3.1.2 A-frame and base plate
The pod can rotate vertically around the vertical pivot at the top of the A-Frame. The fixed angles are 90° (horizontal),
45° and 0° (vertically up).
Changing the vertical inclination of the Merlin can help to produce more useful data, depending on the nature of the
scene being scanned and on the specific project requirements.
Leave the pod horizontal – at 90° – to generate vertical sections of points as the laser rotates.
Incline the laser to 45°, and the section of scanned points is also inclined. This can help to pick out vertical features
such as lamp posts, pillars and building edges.
