The present invention provides a LiDAR system capable of detecting a road surface, which acquires a location through comparison with point group data on the basis of mapped road surface information during a process of detecting the state of a road surface. The LiDAR system comprises: a first unit and a second unit. The first unit includes: a first LiDAR head which transmits a first optical signal towards the road surface, and receives a second optical signal that includes point group data corresponding to the road surface and results from the reflection of the first optical signal by the road surface; and a first control unit which performs an intensity correction on the point group data of the second optical signal and forms mapping information including information on the road surface. The second unit includes: a second LiDAR head that receives the mapping information from the first unit, transmits a transmission signal towards the road surface, and receives a reception signal that includes point group data corresponding to the road surface and results from the reflection of the transmission signal by the road surface; and a second control unit which acquires a location by matching the mapping information with the point group data included in the reception signal. The present invention enhances reliability.
