| 摘 要： | 针对传统视觉系统视野有限的问题,提出了一种基于环视系统的车位检测方法。环视系统由4个鱼眼相机构成,对每个相机获取的图像进行畸变校正和逆透视变换得到鸟瞰图;使用加权平均融合的策略将4幅鸟瞰图拼接融合为一幅环视图,该环视图像能显示的左右最远距离能达到7.5m;在环视图的基础上,提出了一种新颖的车位检测算法,该算法利用LSD(Line Segment Detector)算法检测环视图像中的直线。实验表明,该方法比常用的霍夫变换具有较高的检测精度和鲁棒性,并且能够达到实时的要求。

| Abstract: | In this paper,a parking slot detection method based on the Around View Monitor(AVM)system was introduced.The top view of each camera is obtained by correcting distortion and inversing perspective transformation;Based on the weighted average fusion strategy,the panoramic image is obtained.This paper proposed a novel vision-based automatic parking slot detection method by utilizing a Line Segment Detector(LSD)to detect lines on the panoramic image.Experimental results show that the proposed method performs better and can realize real-time requirement. |
