Abstract

The invention relates to the technical field of computer vision tracking, in particular to an outdoor scene classification method, comprising the following steps: S1, carrying out image segmentation by adopting an SLIC algorithm to form a tightly regulated small area; S2, extracting features of the small area and extracting feature vectors used for expressing the area; S3, using a bag-of-word method semantically to classify the segmented regions. The invention has the advantages of effectively reducing the calculation time of scene classification and more real beneficial effect for boundary treatment of different types of pavements.

Description

technical field

[0001] The invention relates to the technical field of computer vision, in particular to an outdoor scene classification method and system. Background technique

[0002] For intelligent mobile devices such as outdoor unmanned vehicles, it is a very important technology to be able to segment and recognize the surrounding scenes. In unstructured scenes in the wild, since there are no obvious signs such as lane lines in urban traffic, it is necessary to segment and classify different landforms in the scene to guide smart mobile devices such as unmanned vehicles to obtain feasible motion areas, thereby Help unmanned vehicles to perform local path planning and realize the function of autonomous driving or assisted driving. In this field, the method of pattern classification based on pixel points or small neighborhoods is used more directly, traversing all regions of the image, classifying all regions, and finally merging regions of the same category. The disadva...
