Route planning feasibility verification method and device

The invention belongs to the field of route planning, particularly relates to a route planning feasibility verification method and device, so as to solve the problems that in the prior art, effectiveroute planning feasibility verification equipment and method are lacked, and powerful basis is lacked for judging the feasibility of a route in route planning and auditing. The method comprises the following steps of acquiring a to-be-verified route and navigation information of a ship, determining the minimum safety distance according to the navigation information, generating and displaying a three-dimensional digital sand table model of the ship navigating in the sea area where the to-be-verified route is located through a ship intelligent navigation digital sand table system, and adjustingthe to-be-verified route through a digital sand table interaction unit to obtain an effective route, and judging the feasibility of route planning by comparing the effective route with the to-be-verified route.
