Optical adjustment for image fusion lidar systems

A system for optically adjusting an image fusion LiDAR system, comprising:

• a laser emitting module, a light splitting module, a photoelectric detector, an image detector, a visible light emitter, a background wall, and a controller, wherein:
• the photoelectric detector and the image detector are respectively located on two sides of the light splitting module;
• the laser emitting module is configured to emit a laser signal to the background wall;
• and the visible light emitter is configured to emit a visible light signal to the background wall;
• the light splitting module is configured to split an echo signal reflected by the background wall into visible light and laser;
• and the photoelectric detector is configured to receive the laser, and the image detector is configured to receive the visible light;
• and
• the controller is configured to:
• preset initial positions of a first detector and a second detector;
• acquire signal strengths of echo signals emitted by diffuse reflection at different positions on a background wall detected by the first detector;
• determine a first mark position on the background wall according to the signal strengths of the echo signals of the echo signals;
• and
• adjust 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.
