RiMTA 3D

RiMTA 3D calculates the most probable MTA zone for each measurement automatically.

Acquiring data in terrestrial laser scanning with high measurement rates over long ranges frequently results in range ambiguities. Instruments with multiple-time-around capability (MTA), like the RIEGL VZ-4000, include information in the provided data which the post-processing software can utilize in to resolve these ambiguities. Instead of asking the user to manually specify the correct MTA zone for each data set or even subset, RiMTA 3D calculates the most probable MTA zone for each measurement automatically. In order to correctly determine the range to the target with LIDAR instruments using time-of-flight measurements with short laser pulses requires to correctly determine the correlation of each received echo pulse to its causative emitted laser pulse. However, at high pulse repetition rates (PRR) and large target ranges this definite allocation becomes ambiguous due to a limiting factor which may not be tweaked by engineer's skills: the speed of light. At a PRR of 300 kHz the range of unambiguity is limited to only 500 meters, a measurement distance which is routinely exceeded by RIEGL terrestrial laser scanners (TLS).
