Abstract:
1. A method for loading a medical appliance with a medicament and/or polymer, wherein the medical appliance contains a plurality of grooves or holes for being loaded with the medicament and/or polymer, characterized in comprising: capturing images of the grooves or holes of the medical appliance for multiple times using an image capturing device, each image containing a pattern of at least one entire the groove or hole; performing digital image processing on the image of each of the grooves or holes to obtain the pattern of each of the grooves or holes; calculating a central position of the pattern of each of the grooves or holes based on the pattern of each of the grooves or holes, and determining a loading position of each of the grooves or holes based on the central position; and adjusting a relative position between a loading device and the medical appliance to align an outlet of the loading device with the loading position of each of the grooves or holes, and loading each of the grooves or holes with the medicament and/or polymer; image converting that converts the image of each of the grooves or holes into a set of pixel points; image pre-processing that performs a filter processing on the set of pixel points to remove image noise; and image processing that processes the pre-processed image with a binary method to obtain the pattern of each of the grooves or holes, and assigning a value to each of the pixel points with the binary method based on a gray value of each of the pre-processed pixel points, designating a pixel point conforming with a preset value or value range as a target pixel point or a background pixel point, and connecting all the pixel points designated as the target pixel points or the background pixel points to obtain the pattern of each of the grooves or holes.
