Zusammenfassung:This application disclose a feature extraction method performed by a computer device. The method includes: shooting a cone-shaped group of viewing-frustum rays from a target character object for a hit object in a three-dimensional scene picture; determining object attribute information of the hit object based on an interaction between the viewing-frustum rays and the hit object; performing vector conversion on the object attribute information of the hit object, to obtain a ray-feature vector; collecting, by using a location of the target character object as a collection center, a plurality of height-value matrices corresponding to different granularities; performing feature dimension reduction on the height-value matrix corresponding to each granularity, to obtain a height-map feature vector; and integrating the ray-feature vector and the height-map feature vector into a three-dimensional scene feature.
