An outdoor blind guiding method and system based on the combination of navigation and blind path tracking

Abstract

The invention discloses an outdoor blind-guiding method and system based on the combination of navigation and blind road tracking. The method includes: step 1, obtaining preliminary navigation path, information about the blind-guiding vehicle, and road information ahead of the blind-guiding vehicle; step 2, According to the pavement information of the road ahead, identify the road section to which the road ahead belongs, and the road section is divided into sidewalk, road and other road sections; if it is identified as the sidewalk, go to step 3; if it is identified as the road, go to step 4 If it is identified as the other road sections, then enter the logic of walking on the side of the road, and enter step 5; step 3, detect the blind road on the sidewalk, and follow the blind road, and enter step 5; step 4, detect the blind road. Describe the sidewalk on the road, and according to the detection of the sidewalk, enter step 3; step 5, judge whether there is an obstacle on the road ahead, if yes, then enter step 6, otherwise, return to step 2; step 6 , stop the vehicle or make a detour by changing the local path until it is judged that there is no obstacle, and return to step 2.

Description

technical field [0001] The invention relates to the technical field of guide cars, in particular to an outdoor blind guide method and system based on the combination of navigation and blind lane tracking. Background technique [0002] Blind travel has always been one of the livelihood problems in the current society. In people's cognition, the blind road can help the blind to travel to a certain extent. However, due to the complex outdoor conditions, such as: the road conditions are too complex, the construction of the blind road is not standardized, the occupation of various blind roads, the intersections without sidewalks, and the traffic lights also lack voice. For reasons such as reminders, it is still very difficult for the blind to travel. The trained guide dog 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 scarce, and they can only remember a fixed route. T...
