Abstract

The present application relates to the field of artificial intelligence, and discloses a depth map completion method and apparatus, a computer device, and a storage medium. The method comprises: aggregating features of a scene image and a sparse depth map to obtain an aggregated feature, wherein the sparse depth map is a depth map having missing depth information corresponding to the scene image, and the aggregated feature is subjected to a noise addition process; on the basis of a diffusion strength parameter, diffusing and completing the aggregated feature by means of a depth completion network to obtain a depth completion feature, wherein the depth completion network is based on a diffusion model, and the diffusion strength parameter is used for controlling reverse diffusion strength in a depth completion process; and performing image restoration on the basis of the depth completion feature to obtain a dense depth map, wherein the depth information completeness of the dense depth map is higher than the depth information completeness of the sparse depth map. The method provided by the embodiments of the present application can reduce the risk of overfitting of a model in the training process, and improves the robustness of a depth completion network in a reasoning stage.
