7. Wat is the angle of divergence?
The angle formed by two rays of a luminous beam in a given plane, the intensity within the angle
being at least equal to an assigned percentage of the maximum of the curve of intensity
distribution in that plane.
Most often the plane is either vertical (vertical divergence) or horizontal (horizontal divergence).
8. Bring out the main characteristics of a phase shift scanner.
Skänneri töötamise kiirus ulatub miljonitiesse p/s.
Skänneri töötamisraadius on aga suhteliselt väike <79m
9. Bring out the main characteristics of a time flight scanner.
Skänneri töötamise kiirus on aeglasem, ulatub tuhandetesse p/s – point
per sek.
Skänneri töötamisraadius on oluliselt suurem <1400m
10. What are the effects of scanning geometry to the point cloud?
Punktipilv on ruumiliselt laiali olevate punktide kogum, milles
igale punktile on määratud ruumilised koordinaadid.Tavaliselt
