description The invention discloses a lens calibration method and a lens. The lens comprises a first lens group and a second lens group, wherein the calibration method comprises the following steps that: S10, structured light is emitted from a first side of the first lens group to obtain a first pattern formed after the structured light passes through the first lens group; S20, the second lens group is placed on the second side of the first lens group, the structured light is incident from the first side of the first lens group, and a second pattern formed after the structured light passes through the first lens group and the second lens group is obtained; and S30, the first pattern iscompared with the second pattern, if the similarity reaches a first preset value, the relative position of the first lens group and the second lens group is fixed, and if the similarity is lower than the first preset value, the position of the second lens group is adjusted, and the step S20 is repeated. The first lens group and the second l
