Problems solved by technology

The recognition accuracy of these methods depends on the quality of the motion features, and different optimizations are required for different scenarios, so the versatility is poor
In addition, the accuracy of action recognition also depends on the dimension of the collected data. Three-dimensional data containing depth information or motion data based on binocular vision can record more relative position information than ordinary monocular vision motion data, so it is more It is easy to be identified, but the sensors it requires are also more complicated, and it is not easy to install it in the subway driver

Abstract

The invention provides an operation action identification method and device. The method comprises the steps that a to-be-identified video clip is acquired, wherein the to-be-identified video clip contains an action type; and the action type in the to-be-identified video clip is identified according to the to-be-identified video clip and a pre-established action identification logo model. Through the operation action identification method and device, information can be extracted layer by layer from pixel-level original data to abstract semantic concepts, extracted features have more efficient expression capability compared with manually designed features, and an operation action can be identified quickly and accurately.

Description

technical field [0001] The present invention relates to the technical field of machine vision modes, in particular to an operation action recognition method and device. Background technique [0002] Urban rail transit undertakes large-scale transportation tasks between the city and the suburbs. It is an important part of the modern urban public passenger transportation system, and it is particularly important to ensure its operation safety. According to the statistical data of accidents in my country's rail transit system, among the causes of major traffic accidents, human factors such as train driver's operating errors account for a major proportion. Therefore, real-time monitoring of train drivers, early detection of operating errors and warnings and corrections have very important practical significance for reducing safety accidents and casualties. [0003] However, the existing driver monitoring systems are mostly used to monitor the physical state of the driver. For e...
