Problems solved by technology

If the abnormal movement on the escalator cannot be detected in time, and the operation of the escalator can be stopped in time, it may cause heavy losses to the life and property safety of the pedestrians on the escalator
[0003] The detection scheme in the related art is usually based on infrared induction to realize the start and stop operation of the elevator, which is prone to misidentification, cannot timely alarm the abnormal behavior, and the detection effect is poor

Abstract

The invention relates to an event detection method and device, electronic equipment and a storage medium. The method comprises the following steps: carrying out the human body detection of a video stream, and determining a first region where a target object is located in the video stream; sampling the video stream to obtain K video frames of the video stream; determining a regional image group ofthe target object according to a first region of the target object in the K video frames; and performing event detection on the regional image group to obtain a detection result of the target object.According to the embodiment of the invention, the event detection accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to an event detection method and device, electronic equipment, and a storage medium. Background technique [0002] With the development of the economy and the continuous improvement of infrastructure construction, the application of escalators in shopping malls, office buildings, public transportation and other scenarios is becoming more and more extensive. While the escalator brings convenience, people pay more and more attention to the accidents that may be caused by abnormal movements of pedestrians on the escalator, such as falling, retrograde, squatting, etc. If the abnormal action on the escalator cannot be detected in time, and the operation of the escalator can be stopped in time, the life and property safety of the pedestrians on the escalator may be severely damaged. [0003] The detection scheme in the related art is usually based on infrared sensing...
