2 . The autonomous inspection system according to claim 1 , further comprising:
a topological map server configured to create a topological map for the inspection region.

3 . The autonomous inspection system according to claim 2 , wherein the plurality of scanning channels are arranged at intervals in a first direction,
the nodes for the first ends of the plurality of scanning channels are arranged in the first direction and the nodes for the second ends of the plurality of scanning channels are arranged in the first direction, and the node for the first end of any one of the plurality of scanning channels and the node for the second end of the any one of the plurality of scanning channels are arranged in a second direction.

4 . The autonomous inspection system according to claim 3 , further comprising:
a positioning device arranged on the inspection device and configured to determine a location information of the inspection device on the topological map; a processing device connected to the positioning device in communication and configured to acquire a node for the inspection device in the first direction or a node for the inspection device in the second direction in response to determining that the object to be inspected exists; and a controller electrically connected to the inspection device and configured to control a movement of the inspection device and a rotation of the inspection device after receiving an instruction from the processing device.

5 . The autonomous inspection system according to claim 4 , wherein the inspection device comprises:
an arm, wherein the positioning device is arranged on the arm; and a first vehicle body and a second vehicle body, wherein the first vehicle body and the second vehicle body are arranged at two ends of the arm, respectively, the first vehicle body, the arm and the second vehicle body are sequentially connected to define a passage, and the controller is configured to control a movement of the first vehicle body, a rotation of the first vehicle body, a movement of the second vehicle body, and a rotation of the second vehicle body, wherein when the inspection device performs a detection, the first vehicle body and the second vehicle body are driven by the controller so that the object to be inspected is located in the passage.

6 . The autonomous inspection system according to claim 5 , wherein the first laser radar device is arranged on an outer side of the first vehicle body and/or the first laser radar device is arranged on an outer side of the second vehicle body, the second laser radar device is arranged on an inner side of the first vehicle body or an inner side of the second vehicle body, and a coverage range of each of the first laser radar device and the second laser radar device is 360°.
