车道线检测与分割:UNet与LaneATT算法原理解析 车道线检测是自动驾驶中最基本、最关键的安全任务之一,可以应用在 ADAS (高级驾驶员辅助系统)中,如车道保持功能,以及其他更高级别的自主任务(如与高清地图和轨迹规划的融合等)。给定在自动驾驶车辆上收集的 RGB 图像,车道线检测算法旨在图像上提供结构化线的集合。 车道...
A lane marking detection apparatus, a lane marking detection method, and a lane marking detection program is provided, which can detect a lane marking precisely even when noise is present. The lane marking detection apparatus is provided with an original image acquiring means which acquires an ...
4.Proposal prediction:为每一个anchor预测一个lane proposal。Lane proposal有三个组成元素:(i)类别(K+1)种可能,本文中k=1 (ii)Npts个offset,预测值与anchor line之间的偏移,Npts为纵向划分的个数 (iii)proposal的长度。proposal的起点s是对应anchor的y起点,终点为e=s+l-1。 proposal的结果是利用两个FC la...

边缘检测我们用的是Canny Edge Detection,是一种边缘检测的算法, cv2.Canny(img,low_threshold,high_threshold) 然后我们可以选择我们感兴趣的区域,可以提高准确度 这里使用的是cv2.fillPoly(),用它你需要在图像是选出你需要的所有顶点vertices cv2.fillPoly(mask, vertices, ignore_mask_color) ...
https://github.com/MaybeShewill-CV/lanenet-lane-detection 以前的CNN网络将所有的车道线检测出来,没做区分,需要后续处理区分出不同的车道线。本文的CNN网络模型可以直接区分不同的车道线,不需要后续处理。 这里设计了一个 multi-task network:lane segmentation branch 和 lane embedding branch。lane segmentation bra...

Robust 3D lane detection is the key to advanced autonomous driving technologies. However, complex traffic scenes such as bad weather and variable terrain are the main factors affecting the robustness of lane detection algorithms. In this paper, a generalized two-stage network called Att-Gen-LaneNet...
Being a line segment, the ratio of its length to breadth should be greater than 4:1 at least. Only segments with higher ratio were taken into account. Segments having area less than certain threshold but more than minArea can possibly represent small broken centre lane markings and hence ...
Line IoU loss 这里作者的motivation是Line是由一系列points构成的, 通常直接用smooth-l1 loss来回归这些点, 但是这种方式是将这些点独立看待的. 所以提出了LIOU Loss讲这些点看做一个整体来计算loss. 先计算点和点之间的IOU. 再计算整体的IOU. IoU = \frac{d_i^o}{d^u_i} = \frac{min(x_i^p + e...
