Road image anomaly detection method and device, electronic device and storage medium

The invention provides a road image anomaly detection method and detection device based on unmanned aerial vehicle shooting, an electronic device and a storage medium. The road image anomaly detection method comprises the steps of obtaining an initial feature library S < initial > of a target road; obtaining and carrying out object detection on the plurality of first images, the detection objects including motor vehicles, non-motor vehicles and pedestrians; extracting a first feature library S1 of the target road according to the plurality of first images, and comparing the first feature library S1 with the initial feature library S to obtain an abnormal probability P1; the detection objects in the step S200 are excluded, and a second image set H2 is generated; and carrying out abnormal region extraction on the second image set H2, comparing an abnormal region with a threshold value C, and outputting an abnormal result. According to the invention, the technical problems of repetitive work and time and labor w
