【摘要】：为提高弯曲道路的消失点检测效果,提出一种新的非结构化道路消失点检测方法。利用垂直投影校正方法校正投票点的Gabor纹理主方向,采用纹理主方向和边缘信息对投票点上方的一系列投票点权值进行加权,并通过投票点权值完成主方向加权投票,从投票点中选择接收的投票值之和最多的候选点为消失点,从而实现消失点检测。实验结果表明,与现有非结构化道路消失点检测方法相比,该方法对于弯曲道路具有更低的运行时间及更高的检测准确率。
[Abstract]:In order to improve the detection effect of vanishing point of curved road, a new method for detecting vanishing point of unstructured road is proposed. The method of vertical-projection correction is used to correct the Gabor texture principal direction of the polling point, and the texture main direction and edge information are used to weighted a series of voting point weights above the polling point, and the voting point weight is obtained by the voting point weight value. The vanishing point is chosen as the candidate point which has the most sum of the received voting values from the polling point, thus the vanishing point detection is realized. The experimental results show that the proposed method has lower running time and higher detection accuracy than the existing methods for detecting the vanishing points of unstructured roads.
