Abstract: Disclosed is a method, device and system for determining stereoscopic multimedia information. The method includes: acquiring multimedia information collected by respective multimedia collection apparatuses of two or more aerial vehicles; and, determining corresponding stereoscopic multimedia information according to the acquired multimedia information. In the present disclosure, a same object is shot by respective loaded multimedia collection apparatuses of two or more aerial vehicles at different angles. In comparison with conventionally shooting a same object by a single unmanned aerial vehicle at a same angle, more stereoscopic multimedia information may be obtained, and a user is more likely to feel the stereoscopic impression of the multimedia information when viewing the multimedia information. In this way, both the visual enjoyment of the user and the user experience are improved.
