Abstract

Mobile laser scanning is an emerging technology for accurate and fast surveying and surveillance applications. By using RIEGL's new V-line laser scanners with online waveform analysis capable of discriminating multiple targets per laser shot, true 3D information can be obtained. Thus the detection of objects concealed by vegetation or camouflage tarps is facilitated. We present experimental results disclosing a vehicle hidden behind bushes employing a terrestrial laser scanning system. The laser scanner offers measurement rates of up to 125 kHz and ranging capabilities up to 500 m at a scan range of 360° for the frame and 100° for the line axis. The obtained experimental results prove that multi-target capability is mandatory for the envisaged application. In dense vegetation, up to 10 targets per laser shot are identified.
