Helmet wearing detection method and device, camera, and server

The present invention relates to a helmet wearing detection method and device, a camera, and a server. The method comprises: obtaining a scene video image, detecting the scene video image to obtain human position through a human position detection model built by training learning, and determining whether the human position is located in a helmet wearing area or not; if the human position is located in the helmet wearing area, detecting the scene video image to obtain the human head helmet combination state through a human helmet combination detection model built by training learning, and determining whether the helmet is worn or not according to the human helmet combination state, if the helmet is not worn, not passing through the wearing verification of the helmet and if the helmet is worn, detecting the scene video image to obtain the type of the helmet through the helmet type detection model built by training learning, determining if the type of the helmet accords with the rule or not, if the type of the helmet accords with the rule, passing through the wearing verification of the helmet, or else, not passing through the wearing verification of the helmet, and therefore, the accuracy of the detection result of the helmet wearing is improved.
