	ASM     Topcon ASM (Accurate Surface Modelling) Products will deliver 3D Measurement / Digital Modelling Solution. 3D Area Measurement Solution Many choices of sensor have been available for "Point to Point" measurement solution, such as total station. Then, what is the solution for "Area Measurement" available today ? Yes, you could find several choices. However, really practical and cost effective system is still hard to find. Topcon introduces the revolutionaly new solution for this with innovative technology, "Virtual Scan System" and "Field Scan Robo System", both of which are fully taking advantage of new digital image processing technology.   Virtual Scan Pro Virtual Scan Lite Field Scan ROBO Application 3D Measurement and DSM Modelling 3D Measurement and DSM Modelling 3D Measurement and DSM Modelling Recommended for wide area modelling Recommended for wide area modelling Recommended for local area modelling Method to measure Digital Image Processing Digital Image Processing Distance/Angle Measurement Field Work Time (relatively) Very fast Fast Normal In-Office processing time Normal Fast Very Fast (Not required) Measurement Range 250m 250m 120m (Normal Mode) (3000m : 1Prism) (3000m : 1Prism) 30-1200m (Long Mode) Accuracy Plain(counterview) : dXY=H/f x dP Plain(counterview) : dXY=H/f x dP +/-(3mm+2ppm)m.s.e.
