Abstract

The invention discloses a method and system for detecting obstacles on the road surface, and relates to the technical field of intelligent vehicle environmental sensing systems. The road obstacle detection method controls the opening and closing of the first laser and the second laser according to the pulse sequence of the first CCD camera, improves the effective detection distance, and reduces the average output power consumption of the structured light source; for the first CCD camera from the first The first black-and-white image is obtained after the frame data of the moment and the second moment are subjected to difference operation; the second black-and-white image is obtained after the frame data of the first moment and the second moment from the second CCD camera are subjected to difference operation; the first black-and-white image is The structured light strip image is obtained after the difference operation with the second black-and-white image, which overcomes the interference of ambient light on the extraction of structured light strips during traffic driving, and improves the environmental adaptability of the system.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicle environmental sensing systems, in particular to a method and system for detecting road obstacles. Background technique [0002] Accurate detection of obstacles is the key to avoiding collisions, and it is the core issue of intelligent vehicle environment perception. Target detection using structured light vision sensor is an active detection technology based on image processing. However, the current structured light vision inspection system is only suitable for short-distance inspection tasks in indoor good light environments, such as indoor mobile robots, product quality inspection and 3D reconstruction. The current structured light visual inspection system is limited by factors such as human eye safety, light source power, and structured light generation methods when used in vehicles, and it is difficult to meet the requirements of smart vehicles in terms of detection distance and a...
