the projection module performs light projection in the to-be-projected area, to prompt a potential danger caused by the first object.
