Abstract

The present application provides a method, apparatus, computer device and storage medium for detecting objects thrown from height, the method including: setting up a video surveillance area for capturing a target video image in real time; detecting all moving objects within the target video image using a background modeling algorithm; tracking the detected moving objects using Kalman filtering to obtain trajectory characteristics and related parameters of the moving objects; identifying whether the moving objects are objects thrown from height through rule-based identification of objects thrown from height; performing classification using a Long Short-Term Memory (LSTM) network classification model, including inputting parameters of the moving objects as feature data into the LSTM, to obtain a classification result and determine whether a false positive occurs. The method has strong anti-interference ability and can effectively filter out moving objects other than objects thrown from height.
