Abstract

The invention discloses a lane line pressing detection method and system, and the method comprises the steps: obtaining a bird's-eye view road image corresponding to one wheel at a current moment; determining a wheel outer side edge tangent line of the wheel according to a setting parameter of a camera which is used for obtaining the bird's-eye view road image; carrying out the image processing ofthe bird's-eye view road image, and determining a lane edge line; judging whether the lane edge line is intersected with the wheel outer side edge tangent line or not: determining that the wheel presses the lane line if the lane edge line is intersected with the wheel outer side edge tangent line. Because the bird's-eye view road image of the wheel is captured by the camera fixed above the wheel,a tangential equation of the outer side of the wheel can be determined through simple calculation, thereby facilitating the recognition of a wheel pattern in the image, reducing the data processing burden of a processor, simplifying the data calculation process, and improving the data calculation efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic driving evaluation, in particular to a method and system for detecting lane-marking lines. Background technique [0002] With the rapid development of unmanned driving technology, the related test and evaluation technology is also developing simultaneously. In the initial stage, each R&D unit will test and evaluate the individual or partial functional requirements of its R&D vehicles according to their own conditions. With the maturity of system integration technology and unmanned driving technology, third-party evaluation agencies focusing on smart car competitions have also emerged. [0003] In the field of unmanned vehicle testing, whether an unmanned vehicle is driving or not is an important indicator for evaluating its intelligence. Existing methods for judging whether a smart car presses a lane line or violates traffic rules are usually manually judged by a referee. However, the referee...
