Resolution / Quality

One of the most important considerations in laser scanning is the selection of resolution and quality of the laser scan.

Resolution Selector

The resolution selector (1) allows the user to set the resolution of their laser scan. Resolution determines the density of data collected and its specified in MPts.

Quality Selector

The quality selector (2) allows the user to set the quality of the scan for a given resolution. and quality determines the precision of that data.

Scan Duration

The scan duration (3) informs the user of the amount of time taken for the scan to complete. This is a function of the scan resolution and quality. Higher resolutions increase scanning time.

Scan Size

The scan size (4) informs the user of size of the scan files in pixels. Higher resolution scans take longer to process during the data processing phase.

Scan Points

The Scan Points (5) lets the user know how many points are present in their scan point cloud.

Scan Point Distance

The Scan Point Distance (6) helps users determine how close together are two points in a given area, 30ft in the case of the laser scanner.


Not all levels of quality are available for all resolution settings and the visualizer reflects the available options.

The help button (7) found in the top right corner of the home screen redirects users to this documentation if the users have any questions about the operation of the laser scanner simulator.

Students frequently find it difficult to visualize the relationship between resolution and quality. To help students with this visualization, a visualization feature has been added to the demonstrator.

The visualizer uses degrees of density of points in a given area to represent resolution and varying opacity and sizes to represent the quality. A higher density of points equates to a higher resolution and a smaller size point with higher opacity indicates a higher level of quality.
