The invention relates to the technical field of automatic driving, in particular to a lane line precision measurement method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the current observation data and historical observation data of the vehicle for a lane line; solving the current observation data and the historical observation data, and generating a target truth value and a target curve solution set; and calculating all curves in the target curve solution set, obtaining a target parameter point set of all the curves, and calculating a precision metric value of the lane line by using a difference value between the truth value and a corresponding parameter point in the target parameter point set. According to the embodiment of the invention, the approximate truth value of the intercept between the vehicle and the lane line can be obtained through optimization or filtering fusion solution, statistical data analysis of multi-frame historical fusion lane line data and the approximate truth value is carried out, a quantized lane line precision measurement value is obtained, the reference truth value of the lane line in the measurement process is obtained, and the measurement accuracy of the lane line is improved. Therefore, the efficiency and accuracy of lane line precision measurement are improved, and the practicability is higher.
