Vanishing Point: a Visual Road-Detection Program
نویسندگان
چکیده
This report describes a visual approach to road detection. A field of dominant trend lines is established over the image, by convolution with Gabor filters; the trend lines are then grouped into "visual segments," providing evidence for macroscopic linear features. Sets of these macroscopic features are evaluated against a list of heuristic criteria, to determine their likelihood of representing a road in the image. This procedure was implemented as software, for use by the Indy Robot Racing Team, a participant in the DARPA Grand Challenge 2005. It is capable of road detection at rates appropriate for driving at moderate speeds on dirt roads (ca. 5 Hz on a 3.4 GHz processor).

Visual Campus Road Detection for an UGV using Fast Scene Segmentation and Rapid Vanishing Point Estimation
Vision-based road detection plays a key role for Unmanned Ground Vehicles (UGVs) working in an unknown outdoor environment. The estimation of the vanishing point is a practical solution for general road detection using monocular vision, which however is not good enough for robust road detection in a campus environment due to the strong noises of texture orientations generated from roadside tree...

In this paper a robust method for visual motion estimation under ego{motion is developed. The possible application of this method is image sequence analysis of road tra c or airport runway/taxiway scenes, where the camera is located in a moving vehicle. The method combines an application independent estimation of visual motion with speci c methods for instantaneous detection of the vanishing po...

Vanishing-point detection is an important component for the visual navigation system of an autonomous mobile robot. In this paper, we present a novel line space voting method for fast vanishing-point detection. First, the line segments are detected from the road image by the line segment detector (LSD) method according to the pixel's gradient and texture orientation computed by the Sobel operat...

We present an approach for adaptive object placement for Augmented Reality (AR) use in driver assistance systems. Combined vanishing point and road surface detection enable the real-time adaptive emplacement of AR objects within a drivers’ natural field of view for on-road information display. This work combines both automotive vision and multimedia production aspects of real-time visual engine...
متن کاملDetection of Lane Departure on High-speed Roads
We present a system for detecting and tracking the lanes of high-speed roads, in order to warn the driver of accidental lane departures. The proposed method introduces a novel variant of the classic Hough transform, better equipped to detect and locate linear road markings with a common vanishing point. This is combined with a simple model of the lane and an Extended Kalman Filter to make detec...
