Boresight center automatic alignment system, apparatus and method

Abstract

The application belongs to the field of laser processing, and discloses a visual axis center automatic alignment system, device and method. The system comprises: an imaging module for acquiring a corneal topography; an adjusting module for: S1: determining the deflection angle of the visual axis around the x-axis and the y-axis according to the corneal topography; generating first scanning trajectory data according to the corneal topography and preset micro-lens parameters; performing three-dimensional rotation transformation on the first scanning trajectory data; S2: dividing the three-dimensional point cloud data obtained in S1 into slice point cloud data of different z-axis planes, fitting to obtain a fitting elliptical trajectory of each layer, and judging the light emitting point information on the fitting elliptical trajectory; generating a plurality of concentric elliptical trajectories according to the fitting elliptical trajectory of each layer and the light emitting point information, and forming a shape envelope of the preset micro-lens. The system of the application re-samples and fits the first scanning trajectory data, realizes the movement compensation of the eyeball deflection axis, and thus improves the accuracy and effect of the visual axis center automatic alignment.
