In intelligent vehicle systems, lane detection is one of the most important parts. This paper presents a lane detection algorithm that based on Hough transform. Principle of the algorithm and the implementation base on OpenCV are discussed in detail. The algorithm was verified at the end of this paper.
The vision based Lane Departure Warning System (LDWS)is a effective way to prevent Single Vehicle Road Departure accident. In practice, a variety of complex noise make it very difficult to detect lanes fast and accurately, so to establish a set of image processing method which can give results fast and accurately in the non-ideal conditions is the primary work. In this paper, a lane detection method...
In this paper, we propose a multi-step algorithm for curved lane detection. We represent the lane markings on the road by a modified hyperbola-pair model, which contains two parts. The first one is a parallel straight line model, which is achieved by Hough transform. The second one is a hyperbola-pair line model, which is achieved by a searching strategy with the parameters got in the first stage...
This paper proposes a method of lane marker detection for platooning. In order to reduce air resistance, it is desirable to shorten the distance between two vehicles. If the vehicular gap is very short, conventional methods, which detect lane markers ahead in images captured from a front camera, are useless because lane markers are occluded by a vehicle in front. To solve this problem, the proposed...
In this paper, we propose a road sign detection and recognition algorithm for an embedded application. The algorithm is based on the Hough transform method to detect lines in order to identify and determine the shape of the road sign. Shape measurements are currently employed to identify the road sign ratios of area and perimeter. The variables are compared with the template library which we have...
This paper discusses a moving target detection method based on road extraction in SAR images. Firstly road pixels are initially extracted by fuzzy C mean (FCM) clustering. Then the image is divided into sub-block and the Hough transform is used to extract the segment candidates in each block. Combining the proximity, the con-linearity and the membership of the segment candidates, the reasonable roads...
People have a growing interest for driver assistant systems that are used to monitor the driving conditions by visual technique, and warn and guide drivers the road conditions. This paper proposes a real-time lane detection algorithm which is a necessary part for driver assistant system and unmanned vehicle. The algorithm presented in this paper integrates multiple cues, including bar filter which...
Image multi-scale edge detection based on anti-symmetrical biorthogonal wavelet is given detailedly in theory, Especially an algorithm of wavelet decomposition in which multi-scale edge can be detected is put forward. Based on above using different kinds of wavelet decomposition data such as approximate coefficients and multi-scale edge image, a moving object detection approach in active video surveillance...
In a previous paper, a simple approach to lane detection using the Hough transform and iterated matched filters was described. This paper extends this work by incorporating an inverse perspective mapping to create a bird's-eye view of the road, applying random sample consensus to help eliminate outliers due to noise and artifacts in the road, and a Kalman filter to help smooth the output of the lane...
Traffic sign recognition is a technology which allows us to recognize signs in real time, typically in videos, or sometimes just (off-line) in photos. It is used for Driver Assistance Systems (DAS), road surveys, or the management of road assets (to improve road safety). In this paper, we propose a method for general traffic sign recognition (tested for the New Zealand road signs) which combines previously...
This paper presents a vision-based road-barriers detection method. Because horizontal structures are hard to detect by binocular stereovision, object detection methods based on 3D points grouping fail to detect the barriers as obstacles and consequently specific ACC applications as longitudinal control will fail to react when the vehicle path is obstructed by such an object. Therefore the proposed...
Road detection is a crucial part of autonomous driving system. Most of the methods proposed nowadays only achieve reliable results in relatively clean environments. In this paper, we combine edge detection with road area extraction to solve this problem. Our method works well even on noisy campus road whose boundaries are blurred with sidewalks and surface is often covered with unbalanced sunlight...
Road identification and detection is the essential problem to be solved in intelligent vehicle systems. As the complexity dimension of the surrounding environment increases, road recognition becomes much harder under different interferences. To increment the robustness and interference immunity, a diffused region of Hough based road detection algorithm is proposed in this paper. This algorithm incorporates...
The Driving Assistance Systems (DAS) aim to help the vehicle drivers to proceed through different road situations. However, their main task is not only to safe one particular driver, but also to increase the safety for all traffic members. The problem domain here is huge and might be divided into the subtopics, like driverpsilas fatigue detection, pedestrian tracking, obstacle collision avoidance,...
In this research the problem of the detection and classification of road bridge sign has been faced, in particular, at butterfly bridge configuration. The first step concerns the robust identification of the rectangular sign, through the optical flow analysis. The second step concerns rectangular sign detection based on searching gray level discontinuity on the image and Hough transform. The classification...
