Mapping correction method and related apparatus

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

• issuing, in response to an error occurring in a mapping trajectory of a lawn mowing robot, a correction instruction;
• controlling the lawn mowing robot to move, determining a target correction point in the mapping trajectory while the lawn mowing robot is moving, the target correction point being located at a distance greater than a predetermined distance from a start point of the mapping trajectory;
• and
• controlling the lawn mowing robot to return to the target correction point, and continuing a mapping operation based on a correct mapping trajectory and the target correction point, the correct mapping trajectory being a portion of the mapping trajectory between the start point and the target correction point□wherein the determining the target correction point while the lawn mowing robot is moving comprises:
• generating, based on a current position point of the lawn mowing robot, at least one connecting line to the mapping trajectory, each line forming an intersection point with the mapping trajectory;
• determining, for each connecting line, a distance between the corresponding intersection point and the current position point to obtain at least one distance value;
• and
• selecting a target distance value from the at least one distance value, acquiring the intersection point corresponding to the target distance value, and designating the intersection point as the target correction point.

A mapping correction device, performed by a lawn mowing robot, wherein the mapping correction device comprising:

• a receiving unit, a determining unit, and a mapping unit, wherein,
• the receiving unit is configured to receive, in response to an error occurring in a mapping trajectory of the lawn mowing robot, a correction instruction
• the determination unit is configured to determine a target correction point in the mapping trajectory while the lawn mowing robot is moving, the target correction point being located at a distance greater than a predetermined distance from a start point of the mapping trajectory;
• and
• the mapping unit is configured to return to the target correction point, and continuing a mapping operation based on a correct mapping trajectory and the target correction point, the correct mapping trajectory being a portion of the mapping trajectory between the start point and the target correction point;
• wherein the determination unit is further configured to:
• generate, based on a current position point of the lawn mowing robot, at least one connecting line to the mapping trajectory, each connecting line forming an intersection point with the mapping trajectory;
• determine, for each connecting line, a distance between the corresponding intersection point and the current position point to obtain at least one distance value;
• and
• select a target distance value from the at least one distance value, acquiring the intersection point corresponding to the target distance value, and designating the intersection point as the target correction point.
