1. A line laser module, configured for use in an autonomous mobile device, and comprising:
a fixed base, and
a camera and a line laser emitter arranged on the fixed base, wherein
the line laser emitter is provided with the camera, and configured to emit a laser beam with a linear projection;
the camera is configured to operate in conjunction with the line laser emitter, and to capture an environmental image; and
the fixed base comprises a movable element, thereby enabling an orientation angle and a rotation angle of the line laser emitter to be adjustable, wherein
the fixed base comprises a body, end portions and a connection element, the end portions being located on respective sides of the body,
the camera is arranged on the body, and the line laser emitter is inserted into the connection element,
the line laser emitter is rotatably connected to the connection element to adjust the rotation angle of the line laser emitter,
the connection element is movably connected to the end portions to adjust the orientation angle of the line laser emitter, and
the connection element is provided with a through-hole, the line laser emitter is inserted into the connection element via the through-hole, and the line laser emitter is configured to rotate within the through-hole for adjusting the rotation angle of the line laser emitter.
