Abstract
Some embodiments of the present disclosure disclose a vehicular lane line data processing method, apparatus, storage medium, and device. The method includes: acquiring at least two consecutive original images of a vehicular lane line and positioning data of the original images; calculating, using a deep neural network model, a pixel confidence; determining an outline of the vehicular lane line and using the outline of the vehicular lane line as a candidate vehicular lane line; calculating a vehicular lane line confidence; filtering the candidate vehicular lane line; recognizing attribute information of the vehicular lane line; and determining map data of the vehicular lane line. The vehicular lane line data can be efficiently and precisely determined, the labor costs in high-precision map production is greatly reduced, and the mass production of high-precision maps can be achieved.
