Summary:The invention belongs to the field of GPS positioning, and particularly relates to a complex road condition positioning method and system. The method comprises the following steps that S1, whether a vehicle reaches a preset position or not is detected according to a positioning system, and the preset position is a complex road condition position pre-stored in a database; s2, if it is detected that the vehicle arrives at the preset position, an external camera device of the vehicle is called to obtain environment information on the two sides of the vehicle; s3, after the environment information is preprocessed, effective feature elements in the environment information are extracted; wherein the effective feature elements refer to feature elements helpful for accurate positioning of the vehicle; and S4, analyzing the effective feature elements, and judging accurate positioning of the vehicle in the complex road condition according to an analysis result. According to the invention, accurate positioning of the ve
