Claim 12:
13. An assembly method for an optical lens, comprising:
pre-positioning a first lens member and a second lens member, wherein the first lens member comprises at least one first lens, the first lens member has a first optical region and a first structural region surrounding the first optical region, the second lens member comprises a second lens barrel and at least one second lens mounted in the second lens barrel, the second lens member has a second optical region and a second structural region surrounding the second optical region, the second structural region has a second top surface and the second top surface has a groove, the groove has a glue filling opening extending toward an outside of the second lens barrel, a first adhesive is filled into the groove through the glue filling opening, and wherein the pre-positioning enables the at least one first lens and the at least one second lens together constitute an imaging optical system;
determining a relative position of the first lens member and the second lens member by performing active calibration according to a measured imaging result of the imaging optical system; and
