A ScanLook scan using the FARO at 30 degree tilt and about 7.5 high from the back of a van:
At the same time the Velodyne tilted upwards at 45 degrees, just about 1 foot higher:
Notice the drastic reduction in shadowing from the Velodyne scan.
*Note: The top picture shows the amount of shadowing that can and will occur using any single line, single scanner mobile system. It is very similar to the shadowing from a static scan (hence the many setups required with a static scanner to capture most scenes). Using a dual, butterfly pattern with single line scanners will significantly reduce the amount of shadowing but it will still not be nearly as complete as the Velodyne HD32 with 32 lasers in a 40 degree FOV.
