Multi-lane line optimization method and device, electronic equipment, storage medium and program

The invention relates to a multi-lane line optimization method and device, electronic equipment, a storage medium and a program product. The method comprises the steps of obtaining a road image; performing lane line detection on the road image to generate a lane line data set, wherein the lane line data set comprises discrete point data of a plurality of lane lines; constructing a curvilinear equation corresponding to the plurality of lane lines based on parallel constraints of the lane lines; and according to the lane line data set and the curvilinear equations corresponding to the plurality of lane lines, based on a least square method, obtaining a target curvilinear equation corresponding to the plurality of lane lines. According to the method and device, curvilinear equations corresponding to the multiple lane lines are constructed based on the parallel constraint of the lane lines, so that the calculation amount in the fitting process of the multiple lane lines is greatly reduced; based on the least squa
