| Abstract: | Soil surface roughness has been widely used for characterizing soil surface profile.To rapidly measure soil surface roughness in situ,a laser scanner is developed based on triangulation principle.Compared with traditional instruments,this device has higher measurement resolution(0.1mm),precision positioning ability(1mm),and efficiency.A PDA(personal digital assistant) is used as data-logger,which can meet the requirements of portability,large data memory,and real-time data processing in field. |
