1 . A camera verification piece, comprising:

a body; and

a verification structure provided at the body and for detection by visual detection equipment, wherein the verification structure is constructed to adapt to a to-be-detected structure on a to-be-detected part.

2 . The camera verification piece according to claim 1 , wherein a shape of the body is constructed to adapt to a shape of the to-be-detected part.

3 . The camera verification piece according to claim 2 , wherein a position of the verification structure on the body is configured to adapt to a position of the to-be-detected structure on the to-be-detected part.

4 . The camera verification piece according to claim 1 , wherein a shape of the verification structure is constructed to adapt to a shape of the to-be-detected structure.

5 . The camera verification piece according to claim 1 , wherein the verification structure comprises at least one of a verification hole, a verification groove, and a verification protrusion.

6 . The camera verification piece according to claim 1 , wherein the body is provided with a weight reduction slot, and the weight reduction slot is disposed avoiding the verification structure.

7 . The camera verification piece according to claim 1 , wherein the body comprises a body block and an insert block, the insert block is mounted on the body block, and the verification structure is formed on the insert block.
