Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] First, refer to figure 1 A method for creating a model of a physical scene according to an embodiment of the invention is described.

[0024] figure 1 is a flowchart illustrating the main steps of a method for creating a model of a physical scene including various objects according to an embodiment of the invention. The method can be applied to any electronic device with processing capabilities, such as a computer, a console (such as a control center in a car), a server, and the like. The physical scene may be various scenes in the real world, such as indoor scene, outdoor scene and so on. The physical scene includes multiple objects of different types. For example, when the physical scene is a road environment, the various objects may include at least two of lanes, shoulder stones, fences, intersections, traffic signs, traffic lights, trees, ...

Abstract

A method and apparatus for creating a model of a physical scene including various objects, and a method and apparatus for assisting driving are provided, the method comprising: acquiring an image of the physical scene; Extracting the feature of each of the multiple objects; judging whether there is a scene model; when judging that there is no scene model, initializing the scene model based on the features of each of the extracted objects to obtain the initialization scene model; and outputting the initialization scene model.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, the present invention relates to a method and device for creating a physical scene model, and a method and device for assisting driving. Background technique [0002] In the field of image processing, it is of great significance to create a model of the physical scene. Taking the road environment as an example, the road environment model is an important part of the Advanced Driver Assistant System (ADAS). After the road environment model is established, many applications in ADAS such as lane departure warning, autonomous cruise control and emergency braking will become more accurate and simpler and more feasible. [0003] In an existing road environment model, a single model is modeled for an object in the road environment, such as a lane line model, a road edge model, etc., which contains a single object and cannot reflect various aspects of the real physical scene...
