The invention discloses an outdoor blind guiding method and system based on combination of navigation and blind sidewalk tracking. The method comprises the following steps: step 1, acquiring an initial navigation path, related information of a blind guiding vehicle and front road information of the blind guiding vehicle; step 2, according to pavement information of a front road, distinguishing road sections to which the front road belongs, wherein the road sections are divided into sidewalks, roads and other road sections; if a sidewalk is distinguished, entering a step 3; if a road is distinguished, entering a step 4; if the road section is distinguished as the other road sections, entering the logic of walking close to the roadside, and entering a step 5; step 3, detecting a blind sidewalk on the sidewalk, tracking the blind sidewalk, and entering the step 5; step 4, detecting a sidewalk on the road, and entering the step 3 according to the detected sidewalk; step 5, judging whether the front road has an obstacle or not, if so, entering a step 6, and otherwise, returning to the step 2; and step 6, parking or bypassing by changing a local path until no obstacle is judged, and returning to the step 2.
Description
technical field [0001] The invention relates to the technical field of blind guide vehicles, in particular to an outdoor blind guide method and system based on the combination of navigation and blind path tracking. Background technique [0002] The travel of the blind has always been one of the livelihood problems existing in the current society. In people's cognition, blind roads can help blind people travel to a certain extent, but due to the complex outdoor conditions, such as: the road conditions are too complicated, the construction of blind roads is not standardized, the occupation of various blind roads, intersections without sidewalks, and traffic lights also lack voice. For reasons such as reminders, it is still very difficult for the blind to travel. Guide dogs after training can also guide the visually impaired to go out, and can also guide the owner to avoid obstacles in time to avoid danger. However, the number of guide dogs is rare, and they can only remember...
