Image occlusion detection method and vehicle-mounted terminal

The embodiment of the invention discloses an image occlusion detection method and a vehicle-mounted terminal. The method comprises the following steps: collecting a to-be-detected image collected by avehicle-mounted camera configured with a prime lens; extracting a feature map of the to-be-detected image through a feature extraction layer in the occlusion detection model; determining an occlusionarea in the to-be-detected image based on the feature map through an image segmentation layer in the occlusion detection model; determining a shielding result of the to-be-detected image according tothe shielding area; wherein the occlusion detection model enables the to-be-detected image to be associated with an occlusion area therein; wherein the occlusion detection model is obtained by adopting a deep learning algorithm for pre-training according to a plurality of collected sample images; wherein the sample image is an image collected by a vehicle-mounted camera configured with a prime lens, and the sample image co
