Problems solved by technology

The disadvantage is that in a complex environment, it is necessary to distinguish the detected target from the background, and the amount of calculation required to extract useful information is very large. Solving it solely with hardware conditions will easily lead to poor real-time performance of the system.

Abstract

The invention provides a vehicle obstacle avoidance method and a vehicle obstacle avoidance system based on machine vision. The obstacle avoidance method comprises the following steps: judging whether an obstacle exists in front of a micro vehicle by a processor by using a obstacle detection algorithm based on a single image; calibrating two cameras, determining the height of the obstacle through a stereoscopic vision method and transmitting height information to a controller by the processor; detecting conditions of vehicles in two adjacent lanes by distance measuring equipment to provide a running area for the vehicles to avoid the obstacle and change a lane and transmitting running area information to the controller; and according to the obtained information, transmitting a command to a operation and control module by the controller through using an adaptive lane change strategy to complete autonomous lane change of the vehicles. The obstacle avoidance method provided by the invention has the advantages of being stable, high in adaptive degree, fluent in vehicle obstacle avoidance posture and up to 98% in obstacle avoidance success rate.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a machine vision-based vehicle obstacle avoidance method and system. Background technique [0002] With the acceleration of urbanization, the existing transportation infrastructure and management methods lag behind the development of the times. Simply by widening roads, building elevated roads, laying rail transit, setting up signs, encouraging public transportation, and even air traffic, relying on traditional methods is far from being able to adapt to the development of modern transportation, and requires the development of intelligent transportation systems. The intelligent transportation system is a real-time, accurate and efficient transportation system with a large scope and full range of functions established by effectively comprehensively applying advanced information technology, data communication transmission technology, control technology and artific...
