1. A method of optically adjusting an image fusion LiDAR system, comprising:
presetting initial positions of a first detector and a second detector;
acquiring signal strengths of echo signals emitted by diffuse reflection at different positions on a background wall detected by the first detector;
determining a first mark position on the background wall according to the signal strengths of the echo signals of the echo signals; and
adjusting at least one of a position or an attitude of the second detector according to an echo signal emitted by diffuse reflection at the first mark position, wherein each of the first detector and the second detector comprises a linear array detector.
