Abstract

The invention provides a rail transit scene graph generation method and device, equipment and a storage medium, and the method comprises the steps: obtaining a rail transit image, and marking a target region in the rail transit image according to an attention mechanism; and inputting the rail transit image marked with the target area into the generative model to obtain a rail transit scene graph output by the generative model. According to the method adopted by the invention, through visual perception of the rail transit scene and interaction between objects in the image, higher-level scene understanding is achieved, and the visual situation of the rail transit scene is represented by using the scene graph.

Description

technical field [0001] The invention relates to the technical field of rail transit systems, in particular to a method, device, equipment and storage medium for generating a rail transit scene graph. Background technique [0002] With the improvement of computing power and model capabilities, people's cognitive understanding of scenes is no longer limited to object detection. In recent years, some studies have focused on the visual knowledge description of the entire image, which is not only a collection of objects, object attributes, and image attributes, but also Representation of relationships between objects. Visual cognition of rail transit scenes is one of the core technologies in the field of rail transit systems. For rail transit scenarios, understanding the interactions between objects in an image can lead to a higher level of scene understanding. [0003] In the prior art, some characteristics of the objects themselves in the rail transit scene are ignored, and t...
