Users can choose from four different filters for pre-processing, including an average/median filter, maximum filter and a remission filter. The average/median filters are used to minimize noise level and to achieve higher measurement precision. The maximum filter helps reduce disturbed measurements by dust or very small objects such as raindrops in the near field to ensure reliable operation outdoors and in harsh environments. The remission filter helps suppress low reflective targets by separating measurements on reflectors and natural targets in the scanner itself.
Skip Scan Function
The Skip Scan function allows to reduce the output frequency of scans over a scan data connection in comparison to the recording frequency of scans as defined by the global parameter scan frequency so that only, e.g., every second scan is transferred and the output of the next is suppressed. This option is useful for applications that require a high scan frequency in order to reduce the motion blur effect of recording scan data in a dynamic environment (AGV for instance), but do not require all scan data at high frequency.
The hardware timestamp provides a highly precise synchronization of the sensor’s raw system time with the system time of an external client. This eliminates latency time and jitter of the software synchronization via Ethernet, leading to a synchronization accuracy of less than 1 ms. It also improves position accuracy during navigation of automated guided vehicles.
