Claim 15:
16. The method according to claim 13, further comprising:
processing the first frame and analyze the first reflection pattern to determine whether the object is within the horizontal detection area and is not within the first portion;
in response to determining that the object is within the horizontal detection area and is not within the first portion, calculating a predetermined angle according to a position of the object in the horizontal detection area, and controlling the autonomous robot to rotate with the predetermined angle through the driving circuit and the plurality of wheels, such that the object is within the rotated first portion of the rotated horizontal detection area;
controlling the second light source to scan the rotated first vertical detection area by emitting the first vertical linear light;
controlling the light sensor to capture a sixth frame by receiving sixth reflective lights from the first vertical detection area; and
processing the sixth frame to obtain a sixth reflection pattern, and analyzing the sixth reflection pattern to determine whether the object is detected by misjudgment caused by the first reflective lights.
