The invention provides a road surface evenness detector and a road surface evenness measuring method. The road surface evenness detector comprises a two-axis acceleration sensor, a laser distance measuring sensor, a mileage counting sensor, a gyroscope and a processor. The two-axis acceleration sensor is used for measuring the first acceleration in the direction perpendicular to the road surface evenness detector and the second acceleration in the direction parallel to the road surface evenness detector. The laser distance measuring sensor is used for measuring the distance between the road surface evenness detector and a road surface to be detected. The mileage counting sensor is used for measuring the horizontal displacement of the road surface evenness detector. The gyroscope is used for measuring the real-time rotation angle between the road surface evenness detector and the horizontal road surface. The processor is used for processing the measuring values and obtaining the road surface evenness of the road surface to be detected. According to the technical scheme, errors caused by rotational motion of a chassis of a detected vehicle are avoided, and the precision of the road surface evenness detector is improved.
