Mapping correction method and apparatus, and storage medium

A mapping correction method, performed by a display device, comprising:

• determining an initial correction position;
• issuing a rewinding instruction to control a lawn mowing robot to rewind toward an original mapping trajectory;
• obtaining an intersection position between the lawn mower and the original mapping trajectory during the rewinding process, and determining the intersection position as a target correction position;
• when the lawn mowing robot intersects with the original mapping trajectory, detecting a second signal strength value of the lawn mowing robot at the intersection position;
• when the second signal strength value is less than a second preset threshold, continuing to perform the step of rewinding toward the original mapping trajectory;
• deleting a portion of the mapping trajectory between the target correction position and the initial correction position, and continuing the mapping based on the target correction position.

An electronic device, characterized by comprising a lawn mowing robot and a display device, the lawn mowing robot comprises a first processor and a first memory, the first memory is configured to store one or more first programs and is configured to be executed by the first processor, the first programs comprise instructions for performing operations including:

• obtaining an initial correction position;
• obtaining a rewinding instruction to rewind toward an original mapping trajectory;
• obtaining an intersection position between the lawn mowing robot and the original mapping trajectory during the rewinding process, and determining the intersection position as a target correction position;
• and
• when the lawn mowing robot intersects with the original mapping trajectory, detecting a second signal strength value of the lawn mowing robot at the intersection position;
• when the second signal strength value is less than a second preset threshold, continuing to perform the step of rewinding toward the original mapping trajectory;
• deleting a portion of the mapping trajectory between the target correction position and the initial correction position, and continuing the mapping based on the target correction position;
