Abstract

The invention discloses a video behavior recognition method and device, and relates to the technical field of video behavior recognition. A specific embodiment of the method comprises the following steps: inputting video data collected by a target camera into a feature model to output a feature vector of the target camera; respectively calculating the distance between the feature vector of the target camera and the feature vector corresponding to each camera group, and screening the camera group most similar to the target camera; and taking the video behavior recognition model corresponding to the camera group as a video behavior recognition model of the target camera, and performing behavior recognition on video data collected by the target camera. According to the embodiment, the technical problem that a large amount of data acquisition and labeling work consumes a large amount of time and manpower can be solved.

Description

technical field [0001] The present invention relates to the technical field of video behavior recognition, in particular to a video behavior recognition method and device. Background technique [0002] Video behavior recognition technology can be used to identify human actions in videos, and this technology is being increasingly used in video surveillance systems. The core of video behavior recognition technology is the video behavior recognition model. Currently, models with high recognition accuracy are usually implemented using convolutional neural networks including 3D convolutional layers. However, training a high-precision video behavior recognition model requires a large amount of labeled data. In actual scenarios, a pre-training model is usually selected. This pre-training model is generally trained using historical data sets of other similar The set is trained on the basis of the pre-trained model, and the model trained in this way can obtain a higher accuracy rate...
