The present application relates to a method for guiding and controlling the recovery of a drone, and belongs to the technical field of drone recovery. The method includes: obtaining environmental data; simulating the visibility of a first mark, a second mark, and a third mark according to the environmental data based on a preset simulation model; obtaining the first time consumed by the drone to identify the first mark, the second time consumed by the drone to identify the second mark, and the third time consumed by the drone to identify the third mark; based on a preset matching model, calculating the first speed of the drone moving from the visibility of the first mark to the visibility of the second mark according to the first time, calculating the second speed of the drone moving from the visibility of the second mark to the visibility of the third mark according to the second time, and calculating the third speed of the drone moving from the visibility of the third mark to the stop state according to the third time; obtaining and outputting target recovery data according to the first speed, the second speed, and the third speed. The present application can ensure the safe recovery of the drone into the nest system.
