The invention discloses a lane curvature acquisition method and device, a vehicle, a medium and equipment, and belongs to the field of data processing. The method comprises the following steps: calculating direction angle offsets of a starting point and an ending point of a target lane; calculating the average radius of the target lane by using the distance and the direction angle offset of the target lane; calculating the number of segments of the target lane according to the average radius to obtain a first number of target lane segments; respectively extracting a front lane segment and a rear lane segment according to the lane passing direction of the target lane; performing curve fitting on the front lane segment, the target lane segment and the rear lane segment to obtain a second number of fitting curves and corresponding curvatures thereof; fitting check is carried out on the second number of fitting curves and the target lane segments, and an average error is obtained; and outputting the curvature of the target lane by using the second number of fitting curves and the average error. According to the method, the consistency of curvature precision and the high efficiency of curvature acquisition are effectively ensured.
