Scanning Technology
The laser scanner produces an optical pulse that is transmitted, reflected off an object, and returned to the scanner’s receiver. With the pulse travelling at the speed of light, the travel time of the pulse can be converted into a range measurement. Combining the laser range, laser scan angle, laser position from GPS, and laser orientation from INS, accurate 3D target coordinates can be calculated for each pulse. This is a robust and reliable technique that can be used in most weather conditions.
The 3D coordinates are stored on a data recorder and can be post-processed using specialist software. The software imports the laser scanner points in the form of a point cloud that can then be manipulated according to the customers requirements. |
