Abstract:
A section line recognition device is realized which can determine a line type of a section line in a road surface with high accuracy. In step 301, a feature amount is extracted from an image captured by each camera. This step corresponds to a process of a feature point extraction unit. In the next step 302, the extracted feature amount is transformed into bird's-eye view coordinates which is common coordinates. This step corresponds to a process of a coordinates transformation unit. Next, in step 303, a camera to be selected is determined. This step is a process of a camera determination unit. Next, in step 304, the state transition at the appearance position of the feature point on the bird's-eye view coordinates is determined using feature point coordinates of the camera selected in step 303. This step is a process of a state transition determination unit. Finally, in step 305, the line type is determined. This step is a process of a line type determination unit.
