Elevator scene recognition method and device, electronic equipment and storage medium

Abstract

The invention provides an elevator scene recognition method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring video clips obtained by segmenting a video stream according to a preset time length, inputting the video clips into an elevator scene recognition model, and performing feature extraction on the video clips by using an action recognition deep network; using a first feature extraction channel to extract the spatial dimension features to obtain a first feature map, using a second feature extraction channel to extract the time dimension features to obtain a second feature map, and using a third feature extraction channel to fuse the spatial dimension features and the time dimension features to obtain a third feature map; and performing global average pooling and feature splicing on the first feature map, the second feature map and the third feature map, predicting the feature map obtained after feature splicing, and determining an elevator scene corresponding to the video clip according to a prediction result. The elevator scene can be accurately recognized, and full-scene recognition and monitoring of the elevator are achieved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an elevator scene recognition method, device, electronic equipment and storage medium. Background technique [0002] With the development of computer technology and multimedia technology, the use of video for scene monitoring is more and more widely used. For example, by monitoring the scene in the elevator, abnormal situations can be found and responded in time. [0003] In the prior art, using a traditional video monitoring system requires manual real-time monitoring of the monitoring video, which is prone to misjudgment and missed judgment. Although some artificial intelligence algorithms based on computer vision can recognize behaviors in videos, in the process of elevator scene recognition, due to the high information complexity and intra-class diversity of the elevator scene and passenger actions that need to be recognized and inter-class similarity, which p...
