The invention discloses an intelligent roadbed compacting system based on unmanned driving and information detecting techniques. The intelligent roadbed compacting system comprises an intelligent roadroller, a filler group image recognition device, a real-time moisture content detecting device, a central control host and a cloud control system. The filler group image recognition device is mountedat the top of a frame of the intelligent road roller, is wirelessly communicated with the cloud control system, and recognizes images of the filler particle size through analysis; the real-time moisture content detecting device is mounted on a roller of the intelligent road roller, performs on-board automatic detection on the moisture contents of different filler soil bodies, and sends signals tothe central control host through Bluetooth wireless communication. The intelligent roadbed compacting system has the advantages that techniques such as unmanned driving, path planning, continuous compaction detection, image recognition, moisture content detection and satellite positioning are integrated, roadbeds qualified in material and compaction quality are formed after raw material detection, rolling process control, dynamic adjustment ad compaction degree detection, and accordingly, automatic and intelligent compaction of the roadbeds is realized.
