Method and system for pavement detection of automatic navigation vehicle

Abstract

The present invention is suitable for the automatic navigation vehicle field, and provides a method and system for pavement detection of an automatic navigation vehicle. The method comprises: performing real-time detection of barriers hanged or having height being lager than the chassis height of an automatic navigation vehicle on a front pavement, and generating obstacle avoidance alarm information when detected barriers cannot be avoided; performing real-time detection of the barriers on the front pavement through a contact detection mode, and generating collision avoidance alarm information when the barriers are detected; performing real-time detection of the dimensions of the barriers or the dimensions of a channel on the front pavement, and generating path-finding alarm information when the detected barriers or the channel cannot be spanned; and according to the obstacle avoidance alarm information, the collision avoidance alarm information and the path-finding alarm information, controlling the operation state of the automatic navigation vehicle. The method and system for pavement detection of the automatic navigation vehicle detect channels or barriers which cannot be spanned, fine stick objects difficult to be detected or hanged barriers on the front pavement to eliminate a detection blind area, allow the automatic navigation vehicle to avoid barriers or channels and realize self protection.

Description

technical field [0001] The invention belongs to the field of automatic guidance vehicles, and in particular relates to a road surface detection method and system for automatic guidance vehicles. Background technique [0002] Existing In recent years, automatic guided vehicles have been widely used in unattended occasions such as factory handling and substation inspection. Since the automatic guided vehicle operates in an unattended place, it is required to automatically avoid or protect itself when encountering obstacles that cannot be crossed. Most of the existing automatic guided vehicles are designed with the function of avoiding obstacles automatically. [0003] However, existing automatic guided vehicles have blind spots when detecting the road surface, for example: there are ditches or obstacles that cannot be crossed on the road ahead of the automatic guided vehicle, small sticks or suspended obstacles that are difficult to detect When special circumstances such as,...
