AI Technical Summary
Technical Problem
Existing methods for detecting intersecting roads using autofocus devices or GPS and lane markings are unreliable due to the absence of necessary data or unclear markings, leading to potential collisions with cyclists and pedestrians at intersections.
Method used
An intersecting road detection device that identifies road and wall pixels in an image, using semantic segmentation to detect wall high-edge pixels adjacent to road pixels, determining the presence of intersecting roads based on these pixels.
Benefits of technology
Accurately detects intersecting roads, enabling timely warnings or collision avoidance measures, thus enhancing road safety.

Abstract
To appropriately detect an intersecting road that intersects a road on which a host vehicle is traveling.SOLUTION: An intersecting road detection device 15 includes: an acquisition section 3B that acquires information indicating road pixels corresponding to roads and wall pixels corresponding to walls included in a host vehicle front image; a first identification section 3C that identifies wall bottom portion pixels which are portions adjacent to pixels corresponding to host vehicle traveling road included in the road pixels among the wall pixels; a second identification section 3D that identifies wall high portion pixels which are portions higher than height of the host vehicle traveling road by a predetermined value or more among the wall pixels; a third identification section 3E that identifies wall high edge portion pixels which are portions adjacent to pixels other than the wall pixels among the wall high portion pixels; and a determination section 3F that determines that an intersecting road which is a road intersecting the host vehicle traveling road exists in a position of the pixels other than the wall pixels, when the pixels other than the wall pixels adjacent to the wall high edge portion pixels are the road pixels.SELECTED DRAWING: Figure 1
