Document Type and Number:
WIPO Patent Application WO/2021/134776
Kind Code:
A1
Abstract:
An apparatus comprises means for: obtaining a navigation path (2) between two locations (4, 6) which are separated by an obstacle (8), the navigation path (2) comprising an original vertex (10); modifying the navigation path (2) to comprise a displaced vertex (12), the displaced vertex (12) being displaced from the original vertex (10) in a direction away from a part of the obstacle (8) which is nearest to the original vertex (10); and smoothing a section of the navigation path (2) which passes via the displaced vertex (12). The smoothing of the section forms a curved path section (16) in the navigation path (2). The curved path section (16) comes no closer to the obstacle (8) than the original vertex (10).
