Abstract

The invention discloses a method and device for detecting a lane obstacle and relates to the technical field of computers. A specific embodiment of the method comprises a step of determining a reference offset set of a to-be-detected road segment of a lane, wherein an offset in the reference offset set is a distance from a driving track point corresponding to the lane in the to-be-detected road segment to a lane baseline when the to-be-detected road segment of the lane has no obstacle, a step of determining a detection offset set of the to-be-detected road segment of the lane in a preset timeperiod, wherein the an offset in the detection offset set is a distance from a driving track point corresponding to the lane in the to-be-detected road segment to the lane baseline in the preset timeperiod, and a step of judging whether the to-be-detected road segment of the lane has the obstacle according to a similarity between the detection offset set and the reference offset set. According tothe method, the lane obstacle is detected without another detecting device, the problem that a detection blind zone occurs because of limited coverage in the prior art is solved, and the detection cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for detecting lane obstacles. Background technique [0002] The existence of obstacles on the lane will seriously affect the driving of vehicles on the lane, such as illegal parking on the bicycle lane, which will not only cause traffic congestion, but also likely to cause traffic accidents. In the prior art, the methods for detecting whether there is an obstacle on the lane mainly include: monitoring through cameras at fixed points, and relying on human identification. [0003] Both manual recognition and fixed-point video information collection are active detection methods, and the probability of detection failure is relatively high. Moreover, the coverage of each detection point is very limited (in the line of sight of people and cameras), so it requires a lot of manpower and material resources, resulting in high detection costs.
