Abstract: Embodiments of this application disclose a lane line detection method and a related device, which may be applied to the field of computer vision in artificial intelligence. The method includes: First, features extracted by different layers of the neural network are fused to obtain a fused second feature map, so that the second feature map obtained through fusion processing has a plurality of layers of features. The second feature map has a related feature of a low-layer receptive field, which facilitates accurate regression of a lane line, and further has a related feature of a high-layer receptive field, which helps determining whether a lane line exists. Then, an output predicted lane line set is divided into groups, and due to limitation of a receptive field, each predicted lane line in each group has an optimal prediction interval. In this embodiment of this application, the optimal prediction interval of each predicted lane line is selected to integrate lane lines. Finally, a finally output predicted lane line is formed by combining advantages of different predicted lane lines, thereby improving lane line detection precision.
