Image stitching method, device and medium for microscopic topography three-dimensional reconstruction

Abstract

The application relates to an image splicing method, device and medium for micro-morphology three-dimensional reconstruction. The method comprises the following steps: arranging a plane flat crystal on a stage, leveling the stage to obtain a leveled stage; obtaining multiple local plane flat crystal images of the plane flat crystal in a calibration region according to the leveled stage; performing plane fitting calibration according to height data of the multiple local plane flat crystal images to obtain calibration data in the calibration region; obtaining multiple to-be-spliced images of a workpiece on the plane flat crystal; performing height compensation on the multiple to-be-spliced images according to the calibration data and splicing image coordinates of the multiple to-be-spliced images to obtain multiple candidate splicing images; and performing superimposed splicing according to the multiple candidate splicing images to obtain a workpiece splicing image. The method can calibrate the height of each image data, and high-precision splicing between images can be realized based on the position coordinates of the image data after calibration.
