4 . A detection method, applied to the detection apparatus according to claim 1 , the method comprising:

obtaining the first control instruction, wherein the first control instruction comprises the compensation information; and

controlling, based on the compensation information in the first control instruction, the first sliding assembly to move in the first direction to drive the first camera to move close to or away from the material to be photographed.

5 . The detection method according to claim 4 , further comprising:

controlling, based on the second control instruction, the rotating assembly to rotate in the preset rotation direction to drive the first camera to rotate.

6 . The detection method according to claim 5 , further comprising:

obtaining the third control instruction; and

controlling, based on the center position in the third control instruction, the second sliding assembly to move in the second direction to drive the first camera to move in the second direction.

7 . The detection method according to claim 6 , further comprising:

controlling, based on a fourth control instruction, the second sliding assembly to move in a third direction to drive a second camera to move in the third direction.

8 . The detection method according to claim 6 , wherein controlling, based on the center position in the third control instruction, the second sliding assembly to move in the second direction comprises:
