The invention relates to a universal road and lane detection system and method. The method comprises: S300, interference elimination and image artifact and irrelevant image part removing are carried out on an input image to obtain a relevant image; S302, lane edge feature or road edge feature is extracted from the relevant image; S304, according to the lane edge feature or road edge feature, fitting is carried out to obtain a synthesized path expression model; S306, the path expression model is tracked to carry out time sequence consistency integration or position consistency integration; and S308, the path expression model corresponds to a global coordinate system. On the basis of the module design, pretreatment is carried out on the image inputted by the camera, the interested relevant image is selected; lane detection or road detection is carried out by combining input information of the laser radar; model fitting is carried out to estimate a road path and the accuracy of path estimation is improved by using the time sequence integration module; and then the image corresponds to the global coordinate system in real time by using a coordinate system correspondence module to improving path estimation accuracy. Therefore, a problem that the existing road estimation model has imperfect functions can be solved.
