  • Publication number: 20230129175
    Abstract: The present disclosure relates to a traffic marker detection method and a training method for a traffic marker detection model, and relates to the technical field of intelligent transportation, and particularly to autonomous driving technology. The traffic marker detection method comprises acquiring a target image containing a traffic marker; and inputting the target image into a traffic marker detection model to obtain a detection mark corresponding to the traffic marker; wherein the detection mark comprises at least one of a detection point and a detection line for characterizing a position of the traffic marker in the target image.

  • Publication number: 20220319196
    Abstract: The present application relates to a method and an apparatus for detecting lane lines, an electronic device and a non-transitory storage medium. The method comprises: acquiring an image to be detected; determining at least one initial point in the image; extracting a position characteristic of at least one initial point; processing the position characteristic of the at least one initial point by using a first network model to obtain trend information of a corresponding lane line; and generating a target lane line containing the at least one initial point according to the trend information. In the present application, a network model is used to process a position characteristic of an initial point to obtain trend information of the lane line, and a complete lane line of the road image is quickly generated according to the trend information.

  • Publication number: 20220270377
    Abstract: The present application relates to a method and an apparatus for detecting corner points of a lane line, an electronic device and a storage medium. The method comprises: obtaining a road image to be detected; inputting the road image into a pre-trained neural network model to obtain a heat map prediction result, wherein the heat map prediction result comprises a probability of each pixel belonging to a specific corner point category; determining a plurality of different categories of corner points in the road image according to the probability of each pixel belonging to a specific corner point category in the heat map prediction result; and grouping the plurality of different categories of corner points according to a predetermined rule to obtain at least one corner point group. The present application can solve the problem that the corner points of the lane lines cannot be accurately and quickly detected.
