description The invention discloses a high-precision optical guidance local imaging method. An imaging camera, an imaging lens and an optical axis translation optical path assembly are used for shooting and positioning a workpiece. The method comprises the following steps: (1) adjusting the pixel quantity and resolution of an imaging camera, the imaging camera shooting and positioning a workpiece by adoptinglow pixel quantity/low resolution, and simultaneously ensuring that all workpiece feature points of the positioned workpiece are shot; (2) adjusting an imaging camera and an imaging lens to improve the image resolution in the range of the workpiece feature points of the positioned workpiece; (3) adjusting an optical axis translation optical path assembly to obtain an imaging local area and an imaging invalid area, and shielding the imaging invalid area between the two workpiece feature points to be imaged into an imaging camera; (4) imaging the local area of the workpiece feature point to an imaging camera, so that th
